The study involved the development, implementation and evaluation of laboratory audio-tutorial activities in a college chemistry course. The activities were designed in a self-instructional mode, written as linear programs and taped instructions. A pretest was used in two instances, but all included a posttest. To evaluate the effectiveness of the…

This study investigated the feasibility of using computer-simulated experiments in high school physics and chemistry. Fifteen sections of students enrolled in high school physics and chemistry were randomly divided into experimental and control groups. A series of 10 experiments was done by use of computer simulation in the experimental group;…
