All excellent questions Adriana. We all started feeling the same, "lost in space", but hang in there and keep asking questions. If you are interested, I'd be more than happy to explain how I am using Wikieductor this semester in my academic writing and qualitative research I courses. I bet if you post a question to the Wikieducator Group you'd receive additional examples as well.
Can I take a look at your academic writing and qualitative research materials, Ben? Would you please e-mail me the links?
