Abstract Title: Regression analysis exploring teacher impact on student FCI post scores
Abstract: In this poster we present the results of a regression analysis exploring high school teacher impacts on student Force Concept Inventory (FCI) scores. The data was collected from 1,344 students of 18 high school physics teachers. In this analysis we utilized the teacher, FCI Pre Score, Gender, and Ethnic Representation as the independent variables and FCI Post Score as the dependent variable. The regression analysis returned an effect size of .37 (Cohen's f2) and indicated that 12 out of 18 high school physics teachers had a significant impact in accounting for the variance within student FCI Post Scores. Further analysis showed that of the 12 teachers accounting for a significant amount of the variance, only five had a positive beta coefficient.  This indicates that there are dynamic differences between teachers that may be revealed through other measures such as the Reformed Teaching Observation Protocol (RTOP).
