<![CDATA[ABSTRACT This research activity was used to determine the learning outcomes of students of SD Negeri Mojoagung - Soko - Tuban in science subjects, material Chapter 7: How to Get All Our Needs? by applying the Project Based Learning (PjBL) model. This type of research is Collaborative Classroom Action Research (PTK). The purpose of the study is to improve student learning outcomes through learning activities using the Project Based Learning model (PjBL). The data collection instruments used are using observation instruments, questionnaire/ questionnaire sheets, written tests and documentation. Data analysis techniques use quantitative and quantitative data analysis techniques. Before carrying out the action, researchers carry out a pre-cycle which is used as a comparison of research success. Each cycle consists of one meeting consisting of the stages of action planning, action implementation, observation or observation and reflection. The results obtained in the application of the Project-Based Learning (PjBL) learning model in grade 4 at SDN Mojoagung obtained pre-cycle results of only 16% complete learning then carried out cycle 1 obtained an increase in results to 67%. After making improvements to the teaching module and improvements related to the surrounding environmental conditions, student learning outcomes were able to increase by 83% in the cycle. So it can be concluded that this research runs according to expectations and the learning outcomes of students are able to improve. Keywords: Learning result, PjBL, 4 class.
