Abstract

This study investigates the role of game-based educational tools within a Project-Based Learning (PBL) framework in enhancing students' problem-solving skills. Faced with the demands of Industry 4.0 and the Sustainable Development Goals (SDGs), there is a critical need for innovative learning approaches that foster problem-solving and creativity among prospective teachers. This research adopted a 4D model (Define, Design, Develop, Disseminate) to develop a game-based PBL learning device, tested over six months with 27 university students across different semesters. The findings indicate that the integration of educational games significantly contributes to the development of problem-solving abilities. Students actively engaged in real-world project challenges through games, which facilitated the identification, formulation, strategy implementation, and solution verification stages of problem-solving. While the 'identifying problems' and 'verifying solutions' aspects showed areas for further improvement, the overall process demonstrated a positive impact on students' capacity to tackle complex issues effectively. This highlights the potential of game-based PBL as an engaging and effective pedagogical tool for cultivating essential problem-solving competencies in higher education.

Abstract

The low level of students' physics concept understanding is often caused by conventional learning processes and the lack of varied representational media. This study aims to investigate the effect of the Jigsaw-type cooperative learning model with a multimodal approach on students' physics concept understanding. This research employed a quasi-experimental method with a non-equivalent control group design. The population comprised all Grade 11 students at MA Nurul Iman, with samples selected via purposive sampling. Data were collected using a physics concept understanding test instrument consisting of multiple-choice items. Data analysis was performed using IBM SPSS Statistics 25, involving prerequisite tests followed by an Independent Sample T-test. The results indicated that the mean posttest score of the experimental class (84.29) was significantly higher than that of the control class (75.75). Hypothesis testing revealed a significance value (Sig. 2-tailed) of 0.018 < 0.05, leading to the rejection of H0 and the acceptance of Ha. Consequently, it can be concluded that the Jigsaw-type cooperative learning model with a multimodal approach has a significant effect on improving students' physics concept understanding. The integration of various representational modes effectively helps students visualize abstract concepts and strengthens cognitive construction through peer tutoring interactions.

Abstract

Creativity is a crucial aspect of physics learning that is often overlooked due to the dominance of conventional learning methods. This study aims to analyze the influence of the Jigsaw cooperative learning model with a multimodal approach on the creativity of grade XI students at MA Nurul Iman. This research is a quasi-experiment using a non-equivalent control group design. The research instrument consisted of a creativity test in the form of four complex essay items that were declared valid (rxy>0,443) and reliable (r11>0.443). The results showed that the average posttest score of the experimental class (78) was higher than the control class (65.05). The Independent Sample T-test results obtained a significance value (2-tailed) of 0.002 < 0.05, so Ha was accepted. It can be concluded that the implementation of the Jigsaw model with a multimodal approach has a significant effect on students' creativity. The synergy between individual responsibility in groups and the diversity of representation modes effectively stimulates indicators of fluency, flexibility, originality, and elaboration.

Abstract

This study aims to elucidate the development process and validate the research instruments and learning materials employed in a study investigating the enhancement of creative thinking skills in pre-service physics teachers through a Project-Based Learning (PjBL) model integrated with e-modules. The validated components include a creative thinking test instrument (measuring fluency, flexibility, elaboration, and originality), a PjBL creative process assessment instrument, a creative product assessment rubric (for videos, websites, games, and posters), and the design of the e-module and its supporting media. The validation process was conducted by three expert validators who evaluated aspects of content, construct, language, and technicality. Validation results revealed overwhelmingly positive assessments, with average scores for all instruments and materials falling into the 'very good' category (ranging from 4.33 to 5.00 on a 5-point scale). Specifically, the creative thinking test instrument was highly rated for its alignment with creativity indicators; the creative process assessment sheet was deemed detailed and systematic; the creative product rubric achieved perfect scores for objective evaluation; and the e-module was judged highly engaging and effective in facilitating self-regulated learning integrated with PjBL syntax. These findings affirm that the developed instruments and learning materials possess high validity and are ready for accurate and comprehensive measurement and facilitation of creative thinking skills in pre-service physics teachers.

Abstract

The aircraft used in this study is the upper wing type which has the advantage of flight stability. This upper wing aircraft was designed by the researchers themselves with three different types of wings with a wing span of 1.35m and a fuse lag of 0.925 meters. There are four main forces that work when the plane is in the air, namely lift, thrust, air resistance and gravity. From the results of this study, it can be concluded that the heavier the aircraft unit being flown, the greater the minimum thrust required to fly the aircraft. The measurement results of the 3 aircraft weights, namely 917 grams, require a thrust of 2030 grams of force, whereas for a total aircraft weight of 1,230 grams a thrust of 2510 grams is required, and at an aircraft weight of 1495 grams a minimum thrust of 3040 grams is required. The results also show that the thrust generated is not linear with the throttle position

Abstract

Refraction of light occurs due to the difference in the speed of light in the two mediums where the speed of light in a dense medium is smaller than the speed of light in a less dense medium. One of the refraction phenomena also occurs in prism glass. Prisms help scatter incoming light from monochromatic light sources. To prove this, refraction experiments can be carried out using a prism. Where the prism used is made manually using used glass made of acrylic. The prism that is made is then filled with water on the inside and a test is carried out to determine the refraction and the value of the angle of deviation. Based on the results obtained, the refraction of the prism glass made in where a beam of light that passes through the prism is deflected from its original direction, while the angle of deviation of the rays is proportional to the angle of incidence

Abstract

The rapid development of material physics research, particularly in the synthesis and characterization of barium M-hexaferrite (BaFe₁₂O₁₉), has not been optimally integrated into higher education physics learning. At the same time, Project-Based Learning (PjBL) and digital e-modules have been widely reported to enhance students’ creativity, yet their application remains largely limited to basic physics topics. This study aims to map and synthesize existing research related to PjBL-based e-modules, student creativity, and BaM hexaferrite material studies, in order to identify research trends, gaps, and opportunities for interdisciplinary integration. A Hybrid Review methodology was employed, combining a Systematic Literature Review (SLR) guided by PRISMA 2020 and a Bibliometric Review. Literature published between 2018 and 2026 was collected from Scopus and SINTA databases. A total of 38 eligible articles were included for qualitative synthesis and bibliometric mapping. The SLR examined research focus, methodologies, learning outcomes, and material synthesis approaches, while the bibliometric analysis explored publication trends, keyword co-occurrence, collaboration networks, and thematic structures. The results indicate that PjBL-based e-modules are consistently effective in fostering creativity and higher-order thinking skills. However, bibliometric evidence reveals a clear separation between physics education research and BaM hexaferrite material studies, with minimal thematic overlap. This finding highlights a significant research gap and underscores the novelty of integrating BaM hexaferrite synthesis and characterization into a PjBL-oriented e-module. The study provides a strong conceptual foundation for developing research-based digital learning materials that promote authentic scientific creativity in higher education physics.
