Evaluating Web Sites It Looks Lovely, But Is It True? designed, compiled by and mostly written by v guarino
The Internet: It’s a big world out there. Since you were a child, adults were selecting books for you. Your parents chose books for you to read, while your teachers chose texts for you to use. Now that you are old enough to visit the internet, you have to be able to make informed choices on your own.
The Big Lie There is one belief we must unlearn as we enter cyberspace. It is erroneous and will cause us to make poor judgments. The mistaken belief is that... All that we see in print is true.
The Internut After all, anyone can post messages. Anyone can create a website. Anyone can pretend to be someone else. Anyone can try to mislead you. As the internet becomes a more common mode of sharing information, and as the number of sites grows exponentially, you will need to distinguish fact from fiction.
Never Fear Armed with the right questions, you can surf the net and find valuable information that, until a few years ago, you could never access! Those questions are based upon a standard set of criteria known as the...
CARS CARS is an acronym for... Credibility, Accuracy, Reasonableness, and Support Checklist for Information Quality
Credibility Credibility merely means that an author of a web site has credentials that prove he or she is knowledgeable in a field. After all, you don’t want information about your health provided by an electrician in Ohio who enjoys reading health guides during his lunch breaks! Thus, when you arrive at a site, you should ask several important questions that will help you assess the credibility of the site.
A Question of Credibility ? Is the author’s name present? What type of extension is at the end of the URL? Is there an “About this site” & is an e-mail address provided? Is there any biographical information listed? Does the author have a degree or job experience in the field he/she is discussing? Is there a tilde (~) in the address or URL? Is the author affiliated with a prominent institution? Does he/she include a bibliography of his/her previous published works? Anonymity should be considered suspicious. A.com extension indicates a commercial site, whereas an edu, gov or org extension indicates an education, government or organization site. An author should be forthcoming with information about himself, his experience, and his affiliations. If any of the information provided seems fraudulent, try to cross-reference his name and check his affiliations. Also, if a tilde appears in his URL, it indicates that the site is a personal page created by an individual, not an institution. In addition, make sure the site is not created to sell a product. Usually, a “commercial” site will contain “com” in its URL. Finally, use good judgment and trust your instincts!
Accuracy merely means that the information offered at a site is correct and supported by other reputable sources. If a site is inaccurate, its intention may be to mislead you. Thus, when you arrive at a site, you should ask several important questions that will help you assess the accuracy of the site. Accuracy
? Does the site contain numerous spelling errors or numerical inaccuracies? Does it include information that is contradicted by other sites? Does it contradict itself? Is the information outdated or obsolete? Are the links functioning? Are they annotated? Has the site been operating properly each time you visited? Is the content meaningful? Does it seem like fact or fiction? A Question of Accuracy You should be leery if a site includes errors. This suggests that the author is a questionable source of information. So too, whenever you find a site that seems like an ambiguous blend of fact and fiction, or includes nonsensical information, quickly move to another site. Also, if a site or its links do not operate properly, you cannot depend on them to provide current data. In fact, you can go to “File” and “Properties” or “Get Info” to find the last date a site was updated! Finally, any website that seems intentionally confusing or distracting should be avoided.
Reasonableness merely means that the information, data, tone, argument and perspective offered at a site are judicious and reasonable. Remember, your goal is to avoid the odd and unreasonable world of the Thus, when you arrive at a site, you should ask several important questions that will help you assess the reasonableness of the site. Reasonableness Internut
? Is the purpose stated clearly? Is a reasonable tone maintained throughout? Does it offer a well-balanced argument that provides various perspectives? Does it include biased views or exaggeration? Are there glaring flaws in the arguments provided? Does the author share extremist views that reveal undue anger or anxiety? Does the author request personal data from the viewer? The sites that should cause you concern are those that espouse prejudicial or slanted views rather than offering a variety of opinions on a given topic. Even position papers must offer differing views and rebuttals. Obviously, exaggeration and misleading information should also cause you to be highly critical of a site. Likewise, if the explanations are rambling and unfocused, or betray extremist views, you should move on to a more reasonable site. Lastly, whenever a site prompts you to provide information about yourself, avoid it! A Question of Reasonableness
Support merely means that the site is sponsored by accredited institutions, and that the author is closely affiliated with major, respected organizations. Another meaning of support is that the points made at the site are supported by evidence. Thus, when you arrive at a site, you should ask several important questions that will help you assess the support of the site. Support
? Are prominent, respected institutions identified as affiliates of the site? Is an abbreviation for a respected institution included in the URL? Does the site offer instructional support materials from those organizations or links to them? Does it contain primary source material and links to supporting documentation? Are the points made proven by sound data from reliable sources? Can you contact the affiliate organizations? A Question of Support Web site authors who are credible will provide information regarding them- selves & their affiliates. If they are trustworthy, they will include links as well methods of contacting those organizations. In fact, an abbreviation for one of those institutions may appear in the address: the URL may even include “edu” or “gov.” For a complete list, visit this comprehensive site. Furthermore, relevant examples, data and proof should be provided in a clear and coherent fashion. The site should clearly indicate whether its intention is to inform, persuade, educate, or entertain the viewer, so that you can be an informed, critical reader.this comprehensive site
In addition to each of these elements (credibility, accuracy, reasonableness, support), a site should be user friendly. Its structure and design should suggest that the author has his viewers’ best interests in mind. Thus, when you evaluate a site, you may want to consider the following: The Final Analysis The SEARCH ENGINE you choose should provide more educational and government sites than commercial sites (commercial sites usually end in “.com” or DOTCOM, an abbreviation for commercial). Avoid engines like Yahoo that bombard you with commercial sites and pop-ups. The site should be easy to navigate. The site should be audience appropriate. The internal & external links should function. The images as well as the pages should load quickly. The visual elements should help, not hinder, the viewer’s understanding. The icons should make sense and the directions should be clear. The helper applications should be easily accessible. The site should include an index and navigation buttons. The site should provide a “Works Cited” or Bibliography.
