The Validity of A Website GLE 0701.4.3 Make distinctions about the credibility, reliability, consistency, strengths, and limitations of resources, including information gathered from Web sites. 

Website Validity A seemingly innocent web site related to Dr. Martin Luther King looks innocent enough, but the information on the site itself is definitely not. A student who conducts a search for Martin Luther King in Google will generally find this site in the top five results, claiming it is a "valuable resource for students and teachers."  Since research suggests students are most likely to choose results on or near the top of a list of results, many students are likely to click on this site.

The site contains inappropriate content.

How can you prevent yourself from being fooled by invalid sites?

Learning how to read a web address will help you identify its validity. Do you recognize the domain name? The domain name is found after the http:// and www. to the first forward slash /. For example in the URL, jc-schools.net is the domain name. A domain name can sometimes provide clues about the quality of information of a site or tell you what a site is about.

Reading a URL

How to Read a Web Address What is the extension in the domain name? .com and .net are examples of extensions. Extensions are an important part of domain names. You probably know quite a few already. Extensions are intended to show the type of establishment that owns and publishes the domain. Here is a list to look for: COMMON EXTENSIONS .edu       Educational organization (most US universities) .k12       US school site (not all US schools use this) .ac         Academic institution (outside of US) .sch        School site (some schools outside of the US use this) .com       Company (usually .co in the UK) .org        Any organization .gov       Government agency .net        Network .mil        Military institution New extensions to look for are .biz, .name, .pro, .info. All are used for commercial purposes.
