I don't like percentage plots. If one thing goes up by 1 point, then the rest must necessarily go down by 1 point (distributed between them). I think that's a bit confusing. I'd much prefer absolute values.
4 small groups of students (pairs or triples) repeated enough times to cover whole class. Each group gets one of these three charts or the table. Plenary at end: the ones who got the % bar chart often have totally different sentences from the other three groups.
I tend to give the % bar chart to the more confident students.
Personally, show me the numbers. Wins every time.
If they aim is to communicate a true representation of reality then you need to take that into account.
