The Effects of Different Methods of Practice on Film-Directed Performances. Final Report.
Montgomery, Margaret Anne Patricia; Weakland, Jean Marie
The effects of various rates of presentation were studied in combination with massed and spaced, concurrent and nonconcurrent, overt and covert practice modes on film-mediated perceptual performance. Selected values of the independent variables were investigated within a 3x3x2 factorial design, and the experimental treatments were randomly ordered and assigned to 180 graduate students. Three experimental films were prepared, each containing 24 identical performances of the criterion task, an unfamiliar knotted figure. The films were photographed simultaneously at different speeds: normal speed and two slow motion speeds, with verbal instructions programed on tape cartridges. This method allowed examination of three levels of massed-spaced practice and concurrent-nonconcurrent practice. A criterion testing period followed the single practice period to evaluate four dependent variables, involving step analysis scores and the number of criterion tasks completed. Using variance analysis and the Duncan New Multiple Range Test, significant F ratios were calculated for the main effect of rate. The slower rates were found to be more effective. The data suggest that further research may reveal significant differences for concurrent-nonconcurrent practice modes and may demonstrate interactions. (TI)
