Some other STEM courses are evaluated in very different ways. ENGR 100, 110, and TCHNCLCM 300, while labeled as lectures, are quite different in practice. ENGR 100 is a project-based introduction to engineering, ENGR 110 a one credit seminar introducing engineering education and careers, and TCHNCLCM 300 is a writing-based course often structured around group work. Biology 118 is a course on AIDS for non-scientists. None of these courses used timed examinations as important evaluative elements.
