Background: Digital simulations are emerging technologies in science education that allow students to visualise abstract concepts and enable science teachers to conduct laboratory work/experiments online. Objective: To determine teacher readiness, the study focused on their cognitive skills and knowledge and perceptions of the use of digital…

Compares collaborative problem solving by learners sitting side-by-side with computer-mediated learning at a distance. Three aspects are studied: high school students' problem- solving strategies and interpretation of the teaching situation; their use of components of the situation; and the cognitive processes involved in understanding domain…

Describes software that was designed in the United Kingdom to promote conceptual change in secondary school students studying mechanics. Direct Manipulation of Mechanical Microworlds, an interactive computer simulation, and VARILAB, a computer-based language for modelling systems, are explained; and two studies that will evaluate the effectiveness…
