An important factor for the effectiveness of learning is an assessment factor for both the process and learning outcomes. Research has been carried out related to the use of multiple-choice assessment in the MR-SR based PIMCA (Presentation, Idea Mapping, Conceptualization, Assessment) learning model introduced and developed by Cosmas Poluakan. This study aims to determine the level of understanding of the physics concept of the Doppler effect with the PIMCA model. The research method uses concurrent mixed methods. The research stage began with a pre-test, followed by a PIMCA model treatment which was interspersed with interviews and ended with a post-test. The research was conducted at the Faculty of Mathematics and Natural Sciences, UNIMA, with 24 student teacher candidates as respondents. The research instrument used a multiple-choice model (MMC) with a written test technique. The results of data analysis obtained a pre-test score of 1.25 and a post-test score of 7.13. The results showed that using the PIMCA model using multiple-choice assessment can improve understanding of the concept of the Doppler effect physics material.
