Developing physics learning tools based on the local community traditionabout global warming to improve student’s understanding

Learning physics will be more meaningful if it is associated with local habits found in an area. This study aims to develop a physics learning device based on the local community’s traditions and the effect of its application on learning outcomes in SMA Negeri 1 SoE students. The method used is Research and Development (R&D). The results showed that the results of the validation of the physics learning tool based on the habits of the local community by the experts as a whole met the appropriate criteria. The calculation of the evaluation questions showed that the validity of the questions was in the very high and high categories, the reliability value of the questions was rcount (0.92 and 0.94)>r_table (0.632), also the discriminatory power and level of difficulty of the questions were good. Therefore, they could be used as test tools. Physics learning tools based on local people’s traditions on global warming material effectively increase students’ conceptual understanding with an N-Gain of 0.78 (high). In conclusion, physics learning based on local people’s traditions is valid, feasible, and practical to use in the learning process.
