Sistema de observación para la evaluación técnica en la danza clásica: ejercicio del plié

Abstract

Classical dance is a rigorous, technical, stylistic, cultural and artistic discipline that requires the study of actions and motor skills. The study presents an ad hoc observation tool composed of a mixed field format system and a system of exhaustive and mutually exclusive categories (E / ME), with the aim of validating it in order to be able to code and evaluate a classical dance exercise, the plie of a ballet barre. The instrument is made up of 5 criteria and a total of 84 categories distributed as follows: 9 for musical accounts, 19 for head / gaze, 33 in lower body, 18 in upper body and 5 in spatial direction. The sample was 10 dancers, eight women and two men, all with a professional level in classical dance. A Data Quality analysis and a Generalizability analysis were performed with the HOISAN and SAGT v1.0 programs. The reliability of the observers was carried out by calculating the correlation coefficients Pearson, Spearman and Kendall s Tau b; and using Cohen s Kappa concordance index and Krippendorf s canonical concordance. The estimated correlations were .99-1.00 for inter and intra-observer reliability, Cohen s Kappa index was between .99 and 1.00 respectively, and canonical agreement between 99.6% and 100%. The results show adequate correlation indices, as well as excellent generalizability results with a relative G and absolute G value of 1.00 in the interobserver and intraobserver agreement, revealing that the observation tool has optimal validity, precision and reliability.
