This study has an objective to specify the feasibility of a Structured Assignment Sheet to train studentsââ¬â¢ Science Process Skills (SAS-SPS) on reaction rates material. The development research applies Research and Development (R&D) method. This research is limited to the development phase, namely in limited trials. The limited trial was conducted on 15 students of XI grade from SMAN 1 Arosbaya, SMAN 1 Kamal, and SMAN 2 Bangkalan who had received reaction rates material. This research was held in December 2020. The research instruments used contain a study sheet, a validation sheet, a student response questionnaire, and science process skills test sheet. The feasibility of the SAS-SPS is viewed from three aspects, namely validity, practicality, and effectiveness. The validatorââ¬â¢s assessment based on the content and construct validity represent the percentage of 93,3% and 91,4% with very valid criteria. Student response shows that the SAS-SPS is very practical with a percentage of 100%. The effectiveness of obtaining an N-gain score of 0,76 with a high category. This shows that the SAS-SPS developed is feasible and suitable for use in the learning process.
