EFFECTIVENESS OF MICRO TEACHING: DEVELOPING STEM TEACHING ORGANIZING SKILLS FOR PRE-SERVICE CHEMISTRY TEACHERS
The research aims to determine the effectiveness of micro teaching in developing STEM teaching organizing skills for pre-service Chemistry teachers (teaching organizing skills for pre-service Chemistry teachers - TOSfPCT). This approach was evaluated through the constructivism and experiential learning theories. This research was conducted within a course for six weeks period during the 2nd semester of the 2020-21 academic year at a Chemistry faculty, Hue University of Education. The article presents the micro-teaching process combined with the application of information technology in developing STEM TOSfPCT, pre-\post-test quasi-experimental design with control group was applied. The experiment involved applying micro teaching to the experimental group (EG) while the courses were carried out using traditional lectures in the control group (CG). Mann Whitney U Test and Wilcoxon Sign Test were used in the analysis of the quantitative data. The results obtained from Mann Whitney U Test and Wilcoxon Sign Test suggest that there is no significant difference between the pre-test scores of the experimental and the control groups. Descriptive data also demonstrated that the use of the micro teaching in the curriculum had significantly increased the skill levels of the experimental group pre-service Chemistry teachers.
