Pre-instruction: ask students a week before the session what questions they have about library research (in BlackBoard or by way of the faculty member). Use this in the conversation with the faculty member about the learning objectives and to structure the activities.
Post-instruction: ask students & faculty, "Should this session be taught for this course in future semesters?" and "In which other courses should a library research session be taught?"
(This would be to supplement the minute questions of, "What was the most important thing you learned in the library session?" or "What will you do differently in your research process now?" and "What questions do you still have about finding information to support your paper?")
