CRITICAL EVALUATIONWhy Evaluate What You Find on the Web?
Anyone can put up a Web page about anything
Many pages not kept up-to-date
No quality control most sites not “peer-reviewed”
less trustworthy than scholarly publications
no selection guidelines for search engines
![Page 21: 1hr Research And Thinking](https://reader036.vdocuments.us/reader036/viewer/2022070315/554e3226b4c905f9478b46c5/html5/thumbnails/21.jpg)
Web Evaluation Techniques Scan the perimeter of the page
Can you tell who wrote it ? name of page author organization, institution, agency you recognize
e-mail contact by itself not enough
Credentials for the subject matter ? Look for links to:
“About us” “Philosophy” “Background” “Biography”
Is it recent or current enough ? Look for “last updated” date - usually at bottom
![Page 22: 1hr Research And Thinking](https://reader036.vdocuments.us/reader036/viewer/2022070315/554e3226b4c905f9478b46c5/html5/thumbnails/22.jpg)
Web Evaluation Techniques
Indicators of quality Sources documented
links, footnotes, etc. As detailed as you expect in print publications ?
do the links work ?
Information retyped or forged why not a link to published version instead ?
Links to other resources biased, slanted ?
![Page 23: 1hr Research And Thinking](https://reader036.vdocuments.us/reader036/viewer/2022070315/554e3226b4c905f9478b46c5/html5/thumbnails/23.jpg)
Web Evaluation Techniques
What Do Others Say ?
Search the URL in alexa.com Who links to the site? Who owns the domain?
Type or paste the URL into the basic search box
Traffic for top 100,000 sites
See what links are Similar pages
Look up the page author
![Page 24: 1hr Research And Thinking](https://reader036.vdocuments.us/reader036/viewer/2022070315/554e3226b4c905f9478b46c5/html5/thumbnails/24.jpg)
Web Evaluation Techniques
STEP BACK & ASK: Does it all add up ?
Why was the page put on the Web ?
inform with facts and data? explain, persuade? sell, entice? share, disclose?as a parody or satire?
Is it appropriate for your purpose?

Let’s a Take Look Dihydrogen MonoxideSounds like a very dangerous chemical indeed. It's actually H2O, but if you're not of a scientific mind this site will get you every time.
![Page 26: 1hr Research And Thinking](https://reader036.vdocuments.us/reader036/viewer/2022070315/554e3226b4c905f9478b46c5/html5/thumbnails/26.jpg)
Save the Tree OctopusVery well put together site and perfectly believable.
RYT HospitalWell put together website, linking into a number of other spoof sites, and from a quick view looks entirely bono fide.
The Ova Prima FoundationThis site has scientific 'proof' that the egg came first. Very well done, with todays date, various sections and very academic looking.
![Page 27: 1hr Research And Thinking](https://reader036.vdocuments.us/reader036/viewer/2022070315/554e3226b4c905f9478b46c5/html5/thumbnails/27.jpg)
Fake Sites The Centaur ExcavationsVery well done, with photographs, created in a good academic style with an .edu domain. Actually explaining a hoax, but from a quick look it's easy to be fooled.
Clones R UsProviding information on their 'cloning' operation for human beings. FAQ, price list, testimonials. Quite slick and professionally put together, though the price list is a giveaway.
Save the Guinea WormWell put together site, very credible, but the URL gives the game away.
![Page 28: 1hr Research And Thinking](https://reader036.vdocuments.us/reader036/viewer/2022070315/554e3226b4c905f9478b46c5/html5/thumbnails/28.jpg)
Fake Sites Online Pregnancy TestThis shouldn't really fool people, but I suspect that it does. You may need to try and be scanned twice to confirm that you are actually pregnant.
People for the Ethical Treatment of AlgaeThe title says it all. It's not particularly well done, in that there isn't a great deal of information there, and it's quite a basic site.
Petrol DirectBuy your petrol direct and have it delivered. It sounds like a sensible deal.

Fake Sites Baby cagesInfant confinement specialists since 2001. This is one of those 'it's probably not true... is it?' sites that you can't be absolutely sure about.Dehydrated waterA commercial website selling dehydrated water. Very well put together.
Free electricity projectCampaign for free electricity. Very busy, and while it's well done I think it's a bit too over the top to be entirely believable.
