Projection Wizard is an interesting tool developed by Bojan Šavrič at Oregon State University. The purpose of Projection Wizard is to help cartographers select the best map projections for their projects.
To use the Projection Wizard select a distortion property from a menu appearing to the left of the map. Then use the highlighting tool to select the portion of the map that your project focuses on. After you make your map and menu choices you'll be shown a list of the projections that are appropriate for your project.
Applications for Education
Projection Wizard is a more advanced tool than most high school geography courses would need. That said, I would use the Projection Wizard to have students discuss the flaws of various map projections. We'd also talk about why a particular type of projection is better than another for different types of projects.
