Abstract

This study aimed to develop an ethnomathematics-based digital comic on Systems of Linear Equations in Two Variables (SLETV) and to examine its validity, practicality, and potential effectiveness in supporting students’ mathematical literacy. The study employed a Research and Development (R&D) approach using the 4D model, consisting of define, design, develop, and disseminate stages, although the development process was limited to the develop stage. A one-group pretest–posttest design was applied during the field-testing phase without a comparison group. The participants included 10 eighth-grade students and one mathematics teacher in the limited trial, followed by 30 eighth-grade students and one mathematics teacher in the field trial at Mangunan Eksperimental Junior High School. Data were collected through observations, interviews, questionnaires, and mathematical literacy tests. The literacy assessment was designed based on the OECD mathematical literacy processes of formulating, employing, and interpreting mathematics in contextual situations. The developed digital comic integrates Yogyakarta cultural contexts, including batik and local culinary products, into literacy-oriented SLETV learning activities. The validation results indicated a very high level of validity, with scores of 94% from content experts and 86% from media experts. Practicality was supported by positive responses from students (87.86%) and teachers (86%). The field trial results showed an improvement in students’ mathematical literacy, as reflected in an average N-Gain score of 0.58, categorized as moderate, and a statistically significant difference between pretest and posttest scores. These findings suggest that the developed digital comic has the potential to support mathematical literacy development in the tested context and may serve as a valid and practical learning medium for junior high school mathematics learning. This study contributes to mathematics education by demonstrating how local ethnomathematical contexts can be systematically integrated into digital comic media to promote OECD-oriented mathematical literacy in SLETV learning.

Abstract

The objective is to provide knowledge for pure mathematics and mathematics education students to understand quantified statements so that they can easily comprehend the meaning of mathematical propositions and facilitate their proof. The method used in this research is a literature review by collecting various sources such as books or scientific writings related to the logic used to understand mathematics, specifically related to quantifiers, both universal and existential quantifiers. When mathematics and mathematics education students understand the quantified statement ∀x[Px], what they do is take any (cannot choose specific) x, and it must be proven that x satisfies property P. Then, to understand the quantified statement ∃x[Px], what is done is to choose (at least one) x, and it must be proven that x satisfies property P. When mathematics and mathematics education students understand the multi-quantifier statement ∀x∃y[P(x,y)], what is done is to take any (cannot choose specific) x, then find (at least one) y (depending on x), and x, y must satisfy property P. Then, to understand the multi-quantifier statement ∃y ∀x[P(x,y)] or ∃y [P(x,y)∀x], what is done is to choose y (independent of x) and it must be proven that y satisfies property P along with all x.

Abstract

The integration of machine learning (ML) with immersive technologies—Virtual Reality (VR), Augmented Reality (AR), Mixed Reality (MR), and Extended Reality (XR)—has generated significant momentum in educational innovation over the past decade. ML-enhanced immersive environments now support adaptive feedback, multimodal sensing, pose estimation, automated performance evaluation, and real-time learning analytics, offering new pathways for personalized and experiential learning. Despite rapid growth, existing research remains fragmented across domains such as engineering, health, arts, and language education, with limited synthesis explaining how these studies connect, evolve, and shape the knowledge structure of ML–VR/AR research. To address this gap, this study conducted a combined Systematic Literature Review (SLR) and bibliometric analysis of Scopus-indexed publications from 2015 to 2025. Eligibility assessment resulted in 58 studies included in the final analysis. Bibliometric findings show consistent growth in ML–VR/AR educational research, with publications spread across diverse journals and domains. This review offers a comprehensive mapping of scientific influence, thematic structure, and developmental trajectories in ML–VR/AR educational research. Findings provide a foundation for advancing adaptive immersive learning models, strengthening theoretical integration, and guiding future ML-driven XR innovations across educational contexts.

Abstract

This study aims to describe the perceptions of class X students of Light Vehicle Engineering (TKR) towards mathematics learning and its impact on students' learning interests and attitudes. The study was conducted at one of the vocational schools in Yogyakarta with a qualitative approach and descriptive method. Data were collected using triangulation techniques through observation, open questionnaires, and in-depth interviews. The results showed that most students had negative perceptions of mathematics, which were considered difficult, confusing, and irrelevant to life or work in the automotive field. This perception resulted in low interest and negative attitudes such as indifference, passivity, and lack of enthusiasm. However, there were students who showed positive attitudes when the material presented was considered relevant and easy to understand. These findings indicate a close relationship between students' perceptions, interests, and attitudes towards mathematics learning. Therefore, it is important for educators to design learning strategies that are more contextual, applicable, and in accordance with the world of work in order to form positive perceptions of mathematics.

Abstract

Students' errors in solving mathematical problems reflect their level of understanding and systematic thinking skills. This qualitative study aims to identify the types of errors and factors causing students' difficulties in solving the System of Linear Equations in Two Variables (SPLDV). The subjects were three eighth-grade junior high school students in Banjarnegara who were selected purposively. Data were obtained through written tests, in-depth interviews, and documentation. The results showed three main error categories: errors in modeling problems, calculations, and incomplete answer structures. The contributing factors include weak conceptual understanding, minimal contextual practice, the habit of solving problems instantly, and a lack of thorough problem interpretation. These findings are expected to provide an empirical basis for teachers and curriculum developers in designing effective learning and emphasizing conceptual understanding, contextual practice, reasoning, and systematic communication in SPLDV material

Abstract

Background: Google Sites is commonly used as a static repository for learning materials, limiting its potential to foster meaningful cognitive engagement in mathematics education. Moreover, few studies have integrated Ki Hadjar Dewantara's Tri-N philosophy (Niteni, Nirokke, Nambahi) with Cognitive Load Theory (CLT) to design culturally responsive and cognitively structured e-learning, particularly for junior high school statistics. Purpose: This study aimed to develop and validate a Google Sites-based e-learning platform grounded in Tri-N philosophy and CLT for Grade VIII statistics learning. Method: This Research and Development (R&D) study employed a modified 3D development model adapted from Thiagarajan's 4D model, consisting of the Define, Design, and Develop stages. Participants included 32 Grade VIII students and one mathematics teacher. Data were gathered through observations, interviews, expert validation questionnaires, and student response questionnaires. Specific instruments were used to measure CLT aspects (e.g., intrinsic, extraneous, and germane cognitive load items) and Tri-N integration (e.g., items assessing niteni–observation, nirokke–imitation, and nambahi–creation activities). Data were analyzed using descriptive qualitative and quantitative techniques. Findings: The developed e-learning product showed high validity and practicality. Content expert validation yielded a mean score of 4.05 (Valid), and media expert validation reached 4.44 (Highly Valid). Student practicality assessments indicated Practical levels, with overall means of 3.61 (limited trial) and 3.93 (large-scale trial). These findings suggest that integrating Tri-N with CLT provides a culturally responsive and cognitively optimized framework that enhances meaningful digital learning. This approach offers practical implications for designing local wisdom-based e-learning and warrants further research on its effectiveness in broader educational contexts and longer implementation periods
