Enhancing Physics Experience: VIRRE (Virtual Reality of Renewable Energy) to Increasing Concept Understanding and Learning Motivation in Secondary Education

2024-09-30T19:13:20+07:00

This research aims to develop VR in renewable energy materials (VIRRE) to increase students’ concept understanding and learning motivation. This research used Research and Development (R&D) method through ADDIE development model. Validation was carried out to determine the feasibility of VIRRE, then implemented in secondary school students by using problem-based learning model throughout three meetings. Research data was collected through questionnaires and pretest-posttest during classroom learning. The results show that VIRRE has a validity percentage of 94.07% with very valid criteria. The effectiveness of VIRRE media in increasing students' concept understanding and learning motivation is included in medium criteria with n-gain scores of 0.52 and 0.33 respectively. Additionally, VIRRE usage in learning activities showed the most improved indicator of concept understanding and aspect of learning motivation, namely classifying and self-confidence respectively. Moreover, the result indicates that both concept understanding and learning motivation are related to each other, once students are motivated to learn the subject, they can achieve a great understanding of its concept. VIRRE received very good responses from students in aspects of learning activities, materials, and media use with average percentages of 82.22%, 82.7%, and 84.23% respectively. Thus, VR could be an alternative media learning to support educators in delivering physics materials, which are viewed as complicated concepts according to the students.

Understanding Newton's Third Law: A Study of Prospective Physics Teachers' Knowledge Structure

2024-09-30T19:13:28+07:00

This research aims to explore the ability to understand concepts and the characteristics of the knowledge structure of prospective physics teachers regarding Newton's Third Law. This research was conducted on 26 Physics Education students in their first year who had received material on Newton's Laws. The instrument used is the Force Concept Inventory (FCI) test instrument. Using four multiple-choice questions accompanied by reasons, the quantitative data source comes from students' choice of answers. In contrast, the qualitative data source comes from students' reasons for choosing answers, which are used to see the characteristics of knowledge structures. The data analysis technique used is descriptive statistics to present a picture of the ability to understand concepts and the level of character of the knowledge structure of prospective teachers. The results show that the concept understanding ability of prospective physics teachers has an average of 67.31 and is classified as sufficient. The knowledge structure characteristics of prospective physics teachers at the expert level is 62.50%, the beginner level is 14.42%, and the intermediate level is 24.04%. These results show that the ability to understand the concept of Newton's Third Law and the characteristics of knowledge structures have a coherent influence. Prospective teachers with the characteristics of an expert knowledge structure can solve physics problems using correct physics principles. These findings require further research to explore the factors influencing understanding concepts and characteristics of prospective teachers' knowledge structures and more effective teaching strategies.

Development of Student Worksheet Integrated by Differentiated-PjBL Model to Train Student Science Process Skills on Renewable Energy Material

2024-09-30T19:13:25+07:00

This study is a research and development (R&D) to produce student worksheets that integrate the project-based learning model and a differentiated approach to train students' science process skills on renewable energy material. The development model used in this study is the ADDIE development model, namely analysis, design, development, implementation, and evaluation. This study aims to determine the feasibility and practicality of student worksheet products. Five expert validators conducted the product feasibility test, resulting in a score of 0.88 with valid criteria. Teachers and students carried out the product practicality test as users of student worksheets. The teacher's practicality test obtained an average score of 92.08% with very practical criteria, while the student's assessment obtained an average score of 86.95% with very practical criteria. Based on the feasibility and practical test results, the student worksheet products are feasible and practical for use in learning to train students' science process skills.

Feasibility Of Digital Flipbooks as Physics Teaching Media in Terms of Reproduction

2024-09-30T19:13:23+07:00

Various media that utilize technology in implementing teaching materials make the teaching-learning process more innovative and increase students' curiosity. This study aims to develop and validate a digital flipbook for physics education, focusing on reproduction topics. This study applied the research and development (R&D) design using the 4-D model, which consists of define, design, develop, and disseminates. This study is only up to the validation stage and revision of the validation results. The validation subjects in this study are 16 people. The result shows that the developed media is valid, totaling 97.51%. This learning media will be very helpful for students to better understand the understanding of physics in the application of everyday life, namely in the reproductive system. The feasibility instrument for digital physics flipbooks in reproduction developed can also be a reference for teachers to research the feasibility of other learning media. The digital flipbook of physics in reproduction is expected to be further developed in further research, namely in the implementation stage, to test its effectiveness in the science learning process.
