Abstract: Conceptual change is a critical issue in psychological and educational fields. From different backgrounds and beliefs, Researchers have investigated conceptual change and given rise to several theories for interpreting the processes and mechanism of conceptual change in the past two decades, like epistemology, ontology and framework theory. With the gradual deepening of studies on conceptual change, those theories have been developed, such as cognition-oriented theories were taken social/affective factors into account and different theories were integrated to a multidimensional framework for interpreting conceptual change in classroom, etc. This article reviews theories of conceptual change and their developments, and then makes some suggestions for studies and theories of conceptual change in the future

Key words: conceptual change, epistemology, ontology, framework theory, multidimensional framework for conceptual change in classroom
