Application of the Missouri Mathematics Project (MMP) Model to improve learning outcomes of the Basic Concepts of Mathematics Course for Students in the second semester of the PGSD Study Program

Abstract

This research aims to improve the learning outcomes of students in the second semester of the PGSD Study Program for basic concepts of mathematics using the Missouri Mathematics Project (MMP) learning model. The research method used is Class Action Research (PTK) with the John Elliot model which consists of four stages of planning, implementation of actions, observation and reflection. The subjects of the study are 14 students in the second semester of the 2025/2026 Even semester. Data collection techniques through observation, tests and documentation were then analyzed using mixed methods. The results of the research indicate that there is a gradual increase in completeness starting from pre-cycle, cycle I, cycle II. In the pre-cycle stage, the completeness only reached 33% in the first cycle it increased to 83% and in the second cycle it increased to 100%. The results of this study show that the use of  the Missouri Mathematics Project (MMP) learning model encourages students to be motivated, as well as to increase their understanding of mathematical concepts and learning outcomes.
