We investigated whether and how prior knowledge activation improves learning outcomes for high school (less experienced learners) and university students (experienced learners) in a hypertext environment. Map coherence was defined as the extent to which relationships between the concepts in the map were made explicit. Therefore, we classified the…

Discusses how students learn to model in scientific contexts. Highlights include current research in science education; a computer-based simulation of a student learning to model; an example of a physics task; collaboration with another student; a dialog mechanism; and external representations.

Examines relations between the features of discovery simulations, the learning processes elicited, the knowledge that results, and the methods used to measure the acquired knowledge. Discusses intuitive knowledge and describes a study of post-secondary students that investigated the instructional effectiveness of discovery simulations in physics.…
