Research Summaries

Often faculty members are not aware of the most cutting edge or up-to-date educational technology trends that exist and how these tools can be used in the classroom. The purpose of these Research Summaries is to provide comprehensive reviews of research articles on these technologies and pedagogies. These summaries are based on empirical research using technology to enhance instruction.


Animation

 


Does animation improve comprehension?

Animation: Does animation improve comprehension?

Summary :

In 1996 Large, Beheshti, Breuleux, & Renaud found that animation and audio/visual presentations enhance comprehension but did not improve students’ ability to recall. Animation seems to be more effective with procedural text than descriptive text (Large, Beheshti, Breuleux, & Renaud, 1994).

Ariew & Ercetin discovered that for intermediate second language learners some video annotations have a negative impact on reading comprehension.

Young learners need a combination of visual and verbal information to maximize comprehension (Panagiotakopoulos, Ioannidis, 2002).

Grade 6 primary schools students in Montreal area. Majority were 12 year olds but some were 11. A total of 122 students participated.

 

To determine whether a complex descriptive text is enhanced by animation so long as the animation exhibits close semantic links with the text.

To explore the importance of captions in linking an animation with a descriptive text so as to increase comprehension of the text.

To investigate the relationship between spatial ability and students’ ability to recall and comprehend a text or a text enhanced with still images and animation.

Animation significantly enhanced comprehension of a descriptive text.

The addition of the animation to text did not produce significant gains in students’ ability to recall the text, identify its main themes, or answer questions on it.

On average, students with higher spatial abilities performed better than those with low spatial abilities on propositional recall, answering multiple choice questions, thematic recall, and problem solving.

Brewer, N., Harvey, S., & Semmler, C. (2004). Improving Comprehension of Jury Instructions with Audio-Visual Presentation. Applied Cognitive Psychology, 18, 765-776.

90 law undergraduate students (38 males and 52 females) and 90 legally untrained adults (41 male and 49 female).

To examine whether mock-jurors’ comprehension of a judge’s instructions on the law of self-defense was enhanced by an instructional format that combined audio-visual presentation with a flowchart?

Audio-visual format produced a marked improvement in comprehension: verdict accuracy, a multiple-choice or recognition test, a paraphrase or recall measure, and a scenario measure that involved transfer of legal knowledge to novel fact situations.

Audio-visual instructional format produced an improvement in novices’ comprehension.

The distinctive role of audio-visual instructional format from the visual flow chart was not determinable from this study.

120 grade 6 students

Does the addition of still images, animation and sound to text enhance any information product?

What is the role of complexity and text type (descriptive and procedural) in influencing the impact of animation?

If the learning objective is to understand the principles underlying text, then animation seems to enhance a text.

If the objective is to memorize information so that it can be regurgitated as completely and accurately as possible, text alone may be more successful.

Animation was more effective when used with procedural rather than descriptive text.

103 adult intermediate and advance level adult ESL learners.

Do different types of hypermedia annotations facilitate learning?

Does this depend on the proficiency levels of the students?

Learners interact with text differently according to their proficiency level and prior knowledge.

Video annotations had negative impact on reading comprehension for intermediate learners, which suggests that video may be distracting to them

Panagiotakopoulos, C.T., & Ioannidis, G.S. (2002). Assessing children’s understanding of basic time concepts through multimedia software. Computers and Education, 38 , 331-349.

374 nursery and school-aged children in 3 nursery schools and 3 elementary schools in Greece.

What is the role of computers with multimedia software in assessing the perception of the basic time concepts by children?

The presentation method employing the use of multimedia is preferable when:

The environment through which the time concept is examined is not static but involves movement or changes 2. There are facets, which can be emphasized through the use of multimedia so as to assist the child and to avoid misleading its judgment 3. a high degree of accuracy and precision is called for, when trying to avoid the introduction of unrelated details likely to mislead the child.

When visual and verbal information was combined with sound information, students’ comprehension was enhanced.


How does animation affect cognitve load?

Video: How does video affect cognitive load?

Summary :

Five modalities were tested the text, picture, film clip, audio-only, and audio-video instructions.

Based on the findings for the three modalities (text, pictures, film clip) it was seen that film clips and pictures required less cognitive load to interact. Because most participants in the film clip condition almost never practiced the exercises. They also had most movements correctly executed compared to text and pictures. Moreover, most people preferred the film clips condition to the text and picture condition. However, more learning took place under the picture condition rather than film clip condition. Furthermore, participants in the picture condition needed less time for execution than participants in the film clip condition.

Based on the findings for two modalities (audio-video and audio only) it was seen that audio-only condition required less cognitive load to interact. This is because in the audio-video condition participants had to use two channels to process the information. And when people are under high cognitive load they form biased impressions than people under low cognitive load.

Experiment 1: 30 young adults, between 18 and 30 years of age. 15 male and 15 female.

The participants were randomly assigned to an experimental condition.

Experiment 2: 26 young adults between 18 and 25 yrs age. 13 male and 13 female. None participated in the first study.

The purpose of the study was to test the effects of task difficulty and information modality (comparing dynamic visuals with static visuals and text) on learning a specific class of procedural tasks, namely exercises aiming at the prevention of Repetitive Strain Injury (RSI). The term CANS (short for Complaints of Arm, Neck and/or Shoulders) was introduced as an alternative term.

Experiment 1: The participants learn and execute 20 RSI prevention exercises in two degrees of difficulty. The following measurement were tested: the influence of presenting and instruction in text, picture or film clips on learning times, amount of practicing during learning, execution times, and number of execution errors.

The experiment had a 3 (information modality: dynamic visual [film clip], static visual [picture], text) X 2 as between participants variable and difficulty degree (easy, difficult) as within participants variable, and with learning times, amount of practicing during learning, execution times, and number of correctly executed exercises as dependent variable.

Experiment 2: Participants were asked which instructional format (text, picture, film clips) they preferred in a forced choice experiment.

The experiment had a 3 modality (text, picture, film) X 2 difficulty degree (difficult, easy) factorial design.

Experiment 1

Learning times:

Modality: Participants in the picture condition required the shortest learning times, participants in the text condition had the longest learning times, and learning for film clips was in between the two.

Difficulty: If was found that the difficulty degree had an effect on the amount of time to learn the exercise. But there was no significant differences the difficulty degree and information modalities were found.

Practicing time:

Modality: Participants in film clip condition almost never practiced, while in picture condition they practiced about fifth of the exercises, and in the text condition participants practiced about half of the exercise.

Difficulty: Participants practiced the difficult exercises more often than easy ones.

Execution times:

Modality: Participants in the text condition had much longer execution times than those in the picture and film clip condition. Participants in picture condition needed somewhat less time for execution than the participants in the film clip condition, but the difference was relatively small.

Difficulty: The instruction in text was more difficult than the instruction for pictures and film. There was no significant interaction between difficulty degree and information modality.

