Abstract

The knowledge of the student about harmonic oscillators is quite limited. The purpose of this PPM is to 1) increase the knowledge of Bengkulu City 5 SMAN students about Quantum Harmonic Oscillators and their application in everyday life 2) improve the skills of Bengkulu City 5 High School students in calculating Quantum Harmonic Oscillators using the fast-forward method to accelerate quantum dynamics adiabatic. PPM was carried out at SMAN 5 Bengkulu City, especially in class 12 IPA 5 on October 24, 2022. The research method was carried out in three stages. The first stage is preparation. The second stage is the presentation of quantum harmonic oscillator material using research instruments in the form of power points, the third stage is research evaluation.

Abstract

This study aims to determine the characteristics and feasibility of the e-module developed using flip pdf corporate edition to improve the critical thinking skills of high school students. This research is a follow-up research that has been done previously which is only limited to the analysis stage, the method in this research is R n D with the ADDIE model which has five stages, namely; analysis (analysis); design (design), development (development and testing); implementation (use); and evaluation (evaluation), but in this study it was only carried out until the develop stage. The assessment instrument used in this study was an expert validation sheet containing material aspects, language aspects and media aspects. Based on the results of product validation tests by experts, the percentage score of 88% for the material aspect, 92% for the language aspect, 89.58% for the media aspect, and 85% for the critical thinking aspect so that the total average score is 88.6% including the in the very valid category. And the result of student perception response showed very good with a percentage of 87.64 % . Thus, the e-module material on elasticity and Hooke's law uses a flip pdf corporate edition to improve the critical thinking skills of high school students into a product that is feasible to use.

Abstract

Background: The rapid development of digital technology in education requires innovative laboratory equipment that supports interactive and accurate learning processes. Teaching physics on the topic of specific heat substances still faces challenges, including limited laboratory equipment, low accuracy and precision, and difficulties with analog calorimeters.Aims: This study aims to develop a digital calorimeter based on game-based learning and to analyze its feasibility and effectiveness in improving students’ learning interest and conceptual understanding.Methods: The ADDIE model was used in this study's research and development methodology. Students from SMA Negeri 11 Bengkulu City's Class XI C served as the research subjects. Data were collected through expert validation, sensor performance testing, concept comprehension tests, and a learning interest questionnaire.Result: The research results show that the load cell sensor has a precision error of 0.14% and an accuracy of 0.01%, while the NTC sensor has a precision error and accuracy of 0.19%, thus meeting the experimental measurement requirements. Expert validation yielded a feasibility score of 92.13%, classified as “highly feasible.” The implementation of the learning program demonstrated increases in conceptual understanding (N-Gain of 0.92, high category) and in interest in learning (N-Gain of 0.71, high category).Conclusion: Digital calorimeters are highly suitable for supporting more effective, contextual, and participatory physics learning, and they contribute to the creation of lab resources based on digital technologies that improve the quality of learning and students' active engagement in experimental activities.
