This research aims to describe the implementation of guided inquiry learning using STEM approach and describe the improvement in student science process skills (SPS). This type of research is pre-experimental with one group pre test-post test design using 1 implementation class and 2 replication classes. The technique of analyzing learning implementation data uses the learning implementation sheet assessed by the observer. While the improvement of SPS using pre-test and post-test sheets were analyzed using paired sample T-test, n-gain, and ANOVA. The results showed that the implementation of learning obtained a value of 3.47 or 86.75% and in the excellent category. There is a significant difference between the value of the pre-test and post-test. The improvement of SPS in the three classes obtained a value of <g> sequentially in the amount of 0.55, 0.63, 0.62 and the medium category but the increase in the value of SPS in these three classes was inconsistent. Based on this research it can be concluded that the implementation guided inquiry learning using STEM approach can improve student science process skills. © 2019, Beijing Science Education Innovation center.
