When I started teaching library instruction classes, I stuck to the ubiquitous CRAAP model for evaluating resources. Then I learned about BEAM and switched to that acronym for a while. Then I discovered the Edited/Peer-Review/Self-Published x Static/Syndicated/Dynamic grid and kept that discussion alive for as long as I could. Now I use them all (sometimes in very quick succession) and try to convey the more essential idea: it’s your job as the student-writer to tell me why this supports your argument. By placing the ball in their court, the game suddenly becomes interesting.
