  • Evaluating Web Resources5 Major CriteriaAccuracyAuthorityObjectivityCurrencyCoverage

    What is your favorite website?

  • AccuracyRationale: http://www.oncolink.org/; https://www.penncancer.org/

    Anyone can publish anything on the Web.Unlike traditional print resources, web resources rarely have editors or fact-checkers.No web standards exist to ensure accuracy.Know the distinction between author and webmaster.


  • Authority Is there an author? Is the page signed?Is the author qualified? An expert?

    Rationale: Its often hard to determine a web pages authorship.Even if a page is signed, qualifications arent generally given. http://inequality.org/Look for a header or footer showing affiliation.Look at the domain. (.edu, .com, .ac.uk, .org., net)http://www.ovaprima.org/index.htm

  • Objectivity View any Web page as you would an infomercial on television. Ask yourself why was this written and for whom? Rationale: http://www.beefnutrition.orgFrequently the goals of the sponsors arent clearly stated.Often the Web serves as a virtual soapbox.Be wary of advertising masked as informationhttp://wesa.fm/2012/10/05/website-aims-bring-objectivity-marcellus-shale-economic-reports

  • CurrencyIs the page dated?Is so, when was the last update? http://www.cmpharm.ucsf.edu/cohen/research/pages/genomics.htmlHow current are the links? Have some expired or moved?Is there a difference between created date and last update?CNN: http://www.cnn.com/

  • CoverageWhat topics are covered?What does this page offer that is not found elsewhere? http://www.iihs.org/laws/cellphonelaws.aspxHow in-depth is the material?Is it all images, or a balance of text and images?Is the information presented cited correctly?http://www.yogakitty.com/
