This textbook offers an introductory overview of eight hotly-debated topics in second language acquisition research. It offers a glimpse of how SLA researchers have tried to answer common questions about second language acquisition rather than being a comprehensive introduction to SLA research. Each chapter comprises an introductory discussion of the issues involved and suggestions for further reading and study. The reader is asked to consider the issues based on their own experiences, thus allowing them to compare their own intuitions and experiences with established research findings and gain an understanding of methodology. The topics are treated independently so that they can be read in any order that interests the reader.
