Abstract

This study aims to determine how the implementation of the Numbered Heads Together (NHT) learning model contributes to the improvement of students’ learning outcomes. The method used was a pre-experimental approach with a One-Group Pretest–Posttest design, involving only one class as the experimental group, without a control class. Data were collected through a pretest and a posttest, and then analyzed using the Normality test and the Hypothesis test (Paired Sample T-Test) with the SPSS Version 25 program. The research results showed that the average posttest score was 80.34, with the Paired Sample T-Test yielding a t-value of 9.396 and a significance level of 0.000 (p < 0.05), exceeding the established Minimum Mastery Criteria. These findings show that implementing the Numbered Heads Together learning model significantly improved students’ learning outcomes. Therefore, Numbered Heads Together can be used as an effective learning model to enhance the effectiveness of the learning process

Abstract

This study aims to examine the diversification of learning models that strengthen employability skills among students of Vocational High Schools (Sekolah Menengah Kejuruan; SMK) based on scientific publications published from 2015 to 2025. Vocational High School (SMK) graduates are expected to master technical competencies while also possessing 21st-century skills, such as communication, teamwork, problem-solving, creativity, digital literacy, and leadership, to adapt to the demands of the business and industrial sectors in the era of the Industrial Revolution 4.0. This study employed a Systematic Literature Review (SLR) approach, following the PRISMA Statement protocol, to select and analyze relevant articles published over the past decade. The results of the review indicate that six main learning models support the improvement of employability skills, namely Project-Based Learning (PBL), Problem-Based Learning (PBL), Work-Based Learning (WBL), Teaching Factory (TeFa), Blended Learning or Flipped Classroom, and Cooperative Learning. Each model provides a distinct contribution: PjBL and PBL strengthen critical thinking, problem solving, and collaboration skills; WBL and TeFa enhance adaptability, professional communication, and technological literacy; Blended Learning emphasizes digital literacy and learner autonomy; while Cooperative Learning reinforces interpersonal communication, teamwork, and leadership. This study concludes that no single learning model can comprehensively accommodate all aspects of employability skills. Therefore, the diversification and integration of various learning models during the 2015 to 2025 period becomes an essential strategy for building a vocational education ecosystem that is relevant and responsive to industry needs

Abstract

The accelerating environmental the accelerating environmental crisis including ecological degradation, climate change, and the depletion of natural resources poses serious challenges for educational institutions, particularly those carrying moral and spiritual responsibilities such as Islamic schools and madrasahs. This study explores how ecotheological leadership functions as an integrative ethical and managerial paradigm in responding to environmental challenges within Islamic educational institutions through leadership quality management practices. The primary issue addressed is the insufficient integration of ecological values into leadership management models that often emphasize administrative performance while neglecting environmental responsibility and spiritual ethics. Employing a qualitative descriptive approach supported by literature review, in-depth interviews, observations, and document analysis, this research investigates leadership practices grounded in Islamic ecotheological principles, including khalīfat al-arḍ (stewardship of the earth), amānah (trust), and maṣlaḥah (public good). The findings demonstrate that ecotheological leadership plays a crucial role in institutionalizing ecological ethics through participatory governance, curriculum integration, environmentally oriented policies, and accountability mechanisms within quality management systems. These approaches foster sustainability awareness among educators and students while strengthening institutional culture and responsibility. The study concludes that ecotheological leadership provides a transformative leadership model in which environmental stewardship becomes an essential component of educational governance rather than a peripheral initiative, aligning Islamic moral theology with sustainable development goals to ensure educational quality and ecological sustainability for present and future generations

Abstract

This research aims to develop a valid RADEC-based learning model for strengthening religious character values and improving critical thinking skills of elementary school students. The study employed a Research and Development (R&D) approach, limited to the stages of preliminary study, model design, expert validation, and revision. The RADEC learning model was developed by reconstructing its syntax Read, Answer, Discuss, Explain, and Create—through the explicit integration of religious character values and critical thinking indicators at each stage of the learning process. Data were collected using expert validation sheets completed by learning model experts and subject matter experts. The validation aspects included the suitability of learning objectives, clarity of RADEC syntax, integration of religious character values, integration of critical thinking skills, and overall feasibility of the model. Data were analyzed using descriptive quantitative techniques based on average scores. The results of expert validation showed average scores ranging from 4.4 to 4.6, which fall into the very valid category for all assessed aspects. These findings indicate that the developed RADEC-based learning model meets validity criteria and is conceptually feasible for use in elementary education. Therefore, the model can be used as a validated learning model prototype that may be further tested for practicality and effectiveness in future research to support character education and critical thinking development in line with the Pancasila Student Profile

