Let us hope that "ICT" is dead and buried
I think we are very close on this one - and I agree that the general discussion is an interesting one. I think it also parallels an educational discussion about the point at which you move to vocational courses. If it is the application of subject knowledge rather than its fundamental principles that have changed, then too much emphasis on technological application may represent a premature move to vocational training.
At the same time, I think that abstract principle needs to be contextualised in a variety of challenging and compelling ways. E.g. what maths was used to work out the mass of the Siberian meteorite? My only quibble is that this is a function of pedagogy and not curriculum (i.e. top level learning objectives).
I echo your call for more contributions to the discussion!
