The College of Agriculture and Life Sciences (CALS) and the university's Information Technology Division (ITD) are collaborating to implement wireless proximity services for a classroom suite in Williams Hall. The investigators will test and install a WideRay jack unit designed to disseminate classroom resources and materials via short-range infrared or bluetooth signaling. Students in Crop Science 213 (Crops: Adaptation and Utilization) will participate in a pilot study, downloading lab worksheets, manuals, and templates from the WideRay onto handhelds and data-enabled cellular devices. The WideRay unit will be mounted in a public space between a student laboratory and lecture hall, allowing the investigators to test the dissemination of different types of classroom (assignments, code, images, powerpoint slides) and non-classroom information (maps, guides). Surveys and observations will be used to describe relative advantages to proximity delivery of information over more traditional means of access to this same information (i.e., print-based handouts, posting files on WebCT or WolfWare, e-mailing files to students).
