There are three strategies for critically evaluating information on the Internet: (1) examining initial markers (superficial characteristics of a website that can help make an initial judgment); (2) corroborating information (looking to other trusted sources to verify information); and (3) determining author bias (analyzing the author's intent for a specific agenda). In this article, the author describes how he modeled each strategy for students, using an Internet-connected computer in his classroom attached to an LCD projector, and how he then invited students to work with him as they practiced the strategies together.
