AbstractThe development of the learning module reduction reactions of oxidation with Constructivism approach is based on the low student learning results and the limited number of teaching materials that in accordance with the characteristics of student learning. The purpose of the development of this learning module is to produce learning media that can be used independently. Development model used in this research using the model of the 4-D include: Define, Design, Develop, and Disseminate. The research results show that the design of the development of the learning module in this research consists of (1) Analysis of electrostatic curriculum and materials (2) analysis of the characteristics of students (3) Analysis of student learning tasks. Module development phase begins with do the arrangement of the material/writing module, then module review by the experts to show the module meets the feasibility criteria with an average of 3.77 values and field trials that shows a positive response to the use of module 83.2%. The module profile that is produced after the development phase meets the criteria of Self Instruction, Self Contained, Stand Alone, Adaptive and User Friendly. Students learning gains after the use of the learning module shows that the students can be actively using the module in the learning activities and the level of students understanding of the concept of oxidation reduction reactions good enough this can be seen from the average value of the students is 77.98 ≥75 (KKM).Key words:        Learning module oxidation reduction reactions, Constructivism approach
