This paper is an invited adaptation of the IEEE Education Society Distinguished Lecture Approaches to Interactive Video Anchors in Problem-Based Science Learning. Interactive video anchors have a cognitive theory base, and they help to enlarge the context of learning with information-rich real-world situations. Carefully selected movie clips and…

Synthesizes the results of three case studies of middle school classrooms in which computer and video materials were used to teach topics in earth and space sciences through interactive simulations. Describes specific instances in which common current practice is problematic. Makes suggestions regarding improved design principles for such…

Explorer is an interactive environment based on a constructivist epistemology of learning that integrates animated computer models with analytic capabilities for learning science. The system includes graphs, a spreadsheet, scripting, and interactive tools. Two examples involving the dynamics of colliding objects and electric circuits illustrate…