Correct Execution:

Modality: The participants who watches the film clip executed the most movements correctly.

Difficulty: The participants executed the easy exercises correctly than the difficult ones. In the film clip condition, both easy and difficult exercises were almost executed correctly. In the text and picture condition however, easy exercises were performed correctly more often than difficult exercises.

Subjective satisfaction:

Modality: Had no effect on the subjective satisfaction regarding the web site and the exercise. And no effect was found between the three conditions for web site and for the exercises.

Experiment 2

The results showed that for all exercises most participants preferred the film clips for illustrating the RSI exercises.

For all exercises the majority of the participants preferred the film clip to text and pictures.

Interestingly, for the first easy exercises the participants preferred the film clip and text to the instruction in a picture. For the second easy exercise the participants preferred the film clip and picture to the instruction in text.

Study 1: 71 undergraduates from the industrial management program at Carneige Mellon University who volunteered to get extra credit points toward course grade. All participants learned English as their first language.

The study was a 2 (low [audio only] or high [audio-video] amount of information) X 2 (poor or good signal clarity) within-subjects design.

Study 2: 70 undergraduates in the business program at Carnegie Mellon University who volunteered to get extra credit toward course grades. All participants had learned English as their first language. Five participants were suspicious of the priming manipulation and were removed from the analysis.

The study was a 2 (positive or negative) X 2 (low or high) design with priming and cognitive load as independent between-subject variables.

Hypothesis 1 : interacting over audio-video will generate a higher cognitive load than interacting over audio only.

Hypothesis 2: interacting over media with poor signal clarity (TV-quality) will result in a higher cognitive load than interacting over media with good signal clarity (PC-quality).

Hypothesis 3: Increased cognitive load will result in impressions more biased toward a primed trait.

Hypothesis 4: Communication over communication technology high in cognitive load will result in impressions more biased toward a primed trait than will communication over communication technology low in cognitive load.

Purpose of Study 1: Was to examine the relationship between two dimensions of communication technology and cognitive load.

Purpose of Study 2: Was to test the effect of cognitive load on impression formation.

Study 1

Hypothesis 1: Suggested that communication technology can increase cognitive load (H1). The participants in this study constantly made more errors in audio-video than in audio-only conditions. Thus, showing that more cognitive load is required to interact over an audio-video than over an audio-only system. Also, supporting the idea that having to process more channels and more screens of information may increase cognitive load.

Hypothesis 2: There was less support for the idea that poor signal quality increases cognitive load.

Study 2

The results of study 2 confirmed that people under cognitive load rely more heavily on the use of a negative prime when forming impressions than do people under low cognitive load.

Hypothesis 3: Confirmed that high cognitive load can lead to biased impressions (impressions biased toward a primed construct, thus suggesting less systematic processing of individuated information about the target).

Hypothesis 4: Participants who interacted over audio-video were more influenced by the primed-trait than were participants who interacted over audio only. A contrast comparing audio only to audio-video in the negative-trait primed condition indicated that participants in the audio-video condition were more vulnerable to the negative prime than participants in the audio-only condition. Thus, suggesting that impressions of people communicating over an audio-video medium may be more biased toward a primed trait than impressions of people communicating over audio only.


Is animation more effective when complemented with other strategies?

Animation: Is animation more effective when complemented with other strategies?

Summary:

Animation tends to be more effective when complemented with other strategies, especially direct instruction.  In a study Lin & Dwyer proved that static visual treatment is just as effective as varied animated treatment in learner achievement.   When the static visual treatment is highly developed, it can be just as effective as animation.   The main idea of certain material is easily recalled from animated node-link maps rather than static maps or even animated text.   Huang explains, computer based instructional units are also effective in the cognitive psychomotor skill learning areas.   Kidwai, Munyofu, Swain, Ausman, Lin, & Dwyer, determined that animation impacts factual and contextual learning but not higher order learning.

22 third-grade children randomly assigned to control (n=11) and experimental groups (n=11)

The purpose of the study was to determine whether mere animation or animation with supplemental instruction is more efficient in learning and retention of unfamiliar words. The used material was an electronic book of poetry for children.

The children with supplemental instructions in conjunction with animation scored significantly higher (M=5.00, SD=0.89) than the children who did not receive synonyms, definitions and questions in addtition to animation (M=2.91, SD=1.30).

93 college level learners randomly assigned into 1 control and 3 experimental groups

The purpose of the study was to investigate effects of instructional enhancements (advance organizers, adjunct questions and feedback) in conjunction with animation on learners' information acquisition.

There were insignificant differences in learner achievement among different treatment groups. Static visual treatment alone was found to be as effective as the animated treatments (advance organizers, questions and feedback) in facilitating learner achievement.

133 college students randomly assigned to one of the four experimental conditions: static node-link map (concept map), static text, animated node-link map and animated text.

The purpose of the study was to determine efficiency differences of static node-link maps and text or animated node-link maps and text on learners' information acquisition.

The participants showed the highest level of information acquisition after using animated node-link maps (M=22.40, SD=10.48) as opposed to other conditions (M=17.24, 14.30, 10.13; SD=10.72, 12.57, 12.00). The research suggests using concept maps in conjunction with animation as an effective way to improve learners' information acquisition.

N=68 who were university students from four sections of beginning tennis classes at the Chung Cheng University in Taiwan. The participants were categorized into two groups: one group having high prior knowledge and the other group having low prior knowledge. Then, they were randomly assigned to a computer and completed one of three treatment; spoken audio only-KOR, knowledge of the correct response-KCR (voice with text), and elaboration feedback-EF (voice with text, visual and animation).

  • The purpose of the study was to investigate the effects of digitized feedback and ability on the achievement of college students during computer-based instruction.
  • The research also studied the achievement of high and low-prior knowledge students when compared among different types of feedback treatments.
  • After the learners took the computer-based instructional unit that include an interactive video lesson on cognitive areas of tennis skill performance, the results found that they perform better under the elaborative feedback (EF-voice with text, visual and animation) condition than the KOR and KCR feedback conditions.
  • Even though the study shows that the elaborative feedback was most beneficial for cognitive areas of psychomotor skill learning, but there was no significant difference between level of ability and type of feedback.
  • In addition, the study indicated that high ability students in the elaborative feedback group reported the lowest attitude scores because they might feel they got too much information that might distract with their learning

Approximately 90 undergraduate students were randomly assigned to three treatments (control, simple and complex). The participants were taken the four dependent measures; Drawing, Identification, Terminology, and Comprehension after they received the respective instructional presentation.

The purpose of the study was to investigate the instructional effectiveness of two visual scaffolding strategies (simple and complex scaffolding) used to complement animated instruction.

