Papers now available for printing

I have now posted Acrobat versions of the two introductory papers on Threshold Concepts for the Study Days, so that they can be printed; printing the web-pages directly leads to the ends of lines being cut off, etc.
I haven't done the "Fitting in" paper; it has an external link in almost every paragraph, so it is intended for use on screen.

For all you PowerPoint fans out there!

Fun presentation of some of the easier shots at PPt; see also http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=00001B&topic_id=1&topic=Ask+E%2eT%2e for some of the more interesting ones.

Topic for Interest Groups

This may change, but it does look promising. We have posted several pages to help you get your heads around the notion of "threshold concepts and troublesome knowledge". Please enjoy and feel free to comment.
