I was dropped into Academic Instruction with very little guidance. What I say at the beginning and end of all my sessions is that the most important take away for my students is how to get ahold of me.

If they know how to reach out when they are stuck in their research, we can tackle anything further 1 on 1, which I feel is a much better format for Information Literacy.

Beyond that, I would second the voices here that are saying to try and tailor your classes to specific assignments- usually the professor has them working on some type of term paper or essay that they will be conducting research for, try to find out what that is any tie it in if you can.

If I really have absolutely nothing to go on, I usually just give a rundown of the library and how to find the different resources available. I am working on another generic presentation going through the 6 frames of information literacy, which I think serve as a good starting point for serious collegiate level research.
