The stages of this research method include (1) analysis of the need for teaching materials according to teachers and students; (2) development of initial products; (3) validation by expert and revision; (4) small-scale field trials using the experimental research method with the design of Paired T Test, Normality test, and homogeneity test. To determine the module's suitability, the results of the five-scale questionnaire is interpreted. The results show that; (1) the idea of the need for teaching materials according to the teacher and students receives a good response; (2) assessment (expert response) regarding the content of the material gets a score of 39.00 with a very good category from expert validator, and a score of 33.00 with a good category from the Indonesian language teacher.

Furthermore, it is also known that the post-test data shows a learning completeness of 100%, and the average score of the data is 89.8 with the percentage of learning completeness of 80%. In other words, there is an average increase of 30.7;(4) the module is proven to be effective after being tested in the experimental class and the control class as the t value of the experimental class is greater than the t value of the control class (19.030> 18.573). The experimental class has more improvement than the control one. Therefore, it can be concluded that learning with the module is more effective than the conventional learning.
