Abstract

The purpose of this study was to determine the feasibility and effectiveness of the development of IPA based on Contextual Learning to improve critical thinking skills. The data analysis technique in this study is the N-Gain test. The results of the expert validation test were carried out on 6 experts, namely 2 Indonesian language experts, 2 material experts and 2 learning media experts. the average score obtained by Indonesian language experts is 42.5 with a percentage of 88.54% (very valid), then the average score by material experts is obtained by 56.5 with a percentage of 88.28% (very valid), then obtained the average score by learning media experts with a score of 88 with a percentage of 95.65% (very valid). The results of field trials were carried out on a small, medium, and large scale in this study, namely the total score obtained from 3 students, the average value obtained was 47.18 with a percentage of 83.37% (Very Valid). For the effectiveness test, the interpretation of the effectiveness of 71.58% is in the range of 56 - 75 so it can be concluded that the Science Student Worksheet Based on Contextual Learning is "quite effective" in increasing students' ability to think critically on heat transfer materials.
