Based on the results of observations in SDN Klantingsari I Tarik-Sidoarjo especially in class IV, visible outcomes of student learning in social science is still low and has not reached the minimum completeness criteria. This is because teachers are still applying the conventional learning. Teachers also frequently use the lecture method in implementing the learning process so that students feel bored and not interested in participating in learning. Teachers appear to dominate the lesson so that students are more often used as an object of study than the subject of study. According with this premise, we need a solution.
