B. A., Yeah, I've often commented that if content is worthwhile, valuable and contributes to learning, it ought to be included in the regular curriculum. I do like the prospect of student-selected demonstration of learning. Methods I regularly use to achieve that is a (graded) project or paper, with parameters defined, but allows the student to convey their creativity along with grasp of the material. Another version of independent demonstration of learning is on mid-term and final exams. Here, I'll give an essay assignment that allows the student to demonstrate their understanding in their own way, in their own words. But even this is limited towards impact on the grade (i.e., worth UP TO 5 points out of, say, 120 points). Barry Westling
