Many professors at universities routinely quizzed their students too, although not as commonly as faculty at smaller colleges did. [In 1910]…a questionnaire of University of Chicago faculty revealed that 25 of 122 replying professors gave some kind of quiz each day; 31 gave them each week, and 10 others did so every other week. The following year, in 1911, a survey of 188 economics professors around the country showed that 171 of them employed “oral quizzes” in class; only 60 of them used written tests. Surveying undergraduates alongside faculty, the 1910 University of Chicago survey found that four of five students favored written tests over oral ones.
