Two focusing hypotheses were evaluated. First, do adjunct questions, focusing on science concepts and inserted after computer-animated sequences, selectively alter students' attentional processing and thus produce differential learning effects? Second, to these questions still provide enough metacognitive scaffolding to produce differential…

Reports on a study designed to investigate how the use of computer assisted instruction (CAI) tutorial programs, incorporating advance organizers and involving various sizes of groups of subjects, would affect achievement scores, retention scores, and rates of learning. (TW)

Presents perspectives on creating new technology-based supports for science learning. Reviews current philosophies concerning the interpretative nature of scientific inquiry and discusses the difficulties of students and teachers in science education. Describes a prototype software system for supporting scientific inquiry processes in students.…

Defines artificial intelligence (AI) in relation to intelligent computer-assisted instruction (ICAI) and science education. Provides a brief background of AI work, examples of expert systems, examples of ICAI work, and addresses problems facing AI workers that have implications for science education. Proposes a revised model of the Karplus/Renner…

Discusses a study which assessed the effect of a brief kinematics unit on: (1) students' ability to translate between a physical event and the graphic representation of it, and; (2) the effect of real-time on graphing skills. Reports the success of the use of a microcomputer-based laboratory with graphing velocity and distance. (ML)
