The Teaching Efficiency of the Film J. W. Shepherd University of Oklahoma WHAT is the teaching effi- ciency of a motion picture film as measured by the re- sults obtained by the teacher in the class room? This is a legitimate question and perhaps one of the first and most fundamental issues met when we begin to talk about the educational film. When the super- intendent employs a teacher, he wants to be assured that she can teach, that is, that the results ob- tained in her class room will reach certain reasonable standards. In a like manner, the careful superin- tendent wants to be assured that there will be definite results ob- tained in the class room before he is willing to sign contracts for mo- tion picture films involving consid- erable sums of money. And, after all, this has been the big issue with all of us. We have raised the ques- tion in our own minds and fre- quently have settled it "can the film teach?" If so, with what effective- ness? If we could show results of a positive nature that the film has teaching power and that it can be measured then a hundred other questions arise at once concerning methods, administration, produc- tion, and other problems. If on the other hand, negative results are ob- tained, many of these issues would cease to have significance. The writer began, series of experiments therefore, in the Un versity of Wisconsin in the fall <j 1919 to determine what seemed 4 him to be the basal fact or facts i connection with the education* film. If we could once get such definite measure of the film's teacq ing power then other problem would follow in more or less log ical order. But should it be detei mined that the film had little teach ing efficiency then these problem would become changed both in thei significance and in the mode c attack. For the study a class of fifty-fou high school pupils was selected in University teacher training higi school. These pupils were divide into three groups as nearly equal a possible on the basis of age, sea grade, scholarship, and intelligenc ratings. This division was made b; the vice principal of the high schoc who took first the three oldest an] best boys, next the three oldest am best girls, and so on through the clasi so that in case one of these three wa absent or his re-action affected ab normally so that his results should b eliminated, the results of the othe two would also be eliminated, thu maintaining as nearly as possible a! equality of group value or ability. The film selected was "Elements o 176
