Abstract

Mathematics is often seen as a challenging subject that demands not only cognitive ability but also sustained motivation. This study investigates how peer interaction can act as a catalyst for enhancing students’ motivation to learn mathematics. Adopting a qualitative approach with a survey design, data were collected from 40 high school and vocational students in Gunungkidul, Indonesia. Thematic analysis of open-ended questionnaire responses revealed that 72% of students reported higher motivation when learning alongside peers. Key motivational drivers included emotional support, collaborative problem-solving, and peer-driven encouragement. Interestingly, the study also highlighted potential setbacks such as interpersonal conflicts, which may reduce motivation. These findings affirm the transformative role of peer relationships in academic contexts and suggest that fostering supportive peer networks can be a strategic tool in improving students’ engagement with mathematics. This study contributes to educational psychology and mathematics education by demonstrating that peer interaction not only fosters emotional well-being but also improves students’ cognitive engagement with complex mathematical concepts. The findings offer practical insights into how structured peer collaboration can be integrated into instructional design to support diverse learner needs. By highlighting the dual role of peer interaction, as both an academic and affective resource, the study provides a foundation for developing socially responsive and student-centered learning environments aimed at improving mathematical achievement.

Abstract

Mathematics is often perceived as a difficult subject that triggers anxiety, especially among students facing academic pressure. This study aims to analyze and describe the level of mathematics anxiety experienced by final-year vocational high school students. Employing a descriptive qualitative approach, data were collected through a questionnaire distributed to six randomly selected Grade XII students from a vocational school in Gedangsari. The instrument consisted of 23 statements: 6 positive and 17 negative using a Likert scale to assess students’ anxiety. Data analysis followed the Miles & Huberman model, which includes data reduction, display, and verification. The results showed varying levels of mathematics anxiety: 2 students were categorized as having very high anxiety, 3 were in the moderate category, and 1 student experienced very low anxiety. Students with high anxiety reported symptoms such as trembling hands, increased heart rate, mental blocks, and a lack of confidence during mathematics tasks. Meanwhile, students with lower anxiety demonstrated greater emotional control, focus, and proactive engagement in learning activities. The findings indicate that mathematics anxiety can significantly hinder students’ cognitive and emotional capacity to learn effectively. This study contributes to educational psychology by providing insight into how mathematics anxiety manifests among vocational high school students. It highlights the importance of recognizing emotional factors in learning, particularly in high-pressure academic contexts. The results can inform teachers, counselors, and curriculum designers in developing supportive strategies to reduce anxiety and enhance mathematical engagement in vocational education. In conclusion, addressing mathematics anxiety is crucial for fostering a positive and supportive learning environment that empowers students to perform better academically. This research contributes to the understanding of mathematics anxiety in vocational education and emphasizes the need for empathetic, emotion-sensitive teaching approaches that support both cognitive and emotional student development.

Abstract

This bibliometric study analyzed 309 Scopus-indexed documents (2007–2026) to examine research trends integrating Virtual Reality (VR), electric bicycle conversion, and vocational education. The study used a bibliometric approach to map scientific developments at the intersection of VR, e-mobility, and vocational education. Findings indicate that this field is rapidly developing, with an annual growth rate of 3.72% and a very young average document age (2.08 years). China, India, and the United States dominate publications, while Europe leads in international collaboration. Through thematic mapping, VR was identified as a key link bridging sustainability, transportation safety, and smart city technology. VR and electric vehicle development were among the Basic Themes, while transportation safety emerged as a Motor Theme with strong momentum. However, the analysis revealed a critical gap: the lack of engagement with vocational education and e-learning topics. The lack of exploration of VR as a training tool for electric bicycle conversion in vocational high schools suggests a broad research opportunity. This study emphasizes the importance of integrating immersive simulation and competency-based learning to prepare a skilled workforce in the future sustainable transportation sector.

