Volta Drive Connect: Science Kit to Stimulate the Elementary Students in Sustainable Development

Khaerini Rahmania — 2024-09-02

The goal of this research is to develop the Volta Drive Connect science kit to increase energy literacy and inspire students to play a role in sustainable development. Volta Drive Connect consists of three levels with different components and levels of assembly difficulty. The research methodology uses developmental research with the ADDIE model (Analysis, Design, Development, Implementation, and eval__uation). The analysis phase involves the identification of learning needs and student characteristics. Instruments used are performance rubrics, observations, interviews, and documentation. The eval__uation of the effectiveness of the teaching kit was carried out using a paired samples test comparing student learning outcomes before and after using Volta Drive Connect. The test results show a significance value of 0.000 (p < 0.05), indicating a significant difference between the pre-test and post-test. Students' energy literacy increased significantly between before and after implementing Volta Drive Connect. Qualitative analysis of observation and interview data revealed increased learning motivation and student engagement during the use of the kit. Minor technical challenges identified during implementation were noted for improvement in future iterations of the kit. The development of Volta Drive Connect was successful in creating a learning medium that is effective in increasing energy literacy, and aligned with the goals of the SDGs.

Enhancing Students’ Concepts Mastery in Kinetic Theory of Gases Through the STEM-Discovery Learning Model

Shinta Dewi Susanti — 2024-09-07

Students' difficulties with gas kinetic theory material have led to low mastery of physics concepts. Improving mastery of the concept of the kinetic theory of gases can be supported by using learning models. There have been many studies that prove that discovery learning can influence physics learning outcomes. However, this study uses a STEM approach integrated into a discovery learning model that acts as part of the inquiry level in physics classes Merdeka curriculum. This research aims to improve students' mastery of concepts in the kinetic theory of gases material through the STEM-discovery learning model. This research used a one-group pretest and posttest design on 30 students of class XI Merdeka 4 at SMAN 1 Dolopo. The instruments used are the RPP and five questions describing the concept mastery test. The data obtained was then analyzed using the normality test, difference test, N-gain, and effect size, and categorizing the students' concept mastery level for each question. The results of this research reveal that STEM-discovery learning is able to increase students' mastery of concepts in kinetic gas theory material. Interestingly, this research also found that students' correct conceptions have not been able to be stored in memory very well, so it is necessary to link kinetic gas theory material to other physics material that is still relevant so that students are motivated to remember and retain concepts.

Needs Analysis of Implementation of The Mentoring Program for Fundamental Physics 1 Lectures to Support Student Learning Independent

Muhammad Reyza Arief Taqwa — 2024-09-10

This research uses a descriptive method and aims to analyze the need for a mentoring program in the Fundamental Physics I course. The research was conducted on 64 students (32 students had participated in the mentoring program for one semester, and 32 students did not participate in the mentoring program), 2 lecturers, and 4 tutors. Data were obtained from documents of students' final exam scores, interviews, and surveys. The results showed that (1) the final exam scores of students who participated in the mentoring program were better and significantly different from the class that did not participate in the mentoring program, (2) students who participated in the mentoring program gave a positive response to the program, and (3) students who did not participate in the mentoring program felt that they experienced many difficulties in Fundamental Physics I lectures and felt that the mentoring program was necessary.

Development of Practicum Tools for Learning the Concept of Light Interference Assisted by the ESP-32 Camera Sensor to Practice Science Process Skills

Dita Shanda Putri — 2024-09-11

This research aims to develop a practicum tools with assisted by the ESP-32 camera sensor which can be used in learning the matter of light interference at school, as well as to train science process skills. This research uses a Design and Development Research (DDR) approach, which is divided into three stages, that are analysis, design and development, and eval_uation. Before this practicum tool is used in the field to help the learning process, this practicum tool is tested for feasibility first. The feasibility test of the practicum tools for the matter of light interference was carried out using a validity test and practicality test. The results of the practicum tools validity test obtained a percentage of 86% with a very valid category and the indicator for the usefulness of practicum tools in science process skills was 81%. The results of the practicality test obtained a percentage of 84% in the very practicality category. Based on these two feasibility tests, it can be concluded that the practicum tool is suitable for use in learning the matter of light interference at school, and can train students' science process skills. Indicators of scientific process skills that are trained are observing, communicating, controlling variables, hypothesizing, experimentation, and interpreting data.

Implementation of ICT-based Inquiry Learning Model for Enhancing Critical Thinking Skills in Mechanical Waves Characteristics

Sari Yunita — 2024-09-17

Critical thinking skills are essential in 21^st century education. However, students’ critical thinking skills remain underdeveloped. To align with contemporary advancements, curricula now demand integration with 21^st century skills, including critical thinking and technology. This study aims to investigate the implementation of ICT-based inquiry learning model for enhancing critical thinking skills in mechanical wave characteristics. This study employed a pre-experimental research method, utilizing a one-group pretest-posttest design. The participants consist of 34 eleventh-grade students from a high school in Bandung district, selected through convenience sampling. The instruments used were critical thinking skills test. The improvement of critical thinking skills was analyzed using N-Gain. The results showed that students’ critical thinking skills increased an average N-Gain value of 0.35 in a moderate category and there is a significant difference between the pretest and the posttest shown by the Wilcoxon signed rank test, which is p value < 0.05. Thus, the ICT-based inquiry learning model can enhance students’ critical thinking skills on mechanical wave characteristics.

Graphical Analyzer Test of Misconception of 45o Angle as Optimal Angle in Projectile Motion

Riki Purnama — 2024-09-27

Misconceptions still often occur when learning physics, especially in conducting research that is not consistently detailed in identifying an observation. In parabolic motion material, it is known that 45° is a special angle that produces the farthest distance. The misconception that 45° is the angle that produces the farthest distance has become a reference in learning in various educational institutions to date. The aim of this research is to identify and prove that the 45° angle is not an elevation angle that produces the farthest distance in a vacuum that ignores the initial position of the thrower. This research was conducted using PhET virtual laboratory media which was analyzed based on quantitative and qualitative methods. This study will test the elevation angle of 42° : 45° : 48° based on altitude 0 m : 1 m : 2 m. After the observational data has been obtained and proven by the existing equations, the research results will be analyzed based on the functional analyzer approach by making the equations into function graphs to make it easier for readers to read the existing data. In this study, it was found that the angle of 42° is the producer of the farthest distance and also gets a relatively faster travel time compared to the angle of 45° which we know so far as a special angle that produces the farthest distance in non-vacuum conditions.
