USING THE GEOWALL TO INCREASE SPATIAL UNDERSTANDING IN AN INTRODUCTORY-LEVEL FIELD CLASS
The GeoWall exercise occurred during a pre-field laboratory. Students map contacts and describe the geologic setting of SP Crater using black and white, stereo, 1:25000 aerial photographs and mylar overlays. The intervention added to this instruction by requiring the students to individually use a stereo 3D visualization of SP Crater rendered with the ROMA software in the GeoWall. The intervention included an assessment that required students to "fly" to various predetermined points of interest and describe the geologic setting at those points using well-defined rules. The lab exercise was followed by a field mapping day at SP Crater. The GeoWall was also available to students during the report-writing phase of the exercise in the following week.
Results of the intervention based on interviews between the lab and field exercises and a written summative assessment at the end of the project indicate a strong positive attitude toward the use of the GeoWall, and an expectation for access to 3D visualization technology both in education and career. Student comments included a more realistic approach than the stereoscope and ability to map in 3D greatly diminished my ability to get lost, as well as the problem was that we had too many people at once. With the lessons from F03, we will improve the presentation in the class during F04.
