This study aims to analyze the effect of the double loop problem solving learning model assisted by powerpoint media on critical thinking skills of elementary school students and to analyze the effect of the double loop problem solving learning model assisted by powerpoint media on learning outcomes of elementary school students. This research is an experimental research with a pretest posttest control group design. The subjects of this study were fourth grade students of SD Muhammadiyah 16 Surabaya. Data collection techniques through student activity observation sheets and student analysis skills tests. The analysis technique used is the t test. In this case the t test is carried out twice, firstly, to determine the initial conditions of the experimental group and control group and second to determine the conditions after being given treatment. The results showed that: first, based on the t test analysis of critical thinking skills, the value of t count> t table (7.439> 1.676) and the results of sig. 2 tailed valued at 0.000 <0.05 with df = 50. Second, the t test analysis of learning outcomes shows the value of tcount> ttable (6.472> 1.676) and the results of sig. 2 tailed valued at 0.002 <0.05 with df=50.Thus, it can be stated that there is influence double loop problem solving learning model assisted by powerpoint media on critical thinking skills and social studies learning outcomes of elementary school students
