Knowing what type of information is appropriate for particular purposes, knowing how to find such information easily, and evaluating information may be called information literacy, digital literacy, media literacy, or techno-literacy. Educators should feel comfortable searching and critically evaluating information found on the Internet before trying to teach these important skills to students. Educators can practice critical evaluation of Internet sources by conducting searches on topics with which they are familiar. Search strategies should include keyword list formulation and Boolean combinations. Using one of the evaluation checklists reviewed in this digest, teachers should be able to evaluate sites critically, and to examine the technical aspects of the site, the authority of the writer, and the validity of the writer's content. At the end of the evaluation, teachers should ask the following questions: whether the site provides the information they need to solve their information problem; and if it does not, how the process could be varied to obtain the needed results. Self-assessment at the end of the information seeking process is a higher-order thinking skill that students and teachers should understand and apply. Critical evaluation of information can be applied to all information sources including World Wide Web sites. This ERIC digest lists what are the important aspects of evaluation for educators; and what are the important aspects of teaching Web site evaluation to students. Includes an annotated bibliography of evaluation checklists. (JMK)
