A Further Investigation to Introducing the Equal Sign in China

Fostering students' bidirectional conception of the equal sign (viewing the equal sign as indicating an equivalence of two sides rather than a 'show result' symbol) is challenging, and students' misconception of the equal sign is persistent. Some studies mention that in China, the pedagogical approach to introducing the equal sign supports students' development of bidirectional sense toward the equal sign. Built up on this body of literature, this paper further investigates the Chinese pedagogy from the researcher, students and the teacher's perspectives.
