Abstract

This study aims to determine the types of errors and the factors causing these errors by seventh-grade students at SMP Negeri 99 Jakarta when solving mathematics problems involving integer arithmetic operations. This study is a descriptive qualitative study. Data collection was conducted using tests and interviews. Written tests were conducted to identify students' errors based on Soedjadi's mathematical concepts, which are categorized into factual errors, conceptual errors, principle errors, and operational errors. Interviews were conducted to determine the cognitive aspects contributing to students' errors. Data analysis was conducted using a qualitative descriptive approach, consisting of several stages: data reduction, data presentation, and drawing conclusions. The results showed that conceptual errors were the most common errors made by students when solving arithmetic problems involving integers. The cognitive factors contributing to these errors were remembering (C1), understanding (C2), and applying (C3)

Abstract

This study aims to produce a valid and feasible electronic student worksheet (E-LKPD) using a Game-based Learning method assisted by the Liveworksheets application on the material of two-variable linear equation systems. The research method used is developmental research with the ADDIE research model through the stages of analyze, design, develop, implementation, and evaluation. This research was conducted at SMP Negeri 109 Jakarta with data collection techniques in the form of interviews and questionnaires, which were then analyzed using a combination method with an embedded concurrent model. The validity and feasibility of the media can be found in the results of validation and suggestions and comments from expert validators, as well as assessments from teachers and students. The validity and feasibility results from the expert validators were 93.7% (very valid) and media assessments from teachers and students were 90.6% (very feasible). The results of this study indicate that the learning media developed is feasible to be used in school learning.

Abstract

Kemampuan pemecahan masalah matematika memerlukan kegiatan pembelajaran yang membimbing siswa melalui langkah penyelesaian secara sistematis. Hasil evaluasi awal di SD Negeri 15 Pangkalpinang menunjukkan bahwa siswa masih mengalami kesulitan, terutama dalam memilih strategi, melaksanakan penyelesaian, dan memeriksa kembali jawaban. Tujuan: Penelitian ini bertujuan mengembangkan media pembelajaran interaktif berbasis teori pemecahan masalah Polya serta mengetahui kevalidan, kepraktisan, dan efektivitasnya dalam melatih kemampuan pemecahan masalah matematika siswa sekolah dasar. Metode: Penelitian menggunakan metode Research and Development (R&D) dengan model ADDIE yang meliputi Analysis, Design, Development, Implementation, dan Evaluation. Sebanyak 48 siswa kelas V terlibat dalam seluruh tahapan pengembangan, yaitu 3 siswa pada uji coba one-to-one, 6 siswa pada uji coba kelompok kecil, 15 siswa pada uji coba lapangan, dan 24 siswa pada uji efektivitas. Data dikumpulkan melalui wawancara, lembar validasi ahli, angket respons siswa, pretest, dan posttest. Data kuantitatif dianalisis menggunakan uji normalitas Shapiro–Wilk dan paired-samples t-test dengan bantuan SPSS 25. Hasil: Hasil validasi ahli memperoleh persentase rata-rata 91,14% dengan kategori sangat valid. Respons siswa memperoleh persentase 96,67% pada uji one-to-one, 90% pada uji kelompok kecil, dan 89,33% pada uji lapangan, dengan rata-rata keseluruhan 92% berkategori sangat baik. Hasil uji Shapiro–Wilk menunjukkan nilai signifikansi 0,137 pada pretest dan 0,104 pada posttest sehingga data berdistribusi normal. Hasil paired-samples t-test menunjukkan nilai Sig. (2-tailed) = 0,000, sehingga terdapat perbedaan yang signifikan antara skor pretest dan posttest. Kesimpulan: Media interaktif berbasis teori Polya yang dikembangkan dinyatakan valid, praktis, dan efektif untuk melatih kemampuan pemecahan masalah matematika siswa sekolah dasar.
