Abstract

Purpose: This study aims to systematically review the mathematical concepts represented in Hill Cipher-based cryptography and examine their applications and implications for mathematics education across different educational levels. Methods: A systematic literature review was conducted following the PRISMA 2020 guidelines. Literature searches were performed across five academic databases, yielding 1,247 initial records. Following identification, screening, eligibility assessment, and quality appraisal, 14 primary studies published between 2020 and 2023 were included for qualitative thematic synthesis. Findings: The review identified modular arithmetic, matrix multiplication, and matrix inversion as the predominant mathematical concepts represented in the reviewed studies. Modular arithmetic appeared in all 14 studies and was primarily associated with secondary-level mathematics, whereas matrix operations were predominantly implemented in undergraduate contexts. The reviewed studies reported educational applications including mathematics learning media, simulation-based learning, and project-based learning. However, only a limited number of studies explicitly investigated classroom implementation, while most focused on algorithmic development and technical applications. In addition, the available evidence was dominated by studies conducted in Indonesia, limiting the broader generalizability of the findings. Research Implications: This review provides a conceptual synthesis that connects mathematical concepts, classical cryptographic algorithms, and their potential educational applications. The findings may inform mathematics educators, teacher educators, and curriculum developers in designing contextual mathematics learning activities while also highlighting the need for more classroom-based empirical studies across diverse educational settings. Originality: Unlike previous reviews emphasizing cryptographic performance and algorithm development, this study synthesizes the educational dimensions of Hill Cipher-based cryptography by mapping the relationships among mathematical concepts, instructional applications, and research gaps. The review contributes an evidence-based conceptual framework to support future research and curriculum development in mathematics education.

Abstract

Purpose: This study reports the classroom implementation and student-perceived usability of SIRKULASIKU, a visual novel game developed with the ADDIE model for fifth-grade IPAS (natural science) learning on the human circulatory system, and examines preliminary learning outcomes as indicative evidence of its instructional potential. Methods: A descriptive quantitative design with a one-group pretest–posttest component was used. Eighteen fifth-grade students (aged 10–11) from a private elementary school in Bekasi Regency participated in a single 70-minute session. Usability was measured with the Indonesian adaptation of the System Usability Scale (SUS); learning outcomes were measured with a 10-item multiple-choice test analysed using N-gain and the Wilcoxon signed-rank test. Findings: The mean SUS score was 73.75 (SD = 15.58), within the Good rating, with acceptable internal consistency (Cronbach’s α = 0.78), and learnability and ease of use as the strongest items. As preliminary single-group evidence, scores rose from 66.11 at pre-test to 90.56 at post-test, giving a mean N-gain of 0.725 (Wilcoxon W⁺ = 153.0, p < 0.001; effect size r = 0.85). An exploratory analysis found no significant link between usability and learning gain (Spearman’s ρ = 0.22, p = 0.37). Research Implications: The results offer preliminary, non-causal indications that a simple narrative-driven visual novel can support elementary science learning, and they suggest concrete design refinements, including an embedded tutorial and optional voice narration. Two measurement limitations should be acknowledged: the reliability and item characteristics of the knowledge test could not be assessed because item-level responses were not retained, and the SUS, which was developed for adult populations, may carry interpretive bias when used with children. Originality: This study advances the SIRKULASIKU project from expert-validated design to authentic classroom implementation, and provides a joint evaluations of usability and preliminary learning outcomes for a visual novel on the human circulatory system at the elementary level, an underexamined pairing in Indonesian IPAS research, where usability is rarely treated as a precondition for instructional value.

Abstract

Purpose: This study examines cultural hegemony in the Grade XII Islamic Religious Education (PAI) textbook under the Merdeka Curriculum from the perspectives of multicultural education and critical theory. It focuses on the role of textbooks in shaping religious knowledge and cultural representation in Indonesia’s multicultural context. Methods: A qualitative design using Norman Fairclough’s three-dimensional Critical Discourse Analysis was applied to one officially published Grade XII PAI textbook. The analysis covered textual narratives, visual representations, illustrations, and learning activities through the dimensions of text, discursive practice, and social practice. Findings: The textbook predominantly presents religious knowledge through centralized and normative narratives, while local Islamic traditions, interpretive plurality, and socio-cultural diversity receive limited representation. The discourse privileges standardized religious perspectives and reinforces dominant religious narratives. Conclusion: The textbook reflects cultural hegemony by privileging dominant religious interpretations and limiting multicultural perspectives. This indicates the need for more plural theological views, stronger representation of local Islamic traditions, and more inclusive textbook discourse. The findings are limited to the analyzed Grade XII textbook. Research Implications: Curriculum developers, textbook authors, educators, and policymakers should integrate multicultural education principles more fully into Islamic Religious Education materials to support inclusive and culturally responsive learning. Originality: This study integrates Fairclough’s Critical Discourse Analysis, Gramsci’s theory of cultural hegemony, and multicultural education to examine ideological representation in an official PAI textbook and propose a framework for more inclusive learning materials.

