Item Application of STEM Web cooperative learning for the senior high school students.(2009-10-15) Liu, Y.-H.; Lou, S.-J.; Shih, R.-C.; Tseng, K.-H.; Chang, C.-C.; Diez, C.-RItem Students' learning satisfaction and progress toward nanometer course employing concept mapping learning Web platform.(2009-06-17) Tseng, K.-H.; Chang, C.-C.; Chao. M.-W.; Tai, W.-S., Huang, Y.-M.Item An empirical case study on the relationship between participation in online discussion and achievement of project-based work(Hauppauge, NY: Nova Science Publisher., 2008-11-01) Chang, C.-C.Item Using a Web-based portfolio assessment system to elevate project-based learning performances.(2011-01-01) Chang, C.-C.; Tseng, K.-H.This study examines the effect of a Web-based portfolio assessment system on the performances of students undertaking project-based learning (PBL). The research targets were 60 students from two grade-8 classes taking senior high school computer courses. The experimental group comprised 30 students, who used the system to perform PBL and assessment in one class. The control group comprised of 30 students who employed conventional assessment for PBL of another class. Experimental results indicate that the system has no significant effect on student achievement, but had a statistically positive effect on self-perceived learning performances. In addition, teacher-assessment and self-assessment of project achievements produced different results.Item Using jigsaw collaborative learning strategy in online discussion to foster a project-based learning community on the web.(2009-08-01) Chang, C.-C.This article mainly describes the use of jigsaw collaborative learning strategy in online discussion to foster the form of an online learning community, called Web-enabled Project-Based Learning Community. Moreover, this article also discusses the concepts of Project-Based and Web-enabled PBL Community, importance of online discussion in community, and jigsaw collaborative learning method. Finally, implications and conclusions are proposed. Keywords: Jigsaw Collaborative Learning, Online Discussion, Project-Based Learning, Learning CommunityItem Applications of cognitive load theory to multimedia-based foreign language learning: An overview.(2009-02-01) Chen, I.-J.; Chang, C.-C.; Lee, Y.-C.Item Self-evaluated effects of Web-Base portfolio assessment for various student motivation levels.(2009-11-01) Chang, C.-C.Item Use and performances of web-based portfolio assessment.(2009-03-01) Chang, C.-C.; Tseng, K.-H.This research explored the influence of a Web-based portfolio assessment system on students' performances. The methodological procedure adopted was to have the experimental group use the system, with the control group using conventional assessment. The study subjects were junior high school students of two computer classes. The experimental results revealed that the use of the system has significant positive influence on students' performances. According to estimated effect size, the most significant indicators were reflection, self-assessment, continuous improvement, goal setting, problem solving, data gathering, work and peer interaction. However, peer-assessment performance was not enhanced significantly. Therefore, one recommendation was to reduce peer-assessment and instead offer specific illustrations to the students as well as the opportunity to drill.Item Cognitive load theory: An empirical study of anxiety and task performance in language learning.(2009-09-01) Chang, I. J.; Chang, C.-C.Introduction: This study explores the relationship among three variables--cognitive load, foreign language anxiety, and task performance. Cognitive load refers to the load imposed on working memory while performing a particular task. The authors hypothesized that anxiety consumes the resources of working memory, leaving less capacity for cognitive activities, and impeding effectiveness. Method: The participants were 88 non-English major students enrolled in a 4-year program at a technical university in Taiwan. The Foreign Language Classroom Anxiety Scale was employed to examine their anxiety levels; the Cognitive Load Subject Rating Scale was utilized to measure their cognitive load while engaging in an English listening comprehension task. Results: The students with higher foreign language anxiety also incurred a higher cognitive load. Foreign language anxiety and cognitive load were in negative correlation with listening comprehension. Discussion: Learners who experience more anxiety incur a heavier cognitive load and receive lower test scores. To enhance learning effectiveness, instructors are encouraged to identify anxiety-provoking situations and provide a supportive learning environment so that the learners can devote their complete working memory resources to the learning tasks.

For teaching and learning purposes, e-portfolios have been used at a growing number of education institutions. This article reviews four important issues regarding e-portfolio use in the field of education: benefits, adoption concerns, development model, and pedagogical issues. Potential problems, such as the lack of empirical studies, are identified.
