The objective of this workshop was to provide faculty with hands-on training in the use of Web-based instructional methods for spe- cific application to the teaching of satellite remote sensing in their subject areas. More than 150 faculty and associated scientists participated, and postworkshop evaluation showed it to have been a very successful integration of information and activities related to computer-based instruction, educational principles, and scientific lectures. 1.
