Jurnal Eduscience is a peer-reviewed journal that is published by LPPM of Labuhanbatu University. This journal publishes biannually in June and December. This Journal publishes current original research on education studies using an interdisciplinary perspective, especially within Mathematic Education, Biology Education, Civic Education, Science Education, Physics Education, and all about teaching and learning research. Reviewers will review any submitted paper. The review process employs a double-blind review, which means that both the reviewer and author identities are concealed from the reviewers, and vice versa

Abstract

Purpose – This study aims to examine the effectiveness of product-based learning with upcycled materials in improving elementary school students’ mathematics learning outcomes on bar chart material.Methodology – The study employed a classroom-based, iterative research design implemented across several learning phases to optimize the learning process and outcomes. The participants were 37 fourth-grade students with heterogeneous academic abilities. We collected data through learning outcome tests, observations, and documentation, and analyzed them using quantitative and qualitative approaches.Findings – The results showed a significant increase in student learning outcomes. The average score increased from 63.8 in the initial phase to 72.4, then to 84.1 in the final phase. The percentage of learning completion also increased from 37.8% to 62.2%, then to 89.2%, exceeding the established learning effectiveness criteria. The findings indicate that integrating product-based learning with upcycled materials improves learning outcomes and strengthens students' conceptual understanding through active, contextual, and meaningful learning activities. Students’ active involvement supported by concrete media enabled deeper knowledge construction and reinforced the constructivist learning approach.Contribution – This study contributes to the development of innovative mathematics learning by integrating product-based learning with environmentally based learning media, providing an alternative contextual learning approach that supports student engagement, creativity, and environmental awareness in elementary education.

Abstract

Purpose –This study aimed to develop and examine the validity and reliability of pedagogical adaptability and contextual digital learning development instruments for senior high school teachers in the NKRI-RDTL border area.Methodology – This study employed a quantitative approach using an instrument development research design. The study involved 64 senior high school teachers and four expert validators. Instrument development was carried out through the stages of theoretical construct development, indicator and item blueprint formulation, expert validation, instrument revision, field testing and validity and reliability analysis. Content validity was analyzed using Aiken’s V, empirical validity was analyzed using Pearson Product-Moment correlation, and instrument reliability was analyzed using Cronbach’s Alpha.Findings – The findings showed that the developed instruments had high content validity, with Aiken’s V values ranging from 0.88 to 1.00. The empirical validity test showed that most statement items were valid, while the reliability of both instruments was categorized as high to very high. These findings indicate that the developed instruments are appropriate for measuring pedagogical adaptability and contextual digital learning development in border areas.Contribution – The novelty of this study lies in the development of instruments designed based on the characteristics of learning in border areas, particularly in relation to the demands of adaptive and contextual digital learning. The developed instruments can be used as assessment tools to map teachers’ personal capacities more accurately and to support teacher competency development programs in border areas.
