Instrumentation, methodology, and analysis techniques were developed to measure changes in adolescents' (N=10) skills in linear distance estimation. Microcomputers were used to present and control amount of information available to assist students in said estimations. Results and implications are reported. (Author/SK)

Evaluates the attributes of a microcomputer software package as a supplement to chemistry instruction. Reports higher scores among the students in a control group. Discovers no significant interaction between treatment and development stage. Discusses several implications for further research. Provides the General Chemistry Test and error analysis…

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)

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…

Examines students' problem solving performance on linear and logarithmic estimation tasks using a microcomputer. Results are discussed in terms of performance data and strategy used. Students were able to estimate faster and more efficiently for the linear estimation task but experienced difficulty on a logarithmic scale. Discusses reasons for the…

Discusses the benefits of five short science courses offered to middle school age children and their parents. Reports on the participants' reactions, two to three years after taking the courses, to the course experiences, the influence of the courses on learning behavior, and the relationship between the parents and their children.
