Implementation of Discovery Learning on the Human Excretory System Material to Improve the Activeness and Learning Outcomes of Class VIII Students

This research is motivated by the low level of student engagement and learning outcomes of eighth grade students at MTs Kalimbuah on the Human Excretory System. This problem is thought to be caused by the learning process still using conventional methods, where teachers play a more dominant role in the teaching and learning process and students tend to be passive. Furthermore, the human excretory system material is relatively complex, requiring in-depth understanding. This research used the Classroom Action Research (CAR) method, which was implemented through two cycles. Each cycle began with the planning stage, followed by action, observation, and ended with reflection. The learning model applied was Discovery Learning, which is designed in such a way as to encourage students to be active in discovering concepts through a process of exploration and investigation. The results of this study indicate that the application of Discovery Learning successfully increased student engagement during the learning process. This success was marked by increased student participation in discussions, answering questions, and summarizing the material. The percentage of classical class completion also increased, from 57% in the first cycle to 86% after the second cycle. Based on these results, it can be concluded that the use of the learning model Discovery Learning effective in improving the quality of learning on the human excretory system. Therefore, Discovery Learning can be used as an alternative learning model in learning science material.
