IMPROVING STUDENT LEARNING OUTCOMES THROUGH PROBLEM-BASED LEARNING MODEL IN MATHEMATICS SUBJECT

This research aims to enhance the learning outcomes of 3 rd grade students at SD Negeri 112 Palembang by applying the problem-based learning model in mathematics on adding fractions with the same denominators. This research uses Classroom Action Research conducted over three cycles: planning, implementation, observation, and reflection. The subjects of this research are 25 students in the 3 rd grade class at SD Negeri 112 Palembang. Data collection is carried out through tests and analysis using quantitative data analysis. By applying the problem-based learning model, the research results demonstrate a significant improvement in the students’ learning outcomes regarding the topic of fractions in mathematics. In cycle I, the level of student learning mastery reached 56%; in cycle II, the level of learning mastery increased to 68%; and in cycle III, it reached 84%. In conclusion, applying the problem-based learning model has effectively improved student learning outcomes in mathematics, particularly in fractions material.
