"Shorn of all subtlety and led naked out of the protective fold of educational research literature, there comes a sheepish little fact: lectures don’t work nearly as well as many of us would like to think." A quote by George Cobb (1947 - 2020) from his 1992 paper "Teaching Statistics," in Heeding the Call for Change: Suggestions for Curricular Action, ed. Lynn Steen, MAA Notes Number 22, 3-43. The quote is a well-phrased reminder that listening to lectures is not an effective way for students to learn.
