ITForum is quite diverse these last few days. But, I had thought the difference issue had long passed--why should any technological resource be better than another? I've always argued that if the appropriate analysis is done, then the correct resource(s) will be selected for the learning/instructional activity. If one form of instruction is shown to be better than another, then it would suggest that the "better" form is only using more appropriate resources. Conversely, no difference simply means one is as good as the other.
When we get NEW technologies--overhead projectors, TV, PCs, color monitors, Hyper-stuff, Multimedia, etc., all we are doing is adding to the set of resources which can be used for teaching and learning. As we go about designing new materials we have access to a wider range of resources which can be incorporated as required. Our challenge is to understand these new resources in terms of the means by which they can provide educational support.
