Abstract

This research aims to develop the GAULL (Wordwall Educational Game) Puzzle Application, based on the local culture of Woe Are "PEO–HEDA", as an educational medium that can improve early childhood social skills. The study's background reveals that children's social skills, particularly in terms of cooperation, empathy, communication, and conflict resolution, remain relatively low. In fact, these social values are the foundation of children's social development, and interaction through collaborative play can accelerate the development of social cooperation. This research employs the R&D method, utilising the ADDIE model, which encompasses the stages of analysis, design, development, implementation, and evaluation. The subjects of the study were 22 children aged 5–6 years at Satap SDK Olabolo Kindergarten, Golewa District, Ngada Regency. Application development is carried out using the Wordwall platform, which incorporates puzzle games to support contextual learning. The results of the material expert's validation gave a score of 32 (in the very feasible category), while the media expert and design expert gave scores of 40.5, which also indicate very high feasibility. These results suggest that GAULL fulfils the technical and pedagogical aspects as a learning medium that is in accordance with the characteristics of early childhood social development. Findings in the field show that the use of GAULL has a positive impact on improving children's social skills. Children exhibit more active interaction when sharing, participating in group tasks, and demonstrating empathy and cooperation while using the GAULL application.

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.

Abstract

This study aims to systematically examine how and under what conditions ethnomathematical approaches contribute to the development of students’ numeracy skills in mathematics education. Although ethnomathematics has been widely studied, there remains a lack of systematic synthesis focusing specifically on its impact on numeracy outcomes within diverse instructional contexts. This study adopts a Systematic Literature Review (SLR) approach guided by the PRISMA 2020 framework to ensure methodological transparency and rigor. Relevant studies were identified from multiple academic databases, including Google Scholar, Semantic Scholar, Crossref, SINTA, and DOAJ, supported by the Publish or Perish tool. Through a structured selection  process involving identification, screening, eligibility assessment, and inclusion, 20 peer-reviewed articles were analyzed based on predefined criteria. The findings reveal that ethnomathematical approaches can enhance students’ numeracy by embedding mathematical concepts within culturally meaningful contexts, thereby strengthening conceptual understanding and problem-solving abilities. However, the effectiveness of this approach is not uniform and is strongly influenced by instructional design, the authenticity of cultural integration, and teacher pedagogical competence. This study contributes to the field by clarifying the conditions under which ethnomathematics supports numeracy development and by offering a more nuanced understanding beyond general effectiveness claims. The findings provide a foundation for developing culturally responsive numeracy instruction and suggest directions for future research, particularly in terms of experimental validation and cross-contextual analysis.
