Jose Bowen, president of Goucher College and author of the book _Teaching Naked_, is starting a 5-part series on liberal arts education as the "degree of the future". In part one, I'd note the implied difference between "critical" and "creative" thinking.
Interesting to connect the job of helping students prepare for end-of-semester assignments or exams with the goal of bringing a sense of closure to your course.
There's a survey instrument attached which you can use to have students reflect and report on how they study for exams. They can then ask themselves if their approach is working - or you could tally the data and tell them which approaches are being used by the students getting the best grades.
Some interesting examples here of questions you can ask students to help cement the major concepts of your courses. (Some of these would fit in nicely as part of your personal questions in the course evaluation system!)
