Presents the use of geographic information system (GIS) technology in the laboratory section of an upper-level college course in soil physics. The laboratory includes a lecture portion that provides an introduction to GIS and selected applications to soil science, agriculture, and environmental sciences. (LZ)

We describe our pedagogical approaches and experiences with a novel course in agroecology (one semester, three credit-hours, for graduate students and upper level undergraduates). Our course responds to recent proposals that agroecology expand its disciplinary focus to include human factors as well as ecological factors, thus taking a more…
