Determination of test accessibility levels of the math questions in high school transition exams (2018-2020) according to evaluations of secondary school mathematics teachers

In this study, it was aimed to determine the test accessibility levels of 60 questions (20 questions from each year) of which are included in the mathematics tests in the LGS exams applied in 2018, 2019 and 2020, with the evaluations of secondary school mathematics teachers. The case study model, one of the qualitative research approaches, was used in the research. The sample of the research consisted of 15 secondary school mathematics teachers. Research data were collected with a 4-point Likert type "Test Accessibility and Modification Inventory (TAMI)". The dimensions of "paragraph/question stimulus, question root, images, answer options, page/question layout and morality" within the scope of TEDE for each question were examined. Descriptive analysis was used in the analysis of the data. Accessibility values were obtained according to the dimensions of the questions by performing statistical operations on the quantitative data obtained as a result of the teachers' evaluations, and accessibility levels (not at all accessible, limited access, partially accessible, fully accessible) were determined. As a result of the analysis of the data, in the paragraph/question stimulus dimension of the questions in the 2018 test, 2 questions are partially accessible, 18 questions are fully accessible, 9 questions in the visuals dimension are not accessible at all, 4 questions are partially accessible, 7 questions are fully accessible, and in all other dimensions, all questions are fully accessible. has been found to be. In the 2019 test, it was seen that all questions were fully accessible in all dimensions. In the 2020 test, on the other hand, in the visuals dimension, it was found that 1 question is not accessible at all, 1 question is partially accessible, 18 questions are fully accessible, and in all other dimensions, all questions are fully accessible. Although the accessibility in the images dimension of the 2018 test are low, this situation has been improved in the 2019 and 2020 tests. Considering the tests of three years, it was concluded that the test with the highest test accessibility was the 2019 test.
