Secondary school students' misconceptions about organization and function of human body

In the diploma thesis, misconceptions in the curriculum of human biology in the third and fourth grades of four-year grammar schools were ascertained by means of a questionnaire survey. The questionnaire was filled in by 92 pupils who had already gone through the thematic unit of human biology. The questionnaire was focused particularly on the circulatory, excretory and respiratory systems. After evaluating the questionnaire, specific misconceptions were identified, especially in the circulatory system. Based on the identified misconceptions, a methodological material was created, which should help to eliminate them in teaching. In one case, the methodological material was verified in practice at the grammar school and in the other case at the MS Teams through so-called focus groups
