THE BELIEFS OF THE PRIMARY SCHOOL TEACHERS ABOUT MATHEMATICS: SCALE ADAPTATION STUDY

This research aims to obtain a measuring tool developed by Purnomo in 2017 that adapts the scale originally called "Teachers' Mathematics-Related Beliefs" to Turkish to determine the beliefs of primary school teachers in mathematics. The original scale consists of a total of 3 dimensions: the nature of mathematics, mathematics teaching and evaluation of learning in mathematics. The author applied AFA, DFA and reliability testing for each dimension separately while developing the scale. Primary school teachers created all participants of the research during the scale development process. The reverse translation technique was used when translating the relevant scale into Turkish. 216 primary school teachers are the sample of the scale adaptation study. AFA was applied to each dimension with the SPSS program to examine the structure validity and factor structure of the scale. DFA was performed with the AMOS program to determine the level of compliance of the factor structure determined by AFA with the data. DFA was performed with the AMOS program to determine the level of compliance of the factor structure determined by AFA with the data. Reliability testing was performed on the entire scale and each subdivision to determine the reliability of the scale. As a result, it was concluded that the scale of the Beliefs of Primary School Teachers in Mathematics, which is adapted to Turkish, is a valid and reliable measurement tool.
