Abstract
Two investigations were conducted to determine the effectiveness of a bowling aid to bowling instruction at the university level. In the pilot study (1960-61) 58 women students were matched (3 game bowling average) and placed into experimental (with aid) and control (no aid) groups. The training period with aid ran through the first 12 games and the non-training period through the last eight games. The experimental study (1961-62) employed 60 men and women students. The use of the aid differed from the pilot study and the training period lasted for only ten games. In addition, the subjects were separated into two ability groups (beginner and intermediate). In both studies each group was taught by the same instructor.
Analysis of variance techniques were used to evaluate the differences observed. In each investigation the individual differences were highly significant, while between groups, game, and group × game interaction were not significant, with the exception of the pilot study (training period games 1-12), in which a highly significant difference was found between groups.
