Former Peace Corps volunteer and sometime Tae Kwon Do champion Professor Stephen D. Krashen established himself as the black-belt master of the SLA world with this powerful review of the research and case study literature, mostly his own, in the fields of second language acquisition and second language learning which received the Mildenberger Award in 1982.
The nine-chapter volume can be a little heavy going at times as the professor reels-off stats like so many lighting kicks to support his revolutionary hypothesis, including the acquisition-learning hypothesis, the input hypothesis, the monitor hypothesis, the affective filter, and the natural order hypothesis, which all make formative appearances here.
Nothing however escapes his kung-fu grip in this thoroughly involving study which, unusually for this still vastly under-researched field, attempts to answer as many questions as it raises and as such while his research may now be a little dated his hypothesis remain intriguing and are now available to download free of charge from the author’s website.
There is valuable teacher-talk to listen to (on a topic I happen to be interested in, grammar: I realize that I am a member of perhaps a small minority). - Stephen D. Krashen
