Origins of Misconceptions

Students come into our classrooms with many misconceptions about science in general and astronomy in particular (see numerous papers and references in Novak, 1993 and Pfundt & Duit 1993). These beliefs evolve from a variety of sources throughout childhood and adolescence (Comins, 1993a, 1993b, 1995). I have found that directly addressing these incorrect beliefs in the context of their origins helps my students replace them with correct knowledge. By understanding the origins of their misconceptions students can screen information more effectively, i.e., they learn to think more critically. My purpose in this paper is to briefly identify origins of misconceptions and classroom techniques for replacing them.

I define misconceptions as deep seated beliefs that are inconsistent with accepted scientific information. Unless we directly address these incorrect ideas at their roots, most students cannot replace them with correct knowledge. Most students retain correct material only long enough to pass tests, and then lapse into believing their prior misconceptions.

In previous works (Comins, 1993a & 1995) I identified a heuristic set of origins that account for all the misconceptions I have identified. It is well worth noting that such a list is by no means unique and, given that I have since added another category, nor is it complete. Nevertheless, this set of origins is an extremely practical one, providing a significant set of tools for understanding and dissecting misconceptions and how these beliefs are used by different people. In an effort to make this set more tractable, I have now revised it to an even dozen (see Sections 1.1–1.12).
