One of the greatest impacts of corpus linguistics on language teaching has been in the recognition of the importance of collocation. A very influential guide for language teachers with regard to teaching collocation has been the Lexical Approach. Activities pointing students to rich collocational information in monolingual dictionaries, in texts and specifically in collocation dictionaries provided ways for language learners to engage with collocation information: to notice, to remember and to acquire. In recent years, there has been a growing interest in Data Driven Learning and new tools are now available to allow students to access collocation information from corpora for themselves. After introducing some pedagogic considerations, this article presents some of the features of The Prime Machine which were developed to support DDL activities focussed on collocation.
