Abstract

Penelitian ini dilatarbelakangi oleh rendahnya kemampuan literasi matematis siswa SMK dalam menyelesaikan soal kontekstual materi matriks serta ditemukannya gejala kecemasan matematika (math anxiety) yang diduga memengaruhi proses berpikir siswa. Tujuan penelitian ini adalah untuk menganalisis kemampuan literasi matematis siswa ditinjau dari tingkat math anxiety yang dimiliki. Penelitian menggunakan pendekatan deskriptif kualitatif. Subjek penelitian adalah siswa kelas XI SMK Swasta Parulian 3 Medan yang berjumlah 21 orang. Data dikumpulkan melalui tes tertulis kemampuan literasi matematis, angket math anxiety, wawancara, dan dokumentasi. Instrumen penelitian telah diuji validitas dan reliabilitasnya. Hasil penelitian menunjukkan bahwa: (1) tingkat math anxiety siswa didominasi kategori sedang (72%), diikuti tinggi (14%) dan rendah (14%); (2) siswa dengan math anxiety rendah dan sedang memiliki kemampuan literasi matematis yang lebih baik dibandingkan siswa dengan math anxiety tinggi; (3) siswa dengan math anxiety tinggi mengalami kesulitan dalam memahami informasi soal, menentukan strategi penyelesaian, menggunakan simbol matematika, serta memberikan kesimpulan. Simpulannya, tingkat math anxiety berpengaruh terhadap kemampuan literasi matematis siswa, di mana semakin tinggi kecemasan matematika, semakin rendah kemampuan literasi matematis yang ditunjukkan

Abstract

This study aims to analyze the comparison of cooperative learning models, Jigsaw and Think Pair Share (TPS), on students’ mathematical problem-solving abilities in the topic of exponent properties among tenth-grade students at SMK Free Methodist Medan in the 2025/2026 academic year. The research method employed was a quasi-experimental design with a pretest-posttest group design. The population consisted of all tenth-grade students at SMK Free Methodist Medan, while the sample included two classes: class X RPL taught using the Jigsaw model and class X TKJ taught using the TPS model. The research instrument was an essay test developed based on mathematical problem-solving indicators, and the data were analyzed using an independent samples t-test.The results of the study indicate that: (1) there is a significant difference in mathematical problem-solving abilities between students taught with the Jigsaw and TPS models (sig. 0.023 < 0.05), and (2) the Jigsaw learning model is more effective than the TPS model in improving students’ mathematical problem-solving abilities (sig. 0.011 < 0.05). Therefore, the Jigsaw learning model is recommended as a superior alternative cooperative learning strategy to enhance students’ mathematical problem-solving skills in the topic of exponents at the vocational high school level

Abstract

This study aims to determine the effect of the deep learning-based problem solving model on students' mathematical problem-solving ability in statistics story problems in class X of SMA Negeri 12 Medan. The research used a Quasi-Experimental method with a population of all grade X students consisting of 10 classes. The sample was determined through cluster random sampling, resulting in class X-E2 as the experimental class and class X-E4 as the control class. Data were collected using a mathematical problem-solving ability test. Data analysis using the Liliefors normality test, F homogeneity test, and t-test showed a significant difference between the pre-test and post-test scores of problem-solving ability in both classes, with a sig. (P(T<=t) two-tail) value of 0.0076 < 0.05. The average post-test score of the experimental class reached 67.3000, while the control class was 46.0333, indicating that students' mathematical problem-solving ability was in the high category. Based on the calculation of Effect Size (Cohen’s D), a value of 3.539734 was obtained, which means that using the problem-solving model based on deep learning on students' mathematical problem-solving abilities has a high influence on improving students' ability to solve mathematical problems
