In this book the authors take a closer look at spelling, the teaching and learning of which is considerably more complex than is often assumed. In order to spell well, children need to learn how to strategically use knowledge about phonology, orthography, morphology and etymology. It is also a visual activity that involves the laying down and retrieval of visual representations of words and word parts in memory. Children also need to learn how to use the metalanguage associated with spelling - words like phoneme, syllable, affixes and morpheme - as this will help them talk and think about spelling strategies. Thus, spelling is a language activity and also a thinking activity. Ideally, it should also be a meaningful activity that is engaged in with a positive attitude. The authors draw on the theoretical and research literature, as well as classroom examples, to explain how to teach primary school aged children to use multiple strategies to spell. They also consider the assessment of spelling, as well as how to assist those who have difficulties in learning to spell.The work makes links to the Australian Curriculum: EnglishThis book would help primary and preservice teachers by providing them with understandings, based on research and theory, which would help them choose and use appropriate pedagogical strategies (also provided in the book) to teach spelling to children with diverse needs, including children from EAL/D backgrounds and those with difficulties and disabilities that impact on spelling.

This distinctive cross-linguistic examination of spelling examines the cognitive processes that underlie spelling and the process of learning how to spell. The chapters report and summarize recent research in English, German, Hebrew, and French. Framing the specific research on spelling are chapters that place spelling in braod theoretical perspectives provided by cognitive neuroscience, psycholinguistic, and writing system-linguistic frameworks. Of special interest is the focus on two major interrelated issues: how spelling is acquired and the relationship between reading and spelling. An important dimension of the book is the interweaving of these basic questions about the nature of spelling with practical questions about how children learn to spell in classrooms. A motivating factor in this work was to demonstrate that spelling research has become a central challenging topic in the study of cognitive processes, rather than an isolated skill learned in school. It thus brings together schooling and learning issues with modern cognitive research in a unique way. testing, children writing strings of letters as a teacher pronounces words ever so clearly. In parts of the United States it can also bring an image of specialized wizardry and school room competition, the "spelling bee." And for countless adults who confess with self-deprecation to being "terrible spellers," it is a reminder of a mysterious but minor affliction that the fates have visited on them. Beneath these popular images, spelling is a human literacy ability that reflects language and nonlanguage cognitive processes. This collection of papers presents a sample of contemporary research across different languages that addresses this ability. To understand spelling as an interesting scientific problem, there are several important perspectives. First, spelling is the use of conventionalized writing systems that encode languages. A second asks how children learn to spell. Finally, from a literacy point of view, another asks the extent to which spelling and reading are related. In collecting some of the interesting research on spelling, the editors have adopted each of these perspectives. Many of the papers themselves reflect more than one perspective, and the reader will find important observations about orthographies, the relationship between spelling and reading, and issues of learning and teaching throughout the collection.

The origins of learner corpus research go back to the late 1980s when large electronic collections of written or spoken data started to be collected from foreign/second language learners, with a view to advancing our understanding of the mechanisms of second language acquisition and developing tailor-made pedagogical tools. Engaging with the interdisciplinary nature of this fast-growing field, The Cambridge Handbook of Learner Corpus Research explores the diverse and extensive applications of learner corpora, with 27 chapters written by internationally renowned experts. This comprehensive work is a vital resource for students, teachers and researchers, offering fresh perspectives and a unique overview of the field. With representative studies in each chapter which provide an essential guide on how to conduct learner corpus research in a wide range of areas, this work is a cutting-edge account of learner corpus collection, annotation, methodology, theory, analysis and applications.

Errors in Language Learning and Use is an up-to-date introduction and guide to the study of errors in language, and is also a critical survey of previous work. Error Analysis occupies a central position within Applied Linguistics, and seeks to clarify questions such as `Does correctness matter?', `Is it more important to speak fluently and write imaginatively or to communicate one's message?' Carl James provides a scholarly and well-illustrated theoretical and historical background to the field of Error Analysis. The reader is led from definitions of error and related concepts, to categorization of types of linguistic deviance, discussion of error gravities, the utility of teacher correction and towards writing learner profiles. Throughout, the text is guided by considerable practical experience in language education in a range of classroom contexts worldwide.
