CHAPTER 4
TESTING A HISTORICAL CONTEXTUALIZATION OBSERVATION INSTRUMENT
This chapter describes the development and testing of the Framework for Analyzing the Teaching of Historical Contextualization (FAT-HC). This high-inference observation instrument focuses on history teachers’ competency in promoting historical contextualization in classrooms. Generalizability studies were conducted to assess the instrument’s dimensionality and reliability by decomposing the instrument’s variance. A large proportion of the variance was explained by differences between observed teachers, and a small proportion of the variance was explained by lessons and observers, demonstrating the instrument’s reliability. Furthermore, a decision study was conducted to determine the optimal number of observers and lessons needed for a reliable scoring design.
