Choi, Byung-Soon; Gennaro, Eugene – Journal of Research in Science Teaching, 1987
Reports on a study which compared the effectiveness of microcomputer simulated experiences with that of parallel, hands-on laboratory instruction for teaching the concept of volume displacement to junior high school students. Results indicated that computer simulated experience were as affective as hands-on laboratory experiences. (TW)
