Pengaruh Penerapan Model Pembelajaran Inkuiri Terbimbing dengan Praktikum Konversi Energi Panas Ke Lisrik untuk Meningkatkan Kemampuan Berpikir Kritis

Abstract

This study aims to determine the effect of the application of guided inquiry learning models with the practice of converting heat to electricity to improve critical thinking skills. The population of this research is all students of class XII Science of SMA Negeri 1 Way Jepara. The selection of research samples using purposive sampling techniques with a sample of class XII Science 5 totaling 33 students. The research design used was One Group Pretest-Posttest. Learning is done by conducting practicum activities using a set of guided inquiry-based heat energy conversion devices. The tool used in practicum activities is an advantage in this study because there has been no previous research that uses practicum learning methods with tools to convert heat energy to electricity. Practicum activities carried out on two learning topics or practicum twice. In practicum activities topic one is about the unit thermoelectric generator module specifications and in practicum activity topic two is regarding the thermoelectric generator circuit to turn on the LED lights. Data were tested by N-gain analysis, normality test, Paired Sample T-Test. Based on the results of the Paired Sample T-test, it can be seen that the significance value of 0.00 is less than 0.05, it can be concluded that there is an influence of students' critical thinking skills before and after using guided inquiry learning models with energy conversion practicum.
