A Comparison of Two Methods of Teaching an Engineering Slide Rule Course.
Maier, Robert Oscar
The study compated two methods of teaching the use of the log-log slide rule in engineering courses, a straight lecture method or a lecture-laboratory method. The lecture method consisted of two separate hours a week with class discussion and demonstration by the instructor. The lecture-laboratory method comprised one hour of lecture and demonstration and one hour of laboratory work, during which the students solved problems with individual help from the instructor. To test the assumption that the laboratory method would be superior, an experiment was set up for 171 students in two groups. The equality of the two groups was determined by the Cooperative Mathematics Pre-test for College Students and the final examination was considered valid for deciding which method was better. Provision was made for control of three variables, namely, differences (1) in ability between day and night students, (2) in initial ability of the groups, and (3) caused by improved teaching. Seven day and six night classes were tested in such a way that a fall and a spring semester were taught by each method. The same instructor taught one group of 94 by the lecture method and another group of 77 by the lecture-laboratory method. The first group had a final examination score of 62.0; the latter group had a final score of 70.1. The t-test yielded a value of 2.85, a significant difference in favor of the lecture-laboratory method of teaching. (HH)
