EVALUATION OF PRE-SERVICE SCIENCE TEACHERS' CONCEPTUAL UNDERSTANDINGS ON THE TOPIC OF “COLLIGATIVE PROPERTIES” ACCORDING TO WALTON ARGUMENT MODEL COMPONENTS

Abstract

The purpose of this research is to determine the conceptual understanding of pre-service science teachers about “Colligative properties”, which are aimed to be taught within the scope of Chemistry-II course, within the framework of the argumentation-supported problem based learning (AS-PBL) method. The study, in which 24 pre-service science teachers participated, was conducted as practice-based action research, which is one of the qualitative research methods. The arguments of pre-service science teachers about the related chemistry topic were analysed according to the Walton Argumentation Model (Conclusion-Premise) and were described through content analysis. At the end of the research, it was observed that pre-service science teachers had misconceptions of arguments, which they mostly structured as a "conclusion sentence", about the related chemistry topic before the implications. After the implications, it was observed that the majority of pre-service science teachers showed the ability to present “a conclusion and at least one premise”, but the conceptual understanding of all participants did not reach the expected level.
