An interactive point pattern analysis web application and teaching exercise

This paper introduces a web-based, interactive point pattern analysis "game" that allows users to generate quickly and repeatedly a point pattern on screen and immediately learn whether the pattern is statistically different from random. It uses two point pattern analysis methods: quadrat analysis (QA) and nearest neighbor analysis (NNA). Studies have shown that gaming approaches, digital tools, and interactive instruction for teaching spatial thinking complement and enhance students' geospatial skills. This game challenges students to achieve randomness, demonstrates the differences between QA and NNA, and easily permits in-class use by running in any web browser.
