Abstract

Most of researchers are building and standardization the parallel forms of knowledge tests in the physical education and sport areas by assessing the psychometric characteristics according to the classical measurement theory, which may lead to low equating levels. It directs to use advanced strategy treatment to investigate the internal and external equating, latent structural and psychometric characteristics of the parallel forms of knowledge tests to solve the problems and weaknesses related to parallel forms equating for knowledge test. The study aims to use the Rasch Model under the Modern Measurement Theory and the Confirmatory Factorial Analysis as the advanced strategy treatment. The Health-Related Physical Fitness Knowledge Test used as experimental model in this study, which have two parallel forms and each of them includes 50 items spread over six major dimensions. The study used the descriptive survey approach. Non-probability sample selected by voluntary participation style of youth aged stage, who enrolled in secondary school and university. The results showed the goodness of fit for parallel forms of knowledge test according to Rasch Model and structural equation modeling, which refers to the quality level of the internal and external structural equatingfor both forms of the knowledge tests.
