This article uses data from 65 teachers participating in a K-2 mathematics professional development research project as an example of how to analyze video recordings of teachers' classroom lessons using mixed methods. Through their discussion, the authors demonstrate how using a mixed methods approach to classroom video analysis allows researchers to draw more comprehensive conclusions about participants both collectively and individually. Implications for using a mixed methods approach to analyze classroom video research are provided. (Contains 1 figure, 4 tables, and 2 notes.)
