Pre- and post tests are the same, and should be admisnistered to the same group of students before and after your GPS/GIS project(s) are conducted. I am very interested in how students answer question # 4- where they are asked to circle the sources of pollution to Chesapeake Bay. What I would like to know is how many circle "acid rain," how many circle "bacteria" etc.
