An Overview of Conceptual Change Models: Some Cases from Physics

As Halloun & Hestenes (1985) have shown, many students come to college physics courses with misconceptions and leave with them as well. In this review, it is attempted to explain the nature of conceptual change models of Posner et al. (1982), diSessa (1993), Vosniadou (1992, 1994, and 2002), and Chi et al. (1994) that take place in the construction of new knowledge of physics and physical science. It is discussed that conceptual change models can lead to a framework for improving science teaching and construction of new knowledge in science. In addition, some examples from physics are given to elucidate these conceptual change models.
