C.R.A,A.P. Test for Evaluating Websites

Check the quality of your websites using these criteria (adapted from QUT Library):
Currency: Timeliness of the information
  • When was the information published, posted or last updated?
  • Is the information current for your topic and field of study? How recent does it have to be? Can older sources work just as well?
Relevance: Importance of the information for your needs
  • Is the information appropriate for a senior secondary course?
  • Is this an adequately in-depth examination or a quick summary of the topic?
  • Who's the intended audience? Is it the general public, a student, a researcher or industry?
  • Is the level of information too basic or too advanced for your needs?
Authority: Source of the information
  • Is the author/authoring body (individual person, or institution, or organisation) established and reputable?
  • Are their qualifications, credentials, expertise, experience, educational background and previous work (if any) relevant and do they add credibility to the source?
  • Has the piece been published by a well-known and respected publisher or organisation?
  • Do references to other sources support the writing ie is a Reference List provided?
Accuracy: Reliability and correctness of the information
  • Where does the information come from, and is it supported by evidence?
  • Does it have a Reference List or Bibliography so you can easily find and verify the sources used?
  • Are there any spelling, grammar, or other typographical errors?
Purpose: Reason the information exists
  • What is the purpose of the information? Why was it written?
  • Does the point of view appear objective, unbiased and impartial?
  • Is the viewpoint of the author's affiliation/ sponsors reflected in the message or content?
  • Does the author acknowledge alternative versions of the issues or facts?

Purpose: Reason the information exists

  • What is the purpose of the information? Why was it written?

Web Searching Techniques

1. Use 'Ctrl F' (Control + Find) to search for particular terms easily in a long document, whether from a website or a database article.
2. Use a Google domain command eg site:edu OR site:gov to limit results to a CERTAIN DOMAIN such as education or government eg biodiesel site:edu
3. Use a Google command to limit results to the MOST RECENT: After you get your results, choose the Google Menu Bar, and choose 'Tools'. Then on the far left, at the drop-down menu next to 'Any Time', you can choose 'Within the last year' (or less, if you prefer), but generally, you can choose 'Custom Range' at the bottom, as often the last 3-4 years would be sufficient for a recent search.

Advantages / Disadvantages of Google Scholar  

How to use Google Books

Google Books can be very frustrating because often much of the book is missing and you are expected to purchase it to read the full content. So after you put in your search term you are interested in (eg biodiesel), and get some results up,  you should then go immediately to the search box (on the left - above 'About this box') undefined 
and type in a particular word or term you are interested in (eg CO2 emissions OR methanol) you should get a number of pages pop up. Choose one that looks useful - you should get some good results this way!
