Monitoring language laboratory work

Barely six years after the establishment of the first language laboratory at the University of Utah and five years after a similar language lab had been introduced at Ohio State University, E.H. Schneck complained that students who were supposed to stamp time-slips as evidence of their attendance "(got) someone else to stamp a time-slip; or a student might stamp one when entering, leave the laboratory, and come back to stamp it several hours later" (1930:31)
