One of the biggest problems teacher face is classes

 wherethe students are at different levels-some with quite

 competent English, some whose English isn’t very good,

 and some whose English is only just getting started. Even if

 things are not quite so extreme, teachers of English –

along with teachers of other curriculum subjects-regularly

 face mixed ability groups where different individuals are

 at different levels ?and have differentabilities. What then

 are possible ways of dealing with the situation
