This paper describes the development of technologies employed in customizing MapCafé and the ArcView Internet Map Server extension for teaching analytical applications of GIS in archaeological research. We detail the development of programming code that permits intercommunication between HTML, JavaScript, and MapCafé as well as Avenue scripts that provide the basic functions necessary to accomplish this end in any classroom setting. These developments allow for more advanced query, analysis, and retrieval functions with GIS served over the Web, thereby providing interactive exploratory data analysis environments. The technologies described can facilitate student interaction with high-level GIS functions in any WWW classroom context.
