DETERMINING THE DENSITY AND MOLAR MASS OF AIR IN A HOME EXPERIMENT

Formulation of the problem. Experimental research is an integral part of physics education. During distance learning, students can carry out hands-on experiments only at home. Modern smartphones, equipped with various sensors, offer significant capabilities for this purpose. The literature offers quite extensive descriptions of experiments aimed at determining mechanical, acoustic, and optical quantities using smartphones. At the same time, insufficient attention has been paid to determining gas parameters that can be measured using the pressure sensor embedded in smartphones. Therefore, the relevant task is to develop a methodology for experimenting to determine the density of air and its molar mass at home using a pressure sensor. Materials and methods. To achieve the objective of the study, we used the analysis of the curriculum of the course "General Physics for Bachelor of Engineering", a review of the methodological instructions for performing laboratory work in the section "Molecular Physics and Thermodynamics" of the physics course of technical universities, a review of the literature on the topic of the study, and an analysis of the results of student research on the dependence of air pressure on altitude. We also surveyed students about the possibility of conducting the research at home and their interest in conducting other experiments using a smartphone. Results. The methodology for determining the density and molar mass of air was developed based on the results of a study of the pressure-height dependence. It is shown that it is necessary to perform statistical processing of experimental data to estimate the sought quantities. The experimental results allowed us to obtain values of density and molar mass of air that show a good correlation with the tabulated values. Conclusions. Studying the pressure-altitude relationship using a smartphone and the PhyPhox application allows for fairly accurate calculations of air density and molar mass. According to the survey results, students responded positively to conducting home experiments using smartphones.

Energy as a source of preservice teachers’ conceptions about radioactivity

Although researchers have extensively studied student conceptions of radioactivity, the conceptions held by preservice teachers on this subject are largely absent from the literature. We conducted a qualitative content analysis of problem-centered interviews with preservice teachers (N=13) to establish which conceptions are held by preservice teachers and to examine these conceptions’ structure in coordination classes. As has already been observed in students, some preservice teachers inadequately differentiate between radioactive matter and ionizing radiation and between fission and decay. We also observed that preservice teachers tend to describe the activation of materials due to ionizing radiation despite having previously denied an activation, thus showing that the conception of activation of materials can reemerge in particular framings. Within the interviews conducted, the concept of energy emerged as a central coordination class regarding radioactivity. This coordination class appeared across contexts and proved fruitful in explaining preservice teachers’ conceptions about radioactivity. We will use the results from this study to develop a teaching-learning laboratory for preservice teachers in which they can actively study high school students’ conceptions while reflecting on their own. In this way, these findings will contribute to improving the structure of nuclear physics courses at the university. Published by the American Physical Society 2024

Enhancing University Students' Motivation in Basketball Courses through Tactical Games Model.

As the COVID-19 pandemic subsides, universities face challenges such as diminished student physical fitness and a decreased interest in physical education courses. The purpose of this study was to evaluate the effectiveness of the tactical games model (TGM) in enhancing university students' motivation in basketball courses, using a comparison control group taught using the direct instruction model (DIM). Additionally, this research delves into the motivational dynamics explained by self-determination theory, aiming to identify key factors influencing student engagement and participation. A total of 141 sophomore university students were analyzed and divided into an experimental group (68 students) and a control group (73 students). The participants engaged in an 8-week teaching intervention program. To assess motivation, the Sport Motivation Scale-II (SMS-II) was administered both before the start and one week after the conclusion of the intervention. Differences in motivation and subscale scores between the TGM and DIM groups were evaluated using analysis of variance (ANOVA) and analysis of covariance (ANCOVA). The results of the study demonstrated that the TGM significantly enhanced university students' motivation (SDI: F = 6.949; p = 0.009; η² = 0.049). Furthermore, TGM enhanced scores on intrinsic and extrinsic motivation sub-scales more effectively than the DIM. These findings advocate for the adoption of TGM by university instructors as a potent tool to elevate student motivation, emphasizing the importance of focusing on both intrinsic and extrinsic motivational elements within physical education programs.

