A Comparison of Two Methods of Managing Laboratory Experiments.
Egelston, Judy C.; Egelston, Richard L.
This study compared two groups of high school biology students with respect to laboratory achievement, learning climate, and laboratory behavior on the part of both students and teachers. A cell physiology and nutrition unit containing ten exercises was utilized by five randomly assigned teachers (86 students) in an open-inductive method and by four randomly assigned teachers (90 students) in the conventional method. All teachers were experienced, given a special training session, and volunteered to participate. The adjusted trend analysis revealed some evidence that, after several experiments using the inductive method, the hypothesized curvilinear trend in achievement scores of the open-inductive group was equally as good or better than for the scores of the control group. The laboratory behavior of the two groups was significantly different on five of six comparisons as identified by an interaction analysis system developed by the author. Learning climate, indicated by using an instrument designed to measure the socio-emotional properties of the learning environment, was significantly different between the two groups. (Author/PR)
