PENERAPAN MODEL PBL MELALUI MEDIA LIGHTBOX UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS PADA MATERI SIFAT CAHAYA KELAS IV

Abstract

The abilities that teachers must have are the ability to think critically, have noble character, and use technology wisely. One of them is using teaching aids or media when learning in class. The purpose of this study is to apply simple concrete light box learning media assisted by problem-based learning models that can be useful for improving students' critical thinking skills, especially on the nature of light material in grade 4. In this case the researcher uses a problem-based learning model through light media box to improve critical thinking skills on the nature of light. This research was conducted at SDN Kartini 5 Cirebon City with a total sample of 26 students using the One Group Pre test-Post test Design technique. The approach used is a quantitative descriptive approach with experimental methods. The data collection instruments in this study were questionnaires, test questions and student activity observation sheets. The results of this study based on hypothesis testing show that the correlation test between variables X and Y variables obtained a significance value of 0.000 which means that there is a relationship or relationship between variables X and variable Y. Meanwhile, the Pearson Correlation value between variables X and Y variables is 0.085 indicating that the correlation number is in the strong category, which means that the relationship between the Application of the PBL Learning Model through the Light Box media to Improve Critical Thinking Ability in Material Properties of Light can be said to be successful in its application in class IV SDN Kartini 5, Cirebon City.
