<![CDATA[This research aims to find out the level and improvement of science process skills before and after the application of structured inquiry learning model assisted by PhET Simulation. This research is a pre-experiment research using one-group pretest-posttest design. The population all grade IX SMP Negeri 2 Sendana with a total of 53 students. Sampling through saturated sampling technique the sample in this study was class IX students totaling 53 students. The research instrument was a multiple choice science process skills test totaling 20 validated items. The data collection technique is the pretest and posttest. Results of descriptive analysis the average value science process skills of students at SMP Negeri 2 Sendana before and after application of structured inquiry learning model assisted by PhET simulation on dynamic electricity, the average pretest value of 41.88 the low category and posttest value of 67.45 the medium category of the maximum value of 100 and the average N-Gain of 0.44 the medium category. The results of inferential analysis with t-test obtained tcount = 29.76 > ttable = 1.67, concluded that there is an increase in science process skills after the application.]]>
