Describes a study of undergraduates that compared navigational study strategies, the extent of lesson coverage, and attitudes about learning with three types of hypermedia lessons to examine how learners use different types of graphical browsers in...
Effects on Children's Achievement and Curiosity of Variations in Learner Control over an Interactive Video Lesson
Educational Technology Research and Development Vol. 40, No. 1 (1992) pp. 15–27
The effects of variations in learner control were examined for an interactive lesson presented as a videodisc visit to an art museum. The 101 first and second grade subjects were assigned to program control, learner control, and learner control with ...
Stimulating Intrinsic Motivation for Problem Solving Using Goal-Oriented Contexts and Peer Group Composition
Educational Technology Research and Development Vol. 54, No. 5 (October 2006) pp. 445–466
One important factor related to ill-structured problem-solving success is intrinsic motivation, that is, students' willingness to persist in solving the problem. Goal orientation, a motivational variable, explains reasons why students engage in the...
Interactive Video and Cognitive Structures: A Technique for Enhancing the Effectiveness of Interactive Simulations and Games
In the late 1960s and early 1970s a considerable amount of research was conducted on methods for authoring and structuring instructional materials by researchers who did not, at that time, have access to the existing delivery systems necessary to...
