All theories and studies regarding second language acquisition go back to the nature of input and how when an L2 learner uses the input in interactions the learner will produce language and forms (output) directed by the feedback. Krashen believes that the input hypothesis is the answer to how the natural order hypothesis takes place and how an L2 learner moves from one stage to the next in SLA. (Gass, 1997). One of the key issues of SLA is the role of the input hypothesis and the role it plays in the L2 process. Furthermore L2 acquisition can only happen with enough L2 input. When input is in the right amount and well practiced the formation of language is produced which therefore is the transformation of the learned input …show more content…
The Input hypothesis is Krashen 's attempt to explain how the learner acquires a second language. The Input hypothesis is only concerned with 'acquisition ', not ‘learning’. The input hypothesis also suggest that the learner must be aware of the need to learn the second language. Krashan suggest’s that all human’s acquire a language the same way, through this Krashan discusses his input hypothesis which states that language is acquired only when the L2 learner is exposed to a step beyond his language level (i+1). Although i must suggest that the i+1 will only be successful if the communication succeeds (Ellis,1985). This suggests that the L2 learner will only acquire knowledge when exposed by new material that builds off of the learners prior knowledge. This therefore helps the learner develop and progress their language. Some of the key aspects of the input hypothesis is that to acquire a language the L2 learners must be exposed to a level above their competence where the L2 learner will use the context and the use of their linguistic competence to identify the new language. The idea of comprehensible input is that the the L2 learner is exposed to gestures and context with the association of the input to direct the learner to the correct meaning. For L2 learners to fully comprehend the new language the L2 learner will need to be exposed to paraverbal adaptations which will extend the meaning through gestures, facial expressions and vocalisation of the new
