Abstract
The purpose of this study is to investigate the types of middle school students’ responses to dinosaur extinction inconsistent with the students’ previous conceptions. The types of texts about ‘the cause of dinosaur extinction’ were developed; one that was based on students’ previous ideas, while the other was based on conflicting materials. The students’ responses to the conflict materials were classified into six types: rejection, reinterpretation, uncertainty, belief decrease, partial theory change, and conceptual change. These results show that the use of conflict materials does not always promote conceptual change. Therefore, teachers will be able to help students change their conceptions in science classrooms by understanding students’ various responses to conflict materials and designing instructional strategy concretely.
