This diploma thesis is focused on deciduous trees in the teaching of botany at primary school. In the introduction, deciduous trees and their position in curricular documents are characterized. Theoretical-research work further describes selected forms and methods of teaching used in the teaching of deciduous trees, which were found by own observations during practice or by qualitative research by survey conducted in this work. On this basis, a semi-structured interview with three selected science teachers was created. The aim of the survey was to map and compare the teaching of deciduous trees and the collected data, but especially the opinions and attitudes of individual teachers. Of course, each teacher is an individual and the data obtained cannot be perceived as globally valid for all teachers. Only a more in-depth and wider examination would make demonstrating survey results more accurately possible. The aim of the work also was to analyse selected textbooks of science at the 2nd stage of elementary school in terms of the representation of deciduous trees, which are also used by the interviewed teachers. In the practical part, based on the data obtained from the interview, practical activities for teaching of deciduous trees were proposed. The last part of the work consisted of creating a...
