This volume illustrates the high potential of learner corpus investigations for research into the CAF triad by presenting eleven original learner corpus-based studies which are set within solid theoretical frameworks, examine learner corpora with state-of-the-art analytical techniques and yield highly interesting findings. The volume’s major strength lies in the range of issues it undertakes and in its interdisciplinary thematic novelty. The chapters collectively address all three dimensions of L2 performance related to different linguistic subsystems (i.e. lexical, phraseological and grammatical complexity and accuracy, along with fluency) as well as the interactions among these constructs. The studies are based on data drawn from carefully compiled learner corpora which are analysed with the help of diverse corpus-based methods. The theoretical discussions and the empirical results shall contribute to the advancement of the fields of SLA and writing and speech research and shall inspire further investigations in the area of the CAF triad.

While native corpora and corpus linguistic tools and methods have been used and applied for quite some time in the development of learning and teaching materials, learner corpora are only just beginning to impact the field of language teaching, testing and assessment. This volume helps to close this still existing gap and highlights the great potential of learner corpus research for language pedagogy by presenting a selection of 11 original studies on learner corpora, conducted by established experts as well as by excellent young researchers. The papers included in the volume present new corpora and methods; studies on written as well as spoken learner corpora and on using data-driven learning scenarios in the classroom.All papers include sections on practical and concrete language-pedagogical applications. This volume will be 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 language teachers and materials developers.

At a time when the paradigm gap (Sridhar & Sridhar 1986) between the EFL and ESL research areas is attracting much scholarly attention, the contributions in the current volume explore this gap from the perspective of linguistic innovations across the two different types of non-native Englishes. In this endeavour, this volume unveils the many facets of linguistic innovations in non-native English varieties and explores the fine line between learners' erroneous versus creative use of a target language. Adopting empirical, corpus-based approaches to portray linguistic innovations characteristic of EFL and ESL varieties, the contributions show how the interaction of linguistic and social forces influences the development of novel linguistic forms in both endonormative ESL contexts and exonormative EFL contexts. This volume is of relevance to linguists who are interested in the features of non-native English and who wish to gain a better understanding of the nature of innovations along the EFL - ESL continuum.Originally published as a special issue of International Journal of Learner Corpora Research 2:2 (2016).

The aim of this volume is to highlight the benefits and potential of using learner corpora for the testing and assessment of L2 proficiency in both speaking and writing, reflecting the growing importance of learner corpora in applied linguistics and second language acquisition research. Identifying several desiderata for future research and practice, the volume presents a selection of original studies, covering a variety of different languages. It features studies that present very thoroughly compiled new corpus resources which are tailor-made and ready for analysis in LTA, new tools for the automatic assessment of proficiency levels, and new methods of (self-)assessment with the help of learner corpora. Other studies suggest innovative research methodologies of how proficiency can be operationalized through learner corpus data. The volume is of particular interest to researchers in (applied) corpus linguistics, learner corpus research, language testing and assessment, as well as for materials developers and language teachers.
