Presents data indicating that learning can be enhanced when information is presented that illustrates how science information can be used to solve problems. The experiments showed positive results through use of video-based macro-contexts. (ML)

When comparing performances across four versions of Computer as Lab Partner curriculum, increases in understanding were found when students predicted outcomes and reconciled results, and students used a heat-flow model of thermodynamics to integrate their experimental results. Argued is that curriculum must explicitly motivate students to…

Examines (1) how students evaluate information obtained in the science laboratory; (2) the effects of use of microcomputer-based laboratory; and, (3) the effects of explicit instruction on critical evaluation skills. Discusses results in terms of students' propensity to accept incorrect graphs and in terms of the effect of the enhanced instruction…

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,…

Reports on a study that investigated the effects of various instructional practices on programming proficiency focusing on characteristics of Pascal classes. States that instructional practices involve extensive on-line access, explicit instruction, and extensive feedback. (ML)