  •  The results found that students’ scores were achieved on the drawing, identification, terminology and comprehension tests.
  • Thus, the result of this study shows that animation has a significant impact on acquisition of factual and conceptual knowledge.
  • However, the researchers found the insignificant results in the contributions of visual scaffolding in complementing animation.
  • The insignificant impact on students’ performance on measures of higher order learning might be occurred because positive effect of visual scaffolding and animation may be cancelled by an increase in task complexity.


M-Learning

 

How can I use M-Learning in higher education?

M-Learning: How can I use M-Learning in the classroom

Summary:

Mobile technology is one of the latest innovations that can be integrated into any type of class structure.  M-learning (the use of mobile technologies in teaching/training) is a complimentary means for student and instructor social interaction, motivation and learning (Zurita, Nussbaum, 2007).  Motiwalla found, students of the 21st century view m-learning as an important supplementary role to e-learning.  Fisher & Baird believe that mobile technology creates community generated content and a community of learners and thus creates a more communicative or interactive setting rather than a content based setting.

Emerging nations that face challenges in designing and developing relevant learning environments are finding that mobile technologies are convenient, flexible and cost effective (Motiwalla, 2007).  Motiwalla’s study also found that schools and universities are notifying students through SMS.  These mobile notifications increase the number of students who register on-time and increase attendance at seminars and presentations.  Brown noted, paper and postage notifications are 20 times higher in cost and tend to be ignored or thrown away. 

Initially the m-learning application can be a great inhibitor causing anxiety due to the phone keypad and screen (Wang, 2007) (Motiwalla, 2007).  Brown noted, mobile technology should only be used as a complimentary tool, not as a primary mode of education.  Synchronous sharing can become problematic as a result of unreliable, unstable mobile access (Goh & Kinshuk, 2006).  Goh & Kinshuk also confirmed that students will be better served with mobile technologies once dynamic rather than static web pages are developed.

To investigate the usage of mobile learning in distance learning in higher education.

There were sixty three participants in the study. They were undergraduate and graduate students at Massachusetts Lowell College of Management.

A prototype application was developed to link wireless/handheld (W/H) devices to three course websites. The application framework consists of two levels or two phases of research and analysis: mobile connectivity and e-learning. Two phases were followed by two attitudinal surveys: in phase one the emphasis was only on student satisfaction with our application, while in phase two the emphasis was on student satisfaction and their general perceptions on the role of m-learning in higher education. The participants needed to access the courses from both regular PC/notebook internet and m-learning.

The m-learning applications were pilot-tested for two semesters. The students used the m-learning environment with a variety of wireless/handheld (W/H) devices and reported their experiences through a survey and interviews at the end of the semester for two semesters. The attitudinal surveys used a 5-point Likert scale with strongly agree as 5, neutral as 3 and strongly disagree as 1 on the Likert scale

First phase: The students found the m-learning useful and a good complimentary tool for the classroom interaction. They rated neutral on ease-of-use, but found the interaction tools easy for discussing course materials with other students and instructors. They found the mobile phone keypad and screens very difficult while navigating, reading and typing their messages. However, once they overcome this user-interface hurdle the m-learning applications used for classroom interaction were easier to understand.

Second phase: The students foresee m-learning as an effective learning tool or aid, providing flexible access from anywhere and convenient to use application. Students also perceive and important supplementary role for wireless/handheld devices in e-learning and are effective in delivering personalized content.

Brown, Tom H. (2005).Towards a model for m-learning in Africa. International Journal on E-Learning. 4.3, 299-316.

The population for the study was spread as follows:

100% full -time employees (teaching), 77.4% English second language speakers, 22.6% English first language speakers, 83.8% between the age of 31-50, 13.9% younger than 31, 66.4% are women, 97.3% non-white, 0.4% access to email, and 99.4% have mobile phone.

Tom H. Brown from the University of Pretoria, South Africa was intereseted in finding out more information about M-Learning in Africa. The main question that the research posed was why there is a move towards M-Learning in Africa? This question has been asked mainly because the people in Africa do not certainly fit the characteristics of the developing nations which fit the ideal population for M-Learning.

During the months of November 2002 to February 2003, SMS messages sent to students and adminstrative staff . The SMS messages to were to provide basic adminstrative information to staff and 5 SMS messages were sent to the learners as reminders of important dates for activities like contact classes, examination registration, examinations, notification of study material distribution.

The results from the research proved that M-Learning had a lot of advantages for the learners in Africa. There was an increase in the number students registering early for classes because they were getting their reminders on time via SMS. 95% of the students previously registered for contact sessions were attending the sessions because they were getting reminders through SMS Messages. The cost of distributing necessary information using print and postal services to the learners was 20 times higher than using the SMS. Another great advantage of using SMS was that it provided JIT(just-in-time) information as compared to the time it took to post the information.

There is a challenge to design and develop relevant learning environments, based on sound pedagogical principles that will ensure the optimization of learning in the m-learning environment.

E-Learning encompasses M-Learning and studies show that M-Learning serves more of a communication approach than a content approach. Therefore the major focus of M-Learning should be more on communication and interaction than on content.

M-Learning supports other forms of education and cannot be treated as a primary mode of education.

The most appropriate mobile device for learners in Africa is a mobile phone and possibilities and latest developments in mobile technologies must be tested against practicality, usability, and cost-effectiveness.

The authors of this article are concerned with the significance of the m-learning environment upon existing learning environments (such as distance learning, pedagogical/learning theory, and games/competition in learning), their implications, and the importance of tailoring web based information to mobile device formats.

The findings support the need for synchronous sharing within mobile access is necessitated due to the unreliable nature of current mobile access as opposed to fixed line access, and further research in the area of prefetching to reduce time needed for page loads, is suggested. The authors also advocate for developers to move towards dynamic rather than static pages.

Assess the students’ perceptions of the importance of being able to access learning resources.

 

Findings -

With the students surveyed:

  • Mobile technologies were mainly being used for clinical applications rather than learning applications.
  • Students showed a low level of awareness of the technology but placed a high value on the ability to access learning resources.

Implications –

  • Librarians play an important role in training students as use of new electronic resources increases.

Health professionals and students value e-journals and electronic databases because of their lack of immediate access to a physical library.

235 students (137 first year, 98 second year) completed the survey.

Purpose: The purpose of this study is to provide specific strategies that faculty could use to make mLearning environments more engaging and for enhance student-centered learning to meet the digital learning styles of the student population.

Method: Students had access to the Virtual Graffiti tool through a mobile phone number or the Web.

100% of the student population had access to a mobile-enabled device. The phone features helped learners with limited typing skills. It also allowed quick and easy connectivity and lowered the duration of interactions.

Questionnaire: The National College of Ireland provided a short questionnaire to all the students in Business Communications course. The feedback through the survey was got at the beginning of the semester. The survey was anonymous and voluntary.

Interview: several participants were interviewed after their experience with the mural building with mobile class activity i.e. mlearning class.

Findings from Survey

 

Student Learning Preferences

  • 67%: group work and interact have discussion with peers and instructor.
  • 17%: short lectures, embedded with professional experiences
  • 8%: straight teacher led lecture.

