Using of Material Didactic Aids in Teaching of Biology on Selected Lower-secondary Schools in Liberec

The thesis focuses on the use of material didactic resources in teaching science at selected schools in Liberec. The thesis is divided into two parts. The first part is a literature survey, which characterizes didactic means in general on the basis of scientific literature. The aim of the thesis was to look more thoroughly at didactic aids, which are the main part of material didactic resources. Furthermore, to focus on the function of the resources in the classroom and to present the options and principles that should be followed when selecting them in order to make their use as effective as possible. The second, practical part, presents the results of observations from a total of 29 lessons which were taught as open lessons, in 3 primary schools in Liberec. The analysis of the collected data provided us with information on how much of the lesson the observed teachers devote to the use of material didactic resources. On the basis of the time load, we got an overview of the preferred resources and could evaluate whether they are traditional (workbook, classical blackboard, textbooks) or modern (Internet services, interactive whiteboards)
