This study aims to produce a Computational Thinking-based Science e-module to improve students'logical thinking skills. This development research uses the ADDIE development model, including Analysis, Design, Development, Implementation, and Evaluation. Data collection uses e-module validation instruments, teacher and student response questionnaires, and logical thinking ability tests. The results of the study show that the IPA e-module based on computational thinking is valid, because the e-module validation results meet the valid requirements. Thinking computation-based science e-modules are practical because the teacher and student response questionnaires are in the very practical category. In addition, the logical thinking ability test instrument is effective because: (1) students' logical thinking skills in limited trials and large-scale trials usually increase, while the n-gain values in limited trials and large-scale trials are respectively 0, 73 and 0.77 with the high category. Thus the thinking computation-based science e-module which is developed is feasible to improve logical thinking skills in science learning.