Abstract

This study investigates the relationship between mathematical anxiety, learning motivation, and mathematics learning outcomes among seventh-grade students in the Tamansiswa environment. Employing a quantitative ex-post facto method, data were collected from 56 students across two schools using questionnaires and academic performance records. The results revealed a significant and negative correlation between mathematical anxiety and learning outcomes, highlighting the detrimental effects of heightened anxiety on students' academic performance. Conversely, learning motivation demonstrated a significant positive influence, emphasizing its crucial role in fostering engagement and persistence in mathematics learning. The combined analysis of these variables showed that 52.2% of the variance in mathematics learning outcomes could be explained by the interaction between anxiety and motivation. Interestingly, despite high levels of anxiety, some students achieved strong learning outcomes, suggesting the presence of mitigating factors such as resilience or effective coping strategies. These findings underscore the importance of reducing anxiety and enhancing motivation through targeted educational interventions, such as supportive teaching practices and motivational strategies, to optimize mathematics learning outcomes. In conclusion, mathematics learning outcomes are shaped by a complex interaction between emotional and motivational factors. Reducing mathematical anxiety while simultaneously strengthening learning motivation is crucial for optimizing students’ achievement in mathematics. The study contributes empirically by providing evidence of the combined influence of anxiety and motivation within the Tamansiswa context, and practically by offering insights for educators to design instructional strategies that are both emotionally supportive and motivationally engaging. These findings reinforce the importance of integrating psychological considerations into mathematics instruction to promote more effective and inclusive learning environments.

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

Roblox has emerged as a prominent platform-based learning environment that bridges gamification, immersive virtual worlds, and interactive pedagogies. Despite its growing adoption in educational contexts, the global research landscape on Roblox Education has not yet been systematically mapped. This study aims to analyze the structure, dynamics, and thematic evolution of scholarly publications related to Roblox-based learning within the Scopus database from 2020 to 2025. Using a bibliometric approach supported by performance analysis and science mapping techniques in Biblioshiny, this study examines 37 documents indexed in 26 sources, involving 214 authors and an annual growth rate of 58.49%. The findings reveal high collaboration intensity (8.78 co-authors per document) and considerable academic influence, with an average of 69.97 citations per publication. Korea, the United States, Indonesia, India, Spain, and China emerged as leading contributors to the field. Science mapping shows four dominant thematic structures: (i) metaverse and virtual reality as motor themes; (ii) Roblox, education, artificial intelligence, and e-learning as basic themes; (iii) educational alternatives and niche digital environments as highly developed but isolated themes; and (iv) emerging or declining themes, including avatars, computational theory, and video games. Trend analysis indicates a strong shift from conventional e-learning toward immersive, metaverse-driven, and game-based pedagogies between 2022 and 2024. Reference spectroscopy highlights 2020–2023 as a pivotal period marked by rapid theoretical expansion following global pandemic-related digitization. Overall, the findings demonstrate that Roblox Education represents a rapidly maturing and multidisciplinary research domain, with substantial potential to support experiential learning, digital creativity, and the remediation of learning loss. Implications for future research include the integration of adaptive AI, immersive assessment frameworks, and curriculum-level adoption of platform-based learning.

Abstract

Many students face challenges in reasoning through statistical data problems; however, little is known about how their thinking processes develop through different cognitive stages. A qualitative descriptive design was employed to explore students’ reasoning patterns in solving statistical data problems through the lens of Action, Process, Object, and Schema (APOS) theory. This study was conducted with seventh-grade students at a public junior high school in Kulon Progo, Indonesia. Data were collected through written tests and semi-structured interviews and were analyzed using coding techniques aligned with the APOS indicators. The results show that students with correct answers demonstrated conceptual reasoning and progressed through all APOS stages, whereas those with incorrect answers showed fragmented understanding and failed to complete the cognitive sequence. This study contributes to mathematics education by extending the APOS theory to statistical data representation at the secondary level.

Abstract

Learning outcomes are one of the important aspects in the learning process because it is used as a determining factor for the success of a learning process. The factors that influence student learning outcomes are divided into two, namely internal factors (learning interests, talents, motivation, self-regulation, etc.) and external factors (school environment, family environment, etc.). Self-regulation and learning interest were the focus of discussion in this research. This study aims to determine the positive and significant influence between independence and interest in learning on mathematics learning outcomes for class VIII students of SMP Negeri 24 Muaro Jambi. This type of research is associative quantitative research. The results showed that partially independence had a positive but not significant effect on mathematics learning outcomes with tcount = 1,323 and correlation coefficient 0,202, while interest in learning had a positive and significant effect mathematics learning outcomes with tcount = 4,193 and correlation coefficient 0,548. Simultaneously, independence and interest in learning have a positive and significant effect on mathematics learning outcomes for class VIII students of SMP Negeri 24 Muaro Jambi as shown by the Fcount = 41,196, with an effect of 66,8% and 33,2% influenced by other variables.
