Abstract

This study aims to develop and evaluate a Project-Based Learning integrated with STEM (PjBL-STEM) learning program oriented toward deep learning principles—encompassing mindful, meaningful, and joyful learning—within the IPAS (Natural and Social Sciences) subject for tenth-grade vocational high school students. Motivated by the persistent gap between conventional instructional practice and the competency demands of Industry 4.0, the study developed a structured instructional package consisting of a Deep Learning Lesson Plan (Perencanaan Pembelajaran Mendalam/PPM), student worksheets (LKPD), and supporting handouts, all anchored in the PjBL-STEM framework applied to electromagnetic induction as a sustainable energy technology context. The research employed a mixed-method approach guided by the four-stage 4D instructional development model (Define, Design, Develop, Disseminate). The study involved two classes of tenth-grade students enrolled in the Electrical Power Installation Engineering program (X TITL-1 as experimental group; X TITL-2 as control group) at a public vocational high school in Bandar Lampung during the 2025/2026 academic year. Expert validation by three specialists yielded an overall validity score of 91.9% for the lesson plan and 91.5% for the student worksheets and handouts, both classified as highly valid. Teacher practicality evaluation indicated an overall score of 90.7%, categorized as excellent. Effectiveness analysis using the normalized gain (N-Gain) index revealed that the experimental group achieved a mean N-Gain of 0.90 (high category) for performance skills and 1.00 (high category) for creativity, compared with 0.30 and 0.45, respectively, for the control group receiving conventional instruction. These findings establish that integrating PjBL-STEM with deep learning principles produces a valid, practical, and effective instructional framework capable of significantly enhancing vocational students' creativity and practical performance competencies relevant to contemporary technological challenges.

Abstract

Research on English as a Foreign Language (EFL) writing instruction has expanded substantially over the last decade, reflecting growing interest in pedagogical innovation, learner-centered instruction, feedback practices, and technology-mediated writing. However, the field remains fragmented, as existing studies often examine isolated instructional strategies, learner populations, or digital interventions without offering an integrated view of its intellectual structure and pedagogical development. This study maps and synthesizes Scopus-indexed research on EFL writing instruction published between 2015 and 2024 through an integrated bibliometric analysis and systematic literature review. A total of 1,030 journal articles were analyzed bibliometrically using Biblioshiny and VOSviewer to examine publication trends, influential authors, source journals, contributing countries, citation patterns, and keyword co-occurrence networks. Following PRISMA 2020 guidelines, 82 empirical studies were further selected for qualitative synthesis. The findings reveal a steady increase in EFL writing instruction research, with accelerated growth between 2021 and 2024. Genre-based, process-oriented, and strategy-based instruction emerged as dominant pedagogical approaches, while sociocultural, cognitive, sociocognitive, and self-regulated learning frameworks commonly informed the field. Persistent challenges include learners’ limited linguistic and rhetorical resources, writing anxiety, low confidence, instructional constraints, and feedback-related difficulties. At the same time, technology-enhanced and AI-assisted writing tools offer opportunities for feedback, collaboration, learner autonomy, and instructional innovation. This review contributes an integrated understanding of EFL writing instruction research by connecting bibliometric patterns with pedagogical and theoretical insights, while highlighting future directions for longitudinal, teacher-focused, contextually diverse, and ethically informed studies on digital and AI-supported writing pedagogy.

Abstract

Preparing future physics teachers requires instructional models that intentionally integrate critical pedagogy, collaborative learning, and socioscientific inquiry to cultivate essential twenty-first-century competencies. However, existing approaches rarely connect these dimensions within a coherent instructional framework. This study developed and evaluated the Critical–Collaborative Learning Model (CCLM) to foster creative thinking and collaboration among prospective physics teachers. A research and development approach adapted from the Borg and Gall model was implemented through needs analysis, model design, expert validation, formative evaluation, and field testing. Data were collected using validation sheets, practicality questionnaires, creative-thinking assessments, and collaboration-skill questionnaires. The findings indicate that CCLM demonstrated high validity and practicality and produced stronger creative thinking and collaboration outcomes than conventional instruction. The model encouraged critical literacy, collaborative dialogue, creative production, and action-oriented learning through engagement with socioscientific issues, enabling students to generate more original ideas while strengthening collaborative problem-solving and shared responsibility. This study contributes a validated instructional framework that systematically integrates critical pedagogy and collaborative inquiry to support the development of higher-order competencies in physics teacher education.

