Implementation of STEM learning using the slingshot toy project on elasticity and Hooke's law

摘要

Physics learning is now more often using teacher-centered learning even though effective learning should use student-centered learning. Then, it needs improvement; one that can be used is to adopt a learning approach. The learning approach that is considered effective to use is the STEM approach. The STEM approach is a learning approach that integrates four branches of science at once, namely science, technology, engineering, and mathematics. The purpose of this study was to determine whether students' understanding of concepts in learning STEM (Science, Technology, Engineering, and Math) by using slingshot projects on the material elasticity and Hooke law, taking the subject by purposive sampling in the experimental class and the control class. This type of research was a non-equivalent pretest-posttest control group design experimental study with a quasi-experimental design research design, using data collected in the form of tests consisting of pre-test and post-test. The data were processed using statistical tests with normality tests, homogeneity tests, and hypothesis tests. The results obtained from this study are the average value of the experimental class of 72,09 and the average value of the control class of 68,11. The average value of the experimental class is higher than the control class so that the concept of understanding in the material elasticity and Hooke law is better to use STEM (Science, Technology, Engineering and Math) using a slingshot project.
