Air Force Training Program EXECUTIVE SUMMARY An Air Force introductory course in electronics uses a personalized system of instruction whereby each student views a videotaped lecture and then is given a programmed instruction text. The students work with the text until they have completed the training and passed the test. The pace at which the students complete the course varies and the faster students wait until the others complete before the entire group proceeds further. An alternative system, whereby students viewed the same video-taped lecture and then guided by computer-assisted instruction in place of the programmed text, was proposed. It is the goal of the institute to analyze and compare the efficiencies of both the methods …show more content…

To compare the proposed and the current methods of instruction, an entering class of 122 students was assigned randomly to one of the two groups of 61 students each using either of the methods. The completion time in hours was taken for each student in the study. The objective is to find the difference in the population means of the two training methods; to identify the most effective method of instruction and to make a final decision on the training program to be used in the future. STATISTICAL ANALYSIS As an alternative to the current training method, a new computer-assisted method was proposed. To evaluate the effectiveness of this method, a class of 122 students was assigned randomly to one of the training methods therefore forming two groups of 61 each. The course completion time taken (in hours) by the students, of both the groups were collected. Descriptive summaries for the completion times of both the methods were obtained using MS Excel tool and the measures of central tendency and variability were hence found so that the data could be understood better. This study involves two populations: a population of students using the current training method and a population of students using the proposed computer-assisted training method. In terms of time required to complete the training program, the population means are as follows: µ1 = the mean course completion time for students using the current training method µ2 = the mean course completion time for
