Individuals of all ages have misconceptions about phenomena of the natural and physical world. They may think, for example, that summer is hotter because the Earth is closer to the Sun, and it is colder in winter because the Earth is farther away from the Sun. This explanation is not compatible with the scientific explanation of the phenomenon. Scientific learning often implies the revision of naïve conceptions, or conceptual change, which is not a quick and easy process. Researchers have addressed the question of the nature of conceptual change in terms of what the acquisition of new science knowledge entails when students hold misconceptions and need to revise their mental representations. Various approaches have been proposed to account for the mechanisms that underlie conceptual change and to draw implications for teaching and learning processes.
For some decades conceptual change was only examined from a purely cognitive perspective (“cold” conceptual change), while more recently motivational and emotional aspects (“warm” conceptual change) have received attention. Research findings indicate that individual differences in misconceived prior knowledge, along with differences in achievement goals, self-efficacy, interest, and epistemic beliefs, as well as differences in the emotions experienced in learning contexts, are all associated with conceptual change. More recently, research has challenged the idea that misconceptions disappear permanently after conceptual change has taken place. Previously acquired, incorrect information still competes with the newly acquired correct information. The executive function of inhibition seems to be involved when naïve and scientific conceptions co-exist in the learner’s memory and the latter is used to produce a correct answer. Further research is needed on the role of inhibitory control in relation to learning concepts and affective states during scientific learning.
