The ability to communicate orally in a foreign language is fundamental and highly evaluated by both students and teachers. Therefore it is important that educational materials can provide communicative activities that improve this ability. A study of educational materials for young French learners revealed that the activities aimed to practice oral communication in fact were not really communicative. This investigation analyzes three educational materials for beginners in Spanish. The purpose is to see which kinds of activities the materials can offer for practice of oral and interactive communication, to compare them with educational theories and the Swedish curriculum and to detect similarities with the former study. The results show that the majority of the activities used in the materials, are not really communicative, they are mostly based on prepared phrases and there are few possibilities for creativity.
