In the current study, we aimed to develop a reliable and valid scale to address individual cognitive load types. Existing scale development studies involved limited number of items without adequate convergent, discriminant and criterion validity checks. Through a multistep correlational study, we proposed a three-factor scale with 13 items to…

Tasks provide engaging ways to involve learners in meaningful, real-world activities with the foreign language (FL). Yet selecting classroom tasks suitable to learners' linguistic readiness is challenging, and task-based research is exploring the relationship between learners' overall abilities (e.g., reading, grammatical) and the complexity and…

This study investigated the effects of a pedagogical agent that cued relevant information in a story-based instructional animation on the cardiovascular system. Based on cognitive load theory, it was expected that the experimental condition with the pedagogical agent would facilitate students to distinguish between relevant and irrelevant…

To foster medical students' diagnostic knowledge a case-based worked example approach was implemented in the context of a computer-based learning environment. Thirty medical students were randomly assigned to the condition "with erroneous examples", and 31 students learned with correct examples. Diagnostic knowledge was operationalised…

The objective of this study is to identify some of the structural features of an elementary logic curriculum which affect logic problem difficulty. The system under review is a computer-based logic instructional system (LIS) at Stanford University. Four modes of problem presentation--multiple-choice, truth-analysis, counterexample, and derive--are…

An application of the two-paramenter logistic (Rasch) model to tailored testing is presented. The model is discussed along with the maximum likelihood estimation of the ability parameters given the response pattern and easiness parameter estimates for the items. The technique has been programmed for use with an interactive computer terminal. Use…

This report describes courseware for comprehensive computer-assisted testing and instruction. With this program, a personal computer can be used to: (1) generate multiple test versions to meet test objectives; (2) create study guides for self-directed learning; and (3) evaluate student and teacher performance. Numerous multiple-choice examples,…
