Adapted from the Dick and Carey model. The data from the module validation results are obtained as follows: Responses from the validation expert (1) The material quality component on the material suitability criteria has an average score of 3.0 with a good category, on the material shortage criteria has an average score of 3.5 with a good category, while the criteria for learning support materials have an average score of 3.0 with a good category. (2) the linguistic quality component on the criteria for conformity with the level of development of students has an average score of 4.0 with a very good category, on the communicative criteria has an average score of 3.0 with a good category, while the criteria for coherence and integration of the flow of thought has an average score of 3.0 with a good category.
