of Krashen s Input Hypothesis Three Major Arguments
Second language acquisition (SLA) theories can be grouped into linguistic, psychological and sociocultural theories. Krashen's Monitor Model is seen as an innatist theory within the linguistic group. This paper critically reviews the Input Hypothesis, one of the five hypotheses of Krashen's Monitor Model. It examines three major arguments over the hypothesis, namely, the vagueness of the construct, the simplification of input, and the overclaims that he has made about the hypothesis.
