Do you emphasize on grammar rules when teaching? Do you get them to handle exceptions later, teach the rules and the exceptions together, or ignore exceptions and let them find out themselves?
Pretty confusing, isn't it?[/quote]
I personally teach the rules and handle exceptions later. In Emile's example , present simple versus present continuous
the basic rules are not too complicated although some of my students can't see the difference between a state verb and an action verb and in French, it's the same!!! So I make a list.
For older students I teach the exceptions .
Ex :She teaches maths in a school in Bonn. ( permanent)
She is teaching Maths in a school in Bonn. ( temporary)
My younger students can't handle the difference between these two sentences but my older students can .well, I hope so!!!
