Microcomputer-based laboratories (MBL), the use of microcomputers for student-directed data acquisition and analysis, represents a promising new development in science laboratory instruction. This descriptive study determined the impact of MBLs on middle school students' understanding of graphs of distance and velocity. The study was based on the…

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…

Reports results of a study examining the effectiveness of microcomputers as aids in developing problem-solving skills. Group dynamics of students working with microcomputers was also explored, as well as the effectiveness of this instructional aid with students of varying abilities. (CS)

Examines the influence of two factors of the process of graphing on rural students' (n=93) ability to comprehend kinematics graphs on constant velocity events. Students exhibited difficulty in constructing and comprehending graphs of derived variables and were unaware of their own graphing skills deficiencies. (34 references) (MDH)

Problems ask students to calculate the pressure against a billboard in high winds and the velocity of water flowing from a reservoir through a cylindrical pipe. Problem solutions incorporate computer tools such as spreadsheets. (MDH)
