The last decade has seen a growing number of L2 studies of children aged 4-12, a demographic with special developmental characteristics that confound research methods designed for studying adults. Written by experts from a variety of disciplines, this book covers major research methods and techniques in existing L2 development research, including observations, surveys, interviews, introspective methods, speech production methods, receptive methods, eye tracking, and brain imaging, as well as research methods specifically designed for L2 children with special educational needs. The book also discusses various age-related considerations and challenges if they are employed to young L2 learners.

This will be essential reading for SLA, child development, and TESOL researchers, and students in these courses will benefit particularly from pedagogical material such as further readings and discussion questions.
