Re: Spoon feeding or research?
Well, yes, that is a point - but I think that this sort of thing can be done in different ways. For example, at the Science Museum's new gallery, which I wrote about a few months back, there are interactive displays that allow you to either look at the quick summary, or to read a bit deeper into the background. I'd like to see more of that, ideally with options for both kids and adults.
If interactive displays can't be provided, because of cost, since most of us do have a portable device when we're visiting, it wouldn't be too hard to provide short URLs or QR codes either - again, with a little work, you could have multiple ones, for different key stages, experts, and so on.
It certainly is hard to pitch information at a level that will please everyone, but it seems to me that one of the great advantages of modern technology is that you can provide alternatives, even if it's only a few links to further reading, without too much effort.
