CONTENT VALIDITY OF THE TEST OF MATHEMATICAL TALENT
CONTENT VALIDITY STUDY OF THE TEST OF MATHEMATICAL TALENT FOR 6th AND 7th GRADE STUDENTS
The Test of Mathematical Talent (TMT) is a test developed to identify 6th and 7th grade students who are gifted in mathematics. During the development process of the test, item properties, reliability and criterion validity were focused on. In this study, the content validity of the test was examined. With the data obtained through expert opinions, the strengths and weaknesses of the test in terms of content validity were tried to be revealed and comments were made on the adequacy of the test. Mathematics teachers and academicians working on mathematics education and mathematics science at the faculties of education of universities and mathematics teachers who were selected through convenient sampling participated in the study. The reliability of the five-point Likert-type scale used as a data collection tool was found to be .72. The data obtained were analyzed in terms of frequency and percentage distribution and interpreted according to content validity ratios based on these data. When we interpreted the data obtained as a result of the study according to the content validity index, it was seen that the test was generally well structured and sufficient in terms of content validity. However, when some subtests were evaluated in terms of content validity, their adequacy was found to be moderate and below the expected value.
