Abstract


Understanding concepts is very important for students to remember information and is closely related to students' attitudes towards things such as the environment. From the results of interviews and reviewing the list of grades of grade X students at Senior High School of 2  Magelang, it can be seen that students' understanding of concepts on ecosystem material and students' environmental care attitudes have not been maximized. This study aims to analyze the effect of using the Project Based Learning (PjBL) learning model on the understanding of concepts in ecosystem material and students' environmental care attitudes. The research method used is a quasi-experiment with a nonquivalent pretest-posttest control group design. The results of the analysis of pretest and post-test values in the experimental class and control class using the ANCOVA test obtained a significance value of 0.046. The results of the analysis of environmental care attitude questionnaires at the beginning and end of learning using the ANCOVA test obtained a significance value of 0.000 in the experimental class. Based on these results, it can be concluded that there is an influence of the PjBL learning model on students' understanding of concepts on ecosystem material and students' environmental care attitudes.
