There is consensus around the fact that quality of teaching is one of the most important school-level factors to influence student achievement at school. Evidence from research suggests that better-qualified teachers can be the determining factor for student achievement and development (Jordan et al., 1997; Sanders & Rivers, 1996; Wright et al., 1997). Therefore, policy makers advocate for ongoing improvements in teacher quality variables, in which the implementation of a well-designed teacher evaluation system has been found to be one of the most effective ways to improve teacher quality (Darling-Hammond, 2010; Looney, 2011; Rockoff & Speroni, 2011). The case of Chile is a particularly interesting example of a teacher evaluation system since its implementation, a validation process that has included not only the experience and documentation regarding the process, but also a comprehensive agenda regarding the validity and reliability of the instrument and evaluation consequences (Taut & Sun, 2014).
The purpose of this dissertation is to contribute to the body of research on the evidence of the validity of Chilean teacher evaluation. Specifically, I focus on one of the teacher evaluation instruments: the portfolio. Through the portfolio, teachers provide evidence of their best practices in three modules: a set of pedagogical materials, video recording class, and collaborative work (not mandatory).
In order to accomplish this goal, I use the data from the portfolio results of the 2017 Chilean National Teacher Evaluation (N = 21,982). I use descriptive statistics, exploratory confirmatory factor analysis (ECFA), and factorial invariance to assess the structure of the portfolio across different teacher subgroups: teachers with and without the collaborative work module score, rural/urban teachers, and six different teaching levels. I also compare the theoretical weight assigned to each one of the portfolio indicators with the empirical data. Finally, I evaluate if the (open full item for complete abstract)
