This collection of 10 essays on the nature of second language learning focuses mainly on distinctions between the audiolingual and the cognitive-code theory of learning and also on the interrelationships between psychology, linguistics, and second language learning. A synthesis which cuts across divisions in methodology, caused by superficial stereotyping of the various teaching methodologies, is attempted. Specifically, suggestions are made which facilitate an application of transformational theory, based on Noam Chomsky's writings, to the development of a functional methodology of language instruction.