Abstract

Learning about global warming in schools is often theoretical and lacks meaningful, real-world problem-solving activities that engage students. As a result, students’ 21st-century skills, such as critical thinking, collaboration, and digital literacy, are not optimally developed due to the lack of innovative, differentiated learning media, including project-based e-worksheets that utilize the STEM approach. This study aims to develop a differentiated, project-based student worksheet utilizing a STEM approach that is valid, practical, and effective in training students' 21st-century skills, particularly in the context of global warming and the greenhouse effect. The research method used is development research, with the ADDIE design, consisting of the stages Analyze, Design, Development, Implementation, and Evaluation. This research was conducted in three meetings at SMAN 1 Katibung. Data analysis techniques include percentage analysis for validity and practicality scores, as well as statistical analysis to determine effectiveness. The results show that the differentiated worksheet developed has high validity in terms of content, construct, language, and design, with a score of 87.08%. In terms of practicality, it demonstrates high levels of readability, attractiveness, and feasibility, scoring 88.3%, categorized as very practical. Furthermore, the e-Worksheet has been proven effective in fostering students’ 21st-century skills, as evidenced by N-Gain scores of 0.61 (moderate improvement) for critical thinking and 0.56 (moderate) for creative thinking. The application of differentiated learning in the experimental class showed a moderate effect size of 0.469 for critical thinking skills and 0.294 for creative thinking skills. These findings indicate that the differentiated project-based e-worksheet can accommodate students’ varying needs, including their initial abilities and learning styles, and is necessary to support the development of 21st-century skills.

Abstract

Problem-solving skills are a crucial competency in physics learning, but assessments of optical instrument materials often focus solely on routine tasks and final project results, without incorporating integrated project-based assessment tools. This study aims to analyze students' problem-solving skills using a project-based assessment on optical instrument materials, following the steps outlined by Heller and Heller. This study employed descriptive research with 64 eleventh-grade students as subjects. The assessment instruments were developed based on problem-solving indicators, as outlined by Heller and Heller, including problem focus, problem description, solution planning, plan implementation, and solution evaluation. Data were collected through observation of students' learning activities and analyzed using descriptive statistics in the form of achievement percentages. The study's results demonstrated a high level of validity, as verified by experts, and a high level of practicality, supported by positive responses from students. Problem-solving indicators, including focus on the problem, solution planning, plan implementation, and solution evaluation, achieved an average of 82% (very good category), while the problem description indicator achieved 77% (good category). These findings suggest that project-based assessment tools have potential in supporting the development of students' problem-solving skills, although they need to be strengthened in terms of physically describing problems. This study contributes to the alignment of project-based problem-solving indicators, offering a process-oriented and contextual approach to assessing cognitive skills. Further research is recommended to test the effectiveness of PjBL directly on improving students' problem-solving skills through experimental designs with control groups, as well as the development of more adaptive digital instruments for application in 21st-century physics education.

Abstract

Learning in Vocational High Schools (VHS) requires instructional strategies that can accommodate the diversity of students’ needs, characteristics, and learning readiness. However, predominantly uniform instructional practices are often not optimal for comprehensively improving students’ learning outcomes. This study aims to develop a differentiated learning strategy model based on students’ needs to enhance the learning outcomes of vocational high school students. The study employed a quantitative approach using an explanatory survey design. The research participants consisted of vocational high school students, and data were collected through instruments designed to identify students’ needs, assess the implementation of differentiated learning strategies, and measure learning outcomes. The data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) to examine the relationships among the constructs in the proposed model. The findings indicate that differentiated learning strategies positively affect students’ learning outcomes, while identifying students’ needs also significantly influences both the implementation of learning strategies and learning achievement. These findings confirm that adaptive, personalized, and student-centered learning is more effective than uniform instructional approaches. This study's novelty lies in developing a differentiated learning model for the vocational education context, based on students’ needs and validated using the SEM-PLS approach. This research strengthens the conceptual and practical foundations for developing adaptive learning in vocational education to improve both the quality of the learning process and learning outcomes.
