Abstract

Differentiation is a popular approach today, especially with the implementation of the independent curriculum. This approach can improve students' cognitive abilities without forcing them to learn in ways that are not essential. The purpose of this study is to identify how differentiation is implemented and evaluate its effectiveness in mathematics learning, as well as to explain the challenges teachers face in applying this approach. The method used was Sistematic Literatur Review (SLR) related to differentiated learning to increase student interest and learning outcomes. The data sources used were 32 articles published in the last three years. The results showed that learning using a differentiated approach had a significant impact on students' cognitive abilities, as indicated by their interest, activity, and learning outcomes. During implementation, there are several things that teachers must pay attention to, namely that teachers must design learning activities as effectively as possible and conduct diagnostic assessments at the beginning of the activity. Challenges in implementing differentiated learning also exist, namely time, managing thoughts and bodies in providing guidance to students, preparing adequate learning resources and media for all learning styles of each student, and teachers must be open to developments

Abstract

Model pembelajaran RADEC (Read, Answer, Discuss, Explain, Create) merupakan salah satu inovasi yang bertujuan untuk menciptakan proses pembelajaran yang aktif, kolaboratif, dan kontekstual. Tujuan penelitian ini adalah untuk mengkaji bagaimana penerapan dan efektivitas model RADEC dalam meningkatkan hasil belajar siswa. Metode yang digunakan adalah Systematic Literature Review (SLR). Data yang digunakan berupa data sekunder yang berasal dari 18 artikel terindeks Sinta melalui Google Scholar yang dipublikasikan berkisar antara tahun 2019 hingga 2025. Prosedur penghimpunan data penelitian literatur review ini dengan berdasarkan kriteria tertentu. Adapun hasil tinjauan menunjukkan bahwa model RADEC umumnya diterapkan pada semua jenjang pendidikan dengan menyesuaikan karakteristik siswa dan topik pembelajaran. Tahap Read dan Answer dimanfaatkan untuk membangun pemahaman awal dan kesiapan siswa, sementara tahap Discuss dan Explain menumbuhkan kemampuan komunikasi, berpikir kritis, dan kerja sama. Adapun tahap Create memberikan kesempatan bagi siswa untuk mengembangkan kreativitas melalui produk pembelajaran yang beragam. Berdasarkan temuan yang dianalisis, model ini efektif dalam meningkatkan kemampuan berpikir tingkat tinggi (HOTS), literasi numerasi, serta motivasi dan partisipasi aktif siswa dalam proses pembelajaran. Ketercapaian tujuan pembelajaran juga lebih optimal karena keterlibatan aktif siswa selama proses pembelajaran berlangsung. Meski demikian, masih terdapat keterbatasan dalam cakupan topik kajian dan eksplorasi aspek afektif siswa. Oleh karena itu, penelitian lanjutan disarankan untuk menggunakan pendekatan kuantitatif atau longitudinal agar diperoleh gambaran lebih mendalam mengenai dampak model RADEC secara menyeluruh. Dengan panduan implementasi yang sistematis dan dukungan empiris yang kuat, model RADEC berpotensi menjadi model pembelajaran yang adaptif, relevan, dan berdampak positif terhadap hasil belajar siswa.

Abstract

This study was motivated by the low level of critical thinking skills among junior high school students in solving mathematical word probleims, as evident from previous studies and the researcher's initial observations in the field. This study aims to describe the profil of junior high school students' errors in solving mathematical story problems in terms of critical thinking skills. The method used is qualitative descriptive with 32 seventh-grade students as subjects at a public junior high school in South Tambun in the 2024/2025 academic year. The research instrument was an essay test containing five story problems developed based on critical thinking ability indicators, including providing simple explanations, providing further explanations, determining strategies and techniquies, and drawing conclusions. The data were analyzed through the stages of reduction, presentation, and conclusion drawing. The results showed that most students were in the low critical thinking ability category (63%) and the rest were in the moderate category (37%), while no students reached the high category. Students with low critical thinking abilities tended to make mistakes in almost all indicators, while students with moderate abilities were able to meet most of the indicators but were not consistent, especially in determining solution strategieis and drawing conclusions. These findings indicate that the main weakness of students lies in the aspects of strategy planning and drawing conclusions, so mathematics learning that emphasizes the development of critical thinking skills through non- routine story problems and the use of targeted assessment rubrics is needed.
