Improvement ff Project-Based Learning Models Through Collaborative Skills of Grade IV Students on Plant Topics and the Environment at SDN 1 Cilayang

Abstract

Natural Science (IPA) education in elementary schools plays an important role in developing students' critical, creative, and analytical thinking. This research aims to improve the learning outcomes of science students in grade IV of SDN 1 Cilayang through a project-based learning model with an emphasis on collaborative skills, especially plant and environmental topics. The main problem is monotonous learning and low student collaboration skills, leading to suboptimal understanding of scientific concepts. Using the Classroom Action Research (PTK) method with two cycles, involving 23 students as a sample from a population of 48 students. Data were collected through observation, tests, and non-test instruments, analyzed in a quantitative descriptive manner. The results showed a significant increase: pre-cycle completeness of 47.83% (11 students reached KKM 75), cycle I increased to 60.87% (14 students), and cycle II reached 91.30% (20 students). The model effectively develops 21st-century skills such as collaboration, communication, and environmental awareness, as well as addressing gaps in the implementation of project-based learning in rural elementary schools. The implications support an independent curriculum and improve the quality of science education.