Learning and Technology

  • 91%: instructors and students use latest technologies
  • 98%: believe they play most responsible role in their learning.

Overall findings from Survey

  • Best lectures : 1/3 rd students said that characteristics like passion, motivation, charisma, approachable, creative, interesting, interactive were cited more frequently than other characteristics, as intelligent, knowledgeable, professionally experienced, strict, clarity, organized, and ability to control class.
  • Good Communication skills : was highly valued. Over half of the students wanted feedback on how things can be mad easier, written feedback, constructive criticism, direct answers, and continuous assessment.
  • 1 st and 2 nd year students : both expressed similar opinions. But the second year students wanted more critical thinking learning activities other than group discussion to practice problem solving decision making and teamwork skills. While first years prefer homework.

Findings from Interview/Class

 

    • Students expressed flexibility of the content and format in the event, and the fact that it was teacher-let.
    • High attendance and completion rates resulted from this approach.
    • Motivation and support were central to the whole process.
    • Good quality posts were produced, which were important outcome of the project as well as demonstrating participant-learners’ technical awareness.
    • Return posts to the Website after classroom event was another demonstration of its effectiveness, indicating they had positive experience.

Key Findings of the National College of Ireland mlearning project:

  • High attendance , high levels of participation and completion from learners.
  • Realization and publication of student-initiated, learner produced content to the classroom mural and Web.
  • Creation of an expanding model suited to the Irish curriculum, tried and tested in the classroom.
  • Awareness -raising of the potential uses of mobile technologies in education, and encouragement of curricular use of the resources produced in class.
  • The creation of a community of learners.
  • Creation of user and community generated content.

Evans, C. (2008). The effectiveness of m-learning in the form of podcast revision lectures in higher education. Computers & Education, 50, 491–498.

196 volunteers of first-year undergraduates in Business and Management at a university in London, UK. 96 female, 98 male (two did not specify).

Ages ranged from 18 to 25, with a mode of 19 and mean of 19.27.

Participants had access to school computers as well as their own personal computers. They were provided with a simple guide telling them how to access the podcast episodes via a PC or using an iPod, but were not otherwise given any special support.

For consistency, an RSS feed was not provided as one of the episodes was to be inaccessible until they had completed an online survey. The survey contained fifteen five-point

Likert-scale questions, two open-ended questions and six demographic.

H1: Learners believe that it is quicker to revise from podcasts than from notes.

H2: Learners believe that revising from podcasts is more effective than from notes or from a textbook.

H3: Learners feel more receptive to revision material delivered as a podcast than in a traditional revision lecture or a textbook.

H4: Learners feel they can relate more to the lecturer in a podcast than in a traditional revision lecture.

Out of the 194 students, 20% of them indicated that they listened to the podcasts on an iPod (14%) or other MP3 player (6%). The remaining 80% listened to them on a PC via the Web page.

The results show that students value the flexibility offered by podcasts in terms of the ability to study when and where you want. One quarter of them listened to them whilst traveling. Traveling is often a time when people engage in less cognitive activity. This suggests that podcasting can fill an important needs gap by allowing learners to continue the learning activities when it might not normally be possible. However, podcasts did not appear to offer much in the way of facilitating multi-tasking, with most people claiming that they did not undertake any other activities whilst listening to podcasts.

The question about listening to podcasts whilst doing something else was an attempt to draw out whether the mobile features of podcasting translate into any other activities than just traveling. With most people disagreeing, the indications are that traveling is the main mobile benefit.

The overall research aim was to determine whether revision podcasts enhance the learning process. The results provide support for three out of the four hypotheses suggesting that they do. The answers to the first pair of questions indicates that students believe that revision podcasts are a quicker way to revise than using their own notes.

The results from the second and third pairs of questions indicate that the students report that podcasts are more effective revision tools than textbooks, but not their own notes. This means that they claim that they learn more from the podcasts than reading the corresponding section from the textbook. The flexible nature of podcasts may mean that it is easier for learners to actively engage with material than when reading. The fact that they report that they do not find podcasts more effective than notes suggests that the summarizing format of the podcasts was of particular benefit in helping learners focus on the important aspects to the subject without getting sidetracked by detail.

The results from the fourth and fifth pair of questions indicate that the students report that they were more receptive to podcast material than material delivered in the form of a revision lecture or from the textbook. This suggests that learners may feel more engaged when listening to a podcast.

The results from the last question pair provide no evidence in support of the hypothesis that it is easier to relate to the lecturer in a podcast than in a revision lecture.

Taken together, these results provide good evidence to suggest that students think that podcasts enhance their learning process, as reported in their responses.

The student population for this study consisted of 63 students, both undergraduates and graduate students, from the University of Massachusetts, Lowell College of Management.

The purpose of the study was to develop a better understanding of the role of mobile technology in higher education. A prototype application that ran on PDA’s and cell phones was developed to link such devices to three websites. The study focused on two goals for evaluating the application developed for use on the mobile devices:

-Observe the usage of the application in a classroom setting with students and obtain feedback on the applications

-Determine students opinions on the role and value of m-learning applications

Results on the first goal indicated that the students considered the m-learning application useful and complimented their normal classroom interactions. Some students reported having difficulty using the phone keypads and difficulty navigating and reading the screens. The results, as collected using a survey, relating to the second goal indicated that the students felt that m-learning has the potential of being an effective learning tool, providing flexible access from anywhere.

How are businesses and educators using m-technologies and m-learning?

Currently, mobile technologies were in common use in some commercial sectors, but the use of mobile technologies purely for learning was rare.

Many educational providers recognize the benefits of m-learning but found adoption in the educational setting limited because...

-the age and ability of teachers and trainers

-the cost of providing m-learning devices and infrastructure

-the slow rate of change in large educational institutions

-mobile devices are not designed with the education market in mind

Suki, N. M. & Suki, N. M. (2007). Mobile phone usage for m-learning: comparing heavy and light mobile phone users. Emerald Group Publishing Limited, 24 (5), 355-365.

Data was collected from 436 (105 male, 331 female) respondents. About 98 percent of the respondents own a mobile phone and the rest own a smart phone or a PDA/ palmtop.

Purpose: Mobile technologies offer the opportunity to embed learning in a natural environment. The objective of the study is to examine how the usage of mobile phones for m-learning differs between heavy and light mobile phone users. Heavy mobile phone users are hypothesized to have access to/subscribe to or purchase mobile content (games: online, download; infotainment: news, sport; edutainment; entertainment; personalization :ring tone) within the last year than light mobile phone users, and to pay less money for mobile learning, its content and mobile games than light mobile phone users.

Method: About 600 questionnaires were distributed to mobile phone users in the Klang Valley (highly populated urban area in Malaysia). Out of which 436 were returned. Respondents were selected following a stratified random sampling technique, to represent a group of individuals who have the purchasing power and also the resources to access and use the internet, mobile commerce and mobile content.

