Inclusion is important and like you said, some benefit from inclusion and others don't. We have a few learners at our school who is intellectually disabled and what worries me is that they just can't cope with the work load. Since we only have one class per grade they have to be in with all the other learners. The main problem we are experiencing with this is that they are struggling as well as the intellectually "normal" learners are struggling, because they have to be held back because of these learners.
One class per grade! Oh no!
