This study is quantitative research with a quasi-experimental approach. The research design is a non-equivalent control group, covering two classes, namely the control and experimental classes. The aim is to explore the influence of the Missouri Mathematics Project (MMP) learning model on mathematics problem-solving skills based on the self-efficacy of elementary students. The population of the study was all students of grade 5 at SD Negeri 3 Parepare, South Sulawesi, which involved two classes. A cluster random sampling approach was used to determine the sample. Data collection techniques used tests to obtain the results of mathematics problem-solving skills, observation sheets for learning implementation, and questionnaires for students' self-efficacy. Descriptive and inferential statistical analysis techniques were used to examine data analysis methodologies. The study's results reveal that 1) implementing the MMP and Discovery Based Learning model can improve students' mathematics problem-solving skills. 2) there is a difference in the effect of students' mathematical problem-solving abilities who have high self-efficacy after applying the MMP learning model and Discovery Based Learning. © 2023 Author(s).
