Steven Krashen is thought to be a linguist, but my impression is that his famous propositions are closely related to the psychology of learning, which has remarkably developed in the United States of America as a scientific discipline.
I am not a psychologist. I just wrote the above sentences to practice writing in English. You don’t have to believe what I wrote.
Yes, thanks a lot Don. Krashen is not always right, but right on most things in my view. An inspiration. I kind of feel that LingQ is one of the few systematic applications of Krashen’s ideas with a few differences.
He is very strong on reading, we add the audio and listening.
He recommends extensive reading of graded material, we suggest you jump in over your head if you are interested.
He tends to discount deliberate vocabulary review, output and correction, we provide some, as much as you want.
