Application of The PjBL-STEM Model to Natural Science Learning Devices to Increase The Creativity of Junior High School Students in Environmental Pollution Material
Abstract
The study aims to determinate the project based learning (PjBL) model with the STEM approach in increasing the creativity of junior high school students. The research method used is a quasi-experimental. The design in this study is a one group pretest-posttest design. The population of this research is class VII in a state junior high school in Surakarta. The sample of this study was 44 students consisting of two classes, namely class VII G as the experimental class (22 students) and class VII H as the control class (22 students). The instrument used was a creativity test instrument consisting of 6 questions on the is the N-gain test. Based on the result of data analysis, it was obtained that the experimental class N-gain average was 0.59 with the medium category and 0.36 for the control class with the low category. The result of the t-test show that there is a difference in creativity between the experimental class using the PjBL model of science learning tools with the STEM approach and the class without using the device.
