Article RETRACTED due to bad practices by the authors Validity and Reliability Test Of Gross Motor Development-3 For Childern Aged 4-5 In Indonesia

This study aims to test the validity, reliability and objectivity of the TGMD-3. The population in this study amounted to 45 children with an age range of 4-5 years conducted in three schools. The sampling technique in this study used total sampling so that the entire study population would be the research sample. Data analysis uses empirical validity test using Pearson's simple formula, reliability test using Cronbach's Alpha coefficient and objectivity test using Pearson's simple formula. The results of the empirical validity test obtained a result of 0.504 with an r table of 0.294. So that it is obtained 0.504> 0.294, then the instrument can be said to be valid. The results of the process assessment reliability test obtained a Cronbach's Alpha reliability coefficient of 0.954 with “Excellent” criteria and the product assessment reliability test obtained a Cronbach's Alpha reliability coefficient of 0.895 with “High” criteria. The objectivity test results show that the process assessment conducted by the first examiner and the second examiner has a result of 0.812 with the criteria “High” and the objectivity test results of the product assessment conducted by the first examiner and the second examiner have a result of 0.999 with the criteria “Excellent”. This shows that the TGMD-3 really measures children's performance in accordance with the results achieved, has constancy between assessors and avoids bias. So it can be concluded if the TGMD-3 is proven to be empirically valid, reliable and objective to measure gross motor skills of early childhood with an age range of 4-5 years.