Abstract

The The escalating global environmental crisis—reflected in climate change, ecological degradation, and declining environmental awareness—poses serious challenges for educational institutions, including Islamic Religious Education. This study examines the integration of eco-theology–based deep learning as a transformative pedagogical paradigm for cultivating environmental consciousness within Islamic Religious Education. The primary issue addressed is the limited integration of ecological values in prevailing instructional practices, which tend to prioritize cognitive achievement while insufficiently fostering ethical awareness and practical responsibility toward environmental stewardship. This research employs a qualitative descriptive approach through systematic literature review and conceptual analysis of educational theories, Islamic teachings, and eco-theological perspectives. The study formulates an integrative instructional framework that synthesizes deep learning principles such as critical inquiry, reflective engagement, collaborative learning, and experiential activities with Islamic environmental ethics grounded in the concepts of khilāfah, amānah, mīzān, avoidance of fasād, and wasatiyyah. The findings indicate that eco-theology–based deep learning promotes holistic student development encompassing cognitive understanding, affective awareness, and behavioral commitment to environmental care. Learners develop an enhanced perception of their role as khalīfah (stewards of the Earth), integrating spiritual consciousness, moral responsibility, and ecological literacy within real-life practices. The study concludes that eco-theology–based deep learning offers a viable and transformative model for reorienting Islamic Religious Education toward sustainability, character formation, and active engagement in addressing contemporary environmental challenges

Abstract

Engineering Design Thinking (EDT) has become a critical framework in contemporary engineering education by integrating creativity, human-centered perspectives, and systems thinking to address complex problems. This study aims to map the evolution of EDT research, identify dominant thematic structures, and indicate future research directions through a hybrid approach combining a Systematic Literature Review (SLR) and Bibliometric Analysis. Using the Scopus database, 893 publications published between 2020 and 2025 were analyzed following the PRISMA protocol and VOSviewer was used to visualize co-authorship, citation, and keyword networks. The results reveal a substantial increase in EDT-related publications after 2015, with the United States, China, and Indonesia emerging as leading contributors, indicating a growing global research landscape. Thematic analysis identifies five core and interrelated dimensions of EDT: technology integration, collaboration and communication, ideation and creativity, human-centered design, and systems and sustainability thinking. Despite this growth, empirical investigations and cross-regional collaborations remain limited. By integrating systematic and large-scale bibliometric perspectives and contextualizing recent studies within a broader historical trajectory (1957–2025), this research provides the first comprehensive mapping of EDT’s intellectual development and offers a unified conceptual model to guide future research and educational practice

Abstract

Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM)-based 3D printing technology is widely used in the manufacture of denture bases due to its precision and efficiency. However, the quality of the printed results is greatly influenced by printing parameters, especially the exposure time per layer that plays a role in the polymerization process of photopolymer resin. This study aims to analyze the effect of exposure time per layer on the dimensional accuracy and flexural strength of denture bases fabricated using Open System 3D Printing technology. This laboratory experimental study used a post-test only control group design. Denture bases were printed using an open system with exposure time variations of 4.5, 5, and 5.5 seconds, and compared with Close System 3D Printing and heat-polymerized acrylic resin (RAPP). Dimensional accuracy was measured in length, width, and height parameters, while flexural strength was tested using the three-point bending test method. Statistical analysis was performed using Welch's ANOVA test and Tukey's extended test (α = 0.05). The results showed that exposure time per layer had a significant effect on dimensional accuracy and flexural strength (p = 0.000). In the open system, the highest length accuracy value was obtained at an exposure time of 5.5 seconds (64.99 ± 0.07 mm), followed by 4.5 seconds (64.98 ± 0.09 mm) and 5 seconds (64.94 ± 0.05 mm). The highest flexural strength value in the open system was obtained at an exposure time of 4.5 seconds (68.90 ± 1.27 MPa), followed by 5.5 seconds (67.29 ± 1.49 MPa) and 5 seconds (66.08 ± 2.32 MPa). The closed system group showed the highest flexural strength value (90.61 ± 2.72 MPa), while RAPP was 73.76 ± 3.60 MPa. It was concluded that the exposure time setting per layer plays an important role in optimizing the dimensional accuracy and mechanical properties of 3D printed denture bases

Abstract

Advances in additive manufacturing have enabled the fabrication of denture bases using three-dimensional (3D) printing technology; however, the mechanical properties of the resulting materials, particularly impact strength, are highly influenced by post-processing parameters such as curing time. This experimental laboratory study aimed to evaluate the effect of different curing time variations on the impact strength of 3D-printed denture base resin and to compare its performance with that of heat-polymerized acrylic resin (HPAR). A post-test only control group design was employed, in which specimens were divided into four groups consisting of 3D-printed resin with curing times of 4.5, 5.0, and 5.5 seconds, and a control group fabricated from HPAR. The results demonstrated that the 3D-printed resin cured for 5.0 seconds exhibited the highest mean impact strength (1.56 ± 0.14 kJ/m²), followed by the 4.5-second group (1.47 ± 0.09 kJ/m²), while the lowest value was observed in the 5.5-second curing group (1.28 ± 0.23 kJ/m²). In contrast, the HPAR group showed substantially higher impact strength than all 3D-printed resin groups, with a mean value of 2.99 ± 0.97 kJ/m². These findings indicate that curing time optimization significantly affects the impact strength of 3D-printed denture base resin; nevertheless, heat-polymerized acrylic resin remains superior in terms of mechanical toughness for denture base applications
