This full research paper is concerned with structuring educational content for mobile learning. Mobile devices are present in various areas of society and, in the educational context, the available resources of mobility and connectivity have contributed to their growing adoption. However, the generation of educational content for mobile devices requires special attention to issues such as: (i) restrictions on mobile devices; and (ii) complexity of developing mobile applications, related to the variety of existing platforms. This paper presents Educom.ml, which is a modeling approach for mobile educational content supported by MDE (Model-Driven Engineering) and IMA-CID (Integrated Modeling Approach - Conceptual, Instructional, Di-dactic). Educom.ml proposes a modeling approach that involves creating models that structure educational content and models that model mobile platforms. In this context, MDE minimizes the complexity of developing cross-platform applications and the automatic generation of educational content. Meanwhile, IMA-CID is responsible for structuring and organizing educational content. To illustrate our ideas, a mobile app was generated based on modeling educational content in the field of elementary mathematics.
