<![CDATA[The background of this research is the learning outcomes and learning activities of fourth grade students of SDN 2 Mantingan in social studies subjects are low so it requires improvements to improve learning outcomes and active learning of fourth grade students of SDN 2 Mantingan in social studies subjects. The purpose of this study was to find out the improvement of learning outcomes and active learning of fourth grade students of SDN 2 Mantingan in social studies subjects using a problem based learning model. The type of research used is classroom action research. This research was conducted at SDN 2 Mantingan with a total of 32 research subjects. Data collection techniques used are tests and observations. The validity of the data used is expert judgment. The results showed that the use of problem based learning models could improve learning outcomes and active learning of fourth grade students at SDN 2 Mantingan in social studies subjects. In the pre-cycle the average value obtained by students was 62.84 with a classical completeness of 31.25%. Then in the first cycle the average value obtained by students is 74.21 with classical completeness 32.14%. From the pre-cycle to the first cycle there was an increase in the average value of student learning outcomes which was 11.37 and an increase in classical completeness 0.89%. In the second cycle, the average score obtained by the students was 75.34 with a classical completeness of 84.61%. From cycle I to cycle II there was an increase in the average score of 1.13 and an increase in classical completeness as much as 52.47%. The average value of student activity in the pre-cycle is 46.15% and is included in the criteria for being very less active. In the first cycle, the average value of student learning activity was 71.78% and was included in the criteria for being quite active. From the pre-cycle to the first cycle, there was an increase in learning outcomes as much as 25.63%. In cycle II, the average value of student learning activity is 86.92% and is included in the very active criteria. From cycle I to cycle II there was an increase of 15.14%.
