The Influence of Learning Discipline on Mathematics Learning Outcomes of Eighth-Grade Students at SMP Darur Rahmah Jember on the Pythagorean Theorem Material

Abstract

This study aimed to determine the influence of learning discipline on the mathematics learning outcomes of eighth-grade students at SMP Darur Rahmah Jember on the Pythagorean Theorem material. This research employed a quantitative approach using a correlational research design. The sample consisted of 17 students selected through purposive sampling techniques. The instruments used in this study were a learning discipline questionnaire and mathematics achievement tests in the form of pre-test and post-test. The collected data were analyzed using descriptive statistics and the Paired Sample t-Test with the assistance of IBM SPSS Statistics. The results of the study showed that students’ mathematics learning outcomes improved after the implementation of disciplined learning activities. The average pre-test score was 61.41, while the average post-test score increased to 83.29, indicating an average improvement of 21.88 points. The results of the Paired Sample t-Test analysis revealed a significance value (Sig. 2-tailed) of 0.000, which was lower than 0.05. Therefore, the alternative hypothesis (HaH_aHa​) was accepted, indicating that learning discipline had a significant influence on students’ mathematics learning outcomes on the Pythagorean Theorem material. The findings also indicated that students with higher learning discipline tended to demonstrate better conceptual understanding, greater participation during classroom activities, and higher responsibility in completing assignments. Thus, learning discipline can be considered an important factor in improving students’ mathematics achievement.
