Index

This volume showcases original, agenda-setting studies in the field of learner corpus research of both spoken and written production. The studies have important applications for classroom pedagogy.
The volume brings readers up-to-date with new written and spoken learner corpora, often looking at previously under-examined variables in learner corpus investigations. It also demonstrates innovative applications of learner corpus findings, addressing issues such as the effect of task, the effect of learner variables and the nature of learner language.
The volume is of significant interest to researchers working in corpus linguistics, learner corpus research, second language acquisition and English for Academic and Specific Purposes, as well to practitioners interested in the application of the findings in language teaching and assessment.
