Study of Visual and Auditory Presentation in Dental Lecture and Laboratory Instruction. Final Report.
Allen, William H.; And Others
This study compared the relative effectiveness of an automated teaching machine with instructor presented instruction in graduate dental teaching. The objectives were to: (1) determine the effects of 3 laboratory instructional procedures used in combination with 2 lectures on the acquisition of manual operative skills, the learning of information about the skills, the making of visual discriminations, and the identification of instruments; (2) determine reactions of subjects to the modes of instruction used; (3) analyze costs of instruction, personnel time and administrative factors pertaining to use of automated instructional procedures. Subjects were 100 first-year graduate students at the University of Southern California School of Dentistry assigned randomly to 6 different experimental conditions. Results showed no significant differences in the attainment of objective (1) using mixed conventional and machine procedures, but that groups receiving laboratory and lecture by machine only performed at a significantly lower level. Interviews showed the machine-only group felt it needed more instructor help and that the principal value of the machine-mediated teaching was the step-by-step development of the material. (JS)
