How geography professors select materials for classroom lectures: implications for the design of digital libraries

A goal of the Alexandria Digital Earth Prototype (ADEPT) project is to make primary resources in geography useful for undergraduate instruction in ways that promote inquiry learning. The ADEPT education and evaluation team interviewed professors about their use of geography information as they prepare for class lectures, as compared to their research activities. We found that professors desired the ability to search by concept (erosion, continental drift, etc.) as well as geographic location, and that personal research collections were an important source of instructional materials. Resources in geospatial digital libraries are typically described by location, but are rarely described by concept or educational application. This paper presents implications for the design of an educational digital library from our observations of the lecture preparation process. Findings include functionality requirements for digital libraries and implications for the notion of digital libraries as a shared information environment. The functional requirements include definitions and enhancements of searching capabilities, the ability to contribute and to share personal collections of resources, and the capability to manipulate data and images.
