It has been hypothesized that the degree of learning, other things being equal, is a simple function of the amount of time during which the pupil engages actively in learning. This hypothesis was tested with forty-eight students in an introductory psychology course. Classroom examinations were used to indicate amount learned; intelligence tests were used to indicate learning ability, and hours of

When learning ability was controlled, statistically, the correlation between amount learned and learning time was statistically significant, r = .30, a result which provides support for the original hypothesis. Considering the attenuating effect of indicants, it was concluded that learning time is a highly important variable which should be taken into account in investigations of classroom learning.
