If you are looking for a new way to teach the same old content, hop over to webquest.org to explore the hundreds of lessons offered in their library. We like this site because they not only house a huge collection, but they offer guidelines about creating a proper quest.
As you shop some of the WebQuests, it will become apparent how easily they can be tailored to the needs of different learners. In this fantastic quest on propaganda during WWII, for example, students are prompted to gather information from a range of sites with different reading levels and create their own piece of propaganda. A teacher could easily add new sites or highlight certain sites to match the reading levels of different learners. In addition, materials could be added to make the activity less complex. For instance, template for the poster might become part of the quest (at least for some).
