Discussing validation of 3D character animation demonstrating Ushiro-Ukemi pedagogical progression

Abstract

This study was designed to verify the evidence of validity, through: 1) literature review about ushiro-ukemi pedagogical progression. 2) An expert performed the movement and it was recorded to develop the animation. 3) Finally, an evaluation of 3D character animations processes by other experts' opinions. 13 experts have evaluated three affirmatives through the Likert scale, and answered one question, also in ordinal scale, about the quality of the animation. The calculated medians for the first, second and third affirmatives were 5, 5 and 5 (fully agree), but, only for the 3rd affirmative about sitting ushiro-ukemi, the median was 4 (agree). The percentage of answers that scored higher than agree varied from 84,6 to 100%. The median of the 3D character animation was very good (4) and the percentage of acceptance was 100% (≥ good). The found definitional evidence of validity for these animations ensured their application in a learning material. © 2011 Springer-Verlag.
