Metric characteristics of the test of misconception about light

Abstract

Misconceptions (naive knowledge) could be observed from the point of view that there is nothing useful and positive in them for further learning. However, they are actually the main foundation for building the right concepts and scientific knowledge. The only possible way to overcome misconceptions is to improve the teaching process and thus learning. The aim of this study was to verify the basic metric characteristics constructed concept test and detect tendencies in the level of representation of misconception in the understanding of the physical properties of light at primary school students. The sample consisted of 306 students of the first, second, third and fourth grade of elementary schools "Avram Mrazović" and "Ivo Lola Ribar" from Sombor and "Ivan Goran Kovačić" from Stanišić. Data collection was carried out by a testing technique. For the purpose of this research, a special test was constructed to check the student's knowledge, understanding, and ability to apply knowledge through questions (tasks) that include teaching content about the physical properties of water. The research results show satisfactory metric characteristics of the test and indicate the expected participants' misconception about the physical properties of light.
