A webquest is an assignment which asks students to use the World Wide Web to learn about and/or synthesize their knowledge a specific topic. A “true” webquest, as originally designed by Bernie Dodge and Tom March, requires synthesis of the new knowledge by accomplishing a “task,” often to solve a hypothetical problem or address a real-world issue.
