Abstract
This study aims to develop a Higher Order Thinking Skill (HOTS) chemistry module which is integrated with the Problem Based Learning (PBL) learning model on the colligative properties of solutions in general chemistry courses. This research was conducted at the Department of Chemistry, Faculty of Mathematics and Natural Sciences, Medan State University. The development of this chemistry module is carried out using a 4-D development model. Then validated by expert validators and see how students respond to the chemistry module. Based on the data analysis of the feasibility test carried out using the kappa-cohen test, the kappa moment value of 0.769 was included in the ^high^ category with a feasibility percentage of 83.3%. This is also supported by data on student responses to the chemistry module which received a positive response with an average percentage of 91.10% which was included in the very good category.
Keywords: Chemistry Module, Higher Order Thinking Skill, Problem Based Learning, colligative properties of solutions
