Abstract

Problem solving skills are important for students to overcome various problems related to learning and community life. This involves students actively exploring, observing, trying, and investigating using the knowledge and abilities they have. Problem solving is the main focus of developing students' higher order thinking skills in mathematics. This research was conducted by means of observation, interviews, and post-test methods on the 4th grade students of SD Negeri 7 Gondosari. In the results of the discussion, there are 10 data from 31 students which can describe a good level of problem solving. Some students experienced difficulties in implementing the problem and re-examining the results of the solution. Therefore, it is important for students to continue to hone their problem solving abilities using the Polya procedure and to re-check the correctness of the solutions that have been done.

Abstract

This research aims to investigate the influence of using Bali orange media through the Realistic Mathematics Education (PMRI) approach on the subject of area and perimeter of flat shapes among sixth-grade students at SDN 7 Gondosari. The research method employed is quantitative descriptive. The sample was obtained using Nonprobability Sampling technique with a total sampling method, involving a population of 36 students, which also represents the sample size in this study. The data collection instrument used was a test. Data collection techniques involved observation, tests, and documentation. The research findings indicate that the average learning outcome, previously at 50, increased to 70. Therefore, the use of Bali orange media influences students' learning outcomes.
