Effects of Training on the Concepts of Water Level and Horizontality in the Classroom.
Weinstein, Melissa Starbuck
This experiment was designed to see if classroom instruction in the concept of water level and horizontality can improve students' knowledge of these concepts. The sample consisted of a kindergarten and a second grade class from one school and a first grade class from another school. Each class was divided into three groups. The first group was given three 20-minute training sessions, the same for each grade. The second group was given a similar treatment in which the words "horizontal" and "vertical" were used and stressed. The third group was a control. All nine groups were given the same test of 16 experimenter-designed, diagram-completion items before and after treatments. The pretest showed substantial differences between the nine groups, so treatment effects were first analyzed by a rank order test on group means. The data supported the prediction that experimental groups would perform better than control groups, but detected no difference between the two versions of the experimental treatment. Three multivariate analyses of variance were also performed in an attempt to eliminate the effect of initial group differences. (MM)
