Perceptions of Students Towards The Scientist-Teacher-Student Partnership (STSP) in Medical Physics Subjects
Full text linkMedical Physics is a branch of physics application that is developing very rapidly. Therefore, the contextualization of Medical Physics is crucial for future physics teachers. This research aims to implement Student-Teacher-Scientist Partnerships (STSP) in Medical Physics and explore students\u27 perceptions of the learning experience through this program. STSP in this research involved prospective physics teachers as students, lecturers in medical physics courses as teachers, and medical physicists as scientists. The benefits of this research are to provide a learning experience of medical physics directly from experts (medical physicists) as a provision for prospective physics teachers to strengthen their knowledge of medical physics content and how to teach it, and to be a recommendation for learning strategies that support contextual physics learning. Implementing STSP in medical physics courses includes planning, implementation, and evaluation activities for one semester of lectures; lectures by the foremost scientists were held in 7 meetings (1 meeting = 2 x 60 minutes). The planning stage includes activities to equalize perceptions between scientists and related lecturers. The course was primarily student-centred, with case study discussions conducted online via Zoom meetings. The scientists were located in East Java Province, Indonesia, while the teachers and students were in East Kalimantan Province, Indonesia. The evaluation stage was carried out by exploring students\u27 perceptions of the program implementation, the results of which can later be used as a reference for the continuation of the program implementation. Results indicated that STSP activities facilitated easier comprehension of medical physics, increased interest in further study, and highlighted connections between course topics and secondary school curriculum.
Teaching and Learning Hooke’s Law Using Physical, Interactive Software and Blended Approach: An Overview
Full text linkAt present, with technological advancement and changes in students’ preferences, there are both challenges and opportunities to enhance the teaching and learning of subjects in science, technology, engineering, and mathematics (STEM). In this article, we explore reported works in established databases on the topic of Hooke’s Law, to see the approaches used in teaching and learning of the topic. Searches were performed in Web of Science, Scopus and Google Scholar databases, after which manual filtering for relevant articles was carried out by reading and browsing through the abstracts. Based on the types of works, the articles were separated into three parts: physical, interactive software, and blended. In total, 21 relevant articles were reviewed. The data obtained can be separated into three categories: physical, interactive software, and blended. Of the three, blended approaches were used the least. To further explore the topics discussed in the articles related to Hooke’s Law, a bibliometric study was performed. From the results, we found that, with the advantages offered by the blended approach, and none using artificial intelligence, there is still room for improvement to enhance the teaching of Hooke’s Law, specifically, and generally, on introductory physics subjects

The Effect of Problem-Based Learning Model on Mathematical Problem-Solving Ability in Term of Gender Differences of Students
Full text linkThe ability to solve mathematical problems is the main objective in mathematics learning, therefore problem-solving should be taught to students as early as possible, practiced, and used not only in mathematics learning, but also in everyday life. TIMSS results indicate that Indonesian eighth-grade students\u27 ability to solve non-routine problems (mathematical problems) is very low, but they perform relatively well in solving factual and procedural problems. This study examined the effect of Problem-Based Learning (PBL) model on mathematical problem-solving ability (MPSA) in terms of gender differences of students in class IX. This research is pseudo-experimental research with non-equivalent control group design. The population in the study were all students of class IX which amounted to 175 students, ranging from class IX.1 to IX.5. The sample in the study was taken by purposive sampling method, so that class IX.4 which amounted to 33 students as the experimental class and class IX.5 which amounted to 33 students as the control class. Data collection techniques were carried out using test techniques with MPSA test instruments in the form of pre-test and post-test. Data analysis techniques used are descriptive analysis and inferential analysis. The results showed that: a) there was a difference in the average MPSA of students in terms of the learning model used (0.000 < 0.05), b) there was a difference in the average MPSA in terms of the gender of students (0.001 < 0.05), and c) there was no interaction between the gender of students and the learning model used on the problem-solving ability used (0.899 > 0.05. It can therefore be concluded that the PBL model has an effect on MPSA when viewed from the perspective of gender differences among students.

