Webquests can extend over an entire course, several classes or be integrated into a single lesson.
Example
The learners are discussing the topic of UFOs. They use a webpage of eyewitness accounts to answer true or false statements. They then choose one account to explain to other learners. They finish by writing their own article about UFOs.
In the classroom
Webquests are a useful tool but some teachers are cautious of technology-based resources. Because of this, webquest lessons are often planned with non-technological, emergency activities included.
