What Jane so rightly describes here is, apart from common sense, an approach favoured by a number of other language teaching and learning specialists. I’m reblogging this useful article as it might save a few repeated explanations. It had been on my list of things to do for a long time – here, you can benefit from another language tutor’s input.
If you are a language student and would like to make progress as rapidly as possible, try to remember NOT to respond “OK”/”Oh, OK”/”Ahh, right…” (etc.) after feedback or a correction. Repeat the new language and practice making the connection from thoughts to words!
I hope this helps.
