Teaching convex Lens materials with a PIMCA model

Abstract

This research is based on learning physics on convex lens material with the PIMCA model based on MR-SR (multiple representation - semiotic source). PIMCA (Presentation, Idea Mapping, Conceptualization, Formative Assessment) is a new learning model based on MR-SR which was introduced and developed by Cosmas Poluakan. This study aims to see the increase in the average learning outcomes of physics education students in the odd semester. The method used in this research is quantitative comparative design with one group pretest-posttest design. The research was conducted in the physics education department of Manado State University with 24 students as respondents. The instrument used has been tested and validated. The research procedure starts from the initial study on students and then the pretest then performs 4 stages of the PIMCA model (presentation, idea mapping, conceptualization, formative assessment) then posttest. From the results of data processing & analysis, it was found that the average pretest score was 23 and the average posttest score was 79 with a standard ideal value of 75, then the gain-test value was 1.0769 where the data showed a high increase in learning outcomes after the implementation of PIMCA. And it can be concluded that the PIMCA learning model is very good at improving understanding of the concept of the convex lens.
