Abstract
This study aimed to examine the impact of a TGMD-3 rater training program on pre-service adapted physical education (APE) teachers’ ability to score fundamental motor skills for children with developmental disabilities (DD). The training program consisted of a description of the TGMD-3 instrument and DD, as well as content focused on skill performance and correct scoring through systematic analysis of 13 FMS via the instrument. Three experts established the standard score through the TGMD-3 performance evaluation of a child with DD. Thirty-nine pre-service APE teachers in the experimental group and 30 pre-service teachers in the control group completed the pre- and post-test process in this study. There were significant impacts on the pre-service teachers’ ability to score the locomotor, ball skill subtests, and total skill scores (p < 0.05) compared to the control group. Specifically, the results of the three locomotor skills (running, horizontal jump, & slide) and three ball skills (two-hand strike, dribble, & kick) significantly improved in scoring accuracy. The results of this study can evidence that a TGMD-3 rater training program for pre-service APE teachers enhances the scoring accuracy of FMS among children with DD.
