Use of the four-tier diagnostic test with PIMCA model on learning of microscope

Abstract

In learning physics, students often find misconceptions. This research aims to determine misconceptions on the subject of an optical microscope by using the four-tier diagnostic test with the PIMCA model (Presentation, idea mapping, conceptualization, and assessment formative) which was introduced and developed by Cosmas Poluakan. The method used is the One Group Pre-test – Post-test Design with 24 respondents as prospective physics teacher’s students at the Department of Physics, Manado State University. The instrument used is a test instrument in the form of a (four-tier diagnostic test). The research started with the pre-test, the implementation of the physics learning followed the 4 steps of the PIMCA model and ended with a post-test. The results showed a pre-test average value of 45 and the average post-test value of 93. Based on the research results, it is shown that the learning outcomes of the students with the PIMCA MR-SR learning model increase on the subject of the optical microscope.
