This textbook takes a Complex Systems Theory approach to examine
individual differences between learners and the potential impact of
these variables on the process of acquiring a second language. The
authors argue that individual variables cannot provide the complete
picture, and that they must instead be understood as part of an
interconnected and dynamic system of different factors in order to be
useful in a language learning context. Written in an accessible style
and suitable for final-year undergraduate and Masters-level students,
the book includes clear definitions of key terms, discussion questions
for classroom use, practical exercises and activities, and examples of
real empirical studies that students and teachers can replicate in their
own contexts. This textbook will be of interest to students taking TESOL
and SLA courses and modules, as well as those on broader Applied
Linguistics programmes.
