CAJCS Extended Essay Guide: FINDING SOURCES & EVALUATION

Important and relevant information to assist you in writing your Extended Essay.

Advice from the IB on Evaluating Sources (Online, Print, and Multimedia)

The Internet is a tremendous resource for finding information, but you need to use it critically and with care. One important thing to be aware of is that unlike resources found in a library in printed form, those found on the internet may not have been through a review or editing process.

When researching online you should:

  • know appropriate search engines to use
  • not rely exclusively on sources found on the Internet
  • have a clear and focused research question to help you search more directly on the Internet (given the amount of information available it is easy to be overwhelmed!) 
  • critically evaluate the reliability and validity of the information presented on the Internet 
  • keep a detailed record of all references, in accordance with the IB’s minimum requirements, ensuring that the URL of where the source was located is written down correctly. This includes recording the date that the site was accessed. The Researcher's reflection space (RRS) is a good tool for supporting this practice.
The following table contains a series of questions you can apply to determine the reliability and validity of the information you find: on the Internet, or in print or multimedia.
Evaluating Sources - Questions to Ask
Desirable source attribute Questions to consider in order to determine this
Authority
  • Is the author of the information identified?
  • If the author has chosen to remain anonymous, why might this be? Is this significant in terms of your evaluation of the information presented? 
  • Is there enough information available to establish the author’s credibility?
  • Is the author affiliated to an academic institution or credible organization?
  • Is the author qualified to write about the subject?
 Audience appropriate
  • Who is the intended audience?
  • Does the information presented appropriately address the target audience?
  • Is the information relevant to your area of research?
 Reliability and credibility
  • Does the information appear to be valid and well researched? 
  • Can it be supported by evidence?
  • Can the information be verified through other sources?
  • Is there a non-web equivalent of this material that could be used to verify the information?
  • Does the URL (web address) give you any indication of the source of the information?
 Accuracy
  • Is there an indication as to who has responsibility for the accuracy of the information provided? 
  • Do you know if the information has been reviewed?
  • Are there grammatical, spelling or typographical errors? If there are, what does this suggest about the source? 
  • Is there a bibliography?
 Objectivity
  • Is the information fact or opinion?
  • Is the language used free of bias?
  • Is the author’s point of view objective or do they make it clear when they are expressing a personal opinion? 
  • Is it a personal website?
  • Is the author affiliated with any institution or organization which might create a bias in the information?

 Currency

  • Is the information kept up-to-date?
  • Is there any indication of when the information was last updated?
  • Are any links up to date and working?

Watch Out for Content Farms!

content farm is a website that contains very large quantities of content, typically of low quality or aggregated from other sites, generated solely to ensure that it appears high on the list of results returned by a search engine.

When doing research you need to stay away from content farms, since these sites will often consist entirely of plagiarized material of questionable value.  Check out the example below.

What's suspicious about this site?

  • The letter spacing indicates that they have copy-pasted from pdf files, which tends to create extra spaces within words. . This would tend to imply that the material is stolen from online encyclopedias, dubious education business sites, and other commercial sites.
  • The statistics and population data in individual articles is from the mid- to late-1990s - more than fifteen years old.
  • If you try a search on a partial quote from an article, for example, the phrase "the word "Afghan" historically has been used to designate the members of an ethnic group also called the Pashtuns" from the Afghanistan article, you will get the 'echo-chamber' effect:  lots of 'spammy' sites with the exact same quote.
  • The site's plagiarized content is on a commonly searched curriculum topic (countries and cultures), but seems to exist for the owner only as a source of revenue.  Pages feature lots of ads in the most prominent places on each page.
  • And if that's not enough to make you suspicious...the owner of the site, Advamet, Inc., has a 'F' rating from the Better Business Bureau!

IS IT CRAAP?

CRAAP TEST

How to Find Out When a Web Page Was Last Updated

Will there always be a way of finding out when a webpage was last updated?  In a word:  No.  

Unless the website itself includes that information, there is no way of figuring out when a page was last updated that is always guaranteed to work. You may get lucky and find a precise date, but you may also be only able to make an educated guess or find no information at all.

Javascript​ â€‹

With the web page in question open, type or paste the following text into your browser's address bar, replacing whatever is there, and press Enter:

 

 

javascript:alert(document.lastModified)

 

Depending on the browser you are using, the "javascript:" part of the text may disappear when you paste -- simply retype any missing text.  In response, the browser prompts you with the date and time the page was last modified, according to the server that hosts it. This method is not guaranteed to be accurate, especially not in the case of dynamically generated pages. Even if the page in question is a static one, the date may simply be when it was restored from a backup or when its layout was changed, rather than when its content was updated.

 

Wayback Machine

Enter the page's address into the Wayback Machine and look through the list of results.

You can use the results to get a general idea of how recent the content is, although most websites aren't indexed regularly, so you won't be able to get an exact date; also, some websites aren't indexed by the Wayback Machine at all, for a variety of reasons ranging from the site owner requesting its exclusion to the way the site was built.

 

Source Clues

Check the address for the page, as well as the HTML source for it. Depending on how it was built, it may use a date as part of the address for the page itself (http://www.example.com/2015/01/23/page.html) or for other files included in it (http://www.example.com/images/20150123.jpg), or have a date string as part of the code. This date is more likely to be the date the page was created than the date the page was updated, but it can still give you a general idea of the page's age.

 

Context Clues

Look through the page's contents for any clues that might help you place it in a rough timeline. These clues usually come in the form of a reference to a particular date and can range from extremely specific to very vague. For example, the birth of Prince George of Cambridge could be referred to as happening "three days ago," "a few weeks ago," "last month" or "two years ago" -- in all cases, the information helps you roughly date the page, but the level of precision varies.

 

Contacting the Owner

The last resort to find out when a page was last updated is to get in touch with the owner -- most websites include a contact method, usually email or a contact form. You are not guaranteed an answer, however, and the older the website is the lower your chances. The contact method may be out of date, the website may be completely abandoned, or the owner may simply neglect to respond.
