The Use of Problem Based Learning Model in Improving Student Learning Outcomes in Lessons Mathematics in Grade III of SD Negeri 0121 Tanjung Botung

Abstract

The purpose of this study was to determine the increase in students' mathematics learning outcomes through the use of the PBL (Problem Based Learning) learning model. This type of research is Classroom Action Research (CAR). The subjects of this study were 33 grade III students at SD Negeri 0121 Tanjung Botung consisting of 18 boys and 15 girls. Data collection techniques in this study were carried out by: (1) observation, (2) tests. The data instruments used were: (1) observation sheets for the implementation of learning activities in mathematics using the Problem Based Learning model (2) test sheets in the form of multiple choice questions in mathematics using the Problem Based Learning model. Data analysis techniques in this study used qualitative and quantitative data analysis techniques. Based on the research results, it can be concluded that after conducting research using the Problem Based Learning learning model, the learning outcomes of grade 3 students at SD Negeri 0121 Tanjung Botung have increased in each cycle. In the pre-cycle, there were 14 students who completed with a percentage of 42%, while students who did not complete were 19 with a percentage of 58%. After making improvements in cycle I there was an increase, namely 23 students who completed with a percentage of 69% and students who did not complete were 10 with a percentage of 31% and the highest score in cycle I was 85 and the lowest score was 60 and the average value was 76, the results of cycle I improvements have not yet reached the achievement indicator of 80% completeness, therefore cycle II improvements are carried out. After the implementation of cycle II there was an increase, namely students who completed 30 with a percentage of 90% while students who did not complete were 3 people with a percentage of 10% and the highest score in cycle II was 90 and the lowest score was 65 and the average score was 85. Thus the improvement with the Problem Based Learning model it can be said to be successful because the learning outcomes achieve the goal, namely the percentage of 90%. So it can be concluded that learning with the Problem Based Learning model can improve learning outcomes in mathematics.
