The book begins by introducing fundamental linguistic concepts and essential terminology used in SLA research. It then traces the historical development of the field, examining the transition from behaviorist perspectives to cognitive and interactionist approaches.
Particular attention is given to the concept of interlanguage, developmental sequences, formulaic language, first-language influence, and the role of input, intake, and output in language learning. The volume also introduces key research methods employed in SLA studies, enabling readers to understand and critically evaluate empirical findings.
Throughout the book, theoretical discussions are accompanied by examples drawn from authentic learner language and influential empirical studies. These examples are intended to illustrate how learners actively construct linguistic systems and how language acquisition emerges from the interaction of cognitive, linguistic, social, and environmental factors.
This book is primarily intended for undergraduate and graduate students in applied linguistics, linguistics, language education, TESOL, and related disciplines. It may also serve as a useful resource for language teachers who wish to deepen their understanding of the processes underlying language learning.