Abstract

Purpose: This study examines how fifth- and sixth-semester Japanese as a Foreign Language (JFL) students at Universitas Negeri Manado (UNIMA), an outer-island public university in North Sulawesi, Indonesia, use digital technologies to support self-regulated learning (SRL). It explores students' technology-use patterns, the SRL dimensions these tools support, and how local contextual factors shape technology-enhanced language learning. Methods: Using a qualitative case study design within an interpretive constructivist framework, data were collected over eight weeks from 30 participants through semi-structured interviews, an adapted Motivated Strategies for Learning Questionnaire (MSLQ, α = .87), classroom observation, and document analysis. Data were analyzed using thematic analysis alongside descriptive statistics. Findings: Participants showed a moderate overall SRL profile (M = 3.55), with goal-setting as the strongest dimension (M = 3.82) and self-evaluation as the weakest (M = 3.29). Four themes emerged: (1) tool selection driven by cost and peer recommendation, dominated by YouTube (93%), Duolingo (90%), and Anki (80%); (2) uneven digital support across SRL phases, with stronger support for practice than for self-reflection; (3) learning strategies adapted to limited local digital infrastructure; and (4) peer-based self-regulation supported through WhatsApp study groups. Research Implications: These findings suggest a need for explicit teaching strategies that build students' self-reflection skills, greater investment in campus digital infrastructure, and formal recognition of peer study groups as part of language learning support. Originality: This study introduces the concept of phase-differential digital scaffolding uneven technological support across different stages of self-regulated learning and shows how students adapt their strategies within an under-resourced, outer-island setting, extending existing research that has mainly focused on urban, well-resourced contexts. Limitations: As a single-site case study with 30 participants, findings may not generalize to other institutions or regions; self-reported data may also be subject to social desirability bias.

Abstract

Purpose: This study aims to examine the role of boarding school culture in shaping the professional character of vocational students. Specifically, it explores how values, routines, and social interactions within boarding school environments contribute to the development of discipline, responsibility, work ethics, independence, and interpersonal skills essential for students’ readiness to enter the workforce. Methods: This research employs a qualitative case study approach conducted at a vocational boarding school. Data were collected through in-depth interviews with students, teachers, dormitory supervisors, and school administrators, complemented by participant observation and document analysis. The data were analyzed using thematic analysis to identify patterns and meanings related to character formation processes influenced by boarding school culture. Findings: The findings reveal that boarding school culture plays a significant role in shaping students’ professional character through structured daily routines, value internalization, role modeling by educators, and consistent social control within the dormitory setting. Practices such as collective worship, time management, shared responsibilities, and experiential learning foster students’ self-discipline, accountability, teamwork, independence, and ethical behavior. These character traits are consistently reflected in students’ attitudes toward learning and work-related activities, demonstrating alignment with vocational education objectives. Research Implications: The study provides empirical evidence that boarding school environments can serve as a strategic model for strengthening character-based vocational education by bridging the gap between technical skill development and professional character formation. Originality: This study offers a novel contribution by integrating boarding school culture with professional character development in vocational education, an area that remains underexplored in existing literature.

Abstract

Purpose: This study aimed to construct a diagnostic profile of inferential reading ability across four indicators anaphoric resolution, background knowledge activation, predictive reasoning, and retrospective synthesis among fifth-grade students in Bandung elementary schools, addressing the limited availability of dimension-specific empirical data on inferential reading performance at the primary level. Methods: A descriptive survey was conducted with 84 fifth-grade students from three public elementary schools in Bandung, who completed an inferential reading test structured around the four indicators. A broader cohort of 185 students from the same schools responded to a perception questionnaire, while 35 teachers completed a questionnaire on instructional practices. Semi-structured interviews were also conducted with three classroom teachers and three students. Descriptive statistics, frequency distributions, cross-school comparisons, and thematic analysis were employed. Findings: The overall mean score was 45.83 (SD = 15.94), with the majority of students performing below expected levels. Retrospective synthesis recorded the lowest mean (M = 39.06, 84.5% in the lowest category), followed by predictive reasoning and background knowledge activation (78.6% each). Anaphoric resolution, although the highest (M = 54.69), still left more than half of the students below the expected threshold. Comparable patterns were observed across the three schools. Research Implications: The findings indicate that inferential reading competence requires more systematic instructional attention, particularly in retrospective synthesis and predictive reasoning. The four-indicator diagnostic framework offers educators a tool for pinpointing dimension-specific weaknesses and provides researchers a baseline for future intervention studies. Originality: This study contributes an empirically grounded diagnostic profile of inferential reading ability across four discrete indicators at the elementary level, integrating objective test data with teacher and student perceptual evidence within a single analytical framework.

