CORRELATION ANALYSIS OF TEST ITEMS IN THE 'TEACHING METHODOLOGY: APPROACHES TO IMPROVING TEST QUALITY

Abstract

The article examines the results of a correlation analysis of the quality of test items designed to assess teachers' knowledge in the «Teaching Methodology» section. During the piloting phase, some test items were found to have low correlation coefficients (r<0.3), indicating weak predictive ability. This suggests that such items had insufficient correlation with overall test performance, which could distort the final assessment of teachers' knowledge. To improve the quality of the testing instrument, additional expert revisions and statistical processing were carried out, allowing for the elimination of weak items and enhancing their diagnostic value. As a result, the main testing phase demonstrated a positive trend in the statistical characteristics of the test items, confirming the effectiveness of the implemented changes. The study highlights the importance of teaching methodology in test development and emphasizes the necessity of thorough statistical analysis before including test items in final assessments. The findings can be useful for professionals in educational assessment, psychometrics, and test development for teachers. The conclusions of this study contribute to improving the teacher qualification assessment system and increasing the objectivity of testing.
