Abstract

This research aims to analyze students' interest in learning science. The method used is a survey. Data collection techniques used interest questionnaires and interviews. The research was conducted on 409 junior high school students in Bandung, Indonesia, consisting of 201 male students and 208 female students. The research results show that students' interest in learning science is in the good enough level interest category. This research also identified factors that can influence students' interest in learning science in sequence. Five factors include teacher, family, informal learning experiences, learning experiences in the classroom, and friends. Analysis of students' interests based on gender was carried out using the Kruskall-Wallis Test. There is a difference in the average score of students between men and women, which shows that female student's interest in learning is higher. Based on student's responses to open questions and interviews, information was obtained that the reason they were interested in science was that science was material that had many practicum concepts that could be carried out, exciting learning activities, and support from parents at home. Meanwhile, the most dominant reasons they are not interested in science are the physics material, which contains a lot of calculations and the science teachers are not interesting.

Abstract

This research was conducted to obtain an initial design for a laboratory practical tool based on bifocal modeling assisted by an ESP32 microcontroller for kinetic gas theory. This study was conducted to obtain an initial design for a practical laboratory tool based on bifocal modeling assisted by the ESP32 microcontroller on the kinetic theory of gases. This study was conducted descriptively through a literature review of various book articles and materials. Interviews were conducted with students and physics teachers in high schools (9 students and two teachers in Malang, 15 students and three teachers in Bandung) in Indonesia. Interviews were conducted to obtain an overview of the application of physics learning and reveal other potential problems students and teachers face. The design of the bifocal modeling tool developed has been consulted with physics and ICT learning experts. The results are that it needs to be further developed and maintained until the manufacturing stage. Bifocal modeling based on the design developed in this study has the potential to facilitate students to conduct scientific experiments related to the kinetic theory of gases. Based on the equipment to be developed, it is expected that students will be able to observe macroscopic gas phenomena through actual experiments, monitor microscopic phenomena visualized through computer models, collect data in actual experiments and computer simulations, and compare data. Students' understanding of the concept of the kinetic theory of gases has the potential to be improved by conducting practical work using bifocal modeling-based tools.
