+ Navigation-Research-Evaluation SANKARSINGH,C TECH Research & EvaluationInformation located, now what? Information contained on a website must be evaluated. Relevancy Is the info related to the prob? Does it contribute to the intention of the search? Does it provide explanation? Examples? Alternative perspectives? Credibility

+ Evaluate = Read critically Who provided this information? Does the site author have authority in that field? If the site is published by an organization, do you recognize it? Is it clear when the site was developed and last updated? Is there a bibliography/resource list included? Is the content factual/opinion? Theoretical or evidence-based? Fact or fiction?
