Anyone can publish to the Web! Use critical viewing skills. Ask these questions.... • Who provided this information? Why? • Is someone trying to sell us a product or point of view? • What kind of site did it come from (com = commercial, gov = government, edu = education, org = nonprofit organization). • How might the source affect the accuracy? Can we believe everything that comes from the government or an educational institution? • What biases are likely held by the providers? • If quotes or data are provided, are they properly referenced? How can we validate the information provided? Can we check the sources? • Does the information represent theory or evidence, fact or fiction, etc.? How do we distinguish between these? • How do the visuals, sound, or animation influence how we interpret the information? Do visuals and text convey the same meaning? Excerpted from: Computers as Mindtools for Schools by David H. Jonassen, (2000).
