Chapter 2
Quantitative research methods in ISLA

| Florida State University
This chapter provides a comprehensive, in-depth discussion of quantitative research methods in ISLA. It starts by informing the reader of the basic elements and principles of quantitative ISLA research and the major research questions examined. It then identifies three categories of ISLA research: experimental, correlational, and observational, followed by a discussion of the methods for evaluating the quality of quantitative research from the perspectives of construct validity, internal validity, external validity, and statistical conclusion validity. The chapter proceeds to offer advice for future researchers on how to carry out original and robust quantitative research and propose strategies to address common methodological issues. A conclusion is offered at the end.
Keywords: quantitative research methods, instructed second language acquisition, experimental research, correlational research, observational research
