Should children be taught a comprehensive understanding of English grammar?

Interesting interview with Simon Heffer about his crusade to improve the teaching of English grammar. he argues that most pupils have been left with “nothing but a random and often erroneous understanding of the components of language”.

What do you think?

I went to a very old fashioned grammar school and had English Grammar lessons which have stood me in good stead. However, before coming to France I did a TEFL course and one of my fellow students was a Polish guy, who knew more about English Grammar than all of us put together…stuff like the third conditional, that I’d never even heard of!
I think it’s vital to have some knowledge of English grammar to be able express oneself correctly and to understand information. Once you know the basic rules, you can play around a bit and enjoy yourself.

I don’t know about comprehensive, but more wouldn’t be a bad thing. As far as I know though, they are being taught about verbs, adverbs, adjectives, and so on, and I know because I’ve been writing some educational resources that do so.

Things can’t be worse than when I was at school in the 70s and the only grammar we got taught was in French. Why did we need it in French and not English, one wonders.
