ANALYSIS OF TEST TASKS FOR ASSESSMENT OF GENERAL PEDAGOGICAL COMPETENCE OF TEACHERS IN THE CONDITIONS OF THE POSTGRADUATE PEDAGOGICAL EDUCATION BY MEANS IRT

The article is devoted to the analysis of test tasks designed to assess the general pedagogical competence of teachers in postgraduate pedagogical education, and their main characteristics by means of modern testing theory. Designed tests for the start and final assessment are one of the effective, objective and reliable tools for assessing the level of general pedagogical competence of teachers in the context of postgraduate pedagogical education. During the approbation, significant statistical material was accumulated, the mathematical and statistical processing of which by means of modern IRT testing theory made it possible to determine estimates of latent parameters of subjects and parameters of test tasks by applying classical measurement models. Due to the invariance property of the IRT mathematical apparatus, the performed calculations ensure the objectivity of the assessment of the level of training of each student, which does not depend on the difficulty of the test tasks. This made it possible to correctly compare the test results of teachers who performed test tasks of different difficulty. The estimates of the difficulty of the test items obtained by the algorithm are also invariant with respect to the level of pedagogical training of applicants for education in the tested group. The characteristic curves of the difficulty level of the test tasks and the level of training of the test participants were constructed using the Rush model. The analysis of their mutual arrangement made it possible to identify the ways of further improvement of the test, create parallel tests, form a system of tasks that are most effective for assessing the level of pedagogical training of each applicant for education. When designing the test, it should be borne in mind that the proposed tasks should be different in content, form and complexity, then the designed test will carry more information about the subjects and will be suitable for assessing the level of general pedagogical competence of teachers in postgraduate pedagogical education. The testing of teachers of different specialties made it possible to check the quality of the developed test tasks and to establish the level of general pedagogical competence of the tested teachers in the conditions of postgraduate pedagogical education. Calibrated test items were entered in the bank of tasks on pedagogy and were used in the educational process.
