Input Enhancement in Instructed SLA

The concept of input to the language learner is examined with reference to some current theorizing about language processing and the idea of modular systems of knowledge. The question of what this can tell us about the actions taken by teachers and textbook writers is addressed specifically with regard to manipulating, or “enhancing,” the input ideally so that it will affect learner knowledge and thereby learner behavior. The logic of the argumentation is that, in exposing the learner to the second language, we are engaging a whole battery of different processing mechanisms. Input enhancement research and the conclusions drawn from it have to be set within the context of a modular view of language and language learning.
