What is Corpus Linguistics and Corpora

Technological innovation in supporting feedback on writing is well established in computer-assisted language learning (CALL) literature. Regarding writing development, research has found that intelligent CALL systems that respond instantly to learners' language can support their production of better-written texts. To investigate this claim further, this chapter presents a study on learner use of Write & Improve (W&I). The study, based on learner engagement with W&I and learner and teacher surveys and focus groups, demonstrates that learners find W&I to be engaging and motivating. Moreover, there is evidence of improvements in learner writing practices and written language proficiency. For teachers, W&I can render feedback more efficient, allowing them to focus on more complex aspects of learner texts, while spelling and syntactic accuracy are addressed by W&I. Issues also emerge in the use of W&I, which present problem areas for teachers and learners and which signal important future considerations for CALL research.
