Abstract

Misconceptions in integer operations remain a common challenge among junior high school students, affecting their understanding of mathematical concepts and procedures. This study aimed to remediate these misconceptions through a role-playing approach that integrates physical and contextual learning experiences. The participants were five seventh-grade students from a junior high school in West Kalimantan, Indonesia, selected based on diagnostic test results and teacher recommendations. A descriptive qualitative design was employed, with data collected through tests, observations, interviews, and documentation. The remediation process was carried out in four systematic stages involving role simulation with physical number lines, group discussions, contextual problem-solving, and reflection. The findings revealed that students successfully overcame conceptual, procedural, and operational misconceptions, while representational misconceptions decreased considerably though still persisted in some students. Role-playing proved effective in fostering engagement and conceptual reconstruction, indicating its potential as an alternative strategy for misconception remediation. Further enhancement of visualization tools, such as number line media or digital supports, is recommended to optimize learning outcomes.

Abstract

Background: Environmental sustainability and values-oriented mathematics education have gained increasing scholarly attention, yet their conceptual and intellectual connections remain insufficiently mapped. Aims: This study aimed to compare the knowledge structures of these research domains, assess their observable convergence, and formulate an integrative agenda for sustainable mathematics learning. Method: A comparative bibliometric analysis was conducted using English-language Scopus records published between 2005 and 2026. The analysis included mathematics × environment (n = 209) and mathematics × values/ethnomathematics (n = 362) corpora, with an environment × values corpus (n = 3,853) serving as a contextual benchmark. Publication performance, geographical distribution, journals, co-authorship, keyword co-occurrence, co-citation, and bibliographic coupling were examined. Results: Limited convergence was identified. Only three records emerged from the direct three-block search, while four overlap candidates were found among 567 deduplicated focal records (0.71%). The environmental corpus centered on sustainability, climate, and modelling, whereas the values corpus emphasized ethnomathematics, culture, local wisdom, and character. Conclusion: The findings demonstrate distinct yet potentially complementary knowledge structures. The proposed ESME-V framework connects cognitive-ecological literacy, affective-ethical engagement, and spiritual-cultural grounding as a testable framework for advancing sustainable mathematics learning.
