ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book explores second language acquisition (SLA theory), research, and second language (L2) pedagogy with the goal of helping researchers and practitioners. It aims to provide explicit connections between SLA theory, research, and practice, learn about and conduct classroom research to contribute to the relevance and applicability of SLA research and improve L2 curriculum and instruction in light of theory and research. The book offers a description of basic theories and their implications for the learning of the target language skill. It also aims to offer teachers the opportunity to claim and enact a practitioner-researcher agency, contributing to the enterprise through inductive generation of new theories and action-research to improve current L2 curriculum and instruction. The book also explores the last piece of the puzzle, by aligning classroom activities with the specific theory and research about each language skill.
