Learning Experiment: Determine Effectiveness of Controlling Environmental Distractions at the Student Level.
Sumter, Paul Edward
The purpose of this study was to see if learning could be improved by controlling the environment at the individual student's level. A pretest, post-test, random choice design was chosen to obtain data from over 900 subjects of technical-vocational schools, area community colleges, and high schools of Iowa, with emphasis on grades 11 and 12 and upon technical and scientific subject-matter. An apparatus consisting of a visual shield, an audio-blocking control, and an audio-control system, was developed to control the experimental subject's environment. Mental ability records of high school students were used to group subjects in three categories, while the analysis of variance single class and the t-test were used for grouping the other subjects. The findings indicated that three of the four hypotheses were accepted: (1) Visual control was not effective in increased learning, (2) Audio-visual control using commercial ear pads to block sound was not effective in increasing learning, and (3) No interaction was found between mental ability levels and the types of treatments. The original Ph.D. thesis of which this is a summary was submitted to Iowa State University of Science and Technology. (GR)
