In the fall and winter quarters of the school year 1937-38 the gains made by about 200 students were examined to find what correlation existed between success in the physics portions of the course and the two following factors: 1) Intelligence rating, and 2) Previous study of physics. The gains were greatest for the group of highest intelligence and least for that of lowest intelligence. The average gains made by these two groups differed by about 40 per cent. Those who had credit for a year of high school physics made a somewhat greater gain than those who had not previously studied physics. The difference in this case amounted to about 7 per cent. During the winter quarter of the year 1938-39 the gains made by students whose course included 3 hours of lectures and 4 hours of laboratory work per week were compared with those of an equal matched group who had had 3 hours of lectures and 4 hours of experimental demonstration work per week in which the instructor performed the experiments. The gains of the latter group were about 10 per cent greater than those of the former.
