Effects of Thinking Style and Spatial Ability on Anchoring Behavior in Geographic Information Systems

Abstract

The authors propose an instructional use for Google Earth (a GIS application) as an anchoring tool for knowledge integration. Google Earth can be used to support student explorations of world geography based on Wikipedia articles on earth science and history topics. We asked 66 Taiwanese high-school freshmen to make place marks with explanatory notes and summaries (known as anchors) to serve as geographic references; they used anchors that were predefined by their teacher for subsequent geographic searches. Our investigation focused on the processes used to create anchors, how the students used anchors to perform search tasks, and the roles of thinking style and spatial ability on learning processes and performance. The 671 generated anchors were categorized as direct, indirect, symbolic, temporal, spatial, and challenging. According to our results, students with legislative thinking style tendencies created the largest number of anchors but rarely used them for subsequent search tasks; executive-style students tended to make symbolic and temporal spatial geographic references and regularly used the teacher-created anchors and the anchors created by judicial-style students were evenly distributed across all categories. In addition, low-spatial ability students tended to create direct
