How do I do action research?

I'm now looking for a guide / process to complete my action research process.  I haven't been able to access the Costello reading on action research, however, I read the Saul & Launius article from the suggested readings for Week 7.  Interesting reading, but is more of a case for and about action research, as opposed to a system for carrying out the process.  

I need a step by step guide for my research.  Finding one (most likely through accessing the Costello reading) is the next step in my project.
