Abstract

Penelitian ini bertujuan untuk mengembangkan instrumen diagnostik three tier test untuk mengetahui miskonsepsi siswa pada materi statistika. Latar belakang penelitian ini adalah banyaknya siswa yang mengalami miskonsepsi, terutama dalam menentukan mean, median, dan modus, yang mempengaruhi kualitas pembelajaran. Penelitian ini menggunakan metode Penelitian dan Pengembangan (R&D) dengan model 4-D yang terdiri dari tahapan define, design, and development, tanpa tahapan disseminattion karena keterbatasan waktu dan ruang lingkup. Keunggulan penelitian ini terletak pada penggunaan penalaran terbuka pada tingkat kedua, yang memungkinkan peneliti untuk menggali lebih dalam pemikiran siswa dibandingkan dengan penelitian sebelumnya yang menggunakan penalaran tertutup. Alat yang dikembangkan telah divalidasi oleh ahli dan di uji kepraktisannya oleh guru dan siswa. Hasil validasi menunjukkan tingkat validitas yang sangat valid sebesar 90%, dan kepraktisan mencapai rata-rata 87,5%. Dari hasil uji coba awal, ditemukan bahwa siswa mengalami 8,4% miskonsepsi, 23,3% miskonsepsi false positive, dan 12,4% miskonsepsi false negative. Berdasarkan hasil ini, dapat disimpulkan bahwa instrumen ini efektif dalam mengidentifikasi miskonsepsi siswa dan dapat menjadi solusi alternatif bagi guru dalam meningkatkan pembelajaran berbasis pemahaman konsep.

Abstract

This study aimed to develop the educational game "Algebra Explorer: The SPLDV Saga" and to examine its effectiveness in improving junior high school students' problem-solving ability and learning interest. The study employed the Research and Development (R&D) method following the Borg and Gall model, comprising seven stages: identification of potential and problems, data collection, product design, design validation, product revision, product trial, and evaluation. The subjects were 28 eighth-grade students. The instruments consisted of a problem-solving ability test, a learning interest questionnaire, and a student response questionnaire. Validation results from subject-matter experts (87.47%) and media experts (90.91%) indicated that the product was highly valid and suitable for use. The mean problem-solving score increased from 63.57 to 82.38, and the paired samples t-test yielded a Sig. (2-tailed) value of 0.000 < 0.05, indicating a significant difference between pretest and posttest scores. The N-Gain value of 0.52 (moderate category) demonstrated that the game was effective in improving students' mathematical problem-solving ability, while student responses reached an average of 85.71% (very good category). Therefore, the educational game "Algebra Explorer: The SPLDV Saga" is effective in enhancing students' problem-solving ability and learning interest, and it received highly positive feedback.

Abstract

This study aimed to compare the effectiveness of the Teaching at the Right Level (TaRL) approach and conventional learning on the mathematical conceptual understanding ability of seventh-grade students at SMP Negeri 13 Pontianak in the topic of data presentation. This research employed a Quasi-Experimental Design using the Nonequivalent Control Group Design. The sample was selected through purposive sampling, consisting of Class VIIA as the experimental group (32 students), which received the Teaching at the Right Level (TaRL) approach, and Class VIIC as the control group (32 students), which received conventional learning. The research instrument was a test of mathematical conceptual understanding on data presentation material. Data were analyzed using the independent samples t-test. The results showed that both learning approaches improved students’ conceptual understanding abilities. The experimental group’s mean score increased from 31.01 to 80.08, with an average of 49.07, while the control group’s mean score increased from 30.08 to 69.73, with an average of 39.65. The independent samples t-test revealed that t_calculated = 8.1057 was greater than t_table = 1.9990 (α = 0.05), indicating that the mathematical conceptual understanding ability of students taught using the Teaching at the Right Level (TaRL) approach was significantly better than that of students taught through conventional learning. The TaRL approach enables students to learn according to their individual ability levels, thereby facilitating a better understanding of mathematical concepts.

Abstract

Perkembangan pesat artificial intelligence (AI) menuntut guru untuk meningkatkan kemampuan literasi digital, terutama pada tahap abstraksi saat menelaah sumber pustaka sebagai dasar penyusunan perangkat kurikulum dan pembelajaran. Permasalahan yang dihadapi mitra (guru SMK Koperasi Pontianak) adalah belum optimalnya pemanfaatan AI sebagai alat bantu penguatan kompetensi abstraksi dalam proses literasi untuk menyusun perangkat kurikulum utama SMK, perangkat perencanaan pembelajaran, dan perangkat pendukung khusus SMK. Kegiatan pengabdian ini menerapkan metode pelatihan dan pendampingan dengan tahapan: pengenalan, penyampaian materi dan tanya jawab, serta praktik terarah dan pendampingan kelompok dalam penggunaan AI untuk menyusun bahan ajar abstrak, dan membuat soal. Kegiatan dilaksanakan pada 15 Desember 2025 dengan peserta 20 guru; hasil evaluasi angket menunjukkan respon sangat positif, dengan simpulan kepuasan peserta sebesar 99,24% dan mayoritas peserta menyatakan materi sesuai kebutuhan serta mudah dipahami. Dengan demikian, pelatihan berbantuan AI efektif memperkuat kompetensi abstraksi pada proses literasi guru dan berpotensi mendukung peningkatan kualitas penyusunan perangkat pembelajaran secara lebih efisien; tindak lanjut pendampingan disarankan agar implementasi berkelanjutan.
