New PEG-based hydrogel materials have been synthesized by Click chemistry and shown to result in well-defined networks having significantly improved mechanical properties; the selectivity of the azide/acetylene coupling reaction also allows for the incorporation of various additives and functional groups leading to chemical tailoring of the hydrogels.

This paper describes the physical attributes and uses of an integrated learning environment for a large-enrollment general chemistry course sequence. The room was opened in Spring Quarter 1997 and 2000 students have passed through its doors since then. The facility is one in which experimentation, collaborative student involvement, lecture, technology, and individual attention can be maximized for more effective learning (1). With it we hope to foster a healthy spirit of pedagogical experimentation in a modern technological environment-education for a new millennium. See our Web site at http://chemweb.calpoly.edu/chem for links to laboratory experiments, current instructors' pages, and other course materials.
