Understanding lunar phases requires 3-D information about the relative positions of the Moon, Earth, and Sun, thus using a stereo display in instruction might improve student comprehension of lunar phases, or other topics in basic astronomy. We conducted a lab (15 sections) on phases of the moon as part of the introductory astronomy classes. Half of the labs were taught using stereo visualizations projected by a portable GeoWall system running the AstroWall software, while the other half of the labs were identical, but without stereo. We found that both sets of labs showed a statistically significant gain in student comprehension, but that there was no statistical difference between the stereo labs and the non-stereo labs. We conclude that there is no advantage to using a stereo display in teaching about lunar phases.
