Abstract

This study is a Systematic Literature Review (SLR) aimed at analyzing the need for developing Smart Digital Learning (SDL) based on PISA-oriented problems and local wisdom to enhance junior high school students’ numeracy literacy. The review covers national and international articles relevant to SDL, mathematical literacy, Problem-Based Learning (PBL), and ethnomathematics. A total of 20635 articles were initially identified from Scopus, ERIC, Google Scholar, and Garuda databases, and through a systematic screening process, 30 studies published between 2020–2025 were selected for in-depth analysis. The reviewed literature covers topics on SDL, mathematical literacy, Problem-Based Learning (PBL), and ethnomathematics. The findings indicate that the use of digital technologies such as games and Augmented Reality effectively improves students’ motivation, problem-solving, and metacognitive abilities. In addition, the integration of PBL and local wisdom contexts strengthens students’ mathematical communication and reasoning skills. However, the literature review also reveals that studies integrating PISA, PBL, and local wisdom within a unified digital learning system remain limited. Therefore, it is necessary to develop a direction for Smart Digital Learning that not only emphasizes technological aspects but also contextualizes mathematics learning through PISA problems and cultural values. The results of this study recommend the design of SDL as an innovative learning solution capable of balancing global standards with local contexts, thereby enhancing students’ numeracy literacy in a meaningful and sustainable manner.

Abstract

This study analyzes the application of ethnomathematics in Fort Rotterdam, Makassar, focusing on the use of numbers and measurements in architecture as symbolic representations and defense strategies. The research employed direct observation, semi-structured interviews with tour guides, and literature review of supporting documents and journals. The findings indicate that numbers are utilized in various mathematical activities, including counting the number of bastions, gates, and internal buildings; measuring the length, area, height, and wall thickness; and designing structures that serve both strategic functions and cultural meanings. Notably, the five bastions were designed to resemble a turtle, reflecting the Gowa Kingdom’s philosophy of ruling over both land and sea. The implications of these findings are significant for mathematics education, as integrating local cultural contexts and symbolism into learning can enhance conceptual understanding, problem-solving skills, learning motivation, and students’ cultural identity. The study underscores that cultural heritage sites such as Fort Rotterdam are not merely historical artifacts but also serve as contextual mathematics learning resources that enrich formal educational experiences.

Abstract

This study introduces the Coefficient Parallelisator Matrix (CPM) as a novel diagonal similarity operator designed to preserve structural and semantic symmetry within the framework of Knot Semantic Logic (KSL). The CPM formalizes the process of parallelization in linguistic and conceptual structures by transforming semantic matrices through similarity operations that maintain eigenvalues, determinants, and symmetry invariants. Each element of the CPM acts as a scaling coefficient, re- balancing semantic weights while conserving the overall interpretive equilibrium of the text. Mathematically, the transformation A′ = MAM−1 establishes a spectral equivalence between the original and parallelized structures, ensuring that both share identical eigen-spectra, determinant, and Hermitian invariants. This invariance reflects a form of semantic gauge symmetry, wherein the un- derlying topology of meaning remains stable despite local transformations in semantic intensity. Conceptually, the operator bridges linguistic theory, topology, and algebraic representation, providing a formal mechanism for analyzing reflective relations such as parallelism, chiasmus, and concentric composition. The findings extend the mathematical foundation of KSL by establishing the Coefficient Parallelisator as an analytical framework for quantifying semantic symmetry—enabling deeper integration between mathematical logic, structural linguistics, and computational semantics.

Abstract

Discrete Mathematics learning at the university level requires high-level reasoning skills and deep conceptual understanding, particularly in the topic of recursive relations. However, in instructional practice, students still experience various learning difficulties that affect the quality of their understanding. This study aims to identify students’ learning obstacles in recursive relations as a preliminary study within the framework of Didactical Design Research (DDR). A qualitative approach was employed by analyzing students’ responses to true–false items accompanied by written justifications administered in a final examination. The data were analyzed to identify learning obstacles based on ontogenic and epistemological perspectives. The findings indicate that students experience learning obstacles characterized by the inappropriate use of prior mathematical knowledge, limited ability to provide conceptual justifications, and a tendency toward procedural reasoning in contexts that require deeper conceptual analysis. These results suggest that students’ difficulties in recursive relations cannot be separated from the didactical situations framing the learning process. This preliminary study provides a foundation for the development of didactical designs in subsequent research, with the conceptual integration of the Case Method to reconstruct more meaningful learning situations in Discrete Mathematics.