Promoting Youth Participation in Sports: An Analysis of Home-School-Community Approach

Young people are the future of the country and the hope of the nation. The physical health of adolescents plays a vital role in their growth. Regular sports participation can effectively improve the physical health of teenagers, while also helping to improve mental health and promote emotional regulation, thereby helping teenagers thrive and achieve the educational purpose of all-round development. The purpose of this study is to promote youth sports participation. Based on the ecological system theory, overlapping influence domain theory, and synergy theory, three environments, namely family, school, and community, which are closely related to the healthy growth of teenagers, are selected to analyze the impact of youth sports participation. factor. By summarizing the literature and expert guidance, 11 factors were identified at three levels that affect youth sports participation: the family level includes parental cognition, parental support, and parent involvement; the school level includes leadership support, teacher ability and cognition, campus facility funds, Physical health courses, campus sports atmosphere; community level includes organizational management, sports resources, publicity and education. This study adopted a random sampling method and selected 390 students from 10,242 students in 3 middle schools in Zhanjiang City as survey subjects. The researchers collected data through questionnaires that included participants' demographic profiles, sports participation, family factors, school factors, and community factors. Data were interpreted and analyzed using frequencies, percentages, weighted averages, Likert scales, Pearson correlation analysis, and linear regression analysis. Research shows that there are significant differences in youth sports participation by gender and grade. Boys' sports participation is better than that of girls. The sports participation status of junior middle school students is better than that of high school students. Among the effects of family factors on youth sports participation, "parental cognition", "parental support" and "parental participation" can all have a significant positive impact on youth sports participation. It shows that family entities can promote adolescents' sports participation behavior from three aspects: improving "parental awareness", focusing on "parental support", and focusing on "parental participation". In the impact of school factors on youth sports participation, in addition to "leadership support", the other four dimensions in the school factor scale are "teacher ability and cognition", "school facility funding", "physical education and health curriculum" and "school "Sports atmosphere" can significantly and positively affect youth sports participation, indicating that schools need to optimize hardware facilities, introduce outstanding sports talents, design sports and health courses, and create a good sports atmosphere in schools as the main ways to promote youth sports participation. Among the effects of community factors on youth sports participation, "sports resources" and "publicity and education" can both significantly and positively affect youth sports participation. However, "organizational management" cannot directly affect youth sports participation. Therefore, we can focus on absorbing and receiving more community sports resources, vigorously promoting sports-related information, creating a good sports atmosphere, and attracting more young people to participate in sports.

Neurorehabilitation in a Pediatric Stroke Patient Supported on a CentriMag.

Patients supported on ventricular assist devices (VADs) benefit from rehabilitation while awaiting heart transplantation to recover from surgery, prevent deconditioning, and, in most cases, optimize transplant candidacy. With bleeding and neurological dysfunction as the most common VAD complications, the importance of rehabilitation dramatically increases when a patient on a VAD also suffers from a neurological injury. The rehabilitation needs for cardiac conditioning and neurological reeducation are not the same. Patients with severe neurological deficits require intense rehabilitation that often includes base-of-support challenges, usage of bolsters and balls, partial weight-bearing treadmill training, and assumption of various body positions in prone, kneeling, or quadruped for neuromotor reeducation. However, some devices are more conducive to rehabilitation than others. For children supported by the CentriMag in particular, rehabilitation is challenged by short cannula tubing, an external motor, a large interface, and an intensive care unit (ICU) admission. We report a safe and successful physical therapy course of a pediatric stroke patient with a diagnosis of Ebstein's anomaly supported by a CentriMag right VAD (RVAD) while awaiting heart transplant in the ICU.

Shooting stars on schedule: synchronising re-entry of particles launched from a satellite

The ALE-3 mission plans to create artificial ‘shooting stars’ in the upper atmosphere by launching pellets sequentially from a satellite in low Earth orbit. How does one arrange for all pellets to re-enter over the intended location simultaneously? Starting with conservation of energy and angular momentum, I derive a version of Kepler’s equation that gives time as a function of radial distance in an orbit, which can be used to find the transfer time from the pellet’s ejection to its re-entry as a function of its launch velocity. I show that for a given pellet ejection speed, there is a launch angle from the satellite that results in the fastest transfer time. I use these results to determine the pellets’ launch times and velocities for simultaneous arrival at a desired re-entry point. These results can be applied to de-orbiting any set of objects launched from a satellite, and use concepts that can be covered in an advanced undergraduate course in physics or aerospace engineering.

