Abstract:

The development and support of mathematical skills in early childhood is important for the child to be able to understand mathematics in the upcoming years and to acquire the knowledge and skills necessary for later school life. The first step for this is to determine the level of children’s early mathematical skills. This study included the development, validity and reliability studies of the Early Mathematical Test (EMAT) in order to evaluate the early mathematical skills of children aged 3-7 years. In this scope, the first application in 8 schools in the province of Ankara 3-7 age group with 650 children, and the standard study in the province of Turkey determined the same age group with 2018 children. The data was obtained by researchers and practitioners who received test training by the application of the scale individually to children. The validity of the test has been used for the validity of the scope, comparison by age and validity based on measurement. Early Mathematical Skills Test (TEMA-3) is used for measurement validity. In the reliability studies, two half-test reliability, the KR-20 ratio calculated for internal consistency and the test-up test reliability have been used. According to material and test statistics, the Early Mathematical Test, which consists of three sub-tests and 105 subjects, is a valid and reliable tool for measuring the early mathematical skills of children aged 3-7 years.
