Student Profile Multiple Representations Skills Under the Implementation of Obsim (Observation and Simulation) Model of Teaching in Improving Creative Thinking Skills

Abstract

The research aims to explore multiple representations under the implementation of the OBSIM model of teaching in the alternating-current circuit course. This research compares the modern class (experimental class) and traditional class with the traditional teaching style. Experiment class applies the OBSIM model of teaching, and Traditional Classroom teaches in traditional style with a direct explanation. Computer simulation also integrated into this research by using Matlab Sofware as part of multiple representations, namely programming representation. This research used triangulation methods. The quantitative methods were applied to analyze student achievement tests according to Creative thinking criteria. The Qualitative method was applied using observation of student activity. Student achievement test followed by a pretest, and post-test quasi-experimental research. The data analysis form pretest and postest analysis indicates a significant value of 0.012 (p ≤ 0.05). Thus, it is a significant value, and the average of student activity in experimental class better than control class. The findings conclude that two classes have differences in terms of student multiple representations and creative thinking skills after implementation of OBSIM model of teaching
