The evaluation of teachers' subject knowledge is an essential part of teacher evaluation. The evaluation methods represented by classroom observation, task-based interview and standardized tests have some problems, such as fragmented evaluation of knowledge, poor reflecting of internal knowledge structure. This study aims to explore the applicability of using concept mapping to evaluate teachers' subject knowledge. Fifty-seven mathematics teachers from 3 primary schools participated in this study, and their knowledge is evaluated through three types of concept mapping tasks (Fill-in-concept map, Concept mapping based on list of concepts, and Concept mapping based on a focus question). The study finds that: (1) concept mapping is an effective way of evaluating the subject knowledge of primary mathematics teachers. The results show that primary mathematics teachers have problems such as insufficient subject ontology knowledge, serious fragmentation of knowledge, and unreasonable knowledge structure. (2) Compared to "filling-in concept map" and " Concept mapping based on list of concepts ", " Concept mapping based on a focus question " is more accurate and more sensitive in evaluating teachers' subject knowledge.
