ABSTRACT

Chinese elementary teachers were found to possess a profound understanding of fundamental mathematics (PUFM) (Ma, 1999) and the teachers in Ma’s study reported that their PUFM was mainly attained through the intensive study of textbooks. Although textbooks have played a crucial role in Chinese school education to guide and structure classroom instruction (e.g., Li, Chen, & Kulm, 2009; Li, Zhang, & Ma, 2009), very few studies have explored how Chinese teachers study textbooks. Thus, much remains unclear about how the study of textbooks may help Chinese teachers gain knowledge and design classroom instruction. This chapter explores these issues through Chinese teachers’ knowledge and understanding of a seemingly trivial but actually important mathematical idea, “0 cannot be a divisor,” that has been commonly ignored by many U.S. teachers when teaching equivalent fractions. In particular, we aim to explore how the study of textbooks may have contributed to Chinese teachers’ understanding of this knowledge point. It is expected that this case study will reveal effective practices that Chinese teachers employ to acquire their PUFM through the study of textbooks.
