The purpose of the two experiments was to investigate the potential effects of different types of visualizations and self-explanation prompts on learning human cardiovascular system in a multimedia environment. In Experiments 1 and 2, 70 and 44 college students were randomly assigned to one of the four conditions in a 2 × 2 factorial design with…

Video usage in educational contexts is on the rise. We examined 3 alternative theories about cognitive mechanisms of learning and their implications for instructional design when video is employed to enhance text-based learning. Hypothesis-testing procedures followed a falsificationist approach, grounded in philosophy of science literature.…

Presents a meta-analysis of research concerning the effectiveness of learner control in tutorial computer-assisted instruction based on a model of control as decision making plus information. Results are discussed which suggest that instructional design in learner control research should be based on model building rather than hypothesis testing.…

Discussion of the teaching of learning strategies focuses on a study of undergraduates that investigated the effects of comprehension-directed and memory-directed computer-based learning strategy training on the achievement of learning objectives. Treatment of experimental and control groups is explained, and further research is suggested.…

Discussion of appropriate feedback in an instructional setting focuses on a study of undergraduates learning graphics materials production techniques that investigated whether internal feedback, provided by an expert system, differed in effectiveness from external feedback, provided by an instructor. The effects of each on processing activities…

Describes aptitude treatment interaction study that used the cognitive styles field dependence and independence matched with computerized algorithmic and discovery treatments to determine mathematics achievement on a criterion-referenced test. Posttest mathematics scores and student responses to the computer are analyzed, and mastery learning is…

Describes a study that examined increasing peer interaction in an asynchronous learning environment by investigating the effect of a teacher's discourse style on the level and quality of student participation in a computer-mediated discussion. Three discourse styles (i.e., questions, statements, and conversational) are studied, and further…

Discusses strategies for teaching elementary computer programing and describes a study that used two instructional strategies in a computer-based training program designed to teach turtle graphics programing techniques to novice undergraduate students. Learning activities that emphasized either the completion of existing programs or the generation…
