Recently I had the opportunity to sit in on a demonstration of GIS Software to a group of teachers at a high school in Brooklyn, NY. The school had just purchased the software for its computer lab (I never found out which particular version of this software was being demonstrated) and an instructor was demonstrating how the maps represented all sorts of geographic information from population to agriculture to environmental trends.
Seeing a demonstration such as this with a group of teachers is a real treat. We all saw the instructional potential of such a tool. However, before anyone could get too excited about the software’s potential for fueling creativity and curiosity in students, there were questions posed by the teachers about the ability of GIS software to represent accurate information. What are its sources? When is data refreshed? After all, teachers need to know what lessons they can teach, and what information can be accurately provided with the tools provided to them.
Often, a new technology (new to the particular environment, anyway) is introduced with very little understanding by the administration about its real-world application. At times this has led to new technologies introduced and quickly left to languish when no teacher or student has any idea how to use it to further their lessons and projects. It boils down to a big question, namely, “Am I teaching the tool or am I teaching the subject?” It is a question being pondered whenever a new tool promises big returns in education. Or, as we’ve lately seen in the world of “Library 2.0“.
Students and teachers can and should take any opportunities to learn to use new technologies together, it is no longer imperative that teachers be experts in the use of technology before bringing it to students. In the classroom, it’s not the technologies that are important, it’s the learning. But teachers and school administrators will want to know how they can apply software to take full advantage of its capabilities for teaching. Use of GIS, for example, merely to illustrate data, though important in its way, fails to demonstrate how use of the software enables more difficult calculations and leads to more refined results. It also fails to acknowledge that the reliability of the data itself is the basis of that refinement. High school students – natives of the Internet and gadget-adepts – will naturally understand the relationship of the raw data to its visual representation. What may be more difficult to grasp is the importance of the currency of the data and the use of the maps to infer other, less tangible information.
One could teach an important lesson in this regard simply by asking the rhetorical question, “There’s a hurricane approaching. Is the data in our software the same as the data given to us by mintue-to-minute by The National Weather Service? If your software tells a different story from the NOAA, which data do you trust?” The fact that the GIS map is only as good as its data is the first lesson in the proper application the software. Too often, however it is a lesson that unintentionally repeats itself throughout the rest of the school year.
