Abstract electronics concepts are difficult to develop because the phenomena of interest cannot be readily observed. Visualisation skills support learning about electronics and can be applied at different levels of representation and understanding (observable, symbolic and abstract). Providing learners with opportunities to make transitions…

Describes a study of undergraduates that examined the potential trade-off in study efficiency and breadth of learning for hypertexts studied by selecting units from a content map. Compares study strategies and text recall with a more- and less-segmented hypertext and discusses text representations, study times, knowledge representation, and…

Computer-Supported Intentional Learning Environments (CSILE) is a database system in which learners collaboratively construct the knowledge represented in the database. This study examines how students in a grade-five and -six classroom built their database on a science topic, electricity. Differences in cognitive and operative activities between…
