Krashen on Grammar

Dr. Krashen states:
There is nothing wrong with talking about grammar occasionally. Eric Herman stated my position about grammar and output very well on your blog. Even a dictation once in a while (especially as it relates to French culture!).
In fact, doing a little grammar, etc. is a good chance to discuss language acquisition theory, e.g. the limits of grammar (not forbidden, but it is limited) and output (can encourage input, makes you feel good).
