During the fall quarter of 1948 examinations in the introductory Psychology course at Iowa State College were first administered by slide projection. Results of this procedure were considered satisfactory and this method of administration has been continued. The primary reason for utilizing this method was to maintain the security of the examination material. Test slides were prepared in the departmental office, lessening the possibility of students obtaining tests prior to examination date. In addition, all test items were thus subject to independent use, further decreasing opportunities of procuring information as to examination content. Secondary reasons for the procedure were: (1) the assembling of a library of readily selected items; (2) time economy both as regards selection of test content and the actual time spent in administering the examination; (3) equivalent instructions and uniform conditions for a greater number of students; and (4) economical selection of items of varying levels of total-score contribution as determined by item analysis. The purpose of this paper is to describe the required equipment, to outline the procedure followed and to present an analysis and criticism of results obtained.
