Abstract
This study was conducted to describe the improvement of student learning outcomes in learning that applied guided inquiry assisted by simulation media on temperature and heat materials. This research was carried out on students in grade VII-G at UPT SMPN 18 Gresik by conducting pre-test activities, three learning treatments, and post-tests. The type of research used is pre-experimental research with a one group pretest posttest research design. The learning outcomes of students were measured by pretest and posttest questions with a sample of 31 students in this study which was measured by N-Gain analysis and to test the significance, the Wilcoxon test was used. The learning outcomes obtained by students have increased with an increase in N-Gain of 0.40 with a "Medium" interpretation. In addition, the results of the significance of the pretest and posttest scores showed a value of 0.000 (<0.05) which means that there was a significant increase in the pretest and posttest results.
