The Future of Education

Input enhancement refers to a deliberate attempt to make scientific features of second language (L2) input more salient in order to draw learners’ attention to these features. Input enhancement is based on the position that  comprehensible input plays a critical role in L2 acquisition and the input that learners attend to or notice will be acquired. Input enhancement strategies rely on the provision of meaning-bearing input which are composed by the desirable amount of the target linguistic forms. The writer of this paper reviewed the importance and contributions of input enhancement to L2 acquisition, targeted at English, Germany and French foreign language/second language (FL/L2) learners, employed a pretest-posttest-delayed posttest design to investigate the effects of input enhancement on L2 vocabulary acquisition, grammatical structure acquisition and reading comprehension. The findings of the study verified the facilitated role of input enhancement in second/foreign acquisition and furthermore provided implications for language teaching.
