Abstract

Despite high cognitive potential from fish consumption, coastal students face boring traditional modules; thus, a culture-based RME-AI module was developed to enhance numeracy skills. This study aims to analyze the level of validity, practicality, and effectiveness of the Realistic Mathematics Education (RME) learning module based on coastal culture with the Gemini application and how the module can improve the numeracy literacy skills of fifth grade students. The RME module development leverages students' environmental reality to facilitate mathematical learning, effectively bridging pedagogical gaps to achieve superior educational goals through contextual experiences and meaningful conceptual mastery. So that with this module it can help students in improving numeracy literacy skills. The RME-based module is said to be suitable for use if it meets three criteria: valid, practical, and effective. Based on the results of the research analysis, 1) the module was declared very valid after being revised with a percentage of 89.00%, 2) the module was declared practical with an average student response questionnaire result of 84.00% in the field test. Furthermore, 3) the normalized gain test was used to determine how effective the RME learning module was in improving students' numeracy literacy skills. The gain test results showed a value of 0.35 which indicates moderate. This means that the RME learning module based on coastal culture is effective in improving students' numeracy literacy skills. The implications suggest integrating local wisdom bridges abstract-reality gaps, while Gemini AI offers scalable, culturally-responsive models that significantly enhance student engagement and long-term retention of numeracy skills.

Abstract

Probability theory is inherently abstract and structurally complex, often creating substantial cognitive barriers for students when solving problems. This study aims to formulate a genetic decomposition of core probability concepts based on the mental structures constructed by undergraduate learners. Guided by the APOS (Action–Process–Object–Schema) theoretical framework, the research employed a three-phase methodological cycle: (1) epistemological analysis of fundamental probability concepts, (2) design and administration of diagnostic and instructional instruments, and (3) analysis and validation of students’ cognitive structures. The study was conducted at two universities in Central Java, Indonesia, involving four mathematics education undergraduates enrolled in an introductory probability course. Data were collected through content analysis, domain-specific assessment instruments, and semi-structured interviews. The APOS framework was used to trace students’ mental constructions in relation to classical probability, independence, conditional probability, total probability, and Bayes’ theorem. The results reveal that students had not fully internalized the mental objects and schemas required to coordinate these concepts during problem-solving activities. Their reasoning remained largely at the process level, particularly in representing sample spaces, applying counting techniques, and thematizing probability structures. Nonetheless, several elements of their cognitive behavior aligned with the refined genetic decomposition. The findings highlight the necessity of strengthening students’ APOS-based mental constructions to support the development of coherent probabilistic schemas and enhance conceptual as well as procedural fluency.

Abstract

AbstractThe main problem in elementary school mathematics learning is the low student motivation and learning outcomes caused by conventional approaches that tend to be abstract and lack connections to real-life contexts. This study aims to develop an educational game based on Realistic Mathematics Education (RME) with the integration of Acehnese local wisdom to improve students’ motivation and learning outcomes. The research employed a modified Research and Development (R&D) model of Borg & Gall, which consisted of needs analysis, design, expert validation, limited trial, revision, main field trial, and final revision. The research subjects included 30 fifth-grade students in the limited trial stage and 90 students from three different elementary schools in the main field trial, using a quasi-experimental design with a pretest-posttest control group. The instruments used were student response questionnaires, expert validation sheets, and achievement tests. Expert validation results indicated that the product was in the “highly valid” category. The limited trial showed that 90% of students considered the game easy to use and 85% felt more motivated, with learning achievement increasing from an average pretest score of 62 to 78 in the posttest; a paired-sample t-test yielded t(29) = 5.84, p < 0.001. The main field trial demonstrated a significant improvement, where the experimental class increased from an average score of 61 to 84, while the control class only increased from 63 to 72; the ANOVA results showed F(1,88) = 12.35, p < 0.01 with an effect size of 0.82 (large category). It is concluded that the RME-based educational game with Acehnese local wisdom is effective in enhancing students’ motivation and learning outcomes, and it has the potential to be further developed by adding adaptive and interactive features to strengthen student engagement.Keywords: Deep Learning; Game; Local Wisdom; RME Abstrak Permasalahan utama dalam pembelajaran matematika di sekolah dasar adalah rendahnya motivasi dan hasil belajar siswa akibat pendekatan konvensional yang cenderung abstrak serta minim keterkaitan dengan konteks nyata kehidupan sehari-hari.

