This paper studies the effect of scaffolding approach assisted by PhET simulation on the achievement of science process skills in physics. This paper used pre-experimental design with a one-shot case study. The sample of this study was students of class XI MIPA MAN 1 Yogyakarta. The sample consisted of 2 classes with the total of 57 students from the whole 3 classes selected by purposive sampling technique. The scaffolding approach in this paper consists of three levels, those are environmental provision, reviewing and restructuring, and developing conceptual thinking. The data was collected through observation of science process skills by using a checklist sheet. Aspects of science process skills which was observed included observing, formulating hypotheses, conducting experiments, interpreting, concluding, and communicating. The data analysis used descriptive analysis, calculation of the percentage of achievement of each aspect of science process skills, and calculation of the percentage of categories of achievement of science process skills. The results of the study show that the scaffolding approach assisted by the PhET simulation has a very good effect in physics learning for the achievement of the science process skills in physics. © 2019 Published under licence by IOP Publishing Ltd.
