Evaluating Websites

Have you ever used the CRAAP test?

If you are using a website for research--whether is it being used to get some background information, learn more about a topic, or being used in a paper (if your professor allows)--you want to find GOOD and RELIABLE websites.  You want to evaluate them for credibility and appropriateness.  There are a lot of websites out there that promote misinformation, are not fact-checked, or are just opinion pieces (to note a few examples of unreliable information).  You might read and consider an opinion piece in your personal life, but for the most part it will not be used in the academic sciences. 

Not sure how to evaluate websites to find good information?  Follow the CRAAP test!

The CRAAP test asks you to evaluate sources based on three criteria:

  • Currency--The timeliness of the information (how current is it?)
  • Relevance--The importance of the information for your needs
  • Authority--The source of the information
  • Accuracy--The reliability, truthfulness, and correctness of the information
  • Purpose--the reason the information exists

To learn more about how to use the CRAAP test, such as questions to ask yourself as you encounter websites, see this handout developed by librarians at California State University--Chico.

Web Resources

Physics PhET Simulations (University of Colorado Boulder): A website full of simulation videos on many aspects of physics including introductory topics.

Eric Weisstein's World of Physics (Wolfram Alpha sponsored): This website provides an encyclopedia of physics topics.  The site is sponsored by Wolfram Alpha, a leading company in information related to science and technology.

The Feynman Lectures on Physics (California Institute of Technology): This website contains some of Feynman's lectures including ones dealing with thermodynamics and waves, . Richard Feynman was a famous theoretical physicist.

Thermodynamics: This website teaches basic information about thermodynamics. 

More generally, with great power comes great dEnergy/dt

Finding Reliable Web Resources

One way to find websites that are reliable (can be trusted to have true information) is to use Operators as well as other search tricks.  These operators allow you to tailor your search to retrieve better results.  The image below shows one of the most useful operators as well as another trick to help you search.  Other common operators can be found HERE.

In the image, there is an operator site: You can use this operator to tailor your search to particular types of sites such as educational institutions (edu), organizations (org), or government institutions (gov).  These are three most common types of sites you would find reliable information on. 

The other thing to note below is that the phrase medical terminology is written with quotes around it.  This tells Google that you only want results back that have the phrase medical terminology.  Without those quotes Google may retrieve websites that have the words medical and terminology but not as a phrase.  This allows you to find more relevant information.
