Virtual Field Trips
One way to build students' prior knowledge before reading is to go on a field trip - or a virtual field trip. Exploring a topic through photographs and video clips on the Web can be a quick way to bring all of your students to a more equal level of prior knowledge before you read. This site shows a few examples. You can build your own virtual field trips using the "Scrapbook" function of Filamentality.
