Abstract

It is important for students to master higher order thinking skills. However, based on the results of a study from PISA in 2018, Indonesia is ranked below the OECD average. One of the reasons for the low PISA test results obtained by Indonesia is the low level of high-order thinking skills. The low level of Higher Order Thinking Ability is due to the fact that in the mathematics learning process students are only taught to memorize, rewrite and do homework or exercises, not to be trained more deeply about their Higher Order Thinking Ability and to solve problems relevant to the material being taught. The method used in this research is to use the literature review method. This study aims to determine the relevant learning methods and can improve students' higher order thinking skills. The writing method used is Literature Review, namely by reviewing previous journals that are relevant to the title and purpose of writing. From the studies that have been carried out, there are three lessons that are in line with the goals of Higher-Level Thinking Skills and can improve Higher-Level Thinking Skills, which include Scientific Learning, Problem Posing Learning Approach, and Problem-Based Learning.

Abstract

Indonesia sebagai Negara multikultural memiliki potensi besar dalam mengintegrasikan budaya lokal kedalam pembelajaran matematika melalaui pendekatan etnomatematika. Pendekatan ini tidak hanya membantu memahami konsep abstrak tetapi juga berpotensi meningkatakan aspek afektif, khususnya efisiasi diri siswa. Namun, penelitian sebelumnya lebih banyak menekankan hasil belajar komunitif, sementara kajian sistematis mengenai pengaruh etnomatematika terhadap kepercayaan diri masih terbatas dan menunjukan hasil yang beragam berdasarkan konteks dan jenjang pendidikan seperti kemampuan penalaran numerasi, kemampuan berpikir kritis, kemampuan literasi matematika, kemampuan pemecahan masalah, dan kemampuan komunikasi matematis untuk meningkatkan hasil belajar matematika. Penelitian ini bertujuan untuk mengkaji efektivitas pembelajaran matematika berbasis etnomatematika terhadap kepercayaan diri siswa melalui Systematic Literature Review (SLR) mengacu pada pedoman PRISMA 2020. Penelusuran dilakukan pada Google Scholar, DOAJ, ERIC, dan SINTA, menghasilkan 120 artikel awal. Setelah proses seleksi (penghapusan duplikasi, penyaringan judul dan abtrak, serta penilaian kelayakan), diperoleh 20 artikel yang dianalisis secara naratif. Hasil menunjukan bahwa etnomatematika secara konsisten meningkatkan kepercayaan diri dari siswa, ditandai dengan meningkatnya keyakinan diri, partisipasi aktif, dan menurunnya kecemasan matematika. Efektivitasnya bervariasi menurut jenjang pendidikan dan konteks budaya, serta lebih optimal ketika dikombinasikan dengan model pembelajaran aktif seperti Problem Based Learning dan Project Based Learning. Selain sebagai luaran, kepercayaan diri juga berperan sebagai media autor dalam peningkatan hasil belajar matematika. Temuan ini menunjukan bahwa etnomatematika tidak hanya memperkuat pemahaman konsep, tetapi juga meningkatkan aspek afektif siswa khususnya efisiasi diri melalui pembelajaran yang kontekstual dan bermakna. Kajian ini menegaskan pentingnya efisiasi diri sebagai luaran pembelajaran sekaligus mendorong integrasi budaya lokal dan pembelajaran aktif agar lebih inklusif dan memberdayakan. Dengan demikian, etnomatematika merupakan pendekatan yang relevan untuk mendukung pembelajaran matematika yang kontekstual dan berorientasi pada penguatan aspek afektif siswa.

Abstract

This study addresses the persistent challenge of fostering Higher Order Thinking Skills (HOTS) in mathematics learning, particularly in social arithmetic topics, where conventional instructional materials often fail to promote analytical and evaluative thinking. This research aims to develop and validate a student worksheet (LKPD) grounded in the Realistic Mathematics Education (RME) approach, designed to systematically support the development of HOTS through contextual problem-solving and guided reinvention processes. Employing a Research and Development (R&D) design with the ADDIE model, the study involved iterative stages of analysis, design, development, implementation, and evaluation, incorporating both qualitative feedback and quantitative assessment. The product was validated by subject matter and media experts, yielding high validity scores (3.78 and 3.54, respectively), indicating strong alignment with pedagogical and content standards. Field implementation with seventh-grade students demonstrated high practicality, reflected in a positive response rate of 93.76%. More importantly, the integration of contextual mathematical tasks facilitated students’ engagement in higher-order cognitive processes, including analysis, evaluation, and problem-solving within real-life scenarios. These findings suggest that the developed LKPD not only meets feasibility criteria but also functions as an effective pedagogical design that bridges theoretical principles of RME with HOTS-oriented instruction. This study contributes to mathematics education by offering an empirically validated instructional design that enhances cognitive engagement and supports meaningful learning in secondary education contexts.

Abstract

This study addresses the persistent challenge of students’ low conceptual understanding in geometry, particularly in triangles and quadrilaterals, which is often attributed to the dominance of procedural teaching and limited collaborative engagement. Although collaborative learning and Realistic Mathematics Education have been widely examined, their integration into structured teaching materials remains underexplored, especially in facilitating deeper conceptual understanding. This study aims to develop and evaluate collaborative learning-based teaching materials grounded in a realistic mathematics approach to enhance students’ conceptual understanding. The research employed a Research and Development design using the ADDIE model, involving analysis, design, development, implementation, and evaluation stages. The participants were seventh-grade students at SMP Negeri 4 Bajawa. Data were collected through expert validation, classroom observation, and student and teacher response questionnaires, and analyzed using descriptive and inferential approaches. The findings indicate that the developed materials achieved high validity (96% from material experts and 100% from media experts) and strong practicality (student response 100% and teacher response 92%). Furthermore, the implementation results demonstrate a substantial improvement in students’ conceptual understanding, with an average achievement categorized as highly effective. These results suggest that integrating collaborative learning with realistic mathematical contexts provides a meaningful learning experience that supports active engagement and conceptual construction. This study contributes to mathematics education by offering an empirically validated instructional design that bridges collaborative interaction and contextual learning to improve conceptual understanding.
