Testing the influence of newly created learning materials for the fluorescent microscope on students` knowledge
Filipová, Jana ; Janštová, Vanda (advisor) ; Mourek, Jan (referee)
Among students, interest in Science is decreasing, despite the fact that knowledge of Science can be useful in many real life situations, such as medicine, conservation etc. Science education can also simply help to form a positive attitude towards nature. There are many possibilities of increasing students' interest in Science that could increase their motivation to study. Apart from Inquiry Based Education or Prescribed Practical Activities, working with devices used in research practice is one of the possibilities. If a school doesn't own such devices, there is a possibility to borrow them, or to work with them via the Internet. Possibilities of remote access to these devices are subject to research abroad, and this trend is also starting to appear in the Czech Republic. One example of a device that can be borrowed by schools is a fluorescence microscope at the Department of Didactics and Education of Biology, Faculty of Science, Charles University in Prague. In my thesis, I was investigating the influence of the presence or absence of this fluorescence microscope on the knowledge of students. Research was carried out in four different classes at two secondary schools in Prague. Students who took part in this research were from the first year of a four year secondary school or from the third...

Design and testing of students'materials for a field trip to Brdy area
Přibylová, Anna ; Janštová, Vanda (advisor) ; Kroufek, Roman (referee)
The reason why I chose this topic is that field trips (short-term or long-term) have demonstrable effect on students' knowledge, values and attitudes as well as teachers' skills. The objective of this thesis was to prepare a field trip including all needed teaching materials and evaluate it's effect on students' knowledge. Created teaching materials were tested in four classes in two primary school in Příbram and a nearby village. Students from these schools were divided into two groups - experimental and control. The experimental group attended the field trip and the control group got involved in the same program but at school. Both groups completed pretest, teaching, posttest 1 (with a feedback about teaching), posttest 2 and 3. Data collected from this research were evaluated using statistical methods. The results from these methods proved a significant difference of knowledge between groups in posttest 1 and 2. The score of both groups gained in posttest 3 was similar. We can conclude that students of both groups learned new information and their knowledge improved. Nevertheless the field trip had significantly higher effect on students' knowledge than the school lesson. Key words: teaching methods, field trip, students' knowledge, knowledge testing

Development and history of nuclear weapons and their importance today.
KRAFKA, Jiří
The term atom has fascinated the philosophers since Ancient Greece. Since this period the scientists from the whole world have been more and more interested in the atom. They have researched its structure, properties and applicability. The atom has also become the basic element for constructing nuclear weapons. Many states all over the world tried to construct these weapons during the Second World War. In 1945 the United States of America managed to design ones. The Americans used them against the civil inhabitants twice. The weapons were dropped over the Japanese cities of Hiroshima and Nagasaki. Since the year 1945 more than 2 000 nuclear tests have been taken. That is why international contracts which adjust the testing and use of nuclear weapons have emerged. In the theoretical part of my bachelor's thesis on the topic "The development and history of nuclear weapons and their significance for today's world" I deal with the atom, its history and radioactivity. The next part of the bachelor's thesis is dedicated to the development of nuclear weapons in various countries which tried to design a nuclear weapon during the war. Afterwards I described the war use of nuclear weapons against the civil inhabitants in two Japanese cities, Hiroshima and Nagasaki, which lead to the end of the WW II. The aim of the bachelor's thesis was to evaluate possible use of nuclear weapons, alternatively a nuclear war, and to verify and compare students' knowledge of nuclear weapons and their effects. These students involved in the research were the ones studying the programme Population Protection in the bachelor's as well as in the master's study. Within the thesis the following hypotheses were stated: "The knowledge of students of the study programme Population Protection has normal distribution" and "The knowledge of students of master's study will be statistically more prominent than of the ones studying the bachelor's study. To reach defined aims it was necessary to analyse literary and other sources. Next, it was indispensable to create a questionnaire and perform a questionnaire survey. The research ensemble comprised 126 students of the bachelor's study programme and 50 students of the master's study programme. The questionnaire which was presented to these students consisted of 14 questions. It was aimed at finding out the knowledge in the sphere of nuclear weapons and on the basis of the results I compared the knowledge of the students of the bachelor's study programme and the master's one. The students of the programme Population Protection in the master's study proved better knowledge of examined issues than the students of the bachelor's study. However, the students showed unsatisfactory knowledge in some of the questions. Especially in the second one, only 33 % of the respondents knew what the name of nuclear programme in Germany was. The next problematic question was the one number 13, in view of the fact that 53 % of the students know that the most nuclear tests were performed by USA and 47 % of the students thought that it was the Soviet Union which carried out the most tests. The question number 4 was correctly answered by 55 % of the students. The question was: "What was the name of the first nuclear bomb?". The sixth question concerning the year of testing this first bomb was also correctly answered by only 55 % of the students. On the other hand, the students proved the best knowledge when responding to the seventh and eighth question. When answering the question number 7, 96% of the students know that after the explosion of a nuclear bomb a mushrooms cloud is formed. The gained data from the questionnaires were statistically processed. Subsequently, the given hypotheses were confirmed, the knowledge of students of the study programme Population Protection has normal distribution and the knowledge of students of master's study will be statistically more prominent than of the ones studying the bachelor's study.
