Krashen's widely known theory of second-language acquisition has had a huge impact on all areas of second-language research and teaching since the 1970s. This book amounts to a summary and assessment by Krashen of much of his work thus far, as well as a compilation of his thoughts about the future. Here, readers can follow Krashen as he
  • reviews the fundamentals of second-language acquisition theory
  • presents some of the original research supporting the theory and more recent studies
  • offers counterarguments to criticisms
  • explores new areas that have promise for progress in both theory and application.
An invaluable resource on the results of Krashen's many years of research and application, this book covers a wide range of topics: from the role of the input/comprehension hypothesis (and its current rival—the comprehensible output hypothesis), the still-very-good idea of free voluntary reading, and current issues and controversies about teaching grammar, to considerations of how it is we grow intellectually, or how we "get smart."
