I spent 2-3 hours browsing through a variety of good material that I thought could be useful for several courses in an interior design program.
The materials I found were all under civil engineering. Finding the material could have been difficult and possibly discouraging to a regular student. However, once you got a feeling for how the site works, navigating it was fine. The site itself is treated as a building/engineering/architectural site but it is quite informative for faculty and students in an interior design program of study. I never got to the earthquake demonstration; it would have taken another 2 hours.
If used appropriately, the site has the potential of enhancing teaching and learning. Teaching because of the resources available in a single site, learning because of the richness of the material.
First time users will find the site friendly and useful; however, people doing research may find that it needs to be cataloged differently to prevent one from diverting and jumping among the different subject matters.
