This project is designed to generate evidence that is descriptive [observational] and associative and/or correlational [interpretive commentary]. Original data is collected from teachers across the professional continuum using observation [personal observation and videography] and survey research [semi-structured or informal interviews]. The project also involves the analysis of existing video archives of teaching.
Three research teams share data sources, utilize similar methods, and when synergistic, engage in joint analyses. Although the foci and analytic lenses used by each team differ, each team engages in the following three main types of work: (1) analyzing records of classroom practice; (2) analyzing and developing measures of MKT; and (3) engaging multidisciplinary experts in the work. Drawing on an interactive model of instruction (Cohen, Raudenbush, & Ball, 2003), to analyze MKT we first articulate the work of teaching and then analyze its mathematical demands (Ball & Bass, 2003; Thames, 2009). To validate our measures, we use cognitive interviews.
