This is a excellent resource for learing and teaching the various types of citation styles.

My overall take is that it is a little advanced for the high school students that I teach however it is necessary to have such a rigorous resource available because writing is a serious subject and good writing does not occur overnight-it takes work. The editing and paper analysis process of the Purdue writing service is highly defined. I am familiar with a similar service at the University of Phoenix, which has been in place for approximately 20 years and is highly recommended by PhDs and doctoral candidates. If I had to make a comparison, I would place the University of Phoenix above Purdue University's writing service.

It is the website I trust when I'm writing my own research citations pages. With two examples per most entries as well as the formula, it helps my students power through their first from scratch citation. It isn't going to make kids love writing citations, but it will give them enough information to do it correctly if they pay close attention to detail. However, you can't just direct them to the site. Teachers really have to show the students how to use the resource.
