Studijní materiály pro badatelsky orientované vyučování k tématu sinic a řas na středních školách
Introduction of the thesis deals with inquiry-based science learning - from the level of research to its evaluation. The following practical advice summarize information about the possibilities of obtaining natural material for teaching, creating permanent diatom preparations and examples of suitable determination literature for teachers. The main part of this work presents 12 elaborated study materials for research teaching method divided into five phycologically oriented topics: (1) cyanobacterial and algal physiology, (2) biodiversity of standing waters, (3) algae defense mechanisms, (4) cyanobacteria and algae like bioindicators, (5) substances in cyanobacteria and algae and their importance for humans. Individual study materials contain information on the level of research, methodological guidance for teachers with a theoretical basis and introductory questions to motivate students, as well as a recording sheet for students and, in conclusion, own proposed solution for teachers. Another part of this thesis is a comparison of inquiry-based science learning with frontal education, which is done by didactic test.
Floristicko-ekologická studie oblasti Bystřicka se zaměřením na ekologii zelených volvokálních řas
Since 1889 twenty-two different species of colonial algae from the order Volvocales have been found in the Czech Republic according to the available algological literature. In this work the morphology and ecology of these species is described in detail. Besides investigating the literature resources, I performed my own floristic research of twenty ponds near Bystřice u Benešova. Phytoplankton samples from these ponds were taken in spring, summer, and autumn of years 2014 and 2015 using phytoplankton net and at the same time the environmental characteristics such as pH, conductivity, water transparency, temperature, and degree of shading were measured. Cyanobacteria and algae in the samples were identified to the lowest possible taxonomic level and their relative abundance was assessed. The differences in species composition between ponds and between seasons were compared using basic statistical methods and relationship between environmental factors and species composition was studied.
