Science Process Skills through PjBL-STEM on Global Warming Concept

Abstract

This study aims to determine the improvement of students' science process skills in STEM-integrated Project Based Learning (PjBL-STEM) learning on global warming material. The research method used pre-experimental with a population of grade XI MIPA SMAN 1 Rengasdengklok and a sample of grade XI MIPA 6 with 32 students. The instruments used in this study were student activity sheets based on Assessment based on Trajectory Learning (AABTLT) and a test of science process skills descriptions. The data analysis technique used is N-gain and t test. The results showed an increase in science process skills in the experimental grade 0.49 in the medium category, so it can be concluded that there was an increase in students' science process skills.
