Student designs of experiments as indicators of physics reasoning

The purpose of this study was the assessment of physics reasoning on the basis of students' understanding of motion on an inclined plane. Subjects were presented with a video tape showing a motion experiment in steps and were asked to formulate hypotheses and design an experiment to test these. Subjects thought aloud while specifying the designs and goals of an experiment. Protocols were analyzed by an original method using schema representation techniques. Adequancy of subjects' reasoning was evaluated by comparison to a composite model built from physics domain principles. As more information was presented to subjects, processing differences were observed. Using a hierarchy of processes from recognition to generation, five groups of subjects were defined. Subjects differed in recognition and inclusion processes, use of incoming information, ability to generate experimental designs, and responses to falsification. Concepts of average velocity and differences in directionality of reasoning were analyzed.
