Purdue University's Online Writing Lab, but, as a teacher in the Hoosier state, it is often a go to site for numerous teachers as students work on papers. One would not really consider Purdue, a university known for Veterinary Science, Agriculture and Biology to be stellar in the area of English and citation, but this site is amazing.
The site has a lot of tools for the classroom teacher as well as updated information about style guides and formatting of a paper. It allows for the user to get find up to date information about the different writing styles. The site does not make the citation for you, but it teaches you the steps to make it correctly.
The tab for 7-12 teachers guides users through the writing process. It has many links that relate to different writing topics to help get writers started. It also has an up to date MLA and APA writing style guide to get writers started in the research process. There is also a very handy guide to avoiding plagiarism. I recommend if you are teaching the steps to research, you start kids here. It is a great tool for the actual process of developing ones own works cited page and in text citations. If you teach the steps and train students to do the process on their own, this is the place to start.
In my next post in the Citation series: OSLIS to do citations.
