Areal data have been used to good effect in a wide range of sociological research. One of the most persistent problems associated with this type of data, however, is the need to combine data sets with incongruous boundaries. To help address this problem, we introduce a new method for identifying common geographies. We show that identifying common…

Students' difficulties with accurately conceptualizing the relationships among the Earth, Moon, and Sun are well documented. Any teacher who has seen the film "A Private Universe" (Schneps and Sadler 1988) will remember the challenge the interviewees experienced when trying to explain their understanding of this phenomenon. This paper describes a…

This article enquires into the value of "concepts" as a framework for the school curriculum by questioning their contribution towards our responsibilities for thinking about the earth. I take Derrida's deconstructive reading of Plato's Timaeus to show how spaces in meaning can be revealed, and more transgressive ways of knowing invited…

The utilization of Geographical Information Systems (GIS) and geobrowsers (Google Earth) have become increasingly prevalent in the study of genocide. These applications offer teachers and students the opportunity to analyze historical and contemporary genocidal acts from a critical geographic perspective in which the confluence of historical…

Children's cognitive skills change substantially from the time they enter school at about the age of five to when they graduate from high school a dozen years later. Some changes can be attributed to the school curriculum, but others are part of children's developmental evolution as they mature and interact with the world. Rather than reviewing…

This discussion shows that a dynamic model for stimulus generalization based on an elementary diffusion process can reproduce the qualitative properties of spatial orientation in animals, including behavior in mazes. The model provides a behavioristic "reader" for the cognitive maps proposed by E. Tolman (1932). (SLD)

In resource-based learning scenarios, students are often overwhelmed by the complexity of task-relevant knowledge and information. Techniques for the external interactive representation of individual knowledge in graphical format may help them to cope with complex problem situations. Advanced computer-based concept-mapping tools have the potential…

As more archival metadata and archival records become available online, providing effective interfaces to those materials is increasingly important to give users access. This article describes five approaches from the hypertext and visualization research communities which can be used to improve such access: (1) navigating hierarchical structures,…
