There is almost a unanimous agreement among both practitioners and language learners that collocations are among the most challenging aspects of second language vocabulary learning. Because of this, finding more efficient ways of teaching collocations has long been the focus of teachers' and researchers' attention. In modern education, direct explicit teaching practices have lost much of their credibility and appeal. An alternative to explicit teaching could be input enhancement, which may happen in a multitude of ways. This book contains a theoretical review as well as an empirical analysis of the effects of three types of input enhancement (visual and semantic input enhancement and input flooding)on the comprehension and production of lexical collocations. It can be useful for second language learners, teachers, researchers and syllabus designers.
