Bioluminiscent Organisms as Didactic Theme
Ševicová, Michaela ; Hanel, Lubomír (advisor) ; Andreska, Jan (referee)
The primary research question of this thesis is bioluminescence of living beings and the extent to which it is represented and explained in a selection of middle school textbooks. The theoretical part of the thesis establishes general facts about bioluminescence itself, methods for teaching and gradual study of this topic in the distant past, as well as the importance of bioluminescence and its potential for use in today's world. In addition, this part includes a summary of the various means and motives of bioluminescence in select (model) groups of organisms (bacteria, fungi, algae, invertebrate, vertebrate). The didactically oriented part of the thesis involves an analysis of select textbooks that are frequently used Czech middle and grammar schools. The thesis also includes questionary-based research, involving the students in the examined school years and aimed at assessing their knowledge about bioluminescence in living organisms. A video and a worksheet with practice questions was also prepared as part of the research. KEYWORDS bioluminescence, luminescence, luciferin, luciferase, bioluminescent organisms
Euglenids (Excavata: Euglenophyta): Important Species
Bryxová, Tereza ; Říhová, Dagmar (advisor) ; Hanel, Lubomír (referee)
This bachelor thesis focuses on a detailed description of euglenids (Excavata: Euglenozoa), and selected important species from the class Euglenophyta. Euglenids are unicellular mostly free-living flagellates. Their most closely related protozoans are those from the group called Kinetoplastida. Members of Euglenophyta have specific and unique cell structure. A specific organelle, the stigma (also called eye spot), formed by a large number of pigment granules, helps them to perceive the direction from which light comes. An important part of the cell are also plastids, which cause different colouration of euglenids, and thus also colour of freshwater bodies in which they occur. Mobile stages of euglenids possess two flagella (sometimes only one flagellum is present - e.g. genus Euglena) which are anchored in small cavity called ampula. The surface of the flagellum is covered with fine hairs, mastigonemes. The thesis closely focuses on three euglenid species. Euglena viridis is characterized by its green colour and forms characteristic green clusters visible on the water surface of water bodies. Euglena gracilis is of great importance as a potential source in biotechnological use. It is one of the future sources of biofuels or healthy bioproducts. The last closely described model representative is...
Possibilities of Practical Care for Endangered Species of Animals as Didactic Topic
Kremrová, Johana ; Hanel, Lubomír (advisor) ; Andreska, Jan (referee)
This thesis deals with the possibilities of practical care for endangered species and its possible usage as a teaching material in school. The aim of the paper is to find out what knowledge students have on the topic of endangered animals, to compare this knowledge across three types of schools and to find out how well is this topic anchored in educational programs. The work is divided into two parts - theoretical and practical. The theoretical part uses mainly analytical methods and comparison. These methods were used to summarize the main laws on the protection of endangered species in history and today, ways to protect nature and endangered species in our country and abroad, the most common types of injuries in individual animal classes and for the operation of rescue stations. In the practical part, a questionnaire was used in three types of schools. The survey showed that the students of the business academy have the best knowledge about the care of endangered animal species, while the worst results were from students at the lower level of the eight-year grammar school. The results of the questionnaire conclude that this topic is not receiving sufficient attention in schools, which is confirmed by the very small involvement of animal protection in the framework of educational programs....
Educational Activities for Lower and Upper Grammar School Focused on the Grey Partridge
Klapalová, Nora ; Andreska, Jan (advisor) ; Hanel, Lubomír (referee)
This diploma thesis deals with the creation of a clearly arranged calendar which summarizes basic information about the occurrence, breeding and hunting of partridges (Perdix perdix) in the years 1927 to 1960. This calendar was created on the basis of the research of archive years of the magazine Stráž myslivosti which changed its name to Myslivost in 1953. The research period starts with the year 1927 when the partridge population was abundant in the Czechoslovak Republic, and continues until 1960. By this time, the partridge population had undergone a number of changes. The most significant one was the considerable decrease in the number of individuals. The first reason of the large decline in partridges were the severe frosts in 1929 and then also in 1940 and 1941. Since that year, hunters have been trying to increase the number of partridges artificially. On the one hand by catching and releasing them, or by artificial breeding of partridge chickens. At the end of the 1940s, the population increased to half the number of pre-war occurrences. In the 1950s, however, the partridge population declined again. This decline is mainly due to the transformation of the natural agricultural landscape into a cultural landscape and the infrastructure development. Based on the calendar a total of ten...
The Knowledge and Attitudes of High School Students as Future Car Drivers of Vehicles about Collisions with Large Mammals in the Czech Republic
Tábořík, Lukáš ; Andreska, Jan (advisor) ; Hanel, Lubomír (referee)
The diploma thesis deals with the knowledge and attitudes of secondary school students as future drivers towards motor vehicle collisions with larger mammals in the Czech Republic. Collisions with forest wildlife is topical and important, both for nature and for the safety of future and current drivers. Paying attention to this issue in the teaching of science, biology or health education is considered by the author to be essential for the future safety of students. This thesis examines the knowledge and attitudes of students in two schools. One of these schools are the gymnasium, secondary vocational school and primary school (EDUCAnet) Prague and the other is the gymnasium and secondary vocational school of economics (GaSOŠE) Sedlčany. The research instrument chosen is a questionnaire created by the author for the purpose of this thesis. The results are obtained and interpreted from 192 students. After the evaluation of the questionnaire survey, we know that the students have quite a fair knowledge of the means against running into animals on the road and they are aware of the consequences of high-speed driving on the impacts of a collision with wildlife. Based on the results of the survey, gaps in knowledge, accident prevention and drivers' reactions to imminent danger are identified....
