Abstract

This study aims to examine the effect of using student worksheets (LKPD) integrated with Nusantara ethnic culture on students’ mathematical numeracy skills through the SAVI (Somatic, Auditory, Visual, and Intellectual) learning model. This research employed a quantitative approach using a true experimental design with a Post-test Only Control Group Design. The participants were eleventh-grade students of SMA Nurul Iman Tanjung Morawa in the 2025/2026 academic year, who were randomly assigned into an experimental class and a control class. The experimental class was taught using culturally integrated LKPD through the SAVI learning model, while the control class received conventional instruction. The research instrument consisted of an essay-type mathematical numeracy test that had been validated by experts. Data were analyzed using normality tests, homogeneity tests, and an independent samples t-test at a 0.05 significance level. The results indicated that the average mathematical numeracy score of students in the experimental class was higher than that of the control class. Hypothesis testing revealed a significance value lower than 0.05, indicating a statistically significant difference between the two groups. These findings demonstrate that the use of LKPD integrated with Nusantara ethnic culture through the SAVI learning model has a positive and significant effect on improving students’ mathematical numeracy skills. Therefore, culturally integrated worksheets can serve as an effective contextual learning alternative to enhance students’ mathematical numeracy abilities.

Abstract

This study aims to analyze the effect of the RADEC (Read, Answer, Discuss, Explain, and Create) learning model based on Malay culture assisted by Canva on the mathematical numeracy abilities of eighth-grade students at SMP Negeri 25 Medan in the 2025/2026 academic year. The research method used was true experimental design with a posttest-only control group design. The research population consisted of 220 eighth-grade students, with a sample of 61 students comprising class VIII-C as the experimental group and class VIII-D as the control group. The experimental class received treatment using the RADEC model based on Malay culture with Canva media, while the control class used conventional learning. The research instrument was a mathematical numeracy ability test covering three aspects: using numbers and symbols, analyzing graphic and table forms, and interpreting decision results. Descriptive analysis results showed that the average posttest score of the experimental class was higher than the control class in every numeracy aspect. Prerequisite tests indicated that the data were normally distributed and homogeneous. Hypothesis testing using t-test yielded a t-value of 2.001 with significance less than 0.05, indicating a significant difference between the two groups. This study concludes that the RADEC learning model based on Malay culture assisted by Canva has a positive and significant effect on improving students' mathematical numeracy abilities. This model proved effective in enhancing learning outcomes across all numeracy indicators and making learning more contextual, engaging, and meaningful for students.

Abstract

Mathematical literacy skills are an essential competency of the 21st century that demands innovation in digital teaching materials. Based on the needs analysis in the field, the use of interactive, self-contained web-based learning media still requires variations and has not explicitly integrated local cultural elements in the Data Centrality Measurement material. This study aims to produce a digital learning media prototype in the form of a flipbook e-module based on Deli Malay ethnomathematics assisted by the Heyzine platform integrated with the Discovery Learning flow, and to test the theoretical feasibility of the product. This type of research is a research and development (R&D) using the 4D model. In accordance with the limitations of the initial feasibility objectives, the development procedure is limited to the Develop stage in the theoretical validity testing phase by experts. Data collection techniques are carried out through documentation studies, structured interviews with teachers, and distribution of Likert scale assessment questionnaire instruments to experts. The assessment data are then analyzed quantitatively using the Aiken's V agreement index formula. The results of the development stage research indicate that the accumulated average content validity index of all learning device instruments is 0.92 with the criteria of Very Valid. In detail, the validity values were obtained from the Teaching Module instrument (0.88), LKPD (0.90), material aspects (0.91), flipbook media (0.94), cultural context (0.92), and the mathematical literacy ability test instrument which achieved the highest coefficient of 0.96. The conclusion of the study confirms that this ethnomathematics-based flipbook e-module product is declared valid, theoretically feasible, and recommended as a variation of independent teaching materials to support the achievement of 21st-century competency mathematics learning.

Abstract

This study aims to develop a Missouri Mathematics Project (MMP) learning model based on Malay culture with the assistance of the educational game Wordwall to improve junior high school students’ numeracy skills. The research employed a Research and Development (R&D) method using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The research subjects were 40 eighth-grade students of SMP Swasta Al Washliyah 8 Medan. The results showed that the developed MMP model based on Malay culture was valid, practical, and effective in enhancing students’ numeracy abilities. The model’s validity, obtained through validation by material experts, media experts, and cultural experts, reached an average of 96.6% (very valid category). The practicality of the model, assessed by teachers and students, achieved an average score of 88.6% (very practical category).

Abstract

Technological developments require teachers to integrate interactive digital media to improve the quality of 21st-century learning. However, early observations at SMP Negeri 3 Tanjung Beringin showed that the utilization of web-based learning media was not optimal despite the availability of supporting facilities. This community service activity aims to introduce the Wordwall platform as an interactive learning media solution and to enhance teachers’ pedagogical competence in operating its features. The implementation method uses a learning-by-doing approach, which includes the preparation stage, workshops through lectures and demonstrations, independent practice in content creation, and evaluation. The results show a significant increase in teachers’ understanding and technical skills in developing digital learning media. Teachers were able to explore quiz features, games, and even printable formats (PDF) to overcome network constraints. In conclusion, this activity successfully narrowed the digital literacy gap and increased teacher motivation to create a more dynamic and student-centered learning environment at SMP Negeri 3 Tanjung Beringin.
