Ethnomatematic Assisted PBL-Based Teaching Materials to Improve The Problem-Solving Skills of Junior High School Students
Keywords:Teaching Material, Ethnomatematics, PBL
This study has the purpose of analyzing the effectiveness of the Problem-Based Learning model based on ethnomathematics with Selotigo batik motifs in improving students' problem-solving abilities. This study was true experimental design research. The sampling technique was done using random cluster sampling. The sample in this study was junior high school as an experimental class with a total of 34 students. The data collection was done through observation, documentation, and test method. The data analysis was done using One-Sample t-test, Proportion Test, and Independent Sample ttest. The results showed that the PBL model based on ethnomathematics was effective in improving students' problem-solving abilities. This result was indicated by the average score of students' problem-solving ability in the learning using PBL model based on ethnomathematics which was above the Minimum Completeness Criteria (KKM) with KKM of problem-solving abilities of 75, the proportion of students completeness of problem-solving abilities in PBL model based on ethnomathematics was above 75% of the classical completeness, the average problem-solving ability of students in the PBL learning model based on ethnomathematics is better than the average problem-solving ability of students in the PBL model. Based on the result, it can be concluded that problem-solving in a PBL model based on ethnomathematics is effective in improving the problem-solving ability of students
