The article provides an analysis of some existing interpretations of the concept of developmental teaching. On the basis of this analysis motivation for communicative competence in reading texts on specialty in foreign language is justified. Mastering communicative competence in reading literature on specialty in foreign language is dictated by such needs as: obtaining information in a particular field of science or technology, in-depth knowledge of reality on the basis of scientific data and communication through written forms of speech.
