Not a million miles from what I said earlier, is it?
. . . in the case of presentations they could (as a class) start by something like being asked to stand up when addressing the class, eg answering a question, and take it in stages from there. I doubt they would go from nothing to a full-blown presentation in one go, which would be asking a lot.
Obviously a lot would depend on how much time was available to devote to that part of the syllabus, but a similar approach, which suggests that either you are wrong about my 'paying lip service' to sensitivity to differing abilities, or you see yourself as being insensitive too.
Either way, you have been deeply offensive to me, based on my comments about how in a university situation - one in which students are selected on the basis of their declared ability to complete a course, and are graded on a pre-determined set of skills, which fit a grid that is used by all HE institutions, it is impossible to differentiate between students when it comes to assessments, particularly in these days of high fees and litigious parents, many of whom want preferential treatment for their own children and scream 'unfair' when others appear to be given such treatment.
