I can’t find anywhere in Krashen, although I don’t have much time any more to look thoroughly, where he talks about communication as awareness.
There is one passage that is kind of connected. This is from a paper (I’ll give the source later) that Krashen wrote about something Roger Brown said:
This is Krashen:
“After reviewing research on how caretakers talk to children, [Roger] Brown offered this advice in answer to the question, “How can a concerned mother facilitate her child’s learning of language?” “Believe that your child can understand more than he or she can say, and seek, above all, to communicate. To understand and be understood.” (Brown, 1977, p. 26).
“The same, I am hypothesizing, holds for second language acquisition.”
Brown’s term of “seek, above all, to communicate” I don’t believe has not been heard at a deep enough level by the TPRS community. There seems to be some interest in the phrase, in authentically communicating, but it is has not been discussed, to my knowledge, in a truly substantive way.
More important to many current TPRS teachers is to find a way to teach the subjunctive using a snappy technique.Or to find a game to help teach object pronouns. This is to TPRS as a needle to a balloon.The students in such a classroom don’t need to be aware of each other at all to do those things.
So we need to look at what communication is.
