Resumo: | In the last decades, the use of Item Response Theory (IRT) has been implemented due to the complexity of statistical calculations that allows for in-depth analysis of educational tests, questionnaires and lists of items applied in different areas such as psychometry, sports ranking and pedagogy. Based on this premise, this study aimed to verify the suitability of the KTK motor tasks analyzing the degree of difficulty and discrimination parameters of each motor task. A total of 385 children aged 5 to 14 years participated in the study. The instrument evaluated was the KTK (Körperkoordinationstest für Kinder), consisting of four motor tasks: balance beam, single-pedal jumps, side jumps and platform transposition. Analyzes were conducted from the raw data acquired in each motor task. In order to verify the factor structure of the theoretical matrix underlying the test, an exploratory factor analysis was performed, followed by a confirmatory factor analysis. The difficulty and discrimination parameters of each motor task were analyzed using the gradual response model, based on the Item Response Theory (IRT). The results corroborate the factor structure suggested in the original version of the KTK, presenting only one factor, called motor coordination. The AFC indicators were acceptable, indicating good quality of the model adjusted for the sample. It is concluded that the IRT analysis evidenced differences in the parameters of difficulty and discrimination between the KTK motor tasks, demonstrating the importance of considering a weighting in the creation of normative tables of motor assessments. |

A partir dessa premissa este estudo teve como objetivo verificar a adequabilidade das tarefas motoras do KTK analisando o grau de dificuldade e parâmetro de discriminação de cada tarefa motora. Participaram do estudo 385 crianças de 5 a 14 anos. O instrumento avaliado foi o KTK (Körperkoordinationstest für Kinder), composto por quatro tarefas motoras: trave de equilíbrio, saltos monopedais, saltos laterais e transposição de plataformas. As análises foram conduzidas a partir dos dados brutos adquiridos em cada tarefa motora. A fim de verificar a estrutura fatorial da matriz teórica subjacente ao teste, foi realizada uma análise fatorial exploratória seguida da análise fatorial confirmatória. Os parâmetros de dificuldade e discriminação de cada tarefa motora foram analisados a partir do modelo de resposta gradual, fundamentado na teoria de resposta ao item (TRI). Os resultados corroboram com a estrutura fatorial sugerida na versão original do KTK, apresentando apenas um fator, chamado de coordenação motora. Os indicadores da Análise Fatorial Confirmatória (AFC) foram aceitáveis, indicando boa qualidade do modelo ajustado para a amostra. Conclui-se que a análise de TRI evidenciou diferenças nos parâmetros de dificuldade e de discriminação entre as tarefas motoras do KTK, demonstrando a importância de considerar uma ponderação na criação de tabelas normativas de avaliações motoras.Department of Physical Education - State University of Maringá (UEM), Maringá-PR, Brazil2022-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/RevEducFis/article/view/6084810.4025/jphyseduc.v33i1.3329Journal of Physical Education; Vol 33 No 1 (2022): Journal of Physical Education; e-3329Journal of Physical Education; Vol. 33 Núm. 1 (2022): Journal of Physical Education; e-3329Journal of Physical Education; v. 33 n. 1 (2022): Journal of Physical Education; e-33292448-2455reponame:Journal of Physical Education (Maringá)instname:Universidade Estadual de Maringá (UEM)instacron:UEMporhttps://periodicos.uem.br/ojs/index.php/RevEducFis/article/view/60848/751375153966Copyright (c) 2022 Nazário et al.https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNazário, Patrik FelipeFerreira, LucianaBoth, JorgeVieira, José Luiz Lopes2022-06-26T17:58:55Zoai:periodicos.uem.br/ojs:article/60848Revistahttp://periodicos.uem.br/ojs/index.php/RevEducFis/indexPUBhttps://old.scielo.br/oai/scielo-oai.php||revdef@uem.br2448-24552448-2455opendoar:2022-06-26T17:58:55Journal of Physical Education (Maringá) - Universidade Estadual de Maringá (UEM)false |
