Summary.-The hypothetical construct of cognitive structure encodes human knowl- edge internally, and two-stage probes are used to define it operationally to obtain ex- ternal representations of cognitive structure. First, a proximity matrix is constructed that encodes subjects' responses on a task, and secondly, a scaling method is applied to the proximity matrix to yield a representation of cognitive structure in the form of concept categories or spatial configurations. A new multitechnique-mdt...

This study investigates the hypothesis that when children are engaged in science experiments, the goal of which is to understand relations among causes and effects, they often use the engineering model of experimentation, characterized by the more familiar goal of manipulating variables to produce a desired outcome. Sixteen fifth- and sixth-graders worked on two experimentation problems consistent with the engineering and science models, respectively. The context in which these problems were fra...

The utilization of cognitive psychological theory and findings from research to inform the design of instruction is illustrated in this paper. Physics learning studies demonstrate that students' pre‐instructional world knowledge is often logically antagonistic to the principles of Newtonian mechanics taught in introductory physics. Under these conditions psychological theory predicts that learning will be inhibited, a prediction consistent with both the experiences of physics teachers and the re...

To explain students' achievement in the mechanics segment of a college physics course, a causal model is proposed whose variables are the three constructs: Newtonian physics, math ability, and science experience. Each variable specifies several variates, whose numerical values were measured and intercorrelations computed. The Factorial Modeling (FaM) procedure is applied to the data to estimate the coefficients of the proposed model's structural equations. The FaM results indicate that the model...
