Advancing Quantitative Methods in Second Language Research is the first hands-on guide to conducting advanced research methods in the fields of applied linguistics and second language studies. While a number of texts discuss basic quantitative research methodology, none focus exclusively on providing coverage of alternative advanced statistical procedures in second language studies from a practical approach. The text is bookended by discussions of these advanced procedures in the larger context of second language studies, debating their strengths, weaknesses, and potential for further research; the remaining chapters are how-to sections, each chapter following the same organization, on a wide variety of advanced research methods. By offering much-needed coverage on advanced statistical concepts and procedures, with an eye toward real-world implementation, Advancing Quantitative Methods in Second Language Research enhances the methodological repertoire of graduate students and researchers in applied linguistics and second language studies.

Written in a detailed and fascinating manner, this book is ideal for general readers interested in the English language.

Instruments for Research into Second Languages is an accessible introduction to understanding and evaluating existing and emerging methodologies in L2 research. The book provides an introduction to the data collection materials available in the IRIS database. IRIS is an open access, searchable repository of instruments used to elicit data for research into second and foreign language learning and teaching. The book is aimed at graduate students, researchers and educators in the fields of Applied Linguistics and Second Language Acquisition. Featuring contributions from top scholars in the field, this dynamic volume includes empirical research carried out using innovative instruments held in IRIS, offering insights into their basic mechanics, how and why they are used, as well as the challenges they can present. The chapters describe the kinds of data (evidence about knowledge, processing, interaction, learning, and motivation) that result from these methods, and they discuss conditions that lead to reliable and valid data collection and analysis. This unique collection provides researchers, professionals, and students with up-to-date responses to practical and theoretical questions about how second language learning and teaching can be investigated using the IRIS database of instruments. IRIS was funded by the Economic and Social Research Council and is a long term British Academy Research Project.
