Based on the Natural Approach, Dos mundos: En breve stresses the use of engaging activities and interesting readings in a natural and spontaneous classroom atmosphere. In this comprehension-based approach to learning language, the development of communicative language skills is the central goal, with formal grammar presentation and grammar practice at the service of communication. The text is designed so that class time can be devoted to exposing students to Spanish through creative activities and readings, allowing grammar explanations and exercises to be studied outside the classroom.
