A Study on the Effect of Power on the Passing Success of Youth Football Players

Wanchat Suwanprasert — 2025-06-30

This study aimed to investigate the effect of work power utilized during passing on the passing success rate of youth football players. A Python-based video analysis technique was employed in combination with physics-based calculations performed using Microsoft Excel. The sample consisted of 22 male youth football players from the Jaifa Football Academy, Lopburi Province, Thailand. Data were analyzed using descriptive statistics, one-way analysis of variance (One-Way ANOVA), Pearson’s correlation analysis, multiple regression analysis, and effect size calculations, including η² and R² values. The results indicated that the work power exerted during passing did not significantly influence the number of successful passes (p = 0.58), although the effect size (η² = 0.143) suggested a moderate level of influence. Conversely, speed was found to have a statistically significant positive correlation with passing success (r = 0.55, p = 0.004) and emerged as a strong predictor of performance outcomes (β = 2.65, p = 0.002, R² = 0.62). These findings highlight that player speed plays a more critical role in successful passing performance than the amount of work power applied.

Physics model for calculating the stopping distance of a moving object in friction surface using simple pendulum motion

Artit Hutem — 2025-06-30

The purpose of this research is to create a model for calculating the stopping distance of a moving object in the friction surface using simple pendulum motion. In this research, there are three types of objects moving in the friction surface : rectangular, hollow, and solid spheres. Using the simple pendulum movement of objects colliding with objects moving in the friction surface, all 3 types, then using the law of conservation of momentum. and work and energy theory. In this research, we want to calculate the stopping distance of a moving object in the sand and relate it to the coefficient of friction.

Development of a Chemical Inventory Management System in Science Laboratories

Jumroon Chankulchorn — 2025-06-30

Chemical management in science laboratories plays a crucial role in enhancing the effectiveness and safety of both teaching and research activities. However, manual or semi-automated data recording methods often face challenges in terms of accuracy, timeliness, and the risk of using expired chemicals. Furthermore, the lack of integrated data hinders decision-making for the proper disposal of expired or unused chemicals. This study aims to develop a chemical inventory management system for science laboratories. The system is designed as a web application to manage chemical information and disbursement processes within the Chemistry, Biology, Physics, and Environmental Science laboratories of the Faculty of Science and Technology, Uttaradit Rajabhat University. The developed system features real-time chemical inventory tracking, automated alerts for low stock levels and approaching expiration dates, role-based access control, and report generation tools that support efficient and sustainable chemical disposal planning. The system was built using a Module-Model-View-Controller (MMVC) architecture on the Kotchasan PHP Framework, integrated with a MySQL database. This architecture enables comprehensive chemical inventory management, including chemical intake, disbursement, usage tracking, and reporting. The user satisfaction assessment, conducted with a sample group of 40 participants comprising lecturers, staff, and students, revealed a very high satisfaction level, with an average score of 4.63 and a standard deviation of 0.61. This indicates that the developed system possesses strong potential to enhance the efficiency of chemical inventory management in science laboratories, improve safety, and support sustainable resource management.

Study on the Optimal Proportion in the Production Process of Starfruit Craft Soda

Wachira Singkong — 2025-06-30

This research aims to study the production process of craft soda from starfruit and analyze its quality. The analysis of the physical and chemical characteristics of three commercial fruit craft soda brands, along with a sensory evaluation for consumer preference, revealed that sample B had the highest overall preference. Sample B also had the highest total acidity at 1.54% and the highest total soluble solids at 8.70 °Brix. The study on the optimal ratio of starfruit in the production process and the evaluation of the characteristics of the starfruit craft soda found that the formulation with the highest starfruit-to-sugar ratio (125:175 grams) received the highest overall preference score of 7.13. This formulation had the lowest total acidity at 0.8% but the highest total soluble solids at 15.4 °Brix. When compared to sample B, the craft soda shows similar values in pH and color parameters L*, a*, and b*. All craft soda samples meet the community product standard (TIS 2/2546).

The Effects of CIPPA Model Learning Management Combined with Computer-Assisted Instruction Lessons on Academic Achievement in Chemistry: Solutions for Mathayom 4 Students at Pangsilathongsuksa School, Kamphaeng Phet

Phurichaya Kroisanoi — 2025-06-30

The purposes of this research were to study the effects of CIPPA model learning management along with Computer-Assisted Instruction (CAI) lessons on academic achievement in Chemistry: Solutions and to study satisfaction level of students after studying through the CAI lessons. The participants of this research were Mathayom 4 students who studied in the second semester of the academic year 2024 at Pangsilathongsuksa School. They were selected using cluster random sampling. These students were divided into two groups: 38 students were put in an experimental group, and 39 students were in a control group. The research instruments included CAI lessons, lesson plans using the CIPPA model learning management combined with CAI lessons, lesson plans using the CIPPA model learning, a Chemistry: Solutions achievement test, and a satisfaction questionnaire. The data were analyzed using mean, standard deviation, and independent and dependent t-tests. The research results showed that the computer-assisted instruction lessons in Chemistry: Solutions had an efficiency E1/E2 of 80.26/80.53. The level of satisfaction of the students with the CAI lessons was at a high level (= 4.34, SD = 0.69). The academic achievement of students who received CIPPA model learning management combined with CAI lessons was significantly higher than that of students who received only CIPPA model learning management, at the 0.05 level of statistical significance.

The Effects of Learning Activities Using GeoGebra on Fundamental Geometric Constructions for Grade 7 Students at Thepsatri Rajabhat University Demonstration School

Ashiraya Deengam — 2025-06-30

This study aimed to investigate the learning achievement and satisfaction of Grade 7 students who participated in a learning approach using the GeoGebra program on fundamental geometric constructions. The sample consisted of 49 Grade 7 students from Thepsatri Rajabhat University Demonstration School, who were taught using GeoGebra over a specific period. After the learning process, pre-test and post-test assessments were conducted to measure students' learning achievement, along with a survey to evaluate their satisfaction.

The findings revealed that students' learning achievement significantly improved after using GeoGebra, with the average post-test score increasing from 4.92 to 11.16. Furthermore, students' satisfaction with the GeoGebra-based learning approach was at a very high level (mean = 4.67, S.D. = 0.51). These findings suggest that incorporating the GeoGebra program into geometry instruction can effectively enhance students' understanding and learning outcomes.

The Guideline for Developing Mathematics Learning Activity on Exploring Logarithm with Logarithm Ruler

Pamornmate Laohawiroongool — 2025-06-30

Teaching Mathematics on Upper Secondary Level is necessary to make student obviously understand because the contents on this level is too abstract. They make students do not understand, cannot apply the concept in real world situation and dislike mathematics eventually. Logarithm is one of abstract contents so teacher should teach this content substantially. Using the logarithm ruler is a good way to applicate in the class. It’s useful for learning activity and make student can find the value of logarithm easily.
