Note-shameless self-plug coming. Kendall/Hunt will be publishing my textbook with release this coming fall (in a real, full-published form), so don't forget to include it as well in your looking around. It is aligned with much of the current research about integrated instructional units and learning theory that's coming out from NSF and other such organizations. More information at www.reallifechemistry.net <http://www.reallifechemistry.net/> or ask me Kelly
