Abstract
Designing and teaching a post-secondary elective Liberal Education course in “Puzzles and Problems” prompts a veteran mathematics professor to re-examine the roles of student and instructor in a university classroom. As students became authentically engaged in collaborative and cooperative development of problem-solving skills, and the classroom environment shifted from teacher-centric to learner-centric, the role of the “teacher” changed radically to a new teacher-learner paradigm, reflecting the emerging 21st century learning environment as it affects both teachers and students.
