The Pegasus Librarian spent time with a couple of different freshman writing seminars getting them ready to tackle the research component of their classes. Both times she tried a technique that she'd done once last year when she co-taught with a colleague of mine. It’s kind of like concept mapping… but with an eye toward building searches.
An added benefit of this technique is that it gets the whole class up and moving near the beginning. She says this changes the atmosphere of a morning class full of sceptical freshmen.
