Comparing the Effectiveness of two Methods of Teaching Agricultural Science to Students in Vocational Agriculture.
Williams, Twyman G., Jr.
The effectiveness of visible recorded feedback responses in teaching scientific theory and principles to vocational agriculture students was studied. Specific objectives were to determine the value of group feedback to the teacher, the difference in learning retention between students with and without feedback, and the difference in efficient use of teaching time between the feedback and traditional methods. Experimental and control groups of 140 students in four California schools were taught teacher-developed lessons in animal physiology and plant cells. Each for 1 week one subject was taught by by traditional methods and the other by the use of the EDEX Communicator which consisted of individual pupil response units and a console which showed individuals and group student response to each question. The experiment applications in different schools were staggered to utilize equipment. A pretest, posttest and a test for retention after 3 months were given. Data were subjected to an analysis of covariance. Results showed that immediate feedback did not improve student learning more than the traditional method, retention was greater by the control group, and teachers and students judged the feedback meter to be efficient in terms of time.
