Abstract

This article aims to describe the abductive reasoning process in solving algebra. In this research, the literature study method was used. Based on the results of studies that have been conducted, abductive reasoning helps students make creative and flexible guesses, especially when the solution is not clear at the start. By applying abductive reasoning to solve algebra problems, students are directed to recognize abductive problems, identify various solutions then select the best solution, and assimilate. The solution found must be re-evaluated because there is no guarantee that the solution obtained from the abductive reasoning process is correct.

Abstract

This study aims to analyze the effectiveness of using triangle-shaped teaching aids in improving students' learning outcomes in geometry concepts, particularly triangles. The research employed a quasi-experimental approach with a "Nonequivalent Posttest-Only Control Group" design to evaluate differences in learning outcomes between the experimental and control groups. The sample comprised eighth-grade students at MTS Buaran Tangerang, divided into two groups: the experimental group using teaching aids and the control group following conventional methods. Data were analyzed using normality tests, Pearson correlation tests, and t-tests. The findings reveal that using triangle-shaped teaching aids significantly enhances students’ understanding of triangle concepts. The experimental group achieved higher average learning outcomes compared to the control group. Correlation analysis indicated a strong positive relationship between the use of teaching aids and students' learning outcomes. This study concludes that triangle model teaching aids serve as an effective learning medium to facilitate understanding of abstract mathematical concepts. The findings underscore the importance of innovation in educational tools to support more interactive and meaningful learning processes.

Abstract

Kemampuan pemecahan masalah matematika sangat penting bagi siswa dalam menghadapi tantangan pembelajaran dan kehidupan sehari-hari. Penelitian ini bertujuan mendeskripsikan kemampuan pemecahan masalah matematika di kalangan siswa Madrasah Aliyah. Penelitian dilakukan dengan pendekatan deskriptif kualitatif, melibatkan 6 siswa kelas XI dengan kategori kemampuan hafalan Alquran tinggi, sedang, dan rendah. Instrumen yang digunakan adalah tes masalah matematika dan pedoman wawancara. Tes masalah matematika mencakup empat tahap utama yaitu memahami masalah, merancang solusi, melaksanakan rencana, dan memeriksa hasil. Temuan menunjukkan bahwa mayoritas siswa memiliki kemampuan pemecahan masalah sedang, dengan kelemahan utama pada tahap memeriksa hasil. Faktor yang mempengaruhi kemampuan ini meliputi pemahaman konsep matematika, keterampilan berpikir logis, dan daya ingat siswa. Triangulasi dilakukan dengan membandingkan hasil wawancara dan tes tertulis. Siswa dengan kemampuan hafalan rendah berada pada level unistruktural, hanya memahami masalah secara terbatas dan menyelesaikannya berdasarkan informasi yang sedikit, sehingga kesimpulan yang diambil kurang akurat. Siswa dengan kemampuan hafalan sedang berada pada level multistruktural, memahami masalah dengan baik, merencanakan penyelesaian menggunakan rumus trigonometri, namun kesulitan menghubungkan konsep-konsep matematika dengan informasi yang ada, sehingga kesimpulannya kurang tepat. Siswa dengan kemampuan hafalan tinggi mencapai level relasional. Siswa mampu menghubungkan berbagai konsep yang dipelajari, memahami hubungan antar elemen, serta menerapkannya untuk memecahkan masalah secara terpadu. Selain itu, siswa juga memeriksa kembali langkah-langkah dan jawabannya untuk memastikan kebenarannya.

Abstract

This study aims to analyze the needs of Madrasah Aliyah (MA) teachers in Purworejo Regency in utilizing artificial intelligence (AI) as a medium for learning mathematics. A descriptive qualitative approach was used with a data triangulation method to increase the validity and reliability of the study. Data were collected through questionnaires, in-depth interviews, and documentation involving 10 mathematics teachers with various age backgrounds, teaching experiences, and levels of knowledge about AI. The results showed that the majority of teachers (80%) were familiar with AI, while the rest were still less familiar. The most frequently used AI application was Geogebra (40%), followed by Canva and Quizizz (each 20%). The main obstacles faced by teachers were the lack of adequate facilities (70%), time constraints in learning AI (10%), limited school budget (10%), and low understanding of AI (20%). In addition, teachers need ongoing technical training, AI implementation guidance, and infrastructure support, such as internet access and hardware. This study concluded that intensive training, procurement of technology facilities, and collaboration between schools and the government are essential to optimize the use of AI in mathematics learning. These findings contribute to the development of technology-based education policies for Madrasah Aliyah.

Abstract

This study aims to develop a Student Worksheet (LKS) based on Realistic Mathematics Education (RME) with a Sundanese cultural context to enhance students' numeracy literacy skills. The research background stems from the low numeracy literacy of students, attributed to conventional mathematics teaching methods that have not optimally developed these competencies. The research method employs Research and Development (R&D) using the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). Validation results by material experts indicate that the LKS is highly feasible, with an average score of 90.53%, while validation by teaching material experts yields an average score of 95.42% (also categorized as highly valid). The practicality of the LKS was assessed based on teacher evaluations, scoring an average of 93.33%, and student questionnaire responses, with an average score of 82.78%. Effectiveness tests conducted at SMPN 3 Sukabumi City demonstrated a significant improvement in students' numeracy literacy, marked by an average n-gain score of 60%. Based on these findings, it is concluded that the RME-based LKS with a Sundanese cultural context is feasible and effective as a learning support tool to enhance students' numeracy literacy
