I’m often puzzled when I see Higher Ed lectures be so effective without any technology. Our learning styles of yesteryear were very focused. Academicearth.org is a neat example of how higher ed can be efficient with little use of technology. We often overemphasize the need for technology and equate GOOD teaching with MORE technology. That often is not the case.
I totally agree with you Kev, on all points. Let's not forget that some students also prefer to see main points in writing (some are dyslexic), others are visual types, not to mention that not everybody is English and it is easier to see new ideas and possibly new vocabulary written on a screen...
I wish Microsoft spent a little time updating poor PowerPoint however, it does look awfully outdated and static! Or maybe another company could produce a new software altogether. Prezi looks a lot more sophisticated, but I haven't used it yet, so I can't comment more on pros and cons.
