A study compared the advantages and disadvantages of microform for classroom training applications. Three types of factors were considered: 1) student factors, such as material usage patterns, study styles, examination results, and fatigue; 2) instructor factors, such as attitudes and opinions, the role of the instructor, and the need for adjunct reference materials, and 3) administrative factors, such as logistics and the value which came from using microform. Three classes in an Air Force training school used microforms for a 30-hour course, and three control groups used the same material in hardcopy form. Findings showed that the trainees used the microform systems effectively and intensively over a one-week training period. The experimental group did as well as the control group on examinations. Almost three-fourths of the participants said they preferred to use the negative-image fiche for both classroom and home study. Fatugue resulting from microform use was not a pervasive problem.
