Lower-secondary students' drawings as a tool for finding their knowledge about external and internal constitution of fish body
VAŠKOVÁ, Iveta
The aim of the diploma thesis is to analyse drawings of internal and external constitution of fish bodycreated bylower secondary students atselected schools in South Bohemia. A total number of 127 respondents from four schools and one grammar school were involved in the research. The questionnaire with three parts was used to collect data. First part was focused on demographic data about the respondent. Second part included a task for students to draw the external structure of the fish's body, while paying attention to the correct location of all fins. Third part of questionnaire contained pre-printed silhouette of a fish (carp), where students tried to correctly sketch pre-selected organs (heart, brain, stomach, intestines, liver, kidney, gas bladder, gills and lateral line organ). There was found in the analysis of the second part of questionnaire that the carp was the most frequently sketchedfish species. Most students had difficulty with drawing correct number of fins and placing them correctly. In third part of questionnaire, brain was the most often drew and correctly located organ. On the other hand, liver was the least drawn and kidney the most incorrectly drawn organ. Activities which could help with teaching this topic in biology lessons were designed based on the collected data. Three selected activities were introduced to lower secondary school teachers in order to get their feedback. Based on this information and pilot testing of two activities the methodological recommendations were written and some activities were slightly modified. The contribution of this diploma thesis can be considered in the practical use of theoretical knowledge of this topic and also activities which can be used by biology teachers at lower-secondary level. The results of the diploma thesismay be useful for the professional community as well as general public. They can become the basis not only for improving teaching this topic, but also for follow-up research using drawing as a tool for investigating the level of students' knowledge. Key words: children's drawing, externalconstitution of fish body, internal constitution of fish body, teaching activities, textbook.