Abstract

This study examines the effect of a play-based learning approach on beginning reading and simple sentence writing skills among first-grade elementary school students. A pre-experimental study employing a one-group pretest–posttest design was conducted with 25 first-grade students selected through total sampling. Data were collected through beginning reading and simple sentence writing tests administered before and after the implementation of the play-based learning approach and analyzed using descriptive statistics and a paired-samples t-test at a significance level of 0.05. The results showed that students’ literacy performance improved significantly after the intervention. The mean score increased from 65.00 in the pretest to 82.00 in the posttest, while the percentage of students achieving mastery learning rose from 32% to 84%. The paired-samples t-test confirmed a statistically significant difference between pretest and posttest scores (t = [insert t-value], p < 0.001), indicating that the play-based learning approach effectively enhanced students’ beginning reading and simple sentence writing skills. These findings suggest that integrating play-based learning into early-grade literacy instruction can create more active, meaningful, and developmentally appropriate learning experiences. This study contributes to the literature by providing empirical evidence on the simultaneous improvement of beginning reading and simple sentence writing skills through a play-based learning approach, offering a more comprehensive perspective on early literacy development in elementary education.

Abstract

This research is crucial to determine the extent to which educators' adaptation of technology and digital literacy in cyberspace has transformed into effective role models and tools for improving the quality of education. The purpose of this study is to analyze the relationship between creativity in developing learning content and learning professionalism, and the relationship between social media behavior and learning professionalism. This study employed quantitative research with a correlational survey approach. Through this approach, researchers can objectively describe, measure, and analyze the relationships between variables based on empirical data from elementary school teachers in the Gunungwungkal area of Pati. The population in this study was all elementary school teachers in the Gunungwungkal area. The sample of 31 teachers was selected using simple random sampling. The study involved three main variables: creativity in developing learning content and social media behavior as independent variables, and teacher learning professionalism as dependent variable. Each variable was measured through indicators compiled into a questionnaire instrument using a Likert scale of 1–5. The analysis used SmartPLS to evaluate the structural equation model (SEM-PLS) through two stages: the Outer Model (testing the validity and reliability of the instrument) and the Inner Model (testing the influence between variables). The research results show that creative content development has a positive relationship with learning professionalism, and social media behavior is also related to learning professionalism. Teacher creativity and social media behavior have been empirically proven to have a very strong correlation with improving teacher professional competence.

Abstract

Purpose: This research aims to develop an environmentally based practicum E-LKPD (electronic student worksheet) on Chemical Equilibrium material to address laboratory facility limitations and produce a valid, practical product with potential to improve students' conceptual understanding. Methods: This study used the Research and Development (R&D) method with a 3D model (Define, Design, Develop) modified from the 4D model. Subjects were 11th-grade high school students, involving a small-scale trial (9 students) and a large-scale trial (27 students) selected via purposive sampling. Data were collected through expert validation sheets, student response questionnaires, and pretest-posttest questions, then analyzed using validity and practicality percentages and Normalized Gain (N-gain). Findings: The E-LKPD was rated very valid by media experts (95.83%) and material experts (94.44%), and very practical based on student responses (86.36% small-scale; 87.04% large-scale). Average N-gain of 0.90 (small-scale) and 0.92 (large-scale), both in the high category, indicated the E-LKPD's potential to improve conceptual understanding. Research Limitations: This research was conducted in only one class at one school without a comparison group, so generalizability remains limited and further research in a broader context is needed. Research Implications: This E-LKPD can serve as an economical, applicable, and environmentally friendly alternative teaching material for chemistry teachers, particularly in schools with limited laboratory facilities, enabling more contextual and interactive chemical equilibrium learning. Originality: This research develops an environment-based practicum E-LKPD integrating local environmental potential with interactive digital features for chemical equilibrium learning, an approach still relatively rare in previous studies.
