Abstract
In this study, prospective science teachers' misconceptions about the seasons and the phases of the Moon were determined, and then the effects of 3D computer modelling on their conceptual changes were investigated. The topics were covered in two classes with a total of 76 students using a predict–observe–explain strategy supported by 3D computer modelling. The results of the study suggest that, prior to teaching, the subjects had misconceptions regarding both phenomena, and that the teaching was quite effective regarding conceptual change.
