An Experimental Study to Evaluate the Effectiveness of Certain Structured Teaching Materials.
Ehresman, Norman Donald
A random sample of 20 Illinois schools offering vocational agriculture participated in a study to ascertain the relative effectiveness of structured and unstructured printed instructional materials. Half were randomly designated as experimental and the others were control groups. A unit on agricultural cooperatives was taught, and pre and post tests were administered. The experimental variable was a structured source unit. The difference in mean post-test scores did not differ at the .05 level when tested with the "t" test. The reaction of teachers using the structured source unit was favorable. It was believed that the structured unit would be beneficial in saving teacher time and encouraging adoption of new units if adequate assistance in utilizing the material was provided. This Ed.D. thesis was submitted to the University of Illinois. (JM)
