How Languages Are Learned 5th Edition by Patsy M. Lightbown

An Introduction to Second Language Acquisition

An accessible overview that summarizes core research and theories of first and second language acquisition and links them to classroom practice: how learners develop grammar and communicative skills, the roles of input, interaction, corrective feedback and explicit instruction, and how age, motivation, aptitude and learning context influence outcomes. It evaluates common teaching approaches and activities, discusses implications for syllabus design and assessment, and highlights recent findings to help teachers make evidence-based decisions about classroom practice.
