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.
Keywords: Interactive Module, Trait Treatment Interaction (TTI), Critical thinking, Kinetic Theory
