It is often hypothesized that prior knowledge strongly predicts learning performance. It can affect learning positively mediated through some processes and negatively mediated through others. We examined the relation between prior knowledge and learning in a meta-analysis of 8776 effect sizes. The stability of individual differences, that is, the…

Feedback is one of the most important factors for successful learning. Contemporary computer-based learning and testing environments allow the implementation of automated feedback in a simple and efficient manner. Previous meta-analyses suggest that different types of feedback are not equally effective. This heterogeneity might depend on learner…

The main purpose of this study was to investigate the effect of the holistic approach, as compared to the segregated-skill approach, on the quantity and quality of EFL students' academic writing. The subjects for the study were 64 graduates enrolled in the Special Diploma in Education at the School of Education in Suez during the second semester…

Describes a study that investigated the effects of learner control and of advisement in a hypertext learning environment with second-grade students who had different levels of prior knowledge about the content. Topics discussed include computer-assisted instruction; learner control; and recommendations for instructional design in a hypertext…

Describes a study of Korean elementary school students that was conducted to investigate the effects of differing types of instructional control strategies and cognitive style on achievement in arithmetic skills using computer-assisted instruction. Hypotheses tested are discussed, time on task is investigated, and future research is suggested.…

Maps or graphical browsers of structural knowledge allow the user of a hypertext system to navigate from node to node through the structure as they portray the links between concepts spatially. This study examined the results of using two different graphical browsers that provide different amounts of information about the structure of the…

Describes a study that examined the extent to which different levels of instructional control and varied learner characteristics affected performance and time on task, using interactive video in a college biochemistry course. Prior knowledge and learner internality/externality are discussed, and interaction between learner ability and…

Describes a study that investigated statistical factors associated with teachers' telecomputing use during a graduate telecommunications course. Variables including age, teaching experience, telecommunications experience, computer anxiety level, and writing apprehension level were examined for relationships with login frequency. Implications for…
