Abstract

Learners in the 21st century must have 4C skills, among these is the capacity for critical thought, especially in physics learning. Students' critical thinking abilities must be examined in order to prepare them for the twenty-first century. Assessment instruments that specifically assess students' critical thinking skills on momentum and impulse material are not yet available. So this research aims to develop a valid electronic assessment to assess students' critical thinking skills on momentum and impulse material. This research is development research (R&D) using the Plomp model. The data collection instruments used were interview sheets, self-evaluation sheets and validation sheets. The developed electronic assessment was validated by three validators. The electronic assessment had a high validity category in terms of material substance, learning design, visual communication, and software use, according to the validity analysis results. From the validation results with an average value of 0.92, it shows that the electronic assessment to assess students' critical thinking skills on momentum and impulse material is declared valid and feasible to use.

Abstract

Understanding concepts is important in learning physics because it helps students connect theories with real-life phenomena, develop scientific reasoning, and avoid misconceptions. However, in practice, physics learning still faces challenges, especially in the topic of straight-line motion. One solution is an educational physics game based on cognitive conflict, which is expected to improve students' concept understanding and correct misconceptions. This research is a type of development research using the Plomp development model. The educational game developed is based on cognitive conflict and consists of four stages: 1) Activating prior knowledge and misconceptions, 2) Presenting cognitive conflict, 3) Discovering concepts and equations, and 4) Reflection. The validity results for the physics educational game are V = 90, which is in the very valid category, and the practicality results are 92.48, which is in the very practical category. Based on these results, it can be concluded that the physics educational game based on cognitive conflict for improving students' concept understanding in the topic of straight-line motion meets good validity criteria and can be used in the learning process as an interactive teaching material.
