Development and Testing of an Experimental Polysensory Instructional System for Teaching Electric Arc Welding Processes. Report No. 24. Final Report.
Sergeant, Harold A.
The population of the study consisted of 15 high school industrial arts students, 10 freshman and sophomore college students, and 10 adults. A polysensory, self-pacing instructional system was developed which included (1) pretests and post tests, (2) a general instruction book, (3) equipment to practice arc welding, (4) programed instruction books, (5) loop films for demonstrating arc welding procedure, and (6) self-evaluation devices. Subjects were administered pretests to determine facts and skills possessed before using the system. General directions were given about the use of the system and the subjects proceeded at their own pace and repeated phases of work as often as necessary to produce a weld of quality predetermined as satisfactory by a jury of experts. Analysis of variance was used to test the significance of the differences between the performance of the groups. All subjects acquired levels of knowledge and performance which were predetermined as satisfactory. The average time required to reach this level was 5 hours and 10 minutes, with the high school students using more time than the other groups. Results indicate the practicability of utilizing polysensory instructional systems for learning high level perceptual-motor skills and knowledge. The system should be tested with controlled groups to ascertain the strength of this approach of instruction. (HC)
