Overlapping of ESP/EAP and content courses revisited

[ES] This paper deals with some key issues in a controversial topic, that of the existing overlapping between ESP/EAP courses and simultaneously-run content courses. Some examples are provided and analyzed to be aware of the need of ESP/EAP practitioners to have a fairly deep knowledge of those technical matters they have to deal with in order to be as genuinely communicative as possible. Later on, a list of principles for designing successful ESP/EAP courses is presented and justified. After putting into practice a communicative approach founded on those principles for a period of five years, the opinion of those students who have taken two ESP/EAP courses was gathered –an ad hoc questionnaire was developed for the purpose–. data are analyzed to hypothesize the long-run correlation between applying the above mentioned principles and the positive opinion of students on their teachers when those principles are applied at university level.
