Evaluating Internet Resources A reliable site should make clear how it is organized and maintained. At least one page should include development info. When was site last updated? Check out this resource:

Evaluating Internet Resources Where does page originate? Is a single individual as reliable as university, major company, or government agency?  Beware of ~NAME in directory path of URL. Page may be in personal directory. Check the domain. If source is a company, is the page advertising?

Research Ethics: In-Class Exercise Assume you are writing a paper on global warming for an Environmental Engineering Conference. On a scale of 1 (most credible) to 5, rate the following sources in terms of credibility with your audience. (Greenpeace’s URL) (The EPA’s page on global warming)

Evaluating Internet Sources 1.Is the site updated regularly? -- check dates 2.Is the site well designed? 3.Is the writing grammatical and clear? 4.Does the source make any biases absolutely clear? Is its purpose clear? -- check “About” page

What about Wikipedia?Wikipedia A collaboratively produced collection of articles. Name is a conflation of “wiki” and “encyclopedia.” In response to recent criticism, has heightened peer review process. peer review Is a Wikipedia article a credible source of information for your investigation?

Evaluating all Sources of Information 1.Does the information answer important questions for your research? 2.Is the information current? Can you determine the date of publication? 3.Are presented facts and figures from reliable sources? 4.Can you detect any biases in the way that information is presented? Is this really advertising?? 5.Can you determine the author’s credentials and qualifications? 6.Is the publisher/sponsor credible? (for WWW sources, check the domain).
