Peer reviewed Peer reviewed
Nachmias, Rafi; Linn, Marcia C. – Journal of Research in Science Teaching, 1987
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…

Cognitive Consequences of Student Estimation on Linear and Logarithmic Scales.
Peer reviewed Peer reviewed
Berger, Carl F.; And Others – Journal of Research in Science Teaching, 1987
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…
