What Does it Mean to Evaluate a Web Site? Let’s look at the Merriam-Webster Online Dictionary definition for the word evaluate. evaluate When you evaluate a web site, you will decide if it presents accurate, up-to-date, unbiased and informative content. Basically, you will look at it carefully and decide if it is a good web site or not.
How Do You Evaluate a Web Site? Today we are going to look at three main methods of evaluating web sites. The three main methods are: 1. Identify the author. 2. Look for any bias that might be present.bias 3. Check to see if the site has been updated recently.
Identify the Author Who wrote this? Web sites should clearly name the author of the information you are reading. Contact information for the author should be provided. At the bare minimum, an e-mail should be provided. Find out the author’s qualifications. Are they experts in the field, do they have valuable experience, or are they unqualified. Type their name into Google and see what you find out.
Look for Bias Once you can identify the author and their qualifications, ask yourself what the author’s purpose is. Is the author’s goal to educate you about a certain topic, sell you something, or to persuade you to think a certain way. Some web sites are written with an obvious or subtle preference towards a particular idea or opinion. They present only the information that supports their point of view. Be Careful! Look for sites that are free from judgment and are balanced in their presentation of information.
How Can You Identify Bias? Look carefully at the words the author uses. Does the author use words that have a negative connotation? Remember, words are powerful, you can tell a lot about an author by their choice of words. Does the author appeal to your emotions? Do they use information to manipulate your feelings and use that to get you on “their side.” Does the author use force to get you to agree with them? Does the author make their views seem like the “popular” choice?
Tips A web site’s top-level domain name is a clue to the type of information you will find there. The most common top-level domain names are :.com – indicates a commercial business.edu – indicates a school, such as a university.gov – indicates a U.S. government agency.org – indicates a non-profit organization, but be careful because “non-profit” has a broad meaning.
Has the Web Site Been Updated? Look for web sites that have timely information. New information may not be reflected in a web site that has not been recently updated. Look around the home page, usually near the bottom of the screen, for the Last Update information.
