Direct linkFrailich, Marcel; Kesner, Miri; Hofstein, Avi – Journal of Research in Science Teaching, 2009
This study investigated the effectiveness of a web-based learning environment in enhancing 10th grade high-school students' understanding of the concept of "chemical bonding". Two groups participated in this study: an experimental group (N = 161) and a comparison one (N = 93). The teachers in the experimental group were asked to implement four…

Peer reviewedFarynaiarz, Joseph V.; Lockwood, Linda G. – Journal of Research in Science Teaching, 1992
Utilizes a quasiexperimental design to examine the impact of microcomputer simulations on environmental problem solving by community college students. The experimental group of students (n=34) showed a highly significant improvement in problem-solving skills after being exposed to three simulation models that focused on lake pollution analysis,…

Peer reviewedPizzini, Edward L.; Shepardson, Daniel P. – Journal of Research in Science Teaching, 1992
Compares models of the classroom dynamics for a traditional laboratory setting and a problem-solving-centered environment, both at the eighth grade science level. Descriptive data indicate no differences in the models, whereas path analyses suggest that, in the problem-solving model, student behaviors significantly correlate to lesson structure,…