Two-section questionnaire:

Section A: questions about users’ adoption level of mobile technologies usage and mobile content consumption, such as their level of experience of mobile technologies and content, the type of mobile content accessed within the last year, the frequency of access, subscription to, or purchase of mobile content.

Section B: questions covered the respondents demographics.

Significant differences were identified when comparing the usage of mobile phones for m-learning between heavy and light mobile phone users. It was found that heavy mobile phone users:

-access/subscribe to more than one type of mobile content

-have more frequent access to subscription

-purchased more mobile content within the last year 

-spent more money on mobile learning, its content and mobile games

With the emergence of new tools and media, mobile content can be a powerful means to increase tacit knowledge through the exploration of interactive multimedia and 3D animations for creative edutainment and communication in the future. Thus, mobile content needs to be developed specifically for mobiles, with clear images and good quality sound. 

Users are encouraged to come back and enjoy new segments and features.

Does video improve the transfer of knowledge?

Video: Does video improve the transferring of knowledge?

Summary:

In this cross-section of populations and purposes, video does improve the transferring of knowledge in the settings described; however, only at slight levels with certain populations.  When video (multimedia) is used for demonstrations on a college exam it is overwhelmingly welcomed.  However, in a traditional classroom setting, live instruction tends to be more motivating than any other method of delivery. 

In the area of short-term memory, both live and power point instructions were affective.

Miller, J. S., Stanley, I., & Moore, K. (2004). Videotaped Exercise Instruction: A randomized controlled trial in musculoskeletal physiotherapy. Physiotherapy Theory and Practice, 20, 145-154.

Patients with Low Back Pain (LBP) were 385 and Shoulder Pain (SP) were 165.

To compare the effectiveness of videotape with face to face instruction for two common musculoskeletal conditions. There were three groups. Two were provided with instructional videotapes, one featuring the treating physiotherapist, the other an anonymous physiotherapist; the third group was instructed via face to face methods. 

Patients in the videotape groups were prescribed more exercises and were more skilled in performing them than were the face to face group.

In terms of clinical progress, instruction by videotape was no more effective than face to face.


How does video affect cognitive load?

Video: How does video affect cognitive load?

Summary:

Five modalities were tested the text, picture, film clip, audio-only, and audio-video instructions.

Based on the findings for the three modalities (text, pictures, film clip) it was seen that film clips and pictures required less cognitive load to interact. Because most participants in the film clip condition almost never practiced the exercises. They also had most movements correctly executed compared to text and pictures. Moreover, most people preferred the film clips condition to the text and picture condition. However, more learning took place under the picture condition rather than film clip condition. Furthermore, participants in the picture condition needed less time for execution than participants in the film clip condition.

Based on the findings for two modalities (audio-video and audio only) it was seen that audio-only condition required less cognitive load to interact. This is because in the audio-video condition participants had to use two channels to process the information. And when people are under high cognitive load they form biased impressions than people under low cognitive load.

Experiment 1: 30 young adults, between 18 and 30 years of age. 15 male and 15 female.

The participants were randomly assigned to an experimental condition.

Experiment 2: 26 young adults between 18 and 25 yrs age. 13 male and 13 female. None participated in the first study.

The purpose of the study was to test the effects of task difficulty and information modality (comparing dynamic visuals with static visuals and text) on learning a specific class of procedural tasks, namely exercises aiming at the prevention of Repetitive Strain Injury (RSI). The term CANS (short for Complaints of Arm, Neck and/or Shoulders) was introduced as an alternative term.

Experiment 1: The participants learn and execute 20 RSI prevention exercises in two degrees of difficulty. The following measurement were tested: the influence of presenting and instruction in text, picture or film clips on learning times, amount of practicing during learning, execution times, and number of execution errors.

The experiment had a 3 (information modality: dynamic visual [film clip], static visual [picture], text) X 2 as between participants variable and difficulty degree (easy, difficult) as within participants variable, and with learning times, amount of practicing during learning, execution times, and number of correctly executed exercises as dependent variable.

Experiment 2: Participants were asked which instructional format (text, picture, film clips) they preferred in a forced choice experiment.

The experiment had a 3 modality (text, picture, film) X 2 difficulty degree (difficult, easy) factorial design.

Experiment 1

Learning times:

  • Modality: Participants in the picture condition required the shortest learning times, participants in the text condition had the longest learning times, and learning for film clips was in between the two.
  • Difficulty: If was found that the difficulty degree had an effect on the amount of time to learn the exercise. But there was no significant differences the difficulty degree and information modalities were found.

Practicing time:

  • Modality: Participants in film clip condition almost never practiced, while in picture condition they practiced about fifth of the exercises, and in the text condition participants practiced about half of the exercise.
  • Difficulty: Participants practiced the difficult exercises more often than easy ones.

Execution times:

  • Modality: Participants in the text condition had much longer execution times than those in the picture and film clip condition. Participants in picture condition needed somewhat less time for execution than the participants in the film clip condition, but the difference was relatively small.
  • Difficulty: The instruction in text was more difficult than the instruction for pictures and film. There was no significant interaction between difficulty degree and information modality.

Correct Execution:

  • Modality: The participants who watches the film clip executed the most movements correctly.
  • Difficulty: The participants executed the easy exercises correctly than the difficult ones. In the film clip condition, both easy and difficult exercises were almost executed correctly. In the text and picture condition however, easy exercises were performed correctly more often than difficult exercises.

Subjective satisfaction:

  • Modality: Had no effect on the subjective satisfaction regarding the web site and the exercise. And no effect was found between the three conditions for web site and for the exercises.

Experiment 2

  • The results showed that for all exercises most participants preferred the film clips for illustrating the RSI exercises.
  • For all exercises the majority of the participants preferred the film clip to text and pictures.
  • Interestingly, for the first easy exercises the participants preferred the film clip and text to the instruction in a picture. For the second easy exercise the participants preferred the film clip and picture to the instruction in text.

  • Study 1: 71 undergraduates from the industrial management program at Carneige Mellon University who volunteered to get extra credit points toward course grade. All participants learned English as their first language.

The study was a 2 (low [audio only] or high [audio-video] amount of information) X 2 (poor or good signal clarity) within-subjects design.

  • Study 2: 70 undergraduates in the business program at Carnegie Mellon University who volunteered to get extra credit toward course grades. All participants had learned English as their first language. Five participants were suspicious of the priming manipulation and were removed from the analysis.

The study was a 2 (positive or negative) X 2 (low or high) design with priming and cognitive load as independent between-subject variables.

Hypothesis 1: interacting over audio-video will generate a higher cognitive load than interacting over audio only.

Hypothesis 2: interacting over media with poor signal clarity (TV-quality) will result in a higher cognitive load than interacting over media with good signal clarity (PC-quality).

