The study worked with 20 athletes, three table tennis coaching experts, and two sports education experts. T-Test of mean difference = 0 (vs not = 0): T-Value = -12.61 P-Value = 0.000 Since the p-value (0.000) <0.01, it can be concluded that there is a significant difference between pretest and mean scores posttest score. The mean posttest score was greater than the mean interpretation score. There was an increase in the score of 8.7 or an increase of 32%. Thus the return board tool can increase the ability of forehand spin with an increase of 32% effectiveness.
