Teaching Introductory Physics Courses to Freshmen and Sophomores at Addis Ababa University

In this talk, I will share my experience as a teacher offering introductory courses in physics to freshmen and sophomores. The period I have been offering these courses spans three distinct generations of students: (i) students before 1974, (ii) students within the period 1974 - 1991 and (iii) students after 1991. The quality, capacity and confidence of the students in these three generations of the period are, generally, of different kind. I will try to explain my observation in this context.
