Accuracy across proficiency levels : a learner corpus approach

This volume is a corpus study of the construet of accuracy by learners of English as a Foreign Language based on the International Corpus of Learner English. Accuracy is analysed from a developmental point of view at four consecutive levels of language proficiency (B1, B2, C1, C2), thereby providing insights into areas of progress, stabilisation and regression. Written within a computer-aided error analysis research framework, this volume offers valuable information about the development of more than forty error types in a wide variety of domains such as grammar, lexis, lexico-grammar, spelling and punctuation. It provides important methodological considerations for developmental learner corpus research, presents abundantly illustrated analyses of authentic learner errors as well as suggestions for improving the descriptors of the Common European Framework of Reference for Languages.
