Solving the problem with the use of cooperative learning. Solving the problem with the use of cooperative learning. Applying cooperative learning model, learning model by assigning student groups attract, train and train remedy issue an opinion for the good cooperation. This research aims to improve learning outcomes IPA Elementary School fourth grade students 003 Peranap the academic year 2014/2015. The subject is a fourth grade primary school students 003 Peranap the number of students as many as 20 students. This research is a form of action research with two cycles. The research data show that the learning outcomes of students has increased, the value of acquired activities of teachers in the first cycle with the average was 72.32% and the second cycle increased by an average of 90.18% of students in the first cycle of activity with an average of 69.31% and the second cycle increased by an average of 90.18%. Research data has increased which before the action model of cooperative learning on the base score of complete 3 people tuntasdan 17 people who did not complete the average value of 59.8 the first cycle increased the number of students 20 people, with an average value 71dan cycle II nliai amount to an average of 81 can thus be concluded that the hypothesis in this study is "if implemented model of cooperative learning, it can increase learning outcomes IPA Elementary School fourth grade students 003 Peranap acceptable.
