A confirmatory factor analysis of EQIPM, a video coding protocol to assess the quality of community college algebra instruction
Page: 415
Evaluating the Quality of Instruction in Post-secondary Mathematics (EQIPM) is a video coding instrument that provides indicators of the quality of instruction in community college algebra. Following an extensive revision, and the coding of a set of 84 videos from 40 instructors, we report the results of a confirmatory factor analysis, that suggests that the instrument captures three distinct hypothesized dimensions of quality of instruction in community college algebra classes. Due to the nature of the instruction observed, the items in the instrument needed to be treated as categorical and some had to be removed from the analysis. We use the data to provide a first glimpse of the quality of algebra instruction that we found in this data set.
