Abstract

This study investigates the effectiveness of participatory learning combined with a critical problem-solving approach on junior high school students' science process skills in the context of simple machines. Conducted with 61 students from Central Lombok, the research involved an experimental group (31 students) and a control group (30 students). The experimental group received participatory learning treatment with a critical problem-solving approach, while the control group was taught using traditional expository methods. The intervention included three sessions focusing on pulleys, inclined planes, and levers, each lasting 90 minutes. Students' science process skills were assessed across five aspects: preparing practical tools, assembling practical tools, reading measurements, collaborating with peers, and conveying information. The results revealed that the experimental group significantly outperformed the control group in all aspects of science process skills, with higher mean scores and lower variability. The findings indicate that participatory learning with a critical problem-solving approach is more effective than traditional methods in enhancing students' science process skills. This study's outcomes suggest that integrating interactive and student-centered approaches in science education can foster critical thinking, collaboration, and practical application of scientific concepts. The research contributes to the existing literature by demonstrating the benefits of combining participatory learning and critical problem-solving in teaching complex topics like simple machines. Future research should explore the long-term effects of these approaches and their applicability across various educational contexts and subjects.

Abstract

Barium hexaferrite (BaFe12O19) is a material of significant interest due to its wide range of applications. In this study, we synthesized barium M-hexaferrites (BaFe12-2xCoxZnxO19) powders through the co-precipitation method, starting from BaCO3 and FeCl3.6H2O powders, with Co and Zn powders used as dopant materials. The variations in x values were set at 0, 0.2, 0.4, 0.6, 0.8, and 1. Our findings indicate that the co-precipitation method is highly effective for synthesizing barium M-hexaferrites (BaFe12-2xCoxZnxO19) nanomaterials, which contain more than 89% iron elements and have an average particle size of 50 nm. The Differential Thermal Analysis (DTA) and Thermogravimetric Analysis (TGA) reveal that phase transformations occur at temperatures of 285°C and in the range of 750-840°C. Further analysis using the Rietveld refinement method demonstrates that the barium M-hexaferrite phase begins to form at relatively low temperatures, with the most optimal yield observed at x = 0.4. At temperatures exceeding 740°C, there is a tendency to form a single-phase α-Fe2O3 (hematite). The introduction of Co and Zn as dopant ions results in only minor changes to the lattice parameters of the basic hexagonal crystal structure. This comprehensive study underscores the viability of the co-precipitation method for producing high-quality barium M-hexaferrites and provides valuable insights into the effects of Co and Zn doping on the structural and thermal properties of these materials.

Abstract

This study delves into the design thinking characteristics among students in the field of information technology innovation, examining their competencies within the context of the Information Technology Education program at Mandalika University of Education - Indonesia. Employing an exploratory descriptive research design, the research focuses on 30 students, utilizing the Design Thinking Scale to assess six crucial dimensions: comfort with uncertainty and risks, human-centeredness, mindfulness of the process and impacts on others, collaborative work with diversity, orientation to learning by making and testing, and confidence and optimism to use creativity. The findings reveal a comprehensive understanding of the nuanced aspects of students' design thinking capabilities, indicating areas for improvement. Notably, students exhibit discomfort with uncertainty and risks, signaling a need for interventions to enhance resilience and adaptability. Human-centeredness, collaborative work with diversity, and mindfulness to the process receive "Poor" and "Fair" ratings, emphasizing the importance of fostering user-centric approaches and enhancing collaborative competencies. While students demonstrate a moderate level of competency in practical learning and creative application, there is room for improvement in orientation to learning by making and testing and confidence and optimism to use creativity. The overall "Poor" rating for the average design thinking score suggests a collective need for targeted interventions and educational strategies. This study contributes to the ongoing discourse on design thinking in IT education. It offers insights that can inform tailored pedagogical approaches and interventions to enhance students' design thinking capabilities in preparation for the dynamic challenges of the evolving information technology landscape.

Abstract

The integration of artificial intelligence (AI) tools in physics education is gaining traction, driven by their potential to enhance learning experiences and outcomes. This study aims to investigate the use of AI tools, particularly ChatGPT, in solving physics problems and enhancing educational practices. Utilizing a systematic literature review following PRISMA guidelines, the research identifies current trends and practical applications of AI in physics education. The results indicate that AI tools effectively support lesson planning, introduce innovative teaching methodologies, and assist in solving complex physics problems, significantly enhancing problem-solving skills and personalized learning experiences. However, challenges such as inaccuracies in handling advanced content, the lack of useful visual aids, and the need for human intervention to ensure the completeness and accuracy of AI-generated content were noted. Personal experiences, supplemented by an interview with a thermodynamics lecturer, revealed that while ChatGPT can simplify complex concepts and improve comprehension, it could not replace the mentorship and nuanced feedback provided by human educators. The study concludes with recommendations for integrating AI tools into physics education, emphasizing the need for balanced integration with traditional teaching methods, improved AI literacy among educators and students, and future developments focusing on personalized learning and enhanced visualization capabilities. The findings demonstrate the transformative potential of AI in physics education and highlight the importance of addressing its limitations to maximize educational outcomes.

Abstract

The primary objective of this study is to investigate the optical properties of polyvinyl alcohol (PVA) based polymer films, incorporating methylene blue (MB) dye and trichloroacetic acid (TCA), for their potential application in gamma radiation dosimetry. Specifically, this research aims to explore the effects of gamma radiation on the color change characteristics, optical absorption spectra, activation energy, and optical band gap energy of the PVA-MB-TCA polymer films. Additionally, the study seeks to assess the stability of these polymer films under varying doses of gamma radiation, ranging up to 14 kGy. The PVA-MB-TCA polymer films were prepared using a solvent-casting method. The polymer film samples were then exposed to gamma radiation from a 60Co source, with doses up to 14 kGy. The study observed significant color changes in the polymer films, transitioning from blue at 0 kGy to light blue-near transparent at 14 kGy. Spectrophotometric analysis identified three distinct wavelengths of maximum absorption at 360 nm, 440 nm, and 560 nm. As the radiation dose increased, absorption values decreased at 360 nm and 440 nm, while an opposite trend was noted at 560 nm. Furthermore, the activation energy of the polymer films was found to decrease with increasing radiation doses, indicating a reduction in the energy barriers for internal reactions. Similarly, the optical band gap energy also showed a decreasing trend with higher radiation doses across all types of transitions. These results demonstrate that the PVA-MB-TCA polymer films undergo significant optical and structural changes when exposed to gamma radiation, highlighting their potential utility as reliable high-dose radiation dosimeters. The stability of these films under radiation further supports their applicability in various fields requiring precise radiation dose monitoring, such as medical sterilization, food processing, and environmental safety.
