Innovation and development of language teaching materials that are appropriate to the development of science and technology need to be done. At present, the development of knowledge and technology has an impact on changing generations. The use of technological devices, such as digital media, mobile applications, websites, etc., has resulted in a change in needs that allows all activities to move faster, one of which is information and knowledge. That has a big impact on education. One teaching material that can be developed is a learning module. At this time, the learning module developed can be done using a variety of digital devices, one of which is mobile. By using a mobile device, practical learning modules are used and can be equipped with various media. The module developed is a learning module writing factual text on the basis of Discovery Learning. This research is R & D (research & development) using a 4-D model (define, design, develop, and dessiminate). Based on the results of validation and trials it was concluded that the learning module is valid, practical, and effective in learning Indonesian.
