Building on earlier work that explored within-student variation in hours of instruction across school subjects, we investigate the impact of instruction time on student test scores in Switzerland, as measured by the PISA 2009 test. Our results confirm the results of previous studies of a positive effect of instruction time on student performance.…

After a decade of virtual learning environments (VLEs) in higher education, many teachers still use only a minimum of its affordances. This study looked at how academic staff interacted with a new and unknown VLE in order to understand how technology acceptance and support materials influence (perceived and actual) task performance. In an…

The purpose of this study was to examine the relationship between reflection performance and the learning effect with learners in a web-based portfolio assessment environment. The participants were 45 eighth graders randomly selected from computer classes at a middle school in Taiwan. The reflection performance in this study included frequency of…

This study expanded the definition of reading practices to include both print- and Internet-based reading, and examined the relationship of reading profiles to Taiwanese college students' performance on various practices.

A large body of research has shown that for novice learners, instruction that relies more heavily on worked examples than on problem solving, is more effective for learning as shown by higher test performance. Moreover, this beneficial effect is often obtained with less acquisition time and lower cognitive load during acquisition and test phase.…

Introduction: Computer Supported Cooperative Work (CSCW) projects are difficult to evaluate when implemented at most organizations. There are many variables and some of these are qualitative and hard to assess. However, there are other variables that could be measured and, thus, for a specific CSCW system, management could have a performance…
