In other words, students subject to this kind of teaching know a lot about the language. However, these students are unable to use the language itself appropriately in contextualized situations for different reasons. In this respect, language learning, according to the different works in the field related to materials development for language learning, recommends that course books should provide learners with more opportunities to acquire language features from frequent encounters with them during motivated exposure to language in use. Different authors support this position from a variety of angles: Experiential learning theory claims that learners gain most from apprehending from experience before comprehending from analysis.Comprehensible input theory states that acquisition is facilitated by meaningful and motivated exposure to language in use. Deep processing theory also claims that meaningful encounters are necessary to achieve the deep processing needed for durable learning. There is also support for this position from Asian applied linguists who argue for a reduction in the number of textbook activities involving explicit teaching of language and an increase in opportunities for implicit learning. Yet, for reasons of the present paper, I think that the most effective way of acquiring language implicitly from motivated exposure is through opportunities to reflect on language as a structural input in different academic tasks
like writing, reading or article reviews.
