Abstract

This study aims to determine the influence of reflective thinking and self-confidence on the mathematical problem-solving ability of grade VIII students of SMPN 9 Mataram for the 2024/2025 academic year. This research is a quantitative research with an ex-post facto (comparative causal) research method. The population of this study is 163 students in grade VIII of SMPN 9 Mataram for the 2024/2025 academic year. The sample used was 55 people who were determined using the cluster random sampling technique. The instrument in this study used a reflective thinking test in the form of description questions, self-confidence questionnaires and problem-solving ability tests in the form of description questions. The results of the study showed that there was a positive and significant relationship between reflective thinking and self confidence on the mathematical problem-solving ability of grade VIII students of SMPN 9 Mataram with a contribution of 49,9%. The results of this research are expected to be an input for teachers to develop learning that encourages students to think reflectively and build confidence in solving math problems. For students, it is important to continue to practice reflective thinking skills and increase self-confidence to support the achievement of optimal learning outcomes.

Abstract

This study aims to determine the effect of self-efficacy and creative thinking ability on the mathematics learning outcomes of eighth-grade students at SMP Negeri 5 Mataram for the academic year 2023/2024, both partially and simultaneously. This research is quantitative with an ex-post facto research method. The population of this study consists of 254 eighth-grade students at SMP Negeri 5 Mataram for the academic year 2023/2024. A sample of 64 students was selected using simple random sampling technique.The instruments tested were valid and included a self-efficacy questionnaire, a creative thinking ability questionnaire, and a mathematics learning outcome test in the form of multiple-choice questions. The results of the descriptive statistical analysis showed that the average self-efficacy score of students was 57.09, categorized as moderate; the average score for creative thinking ability was 46.98, also categorized as moderate; and the average score for mathematics learning outcomes was 59.76, categorized as low.The results of the study showed that: 1) there was a significant effect of self-efficacy on the mathematics learning outcomes of eighth-grade students at SMP Negeri 5 Mataram in the 2023/2024 academic year, with a contribution of 16.4%; 2) there was a significant effect of creative thinking ability on the mathematics learning outcomes of these students, with a contribution of 14.3%; and 3) there was a jointly significant effect of self-efficacy and creative thinking ability on mathematics learning outcomes, with a combined contribution of 23.7%.
