Pilot study of a didactic test in physical education

Abstract

The study focuses on the pilot phase of didactic test development in physical education. The knowledge test contains 28 closed questions (one correct and 3 distractors) and is based on the requirements of the Standard for Primary Education. The results of the analysis are presented on two pilot forms of the knowledge test. 162 primary school students in the 9th grade of primary school participated in the pilot testing. A three-parametric 3PL model was used to analyse the IRT (Item Response Theory) to obtain the difficulty, discrimination, and pseudo-guessability values for each item. After eliminating problematic items for version, A and version B of the test, satisfactory fits for the single-factor model were obtained through exploratory factor analysis. Both tested versions show the greatest information gain for students with average ability. Internal consistency was assessed by Cronbach's alpha and iterative item reliability analysis (Cronbach-Mesbach curve). The internal consistency of Cronbach's alpha was 0.835 in the test of version A and 0.755 in the test of version B.