Abstract

Numeracy skills are among those that need to be developed in the 21st century, so they are often a topic in educational research. Furthermore, the character of critical reasoning is a frequently discussed topic because it is part of the Pancasila student profile dimension. However, based on the results of the 2024 education report card in Melawi Regency, numeracy skills and critical reasoning character are still low. Therefore, efforts are needed to improve students' numeracy skills and critical reasoning character through the use of RME (Realistic Mathematics Education)-based ethnomathematics modules. The purpose of this study was to determine the effectiveness of the RME-based ethnomathematics module of the Dayak Muntak tribe in improving students' numeracy skills and critical reasoning character. This research used an experimental design with a pretest-posttest control group. The subjects of this study were 56 students from the control class and 57 from the experimental class. This research instrument used numeracy test questions and a critical reasoning character questionnaire. The results of the study indicate that implementing the RME-based ethnomathematics module had a significant and effective impact on students' numeracy and critical reasoning skills. This is evident from the results of the Mann-Whitney U-test, which demonstrated a treatment effect, and the N-Gain test, which indicated the level of improvement in numeracy and critical reasoning skills.Kemampuan numerasi merupakan satu diantara kemampuan yang perlu dikambangkan pada abad XXI, sehingga sering menjadi topik dalam penelitian pendidikan. Selain itu, topik yang sering dibahas adalah karakter bernalar kritis karena merupakan bagian dari dimensi profil pelajar Pancasila. Namun, berdasarkan hasil rapor pendidikan tahun 2024 di Kabupaten Melawi kemampuan numerasi dan karakter bernalar kiritis masih rendah. Oleh karena itu, perlu upaya untuk meningkatkan kemampuan numerasi dan karakter bernalar kritis siswa melalui penggunaan modul etnomatematika berbasis RME (Realistic Mathematics Education). Tujuan penelitian ini adalah mengetahui efektivitas  modul etnomatematika suku Dayak Muntak berbasis RME untuk meningkatkan kemampuan numerasi dan karakter bernalar kritis siswa. Metode penelitian ini menggunakan metode eksperimen dengan desain pretest-posttest control group. Subjek penelitian ini terdiri dari 56 siswa dari kelas kontrol dan 57 siswa dari kelas eksperimen. Instrumen penelitian ini menggunakan soal tes numerasi dan angket karakter bernalar kritis. Hasil penelitian menunjukkan bahwa penerapan modul etnomatematika berbasis RME memberikan pengaruh yang signifikan serta efektif dalam meningkatkan kemampuan numerasi dan karakter bernalar kritis peserta didik.

Abstract

Kemampuan numerasi siswa sekolah menengah di Indonesia menunjukkan kesenjangan yang jelas antara penguasaan soal rutin dan kemampuan menalar, menafsirkan data, serta memahami konteks. Kondisi ini menuntut pemetaan yang lebih komprehensif untuk memahami variasi capaian numerasi berdasarkan domain, level kognitif, dan karakteristik asesmen. Penelitian ini bertujuan memetakan kompetensi numerasi siswa SMA dan SMK di Provinsi Riau serta mengidentifikasi faktor pembelajaran, strategi guru, dan karakteristik soal yang memengaruhi hasil tersebut. Metode yang digunakan adalah mixed methods dengan desain sekuensial eksplanatori, melibatkan tes kuantitatif pada 288 siswa dan wawancara mendalam dengan guru serta siswa dari dua sekolah berprestasi tinggi. Instrumen tes mencakup 30 soal numerasi yang merepresentasikan tiga domain (geometri & pengukuran, aljabar, data & ketidakpastian), tiga level kognitif (Knowing, Applying, Reasoning), dan enam jenis soal. Hasil penelitian menunjukkan pola capaian hierarkis yang menurun dari Knowing ke Reasoning dengan perbedaan signifikan antar domain dan jenis soal. Capaian terendah ditemukan pada domain data dan ketidakpastian serta soal uraian yang menuntut penalaran tingkat tinggi dan interpretasi teks panjang. Temuan kualitatif menegaskan bahwa kesulitan utama siswa berkaitan dengan beban kognitif saat membaca konteks, keterbatasan hubungan konseptual–prosedural, dan kurangnya pembelajaran berbasis situasi nyata. Penelitian ini menyimpulkan bahwa peningkatan numerasi memerlukan pendekatan pembelajaran yang mengintegrasikan literasi membaca, penalaran matematis, dan strategi pedagogis reflektif secara berkelanjutan.

Abstract

Kemampuan berpikir kritis matematis siswa SMP masih tergolong rendah akibat keterbatasan bahan ajar yang interaktif dan kontekstual. Penelitian ini bertujuan mengembangkan E-LKPD berbasis RME terintegrasi GeoGebra serta menguji efektivitasnya. Metode yang digunakan adalah R&D dengan model Plomp yang disederhanakan, melibatkan siswa kelas VIII SMP Negeri 2 Haurgeulis Indramayu. Instrumen penelitian terdiri atas lembar validasi ahli, angket respons siswa, dan tes berpikir kritis. Hasil penelitian menunjukkan bahwa E-LKPD dinyatakan sangat valid (ahli materi 86,40%; ahli media 87%), sangat praktis (respons siswa 88%), dan efektif berdasarkan uji statistik yang menunjukkan perbedaan signifikan antara pretest dan posttest (sig. < 0,05). Dengan demikian, E-LKPD berbasis RME berbantuan GeoGebra terbukti valid, praktis, dan efektif sebagai inovasi pembelajaran matematika yang kontekstual, interaktif, dan berorientasi HOTS. Penelitian ini merekomendasikan penggunaan E-LKPD tersebut secara lebih luas di SMP. The deficiency of interactive and contextual resources has contributed to the subpar mathematical critical thinking skills observed among junior high schoolers. To address this, the current study developed and evaluated an RME-based Electronic Student Worksheet (E-LKPD) integrated with GeoGebra. Utilizing a simplified Plomp R&D model at SMP Negeri 2 Haurgeulis, the research utilized expert validations, questionnaires, and specialized tests for data collection. Findings indicate that the E-LKPD is highly valid (scoring over 86%), remarkably practical (88%), and statistically effective (sig. < 0.05) in improving student outcomes. Consequently, this GeoGebra-assisted tool serves as a robust innovation for HOTS-oriented learning and is recommended for broader academic implementation
