Effects of Systematic Variations of Instructional Variables in a Verified Instructional Program.
Reiser, Robert A.
The variables of practice, incentive, instruction, and feedback were examined to determine which contributed significantly to the effectiveness of an instructional program, which was systematically developed to include the four variables. Two studies were carried out using the Aircraft Instrument Comprehension Program and Test. In the first study the effects of practice and incentive on learner posttest performance were examined, using two levels of each variable in a 2 x 2 factorial design. A second study examined the effects of instruction and feedback using the same design. Results indicated that instruction had a strong effect on learner performance in that scores on the posttest were significantly higher than on the pretest. Practice and incentive had a significant effect on the time required to perform the task. The test scores and statistical analyses are appended. (SA)
