Seven formats of educational testing were compared for student test preferences and how well each evaluated learning. The formats were: (1) true/false; (2) multiple choice; (3) matching; (4) MDT Multiple Digit Testing, in which a machine scores fill-in-the-blanks; (5) fill-in-the-blanks; (6) short answers; and (7) essay. A total of 1,440 survey questionnaires (the Survey of Student Opinions about Methods of Educational Testing) completed at a Midwestern university by students exposed to the MDT method obtained information about student opinions. The MDT was not as well received as were more familiar tests. Students thought themselves less able as test takers. When the sample was controlled for appropriateness to the class, the MDT compared with fill-in-the-blanks for evaluative power and preference. The machine-scored test is practical for teacher use. Eleven figures are presented, and an appendix includes the survey. (SLD)
