Abstract

This research explores the development and innovative implementation of an Arduino Uno-based Geiger-Muller counter (GMC) as a physics learning tool designed to enhance students’ critical thinking skills. The aim was to address the gap in effective educational media in teaching radioactivity materials. This research used the analysis, design, development, implementation, and evaluation (ADDIE) model, which includes the analysis, design, implementation development, and evaluation stages. The sample of this study involved 165 students at University of PGRI Pontianak, using a pre-experimental design with one pretest-posttest group. Validation by experts and feedback from students confirmed the high validity and effectiveness of the media, with significant improvements seen in critical thinking indicators such as evaluation, analysis, interpretation, and inference. The use of real-world materials, including red Borneo agate testing, provided a practical context that enriched the learning experience. Although there was no control group, the findings suggest that integrating hands-on technology-based tools into physics education can significantly improve students’ critical thinking skills. This study contributes to the growing literature on educational innovation, offering practical solutions to improve critical thinking in science education through interactive and contextually relevant learning media.

Abstract

The purpose of this community service activity is to provide skills to physics teachers at the Pontianak City Physics MGMP to develop practical-based learning and STEM Phase F applications. The method of implementing PKM is training and mentoring. The stages of implementing PKM consist of stage 1) preparation; stage 2) socialization which includes activities of resource person presentation, discussion, and question and answer; and stage 3) implementation and mentoring, which includes activities; and 4) monitoring and evaluation. This activity succeeded in increasing teachers' insight and skills about the implementation of STEM Phase F in practical-based learning activities. In addition, teachers' skills in compiling STEM-based learning devices also increased. This program succeeded in introducing the application of STEM in practical-based Physics learning in the Lab. The positive response of participants showed motivation to apply STEM and partnerships between universities and schools as the first step to creating an innovative and sustainable learning environment. This PKM produced outputs, namely news in the online mass media of the KALBAR Regional Government
