Our research explores the search behaviour of EFL learners (n=24) by tracking their interaction with corpus-based materials during focus-on-form activities (Observe, Search the corpus, Rewriting). One set of learners made no use of web services other than the BNC during the central Search the corpus activity while the other set resorted to other web services and/or consultation guidelines. The performance of the second group was higher, the learners’ formulation of corpus queries on the BNC was unsophisticated and the students tended to use the BNC search interface to a great extent in the same way as they used Google or similar services. Our findings suggest that careful consideration should be given to the cognitive aspects concerning the initiation of corpus searches, the role of computer search interfaces, as well as the implementation of corpus-based language learning. Our study offers a taxonomy of learner searches that may be of interest in future research.

Combined with the ubiquity and constant connectivity of mobile devices, and with innovative approaches such as Data-Driven Learning (DDL), Natural Language Processing Technologies (NLPTs) as Open Educational Resources (OERs) could become a powerful tool for language learning as they promote individual and personalized learning. Using a questionnaire that was answered by language teachers (n 230) in Spain and the UK, this research explores the extent to which OER NLPTs are currently known and used in adult foreign language learning. Our results suggest that teachers' familiarity and use of OER NLPTs are very low. Although online dictionaries, collocation dictionaries and spell checkers are widely known, NLPTs appear to be generally underused in foreign language teaching. It was found that teachers prefer computer-based environments over mobile devices such as smartphones and tablets and that teachers' qualification determines their familiarity with a wider range of OER NLPTs. This research offers insight into future applications of Language Processing Technologies as OERs in language learning.

This research uses the theoretical framework of CALL normalisation developed by Bax (2003) and Chambers & Bax (2006) to offer a systematic review (Gough et al., 2012) of the uses and spread of data-driven learning (DDL) and corpora in language learning and teaching across five major CALL-related journals during the 2011-2015 period. DDL research represented 4.2% of all published papers on CALL during this time frame. The main focus of research was found to be the use of concordancing and collocations when developing university students' writing skills. Contrary to previous research, access to technology was not identified as an impeding factor for normalisation. Syllabus integration and a lack of contribution from language teachers other than researchers emerged as threats to the normalisation of corpora use. Further theorisation is needed if DDL and corpora are to expand their influence on mainstream second language education.

The Teacher-Student Chatroom Corpus (TSCC) is a collection of written conversations captured during one-to-one lessons between teachers and learners of English. The lessons took place in an online chatroom and therefore involve more interactive, immediate and informal language than might be found in asynchronous exchanges such as email correspondence. The fact that the lessons were one-to-one means that the teacher was able to focus exclusively on the linguistic abilities and errors of the student, and to offer personalised exercises, scaffolding and correction. The TSCC contains more than one hundred lessons between two teachers and eight students, amounting to 13.5K conversational turns and 133K words: it is freely available for research use. We describe the corpus design, data collection procedure and annotations added to the text. We perform some preliminary descriptive analyses of the data and consider possible uses of the TSCC.

His main research interests are quantitative research of register variation and the compilation and use of language corpora in the field of applied linguistics. He is an Official Translator appointed by the Spanish Ministry of Foreign Affairs and for many years was in charge of the teaching of legal English at the Faculty of Law in the University of Murcia, Spain. His book Researching Specialized Languages, co-edited with V. Bhatia and P. Sánchez, John Benjamins, was awarded the "Enrique Alcaraz" research award by the European Association of Languages for Specific Purposes in 2013.
