摘要

This dissertation reports on an investigation of student understanding of kinematics and dynamics in the context of Galilean relativity. Through the administration of written questions and interviews with individual students we have assessed student ability to determine and relate quantities such as displacement, velocity, and momentum in multiple frames of reference. We have found that many students have difficulty applying systematic measurement procedures for such quantities in a frame of reference moving relative to the laboratory. A variety of specific conceptual and reasoning difficulties have been identified. Difficulties with more complicated concepts, such as relative velocity or acceleration, can be traced to difficulties with basic, underlying ideas, such as displacement. In addition, difficulties with relative motion can in some cases be traced to difficulties with concepts and reasoning associated with laboratory frame kinematics. Many of the difficulties that have been identified are prevalent both before and after traditional instruction, and are encountered by physics students at the introductory through the graduate level. Results of the investigation have been used to guide the design of curriculum in the introductory physics course and in special physics courses for prospective and practicing precollege teachers.
