| Popis: | The augmented reality (AR) sandbox bridges the gap between two-dimensional (2D) and three-dimensional (3D) visualization by projecting a digital topographic map onto a sandbox landscape. As the landscape is altered, the map dynamically adjusts, providing an opportunity to discover how to read topographic maps. We tested the hypothesis that the AR sandbox is a more effective tool for teaching topographic maps than the traditional, paper-based approach alone. Students enrolled in an introductory geology course were randomly divided into two groups. The control group (N = 82) completed the paper-based topographic maps laboratory course. The experimental group (N = 94) completed the same laboratory course but also used the AR sandbox. Students spent 15–20 min working on an instructor-guided exercise to explore concepts such as contours, landforms, profiles, and gradients. The following week, all students took a topographic maps assessment. As in previous studies, these data suggest that male students... |
