β¦ Synopsis
The project of "conceptual change" has assumed a central place in science education, as both a research program and professional maxim. Conceptual change flags the transformation of students' naive conceptualizations of science into the scientific understandings of their curriculum. This article organizes a reading of the literature that brings into view a collection of design specifications for a conceptual change apparatus. Moving from the conceptual to the practical, it then pursues an analysis of one such apparatus, in the particulars of a science education demonstration program produced by the Harvard-Smithsonian Private Universe Project.
