InterChemNet (ICN, http://icn2.umeche.maine.edu/newnav/NewNavigator/LoginForm.cfm) is a web-based laboratory management and curriculum delivery system that incorporates spectroscopic instrumentation, student choice, and assessment of student learning. Data from studies evaluating spectroscopy curriculum modules in terms of assessment of student learning are presented. We discuss the use of ICN as a tool for action research in the laboratory setting, focusing on two modalities that can be facilitated with this technology: parallel curriculum improvement cycles and multi-campus assessment.
