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.

Abstract

This research is driven by the students’ scientific literacy has not been well facilitated because the teaching materials used have not optimally supported its development. The purpose of this study is to develop and analyze the validity of the problem-based learning physics module intended to facilitate students’ scientific literacy. This study employed a research and development (R&D) method to develop and validate the module. The validation process was carried out by three physics lectures from the State University of Padang (UNP) and two high school physics teachers. Expert validation was carried out to assess six component: content feasibility, presentation, graphics, language, problem-based learning steps, and scientific literacy. Based on the data analysis, the developed module obtained a Aiken’s V index of 0.89, which falls into the valid category. Therefore, it can be concluded that the problem-based learning physics module developed to facilitate high school students’ scientific literacy is valid and appropriate for use as an innovative teaching material that effectively supports the physics learning process, particularly on the topic of climate change.