The effects of active learning on students’ sense of belonging and academic performance in introductory physics courses

Research-based active learning strategies have been shown to have positive effects on students’ learning in physics class. However, the exploration of active learning’s impact on students’ sense of belonging in physics classrooms remains limited. In this paper, we present our findings pertaining to students’ sense of belonging in an introductory physics course at a large public research university. This course was taught by three different instructors, one of whom integrated research-based active learning strategies, while the other two employed traditional lecture-based approaches. Our results show a statistically significant decrease in the sense of belonging among students in the traditionally taught classes, in contrast to a modest increase in students’ sense of belonging in the active learning class. Furthermore, we observed a statistically significant gender difference in students’ sense of belonging at the beginning of the course, which was closed by the end of the active learning class but persisted in the traditional classes. In addition, the active learning class exhibited a positive impact on students’ academic outcomes, and this effect was partially mediated by the sense of belonging. Our findings indicate that active learning classes, particularly those thoughtfully designed to foster inclusive environments, may benefit students’ sense of belonging and enhance their academic performance without relying on the use of specific belonging interventions.

Analysis of Quantum Physics Lectures from the Perspective of the MBKM and OBE Based Higher Education Curriculum

Lecture analysis in the core courses of the study program contributes to the evaluation of the curriculum used. This field study was carried out to analyze Quantum Physics lectures from the perspective of a university curriculum based on Independent Learning Campus (MBKM) and Outcome-Based Education (OBE). Data collection techniques were carried out through observing the implementation of learning in the Quantum Physics course, interviews with lecturers teaching quantum physics courses, and reviewing curriculum tools in the form of curriculum books, semester lecture plans (RPS), and assessment documents. The instruments used refer to content standards, process standards and learning assessment standards listed in Permendikbud Number 3 of 2020, Permendikbudristek Number 56 of 2022, and Permendikbudristek Number 53 of 2023. The participants involved in this research were a lecturer and 29 students of the undergraduate physics education study program at one of the universities in Garut Regency. The lecturer in question is a lecturer who teaches quantum physics courses, while the students in question are final year students who are taking quantum physics courses in the odd semester of the 2023/2024 academic year. Data collection was carried out over the period October – November 2024. Data analysis was carried out qualitatively using a data triangulation approach. The results of data analysis show that in the Bachelor of Physics Education curriculum, the Quantum Physics course is in the group of upper-level compulsory courses with physics concept study material. From an MBKM perspective, this course can be converted to Program Pertukaran Mahasiswa (PMM) and Program Magang dan Studi Independen Bersertifikat (MSIB), but cannot be converted to the Teaching Campus Program. Conversion to the PMM program is carried out by taking courses in other study programs that have course learning outcomes that are related to quantum physics. Conversions to the MSIB program are carried out at companies or agencies related to the application of quantum physics concepts. From an OBE perspective, this course contributes to graduate learning outcomes in Specific Skills and supports the graduate's profile as a Physics Teacher.

Association between physical activity and functional movement screening among university students in an adaptive physical course.

Physical activity (PA) holds profound implications for the holistic development of college students. However, students with chronic diseases or physical disabilities experience significantly limited PA during adaptive sports. This study aims to investigate the relationship between physical activity and Functional Movement Screening (FMS) among university students who participate in the adaptive physical course. 36 university students (from the adaptive physical course) completed the International Physical Activity Questionnaire-Long Form (IPAQ-L). Body measurements and FMS were assessed. Correlation analysis and t-tests were used to determine relationships and differences between various indicators. A two-way analysis of variance was used to investigate potential variations in FMS scores based on gender and weight status. The results show that gender, PA, and BMI significantly influence FMS scores in students participating in adaptive physical courses. FMS score is significantly negatively correlated with BMI and significantly positively correlated with PA. The FMS score for males, as well as the scores for Trunk Stability Push-Up and Rotary Stability, are significantly higher than those for females. University students in adaptive physical courses can benefit from increased PA and FMS scores. Improving functional movement and enhancing physical activity are crucial for promoting overall health in this population.
