Efforts to Improve Students' Mathematical Understanding Ability on Social Arithmetic Materials through Problem-Based Learning Models

Abstract

The purpose of this study was to improve students' mathematical understanding skills with social arithmetic material through problem-solving integrated into the Problem Based Learning learning model. This research method is classroom action research that follows the model of Kemmis and Taggart. This research includes 3 cycles; each cycle includes 4 stages, namely planning, implementation, observation, and reflection. The participants in this study were 27 grade VII students of SMP Nahdlatul Ulama Megamendung Bogor. Data was collected through tests, interviews, and observations. The results showed that there was a significant increase in the ability of seventh-grade students to understand mathematics. This is evidenced by the increase in the average math test results in each cycle, cycle 1 = 63.15; cycle 2= 75.00; cycle 3 = 81.48, and the results of the interviews concluded that learning mathematics through integrated problem-solving model Problem-Based Learning is fun for students. This study concludes that this model can improve students' mathematical understanding skills on social arithmetic material in class VII SMP Nahdlatul Ulama Megamendung Bogor in the 2021/2022 school year.
