Effect of Specific and Variable Practice on Learning an Archery Target Shot

Jeff E. Goodwin and Holly A. Jones, The Citadel, Charleston, SC

The purpose of this investigation was to examine the effect of supplementing specific practice with variable practice in acquisition on retention and transfer of an archery target shot in a standard physical education instructional setting. Forty-six undergraduate students from four archery courses at The Citadel participated in the investigation. At the beginning of the investigation, participants were randomly assigned to one of three practice conditions. During the first week, participants were instructed to use proper shooting techniques and told they would shoot from various distances according to a predetermined schedule. The second week consisted of a pretest in which participants performed a total of 20 trials from 6.10 m. The acquisition phase covered four weeks. Participants in the Specific condition practiced a total of 30 acquisition trials from 9.14 m. Participants in the Specific + Specific condition practiced a total of 60 acquisition trials from 9.14 m. Participants in the Specific + Variable condition practiced a total of 30 acquisition trials with 10 trials performed from 6.10 m, 9.14 m, and 12.19 m with no more than one distance practiced two times in succession. During the seventh week, a retention test was administered and consisted of participants performing a total of 20 trials from 9.14 m. Afterward, a transfer test was administered and consisted of participants performing a total of 20 trials from 13.72 m. Mean radial error (MRE), group centroid radial error (GRE), and bivariate variable error (BVE), for trials in the pretest phase, retention phase, and transfer phase were calculated into trial blocks of 10 trials. Trials in the pretest phase were analyzed in an analysis of variance (ANOVA) and revealed no significant differences between practice conditions. Trials in the retention phase were analyzed in a 3 x 2 (Practice Condition x Trial Block) factorial ANOVA with repeated measures on the last factor and revealed no significant differences between practice conditions. Trials in the transfer phase were analyzed in a factorial ANOVA with repeated measures on the last factor and revealed the Specific + Variable condition performed with significantly smaller MRE and GRE than the Specific and Specific + Specific conditions. The Specific + Variable condition also performed with significantly smaller BVE than the Specific condition. Retention and transfer results in this investigation support other investigations that have shown supplementing specific practice with variable practice is as good as, and sometimes significantly better than, specific practice.
