Abstract Title: The Electron Gas Model: Empirical Results of a Diagnostic Assessment
Abstract: Effective reasoning about electric circuits requires a solid understanding of voltage and potential. However, most students fail to correctly analyze electric circuits as they tend to reason exclusively with current and resistance. In order to address these difficulties, a new teaching concept based on the electron gas model was developed and empirically evaluated in a study with 790 students from Frankfurt, Germany. The study followed a pretest-posttest-control-group-design and used a recognized two-tier diagnostic test instrument, which also allowed evaluating common alternative conceptions. The results of the diagnostic assessment are very promising: Students taught according to the new teaching concept do not only develop a significantly better conceptual understanding, but also show achievement gains more than twice that of their traditionally taught peers. The presented poster will report in more detail on the key findings of the multiple-choice diagnostic assessment as well as the empirical methods used in the study.
