Abstract

Mathematics learning achievement reflects students’ ability to understand and apply concepts; however, in reality, many students have not yet reached optimal results. This condition emphasizes the importance of considering internal factors that influence academic performance, one of which is self-regulated learning (SRL), defined as students’ ability to plan, monitor, and evaluate their learning process independently. This study aims to examine the relationship between SRL and students’ mathematics learning achievement. The method used is quantitative with an ex-post facto design. The population consisted of all seventh-grade students of SMPN 4 Klari in the 2024/2025 academic year, with a sample of 87 students selected using simple random sampling. The research instruments were an SRL scale and mathematics midterm exam scores, while data analysis was conducted using Spearman’s rank correlation test. The results showed a correlation coefficient (rs) of 0.308 with a significance level of 0.004 , indicating a significant positive (direct) relationship between SRL and mathematics learning achievement with a weak correlation. The results demonstrate that the higher the students’ SRL, the better their mathematics learning achievement. Prestasi belajar matematika mencerminkan kemampuan siswa dalam memahami dan menerapkan konsep, namun kenyataannya masih banyak siswa yang belum mencapai hasil optimal. Kondisi ini menegaskan pentingnya memperhatikan faktor internal yang memengaruhi capaian akademik, salah satunya adalah self-regulated learning (SRL), yaitu kemampuan siswa dalam merencanakan, memantau, dan mengevaluasi proses belajar secara mandiri. Penelitian ini bertujuan untuk mengkaji hubungan antara SRL dan prestasi belajar matematika siswa. Metode yang digunakan adalah kuantitatif dengan desain ex-post facto. Populasi penelitian mencakup seluruh siswa kelas VII SMPN 4 Klari Tahun Ajaran 2024/2025, dengan sampel sebanyak 87 siswa yang dipilih melalui teknik simple random sampling. Instrumen penelitian berupa skala SRL dan nilai UTS matematika, sedangkan analisis data dilakukan menggunakan uji korelasi rank Spearman rho. Hasil penelitian menunjukkan koefisien korelasi (rs) sebesar 0,308 dengan taraf signifikansi 0,004 , yang menunjukkan adanya hubungan positif (searah) yang signifikan antara SRL dan prestasi belajar matematika dengan tingkat hubungan yang lemah. Hasil penelitian menunjukkan bahwa semakin tinggi tingkat SRL siswa, maka semakin baik prestasi belajar matematika yang dicapai.

Abstract

Mathematical communication skills are fundamental competencies that students must have, but there are no valid and reliable test instruments to measure the mathematical communication skills of Madrasah Ibtidaiyah students specifically. This research aims to develop valid, reliable, and practical mathematical communication ability test instruments for Madrasah Ibtidaiyah students. The research uses a Research and Development (R&D) approach with the Plomp model which includes the initial investigation, prototype phase, and assessment phase. The research subjects consisted of 39 students of class V MIN 1 Cilegon City who were selected using the purposive sampling technique. The instrument was developed based on the theoretical framework of NCTM with four mathematical communication indicators in KPK and FPB materials. The developed instrument met psychometric standards with very high construct validity (correlation coefficient r > 0.80 for all question items) and high reliability (α = 0.861). The distribution of difficulty level showed one question item in the medium category (65.40%) and three questions in the very difficult category (15.90%-17.80%). The differentiating power showed that one question item was categorized as sufficient (0.341) while the other three items needed improvement. The instrument was successfully developed with adequate psychometric quality and can be used as an evaluation tool for mathematical communication skills at Madrasah Ibtidaiyah. Further research is suggested to expand the research sample and develop instruments for other mathematical materials. Kemampuan komunikasi matematika merupakan kompetensi mendasar yang harus dimiliki siswa, namun tidak ada instrumen tes yang valid dan handal yang tersedia untuk secara khusus mengukur kemampuan komunikasi matematika siswa Madrasah Ibtidaiyah. Penelitian ini bertujuan untuk mengembangkan instrumen uji kemampuan komunikasi matematika yang valid, handal, dan praktis bagi siswa Madrasah Ibtidaiyah. Penelitian menggunakan pendekatan Research and Development (R&D) dengan model Plomp yang terdiri dari penelitian pendahuluan, fase pembuatan prototipe, dan fase penilaian. Subjek penelitian terdiri dari 39 siswa kelas lima MIN 1 Cilegon City yang dipilih menggunakan teknik purposive sampling. Instrumen ini dikembangkan berdasarkan kerangka teoritis NCTM dengan empat indikator komunikasi matematis pada materi KPK dan GCD. Instrumen yang dikembangkan memenuhi standar psikometri dengan validitas konstruksi yang sangat tinggi (koefisien korelasi r > 0,80 untuk semua item) dan keandalan tinggi (α = 0,861). Distribusi tingkat kesulitan menunjukkan satu item dalam kategori sedang (65,40%) dan tiga item dalam kategori sangat sulit (15,90%-17,80%). Kekuatan diskriminasi menunjukkan satu item dalam kategori yang memadai (0,341) sementara tiga lainnya membutuhkan perbaikan. Instrumen ini berhasil dikembangkan dengan kualitas psikometrik yang memadai dan dapat digunakan sebagai alat evaluasi kemampuan komunikasi matematika di Madrasah Ibtidaiyah.