Hypothesis 3: Increased cognitive load will result in impressions more biased toward a primed trait.

Hypothesis 4: Communication over communication technology high in cognitive load will result in impressions more biased toward a primed trait than will communication over communication technology low in cognitive load.

Purpose of Study 1: Was to examine the relationship between two dimensions of communication technology and cognitive load.

Purpose of Study 2: Was to test the effect of cognitive load on impression formation.

Study 1

  • Hypothesis 1: Suggested that communication technology can increase cognitive load (H1). The participants in this study constantly made more errors in audio-video than in audio-only conditions. Thus, showing that more cognitive load is required to interact over an audio-video than over an audio-only system. Also, supporting the idea that having to process more channels and more screens of information may increase cognitive load.
  • Hypothesis 2: There was less support for the idea that poor signal quality increases cognitive load.

Study 2

  • The results of study 2 confirmed that people under cognitive load rely more heavily on the use of a negative prime when forming impressions than do people under low cognitive load.
  • Hypothesis 3: Confirmed that high cognitive load can lead to biased impressions (impressions biased toward a primed construct, thus suggesting less systematic processing of individuated information about the target).
  • Hypothesis 4: Participants who interacted over audio-video were more influenced by the primed-trait than were participants who interacted over audio only. A contrast comparing audio only to audio-video in the negative-trait primed condition indicated that participants in the audio-video condition were more vulnerable to the negative prime than participants in the audio-only condition. Thus, suggesting that impressions of people communicating over an audio-video medium may be more biased toward a primed trait than impressions of people communicating over audio only.

How does video aid in memory retention?

Video: How does video aid in memory retention?

Summary:

In this cross-section of articles, video seemed to aid retention and learning in older adults while in younger adults and children, the vehicle by which training is taught either showed no change or live training/teaching proved to be better for retention. The Mykityshy (et al) article found that video followed by practice was the best method of gaining retention. In the Roebers (et al) "It's Magic" article, video came in second (to live performance) in retention and surety of correct responses. This article is only one of many studies related to this--an important area of research in child psychology and criminal law, etc.--most finding that video and television can actually skewer the memory of child witnesses. The Rossiter (et al) article depicts that longer seen images in video are most easily remembered as well as those which affect the front left hemisphere of the brain (though it is never made clear what types of images affect that part of the brain). In the Weeks (et al) article, researchers found that dynamic modeling (that in which video is used) produced a higher rate of retention than static modeling (with still pictures).

30 younger adults between the ages of 17 and 24 years.

30 older adults between the ages of 65 and 74 years.

The purpose of the study was to directly compare two media (written vs. video instructions) for training younger and older adults to use a home medical device.

Both younger and older adults were received training on use of a blood glucose meter via either a user manual (a text guide with pictures) or an instructional video.

The participants were tested immediately after the training and then retested after a 2-week retention interval session.

The type of training does not influence the performance of younger adults either immediately after training or after the 2-week retention.

The results of the study indicated that the older adults perform better when using the video instruction. However, the older adults show declines in performance during the 2-week retention session due to the nonuse of the instruction.

The study showed that video training with immediate performance results in better learning by older adults, relative to a written manual with pictures, and that skill learning may not be retained as well by older adults as by younger adults.

The effect of age differences is a critical factor in the development of effective training programs.

Roebers, C. et al. (2004). “It’s Magic!” The Effects of Presentation Modality on Children’s Event Memory, Suggestability, and Confidence Judgements. Journal of Experimental Child Psychology, 87(), 320-335.

270 children from Bavaria, Germany in 3 age groups (90—51 girls and 39 boys--5/6 yr olds, 92—49 girls and 43 boys--7/8 yr olds and 88—43 girls and 45 boys--9/10 yr olds).

Of these children, each age group was divided into three subgroups. For the 5/6 group, 30 (14 girls, 16 boys) were place in the live group, 29 (19 girls and 10 boys) were placed in the video group and 31 (18 girls and 13 boys) in the slide show group. 7/8—30 (16 girls, 14 boys) in live, 30 (15 girls, 15 boys) in video and 32 (18 girls, 14 boys) in slide show. 9/10—30 (15 girls, 15 boys) in live, 30 (11 girls, 19 boys) in video and 28 (17 girls, 11 boys) in slide show.

Researchers wanted to find out how accurate children’s recall of events held up after different types of presentations: live action, video and slide show.

They also wanted to see how children could defend against false information posed to them about the three types of presentation. (These types of studies are especially valuable to the criminal justice field where children must sometimes be called to testify and their recall of events can be brought into question.)

Correct answers to non-leading questions ranged the following:

  • 5/6—53.5% live, 51.3% video, 49% slide show.
  • 7/8—62.2% live, 56.9% video, 51.3% slide show.
  • 9/10—64.3% live, 64.7% video, 57.4% slide show.

Confidence judgments after questions (1=very unsure, 5=very sure):

  • 5/6—live—4.7 correct, 4.3 incorrect
  • --video—4.8 correct, 4.3 incorrect
  • --slide show—4.6 correct, 4.2 incorrect
  • 7/8—live—4.7 correct, 4 incorrect
  • --video—4.7 correct, 3.4 incorrect
  • --slide show—4.6 correct, 4.1 incorrect
  • 9/10—live—4.6 correct, 3.9 incorrect
  • --video—4.5 correct, 3.5 incorrect
  • --slide show—4.6 correct, 3.3 incorrect.

Percentages of correct answers to misleading questions:

  • 5/6—54.1 live, 47.9 video, 41.7 slide show
  • 7/8—68.2 live, 53.9 video, 48.9 slide show
  • 9/10—73.3 live, 63.5 video, 58 slide show

The outcome of this study suggests that children are better able to remember events and guard against misleading information when they witnessed the action live. Of the media, video recall came out on top of slide show.

35 Austrailian women, aged 25-35 who were primary shoppers of their households. These women were prescreened to be right-handed, meaning their left-brains were predominate.

Advertisers wanted to find out what frames of video would be remembered by viewers one week later. Scientists used brain imaging to see how the hemispheres of the brain reacted to each frame and how they reacted when recognition of certain frames occurred.

Advertisers hope this kind of research will help them better understand and predict what kinds of visuals will be remembered by consumers.

On the questionnaire, participants recognized 52.8% of images seen previously. They had a 20.2% rate of “false positives,” remembering images that they had not been shown. There was a 47.2% rate of “false negatives,” or not remembering scenes that had been previously shown, with a 79.8% rate of accurately identifying images and scenes that they had not previously been shown.

Of items with shorter exposure (<1.5 secs), 41.1% were remembered. Of longer exposure (?1.5 secs), 62.8% were remembered.

The SSVEP part of the study showed that, in fast SSVEP response frames, the left hemisphere responded 66% of the time in recognition, compared to 58.7% both hemispheres and 53.8% right hemisphere. For slower recognition, the right hemisphere came in at 54.2%, versus both hemispheres at 45.3% and the left hemisphere at 37.9%.

