Learning Benefits of Using 2D versus 3D Maps: Evidence from a Randomized Controlled Experiment

The traditional important role of maps used for educational purposes has gained further potential with recent advances in GIS technology. But beyond specific courses in cartography this potential seems little realized in geography teaching. This article investigates the extent to which any learning benefits may be derived from the use of such technologies. A controlled experiment was conducted to examine whether information recall is improved when cartographic information on population distribution is presented in 2D versus 3D form. The results show statistically significant differences in learning benefits between the two formats, largely in favor of 2D representation. These findings suggest that learning benefits can be derived from paying greater attention to map format in educational settings. (Contains 2 tables and 1 figure.)
