Chapter#2

Krashen’s input hypothesis is that humans acquire language in only one way. If the input is 1 step (+1) above the stage the learner is at (i). For acquisition to take place, learner must understand messages and receive comprehensible input. There are supportive arguments for input hypothesis which are silent period, age differences, effect of exposure, language learners who do not have access to comprehensible input are held up in language development, success of bilingual programs is due to comprehensible input, reading hypothesis and writing. Three key arguments for input hypothesis are: 1) rule of simple codes, effects of instruction, and methods comparison research. I believe there is ‘acquisition’ without ‘learning’ which means that some people process second language without know rules consciously; there are cases where ‘learning’ never becomes ‘acquisition’ which means that some people know the rules but cannot follow it; and no one knows anywhere near all the rules.
