The Contribution of Certain Science Investigations to the Understanding of the Elements of Scientific Model Building by General Science Students Enrolled in a Three-Track Curriculum.
The purpose of this study was (1) to develop a specific series of instructional materials which promote the concept of models, (2) to determine if there were significant differences between the apparent ability of students as indicated by their placement in various tracks and their ability to understand the elements of model building, and (3) to determine if there were significant differences in understanding models when the order of presentation is altered. Three units of materials were used which varied in their content-process orientation. The study involved 1,000 eighth grade general science students, 36 classes and eight teachers. The students were divided into two groups of equal numbers based on track designation. The science investigations were presented in two different orders, and each group received a pre-, intermediate, and post-test. Significant gains in the understanding of the elements of model building were noted between the pre- and post-tests on both groups, but there was no significant difference in gains between the two orders of unit presentation. Evidence was insufficient to support a decision as to which track benefited most from the study. (GR)
