Ideas of lower secondary pupils related to the content of the curriculum focused on viruses and the ways of their transmission, expressed through a verbal description and drawing
ZÍKOVÁ, Eva
The aim of this thesis was to investigate the perceptions of primary school pupils about viruses and viral infection, both through verbal description and the use of drawings. A part of the thesis was to create a teaching unit based on critical thinking and working with text to develop pupils' constructs about viral issues. The review of the literature focuses on the definition of viruses and viral infection, and the topic of viruses in curriculum documents is introduced, complemented by an analysis of selected science textbooks. Part of the literature review is devoted to teaching methods, with an emphasis on working with text, as this method was used in the research investigation. The research itself was carried out in two primary schools through a questionnaire survey (in the form of a pretest and a posttest) combined with the implementation of the designed teaching unit. The results were then extended with information obtained from interviews with selected pupils. The results of the questionnaire survey showed that the pupils in the study sample had only a rough idea mainly about viruses and had significant difficulties in describing viral infection. After the implementation of the teaching unit, the pupils achieved better results. The teaching unit helped them better express the characteristics of the virus and the viral infection. Interviews with selected pupils confirmed these results, as it appeared that pupils were already able to describe the course of the viral infection in their own words.