The researchers believe this shows that longer images are necessary to be remembered and that, for faster recognition of the image, the image should affect the front left hemisphere.

Ten male and ten female university students were randomly assigned to either a dynamic demonstration (videotape instruction) group or a static demonstration group (still-potograph illustrations) for an acquisistion session and retention test 24 hours apart.

The purpose of this study was to compare videotape instruction (dynamic modeling) to instruction via illustraitons (static modeling) for influcing the accuracy of movement form, motivation perceptions, and confidence of subjects performing simple and complex viusally guided and non-visually guided exercises. This study was hypothesized that accuracy of fomr in acquistion and retention would be greather in the group viewing the dynamic demonstrations when compared to the group viewing static demonstrations fro each type of exercise.

The results of this study indicated that dynamic modeling (videotape instruction) score higher than static instruction both in the presence of the acquisition phase and in the retention phase.

In terms of more functional memory representation, the dynamic mode of modeling with videotape instruction is more effective than that of the static illustrations.

 

 


Is video an effective strategy in improving learning performance?

Video: Is video an effective strategy in improving learning performance?

Summary:

The studies contained in this technical report all produce favorable findings for the affect of video on learning performance. The first two studies examined video as it compared to not using video. The first study used 3 rd and 8 th grade students, and attempted to ascertain basic criteria of video based education It found that students who received video instruction scored higher than those who did not. Researchers of this study caution that the change may not be entirely related to video, and recommend continued trials.

The second study is much of the information that goes into making a diagnosis is visual in nature. Multimedia learning can promote constructivist learning, learning that occurs when learners seek to make sense of presented material by constructing a coherent mental representation (Mayer, 1999). The group presented with the video case study tended to spend more time discussing what happened in the video and presenting explanations for the patient’s condition. The research suggested that cognitive processes were stimulated by the inclusion of videos.

The third study ran a similar experiment using college students enrolled in an accounting course. The experimental group that received video in this study also scored significantly higher than those in the control group. However this experiment used controls in the form of a survey/questionnaire given to students before the experiment. It cited no significant differences in learning styles, preparation, or prior knowledge, between the two groups. This bolsters the idea that it is in fact video that is responsible for the difference.

The final study is different from the first two in that it does not compare groups who use video to groups who do not; instead it compares video based instruction to simulation based instruction, in an attempt to ascertain the educational outcomes of simulation based instruction. The study found that while both groups improved significantly from pretest to posttest, there was no difference in scores for students receiving video and those receiving simulations. While the main point of the study seems to illustrate the shortcoming of simulations, it also reveals the advantages of video based instruction.

Boster, F.J., Meyer, G.S., Roberto, A.J., Inge, C., and Strom, R. (2006). Some effects of video streaming on educational achievement. Communication Education, 55(1), 46-62.

Note: Video streaming refers to viewing video over the Internet – usually it is downloaded and viewed simultaneously. The articles goes on to mention several benefits of streaming.

The participants included 3 rd and 8 th grade students from three school districts in the southeastern part of the US. A total of 913 students and 38 teachers from 13 schools were in the 3 rd grade science/social studies study. 558 students and 8 teachers from 4 schools were in the 8 th grade science study, and 536 students and 7 teachers from 4 schools were in the 8 th grade social studies study. The schools were primarily rural.

Many studies showing that using communication technology in the classroom may increase learning must be viewed with caution because many of these studies did not follow a strict experimental design. This study used a pre-test/post-test, control group design to determine if video (streaming) supported the reported effectiveness of using video in a classroom presentation. The current available literature suggests that using communication technology (streaming video) will assist in 3 ways:

  1. enhance student attention and thus improve academic achievement.
  2. help prepare teachers to be more effective in the classroom.
  3. video streaming may change the nature of classroom interaction in ways that facilitate learning.

In the Discussion section of the report, the authors report that the results of the 4 experiments provide additional evidence that video streaming MAY contribute on average to increased student learning. They report that the experimental group student’s improvement on achievement tests exceeded the control group student’s improvement by 12.6%. The authors caution that understanding the precise reasons for the observed effects requires additional controlled trials coupled with increased data collection.

Participants in the study were medical school students at the University of Toronto. 144 students participated in the experiment, with group breakdowns as follows.

Scenario 1- n = 43

Scenario 2- n = 48

Scenario 3- n = 53

The research seeks to compare the affects and results of video based education against simulation based education, in medical school training for final year med students. The use of simulator technology has serious organizational implications for universities because of the cost, and management that are required. To evaluate the educational outcomes of simulation based education it was compared to video based education. Research based around three scenarios covering different medical school topics.

While scores for each group improved significantly from pretest to posttest there was no significant difference in score between those who received video based education and those who received simulation based education. In the first scenario, students receiving video based instruction actually had a greater rate of improvement from pre to posttest, though the difference was statistically insignificant.

Paediatric residents at Arhus University Hospital in Skejby, Denmark.

To investigate whether adding a brief video case instead of an equivalent written text improves the cognitive and metacognitive processes of residents in problem-based learning.

The authors of this study hypothesized that adding a video case (instead of reading about a case study, the patient and doctor interaction was presented in video format) would lead to a greater increase in data exploration and theory building and evaluation (they would spend more time searching for clues and proposing possible explanations for the patient’s condition.) This proved to be true with the video group. They tended to spend more time discussing what happened in the video and presenting explanations for the patient’s condition. The research suggested that cognitive processes were stimulated by the video.

Evening, n=25

Spring Semester
Day, n=27
Evening, n=33

This research is seeking to evaluate the effects of experiential learning on an accounting class. The body is moved by three considerations: development of pedagogical methods, learning styles, and measurement of instructional effectiveness. The experimental group received instruction from videotapes designed to give them, a feel for what actually happens in an audit, in addition to traditional lectures. The control group received only the lectures.

The study found that students in the experimental group scored significantly higher than those in the control group. Students were found to have no preexisting differences that relate to the experiment.


Is video helpful in language classes?

Video: Is video helpful in language classes?

Summary:

Based on the following articles, the research findings are positive in terms of the advantages of video in language classes. Video helps in the learning and retention of content and vocabulary in language classes. Video is viewed as the aiding tool for learners to better acquire listening, speaking, and pronunciation skills. Video is useful to orient learners with new units for the purpose of integrating prior knowledge with new materials. Video assists in recalling language learning through visual and contextual features. Furthermore, video with subtitles improves linguistic retention of learners.

Baltova, I. (1999). Multisensory language teaching in a multidimensional curriculum: The use of authentic bimodal video in core French. The Canadian Modern Language Review, 56(1), 31-48.

93 Grade 11 core French students. Their native language was English.

Students were divided into three groups. They all watched a science video. The first group watched it in reversed condition (English audio, French subtitles). The second group watched the video in bimodal condition (French audio, French subtitles). The third group watched the video in traditional format (French audio, no subtitles).

