Acquisition of a Psychomotor Skill Using Simulated-Task, Augmented Feedback (Evaluation of a Welding Training Simulator).
Abrams, Macy L.; And Others
The research was conducted to determine if a physically complex, continuous, three-dimensional psychomotor skill could be acquired more efficiently with simulated-task, augmented feedback than with the feedback normally provided by performing the task itself. The specific skill selected for the study was shielded metal arc welding because it is representative of this class of skills. Thirty-six inexperienced welding trainees were gathered: 18 were assigned to an experimental group and alternated their time equally between the simulator and the weld shop; the other 18 were assigned to the control group and received conventional welding practice only. After 12 days of training their performance was evaluated based on visual grading of the vertical and overhead test. The following conclusions were reached: the simulator trainees performed significantly better than the conventionally trained group, and the simulator trainees also used 215 times less electrical energy, less welding material, and spent approximately half as much time in the weld shop. A list of references is included in the document. An analysis of the welding skill development and the analysis of variance tables are appended. (Author/EC)
