Abstract

Penelitian ini  bertujuan untuk menganalisis kemampuan literasi matematika dalam menyelesaikan soal matematika PISA berdasarkan level kemampuan literasi matematika pada peserta didik SMPN 13 Mataram Tahun Ajaran 2024/2025. Penelitian ini merupakan penelitian kualitatif deskriptif dengan melibatkan 52 peserta didik kelas IX A dan IX B, kemudian dipilih 8 peserta didik sebagai subjek. Instrumen penelitian yang digunakan adalah tes kemampuan literasi matematika yang diadaptasi dari PISA dan pedoman wawancara. Data dianalisis berdasarkan indikator proses literasi matematika (formulate, employ, interpret). Hasil penelitian menunjukkan bahwa dari 6 level kemampuan literasi matematika tidak ada peserta didik yang mencapai level 5 dan 6. Pada level 1 mampu merumuskan informasi eksplisit dan menyelesaikan soal dengan algoritma sederhana, level 2 dapat mengidentifikasi informasi implisit serta memilih strategi dasar untuk memecahkan masalah, level 3 mampu mengolah informasi eksplisit kompleks yang mengandung pengecoh dan menyusun strategi berurutan untuk pengambilan keputusan, sedangkan Level 4 bisa merumuskan informasi eksplisit dalam konteks kehidupan sehari-hari serta menerapkan strategi untuk situasi konkret yang kompleks. Peserta didik level 1-4 juga memiliki kemampuan menafsirkan dan menyimpulkan hasil sesuai konteks permasalahan.

Abstract

This study aims to examine the effect of growth mindset on self-efficacy, as well as its influence on students’ learning outcomes in the Pythagoras' Theorem topic, both directly and indirectly through the mediation of self-efficacy, among eighth-grade students at SMPN 15 Mataram in the 2024/2025 academic year. This research employed a quantitative approach with an ex-post facto design. The population consisted of 371 students, and a sample of 54 students from classes VIII-B and VIII-G was selected using cluster random sampling. Data were collected through questionnaires and tests, and analyzed using SPSS software along with the Macro PROCESS Model 4 to test the mediation model. The results showed that 1) growth mindset had a positive and significant effect on students’ self-efficacy (a=0,740, p<0,001); 2) there was no significant direct effect of growth mindset on learning outcomes (c'=0,349, p=0,249); 3) there was a positive and significant indirect effect of growth mindset on learning outcomes through the mediation of self-efficacy (ab=0,930, CI [0,478 to 1,438]), indicating full mediation. Thus, self-efficacy is proven to act as a full mediator in the relationship between growth mindset and students’ learning outcomes.

Abstract

The background of this study is the low student learning outcomes, the ineffective learning process, and the lack of teacher interaction. This research aims to examine the effectiveness of using TPACK-integrated learning media on the learning outcomes of exponent numbers among eighth-grade students at SMP Negeri 1 Kediri. The research approach used is quantitative, with a research design of Pretest-Posttest Only Control Group Design. The population in this study includes all eighth-grade students at SMPN 1 Kediri, and the sampling technique used is purposive sampling. The selected sample consists of class VIIIC as the control group and class VIIIE as the experimental group. The research instruments include test questions, observations, and student response questionnaires. The data analysis techniques used in this study are descriptive and inferential statistical analysis. The learning media used include instructional videos, Liveworksheets-based LKPD, and Kahoot. The results of the study indicate that the use of TPACK-integrated learning media is effective in improving the learning outcomes of exponent numbers among eighth-grade students at SMP Negeri 1 Kediri in the 2024/2025 academic year. This effectiveness is demonstrated by: (1) An increase in the average learning outcomes of the experimental class by 0.7342, which falls into the high category. (2) A significant difference in the average mathematics learning outcomes between the control and experimental classes, as indicated by the independent sample t-test, where t_calculated > t_table (6.104 > 2.005).

Abstract

This research aims to determine the effect of the cooperative learning model typeTwo Stay Two Stray (MP-TSTS) on the mathematics learning outcomes of class VIII students at MTs Al Aziziyah Putra Gunungsari. The type of research used is quantitative descriptive researchPost-test Only Control Design. The population in this study were all class VIII students at MTs Al Aziziyah Putra Gunungsari, consisting of 8 classes. The sample in this research was students in classes VIII A and VIII B. The instrument used in this research was a learning outcomes test. The data collected consists of student learning outcomes data. Data were analyzed using descriptive analysis. Results of inferential analysis using test independent sample t-test with the help ofSPSS 23 to test the hypothesis shows that the student learning outcomes data on post-test, gain normalized and student learning outcomes data with a significant value (2-tailed) < 0.05, namely 0.029. So the learning outcomes of students who use MP-TSTS and students who use the small group discussion method are significantly different. This means that MP-TSTS has an effect on improving learning outcomes. Based on the results of the inferential analysis, it can be concluded that the implementation of MP-TSTS is effective/influenced on the mathematics learning outcomes of class VIII students at MTs Al Aziziyah Putra Gunungsari for the 2022/2023 academic year.

Abstract

This qualitative descriptive research aims to describe students' mathematical problem solving abilities based on Polya indicators in solving social arithmetic problems in terms of self-efficacy. The research subjects were 4 students in class VII of SMP Negeri 4 Gunung Sari for the 2022/2023 academic year, consisting of 2 students in the high category and 2 students in the low category. Data collection techniques using questionnaires, tests and interviews. Data analysis techniques include data reduction, data presentation, and drawing conclusions. The results of this research were obtained from (i) students with level self-efficacy high have high mathematical problem solving abilities can go through all stages of problem solving abilities, namely understanding the problem, preparing a plan, implementing the plan, and checking again. (ii) students by level self-efficacy Low students have low mathematical problem solving abilities which can also be seen from the results of students' work through only two stages, namely the stage of understanding the problem and implementing the plan. With suggestions for students who are at each category level self-efficacy and the level of mathematical problem solving abilities, it is hoped that they can further maximize their abilities

Abstract

This study aims to develop Technological Pedagogical Content Knowledge (TPACK)-based learning media oriented towards motivation and mathematics learning outcomes that are valid, practical and effective. The subjects in this study are class VIII students at one of the junior high school in Mataram. This type of this study is Research and Development with the ADDIE (Analysis, Design, Development, Implementation and Evaluation) model. Data analysis in this study was carried out using descriptive quantitative and qualitative regarding the advisibility of learning media obtained from assessment or validation sheets, analysis of the practicality of learning media obtained from student response questionnaires and teacher responses to learning media, and analysis of the effectiveness of learning media obtained from posttest results. The study results obtained that:  TPACK-based learning media has been developed is suitable for use as learning media with high validity; TPACK-based learning media is practically used as learning media with a practicality score of 79.67%;  The N-gain value for increasing students matemathics learning motivation is 43.34% in the medium category, while for increasing students matemathics learning outcomes it is 56.74% in the medium category. Based on the results, TPACK-based learning media is suitable for use, practically applied for learning, less effective for increasing learning motivation, and quite effective in improving learning outcomes