Sehingga dapat disimpulkan bahwa terdapat pengaruh model PBL terhadap kemampuan pemecahan masalah matematis ditinjau dari perbedaan gender peserta didik
Perceived Environmental Knowledge and Ease of Use: Keys to Increasing Purchase Intention of Sustainable Packaging
Full text linkIn the modern era, environmental issues have become a global concern due to the rising impacts of pollution and climate change. One solution is sustainable packaging to reduce waste and environmental damage. This study examines the relationship between environmental awareness, perceived environmental knowledge, perceived ease of use, and purchase intention, with trust in sustainable packaging as a mediating variable. The novelty lies in adding trust in sustainable packaging and utilizing local potential, namely lontar materials, as eco-friendly alternatives to recycled cloth, paper, and plastic. Using the Theory of Planned Behavior, a quantitative approach, and purposive sampling, the study collected 192 samples, with 170 valid responses. Results show that purchase intention is influenced by trust in sustainable packaging, environmental awareness, environmental knowledge, and ease of use. Trust is shaped by environmental awareness, environmental knowledge, and ease of use. Trust mediates the effect of environmental knowledge and ease of use on purchase intention but does not mediate the effect of environmental awareness. These findings are valuable for producers using lontar-based packaging, suggesting they target environmentally conscious consumers who value knowledge and usability

Administering moringa leaf extract capsules fortified with royal jelly presents a viable intervention to alleviate this stress. This study investigates the specific effects of these capsules on cortisol and stress levels in pregnant women. The study was conducted as a true experimental, single-blind, randomized controlled trial involving 61 pregnant women. The intervention group (n = 31) received moringa leaf extract capsules enriched with royal jelly, while the control group (n = 30) received multi-micronutrient supplements. The findings revealed a noteworthy reduction in cortisol levels within the intervention group (p = 0.030), from 26.61 ± 8.15 to 19.98 ± 14.00, as well as in the control group (p = 0.003), from 21.13 ± 7.76 to 13.26 ± 16.09. Likewise, stress levels exhibited a significant decrease within the intervention group (p = 0.016), decreasing from 18.68 ± 3.74 to 28.75 ± 15.02, and the control group (p = 0.000), declining from 19.17 ± 3.64 to 16.20 ± 3.38. Moringa leaf extract capsules enriched with royal jelly, as a natural remedy, merit the recommendation for inclusion in initiatives to enhance maternal and infant health
The Evolution in The Field of Anticorruption in The Health Sector in Italy
Full text linkThe fight against corruption within the healthcare sector in Italy has undergone significant transformation following the introduction of Law n. 190/2012. This legislation marked a pivotal step towards establishing a comprehensive system aimed at preventing corruption through a blend of preventive measures, transparency, and administrative reorganization. Central to these efforts is the Italian National Anti-Corruption Authority (ANAC) and the National Anti-Corruption Plan (PNA), which provide structured guidelines and strategies for public administrations, including healthcare entities. This study examines the evolution and impact of anti-corruption measures in the Italian healthcare sector, focusing on key legislative and regulatory frameworks, particularly the roles played by ANAC and the PNA. The commentary explores the implementation of these measures, highlighting the innovative approaches and the challenges encountered. Significant milestones include the legislative updates, such as the Legislative Decree n. 231/2001, which introduced administrative liability for corporate crimes, and the more recent resolution n. 605/2023, which reinforces digital procurement processes, real-time data analytics, and enhanced transparency in healthcare administration. These updates align with broader national recovery efforts post-COVID-19 and aim to foster a culture of integrity and accountability within the sector. Key findings reveal that while there has been considerable progress in enhancing transparency and reducing corruption risks, challenges remain. These include resource constraints, complexity of integrating new measures with existing systems, stakeholder engagement, and ensuring rigorous monitoring and enforcement. Addressing these challenges is critical for sustaining the progress achieved and further improving the effectiveness of anti-corruption strategies. The continuous refinement of the PNA and its application within the healthcare sector illustrates a robust commitment by Italian authorities to uphold public trust and prevent corruption