The purpose of the study was to find out how the learning and retention of content and vocabulary in French were affected by different authentic video formats.

  • Retention of the video content was superior under the subtitled conditions. However, there were no significant differences between the bimodal and reversed formats. Vocabulary retention in the bimodal group was found to be significantly higher than that in the reversed and traditional groups. No significant differences were found between the reversed and traditional groups.
  • With bimodal video students are exposed to real language, spoken at normal speed. They have advantage of subtitles that serve as linguistic help when the audio is too fast or too difficult to understand. The subtitles can be added to the video using one of bimodal programs. Other choice are authentic videotaped TV shows that have been closed captioned for the hearing impaired.

3 groups with 46 students each. Grades 4 and 5, Memnagar Primary School, Ahmedabad, India.

One group watched five subtitled Hindi film songs. The subtitles were in Hindi. The group two watched the same five Hindi songs, but without subtitles. The control group did not watch songs. Students had three sessions weekly over a three-month period.

The purpose of the study was to find out if watching same language subtitled songs on TV can improve reading skills of neo-literates in India. The improvement was measured by a pre-test vs. post-test difference at the syllable level.

  • The improvement of the Subtitle group was the highest, followed by the Without subtitles group and lastly the Control group. The experiment showed that reading skills can improve, at least initially, simply from exposure to the language. However, a rapid improvement was showed after students watched songs subtitled in the same language.
  • The experiment became a reality in Gujarat, India. Adult learners also showed measurable improvement in reading skills after watching subtitled songs. The experiment shows that same language subtitling makes reading practice incidental, automatic and sub-conscious.

White, C, Easton, P. & Anderson, C. (2000). Students’ Perceived Value of Video in a Multimedia Language Course. Education Media International, 37(3), 167-175.

26 students of Spanish enrolled in the first semester of a distance learning programme.

The purpose of this study is to investigate the following questions:

  • Question 1: How do students use the video component of a language course?
  • Question 2: What are student conceptions about the contribution of video sources to language learning?
  • Question 3: What kinds of affective evaluations are ascribed to video vs. print sources for language learning?
  • In regard to question 1, the study indicated that video was most commonly used to orient students to the new unit and to gain background into which subsequent material can be integrated.
  • In responding to question 2, the study explained that video was perceived as aiding the acquisition of listening and speaking skills, and pronunciation. The study also indicated that vidieo assist in recalling of the language by means of the visual settings and contextual features.
  • Regarding to question 3, the result revealed that affective evaluations of video sources are reflected with high enjoyment, low anxiety, and better mental efforts in language learning.

Murali Raman, Terry Ryan & Lorne Olfman. (2005). Designing Knowledge Management Systems for Teaching and Learning with Wiki Technology.

Journal of Information Systems Education, 16 (3), 311.

  Twenty students (three females and seventeen males, all majors in either information science or management) met in class for three hours per week over a sixteen-week period.

The goal was to enable students to learn about managing the design, development and operation of information technologies for knowledge management. During the semester, students were expected to create, refine, and maintain a knowledge management system, using an instantiation of wiki technology called TikiWiki.

The findings suggest that effective implementation and use of a wiki to support knowledge management for effective teaching and learning is contingent upon familiarity of both students and instructors with the technology, level of planning involved prior to system implementation and use in class, class size, and the ability to motivate students to learn from one another based on the principles of discovery learning.

Wikitextbooks are textbooks which are written using wiki technology.

The need to develop a wikitextbook arose in the context of the teaching of an introductory information systems (IS) course in Israeli Universities.

The proposal was to publish the outdated e-textbook as a wiki, and to invite students and the public to update the outdated textbook.

Each student will work on improving small fragments of the textbook as a part of their learning assignments.

In some classes, the students received credit for updating the wiki, and in other classes updating the wiki was an elective assignment.

The software chosen for the wiki was MediaWiki which allows users to write in any language.

The wiki assignment required students to read and augment existing sub-chapters in the wikitextbook, as well as to create new sub-chapters.

It was assumed that the process of contributing to such a textbook will be an empowering learning experience for the students, and a contribution to the academic institutions, to the discipline and to educators in academia and beyond.

In the period between May 2005 and November 2007, 7894 user edits were carried out on the wikitextbook.

389 sub-chapters were added by the users to the initial 225 sub-chapters, resulting in a total of 564 sub-chapters.

Ninety one images

were added by the users to the initial 172 images.

The students reflected positively over the experience.

The users described how the assignments forced them to explore a topic in more depth than otherwise.

Some students reported that they did not learn anything from the experience since they only wrote what they already knew.

Some students reported that the exercise exposed them to new knowledge while others felt like no new learning took place.

Students described their experiences not only as enjoyable and educational but also specifically as an empowering exercise.

The experience provides a glimpse into the potential of wikitextbooks to become vehicles for the empowerment of students, teachers, and classes, and for the strengthening of educational institutions, disciplines, minorities, and society in general.

The wiki is a participatory medium and students are empowered by their participation in the educational process.

Wikis may also contribute to society if and when they are made freely available online.

Limitations

Issues such as perceptions, attitudes towards technology, and social influence can augment or diminish the usefulness of the technology.

Empowerment is also a relative concept; the empowerment of one stakeholder could potentially weaken another stakeholder.

Differential empowerment, a process by which stronger members are disproportionately empowered, thus increasing the gap rather than narrowing it.

The preliminary and exploratory field study was performed without controlling for independent variables.

Solvie, P.A. (2008).Use of the wiki: Preservice teachers' construction of knowledge in reading methods courses. Journal of Literacy and Technology. 9(2), 57-87.

18 preservice teachers

1. Did learning style preference have an effect on use of the wiki?

2. Did use of the wiki increase understanding of the social nature of literacy?

3. Did use of the wiki increase understanding of reading instructional practices for students with various learning style preferences?

4. Did use of the wiki support students’ ability to construct knowledge in the context of the reading methods course?

1. The wiki addressed all four learning preferences but results showed that not just the wiki as a whole needed to be aligned with learner style preferences but the specific tasks within the wiki.

2. This research found that the students did not connect this wiki experience to reading instructional practices on their own.

3. Participants narrative comments did not vary according to learning style preference.

4. Participants responses indicated they learned about reading instructional approaches from the wiki project.

Four groups of students in the college of education aged 18-25 (n = 35)

To determine the usefulness of wikis in fostering collaboration/support and promoting understanding among students

  • Students enjoyed the wikis but some found them to be a little unstructured.
  • Students contributed the wikis but only read the sections of the wiki to which they contributed.
  • Students took such ownership of their pages that they became emotional. At times they expressed that they would “cry” or become very angry if their contributions were altered in any way.
  • Contributions can become unbalanced with some students participating substantially more than others.
