The use of modules in learning aims so that students can learn independently without or with guidance from educators, so that students will learn better if they are done alone which focuses directly on mastering learning objectives. The reality found in the field is that technology-based teaching materials are not used optimally and educators are seen to still give the same treatment to all students without paying attention to differences in the characteristics and needs of students and critical thinking skills in students who have not developed. Efforts to solve every problem in learning physics in line with changes in information and communication technology in the form of using computers during learningamong them are interactive teaching materials. The aim of this research is to produceInteractive module based on Trait Treatment Interaction (TTI) using Adobe Flash on critical thinking skills (Critical Thinking) of students on the material of gas kinetic theory and the laws of thermodynamicsclass XI SMA / MA that is valid, practical and effective. This research is a research and development (R&D). Development design is using a development model ADDIE consists of: the Analysis stage (analyzing), the Design stage (designing), the Development stage (developing), the Implementation stage (implementing) and the Evaluation stage (evaluating). The instruments used in this study were validity questionnaires, practicality questionnaires, and effectiveness tests. The product validity test is given by expert validators in the aspects of material / content, media / construction, and language. The practicality test is given to educators and students, while the effectiveness test is given to students. The results of the research were producedInteractive module based on Trait Treatment Interaction (TTI) using Adobe Flash for students on the material of the kinetic theory of gases and the laws of thermodynamics which is very valid, very practical and very effective on critical thinking skills of students.
