  • This study aims to develop the trigonometric module using Treffinger model for the tenth grade of vocational school. The module was tested on 10 students of tenth grade in BKP Vocational School. By developing the module using Treffinger model, it will help students to study independently. This study using ADDIE (analysis, design, development, implementation, evaluation) development model. The module that has been developed contains trigonometric materials which use Treffinger model stage, exercises, sample questions, and evaluation. The first step taken was to analyze the needs, standard content, and teaching materials. Then make the module design. In the next step, the module is validated by media and material experts. The data collection needs used are student response questionnaire to measure the module practicality and asked the students to work on evaluation questions to measure module effectiveness. The study result shows that the module is included in the good category, student response questionnaire data also shows good category, and the evaluation result shows that students got the score above the minimum criteria of mastery learning (KKM). The module has met the valid, practical, and effective categories.
