Abstract: This research has been carried out to produce a Structured Assignment Sheet with Example Applications in Daily (SAS-EAD) on the sub-material factors that affect the reaction rate suitable for use as chemistry learning media for class XI in high school. This research applies the Research and Development (R&D) way to deliver SAS-EAD that complete criteria of validity, practicability, and effectiveness. From January to February 2021, a limited trial was carried out in SMAN 1 Kandangan, who had obtained the factors that affect reaction rate material with a total of 15 people. The instrument used in this study consisted of a validation sheet, a student response questionnaire, and a test sheet.
