This study aims to create a student learning module that trains computational thinking skills in students of SMP Negeri 1 Air Upas, Ketapang, West Kalimantan in solving problems about angles.

The research model is ADDIE. The study subjects were students of class VII B of SMP Negeri 1 Air Upas. The study began with the analysis stage student needs, and student learning environments. The design stage starts from determining the framework and content regarding the angles. At the development stage, the researcher began to create and develop the framework and content that will be created in the module. At the implementation stage, the researcher conducted a trial in class VII B of SMP Negeri 1 Air Upas.

The module received an overall average from experts of 84.54%, meaning "Valid". From the results of filling out the questionnaire by students, an average of 73% was obtained which means "practical". The overall average level of effectiveness of completing the types of angles and exercise 1 activities was 74%. It can be concluded that the quality of the developed module is valid, practical, and effective for use by students to build computational thinking skills.
