Abstract

Abstrak: Studi ini bertujuan untuk mengevaluasi pengaruh penggunaan pembelajaran berbasis proyek (PBP) terhadap kemampuan pemecahan masalah matematika siswa sekolah menengah atas melalui pendekatan Systematic Literature Review. Data diperoleh dari pengindek Scispace dan Elicit dengan pencarian terbatas pada Google Scholar, DOAJ, dan Scopus untuk terbitan tahun 2013 hingga 2023. Hasil penelitian menunjukkan bahwa PBP, terutama dengan pendekatan Project-Based Learning (PBL), memiliki potensi yang signifikan dalam meningkatkan kemampuan pemecahan masalah matematika. Faktor-faktor pendukung, seperti desain pembelajaran yang sesuai dan kemampuan guru, serta integrasi nilai-nilai Islami dalam konteks pembelajaran matematika, juga diidentifikasi sebagai elemen penting dalam meningkatkan prestasi belajar dan pengembangan karakter siswa. Temuan ini menekankan perlunya integrasi PBP dalam kurikulum untuk meningkatkan efektivitas pembelajaran matematika. Studi ini memberikan landasan bagi penelitian lebih lanjut tentang strategi implementasi yang efektif dan pemahaman yang lebih mendalam tentang pengaruh PBP terhadap pembelajaran matematika di tingkat sekolah menengah atas.Abstract: The study aims to evaluate the impact of project-based learning (PBL) on high school students' mathematical problem-solving abilities through a Systematic Literature Review approach. Data were obtained from Scispace and Elicit indexes, with searches limited to Google Scholar, DOAJ, and Scopus publications from 2013 to 2023. The findings indicate that PBL, particularly when employing a Project-Based Learning (PBL) approach, significantly enhances mathematical problem-solving skills [4]. Supporting factors such as appropriate instructional design, teacher competence, and the integration of Islamic values in the context of mathematical learning, are also identified as crucial elements in improving learning outcomes and student character development. These findings underscore the importance of integrating PBL into the curriculum to enhance the effectiveness of mathematical instruction. The study provides a foundation for further research on effective implementation strategies and a deeper understanding of the impact of PBL on mathematics education at the high school level.

Abstract

This study aims to describe the statistical literacy skills of prospective mathematics teachers in terms of Adversity Quotient (AQ). This study uses a qualitative descriptive research method. The subjects of this study came from 100 prospective mathematics teachers from UIN Mataram. The selection of subjects was based on the results of the adversity quotient questionnaire with the climber, camper and quitter types and students who tend to be able to master statistical literacy based on the results of problem-solving tests. Data collection techniques used adversity quotient questionnaires, statistical literacy test instruments and task-based interviews. While data analysis refers to the statistical literacy framework. The results of this study are that there is no significant difference between the statistical literacy skills of the climber, camper, and quitter types. All three are able to understand and present data well. The difference between these three types lies in the ability of each type to interpret data and communicate data, both verbally and in writing.

Abstract

This study aims to describe the translation of representation in understanding the Pythagorean theorem in terms of students' learning styles. Representation has an important role in learning mathematics. Representation as a means of understanding concepts and mathematical thinking and revealing conceptual understanding. The research method uses a qualitative approach. The subjects of this study came from 85 mathematics education students from the State Islamic University of Mataram. The selection of subjects was based on the results of a learning style questionnaire with categories of visual learning style, auditory learning style, and kinesthetic learning style. Data collection techniques used a learning style questionnaire, a Pythagorean theorem test instrument and task-based interviews. This study has proven that students successfully completed the Pythagorean theorem problems because they were able to carry out the translation process from verbal to visual representation and from visual to symbolic. This indicates that understanding concepts and the ability to change information in various forms of representation greatly influence success in solving mathematical problems.

Abstract

This study seeks to elucidate the impact of self-efficacy on learning motivation and mathematics learning outcomes of seventh-grade students enrolled at a school in Mataram City. Furthermore, it explores the role of learning motivation as a mediating variable in this relationship. Employing a quantitative approach with a correlational design, the study sample comprises 168 individuals, selected through a simple random sampling technique. Data was collected via a questionnaire assessing self-efficacy, learning motivation, and mid-term test scores. The path analysis revealed that self-efficacy exhibited a positive and statistically significant influence on both learning motivation (86.8%) and learning outcomes (21.9%). Conversely, learning motivation did not demonstrate a significant impact on learning outcomes (7.6%) nor did it mediate the association between self-efficacy and learning outcomes. This study underscores the paramount significance of self-efficacy in fostering learning motivation. While increased motivation may not directly translate into enhanced learning outcomes, it necessitates the implementation of more effective learning strategies and teacher support to augment student achievement.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Problem Based Learning (PBL) berbantuan media roda pintar trigonometri terhadap prestasi belajar siswa ditinjau dari gaya belajar. Metode penelitian yang digunakan adalah pra-eksperimen dengan desain one group pretest-posttest design. Subjek penelitian terdiri atas 40 siswa SMA Islam Abhariyah yang dikelompokkan berdasarkan gaya belajar auditori, visual, dan kinestetik. Instrumen penelitian berupa tes prestasi belajar pada materi trigonometri. Analisis data menggunakan uji normalitas, dan One Way ANOVA. Hasil uji normalitas menunjukkan bahwa data penelitian berdistribusi normal, sehingga memenuhi syarat untuk dilakukan analisis parametrik. Hasil analisis One Way ANOVA menunjukkan adanya perbedaan yang signifikan prestasi belajar siswa ditinjau dari gaya belajar dengan nilai signifikansi < 0,05. Dengan demikian, dapat disimpulkan bahwa penerapan model pembelajaran PBL berbantuan media roda pintar trigonometri berpengaruh positif terhadap prestasi belajar siswa, serta dipengaruhi oleh perbedaan gaya belajar yang dimiliki siswa. Ditinjau dari gaya belajar, kelompok visual memperoleh peningkatan prestasi paling tinggi, disusul kelompok auditori dan kinestetik.

Abstract

Mathematical communication skills are essential for students to understand, construct, and express mathematical ideas. However, studies linking these skills with affective factors such as self-confidence remain limited, particularly in learning exponents. This study aimed to examine the relationship between students’ self-confidence and their mathematical communication skills in exponent learning. A qualitative case study design was applied to 53 eleventh-grade students at SMA Negeri 1 Pringgasela. Data were obtained through a mathematical communication test, a validated self-confidence questionnaire, and in-depth interviews. The results show variations in communication skills across self-confidence levels. Students with high self-confidence communicated ideas more comprehensively through oral, written, and visual representations. Students with moderate self-confidence demonstrated adequate but restricted forms of representation, while those with low self-confidence struggled to articulate ideas consistently. These findings emphasize the significant role of affective factors in shaping mathematical communication. The study suggests that instructional strategies should not only focus on conceptual mastery but also foster students’ self-confidence through collaborative activities, discussions, and presentations. This contributes practically to classroom practice and theoretically to the integration of affective and cognitive aspects in mathematics learning, particularly in the context of exponents.
