“This book provides practical guidance for applied linguistic students doing SLA research. Each chapter, written by an expert in a subfield of second language acquisition (SLA), first presents a brief background review and theoretical frame-work of that area of research, then provides guide to the research methods and, finally, presents studies adopting the particular method to give readers a sense of practicality.” (The Modern Language Journal, 21 November 2013)“Each of the 15 chapters is comprehensive and accessible, and together they are bound to provide a thorough practical guide for students as they engage in various research projects. The volume will also prove to be a useful reference book for anyone teaching research methods in the context of SLA.” (Studies in Second Language Acquisition, 20 May 2012) “This volume ultimately deserves strong praise for its wide-ranging representation of current topics and procedures in SLA research. Although intended for students, it guides all scholars to a better understanding of how we study our field and is an important addition to the library of all SLAresearchers, novice or seasoned.” (LINGUIST, 19 May 2012)
