Design of new laboratory exercises with gigabit passive optical network
Chlápek, Jan ; Škorpil, Vladislav (referee) ; Horváth, Tomáš (advisor)
The diploma thesis is focused on design of new laboratory exercises on the topic of gigabit passive optical networks. The theoretical analysis is devoted to acquaintance with basic problematics of PON and analysis of individual PON standards. Special attention, besides GPON, XG-PON and EPON standards, is devoted to security issues in PON. The goal of practical section of the thesis is the design of four laboratory exercises. Two exercises are focused on configuring GPON and XG-PON networks in a console environment with the help of exemplary console commands. The goal of the third exercise is to hook up and configure an EPON network using web configuration interface. The fourth exercise is designed for a realization of DoS attack against a fully functioning laboratory GPON network. The objective is to jam the upstream communication bandwidth with laser transmission causing a desynchronization between active network elements.

Measurement in Electrical Engineering – Digital Learning Materials
Ondráčková, Michaela ; Langerová, Petra (referee) ; Ellederová, Eva (advisor)
Cílem bakalářské práce je poskytnout podklady pro tvorbu digitálních učebních materiálů pro předmět „Měření v elektrotechnice“. Práce je zaměřena na samotný koncept digitálních učebních materiálů a na metodologii tvorby digitálních učebních materiálů. Dále se práce zabývá studijními požadavky samotného předmětu („Měření v elektrotechnice“), nezbytnými teoretickými východisky pro tvorbu didaktických textů a také požadavky na návrh. Navíc práce obsahuje dva návrhy digitálního učebního materiálu, prezentaci a pracovní list.

Commented Translation: Measurements in Electrotechnics and Audiotechnics
Šustrová, Pavlína ; Krhutová, Milena (referee) ; Kotásek, Miroslav (advisor)
Předmětem této práce je komentovaný překlad instruktá- žního textu používaného v univerzitních kurzech Měření v elektrotechnice a Měření v audiotechnice. Překlad byl vytvořen pro potřeby budoucích zahraničních studentů navštěvujících uvedené kurzy. Komentář uvádí důvody motivace k provedení překladu, překladatelské teorie a pohledy aplikované během překladu, potíže ke kterým v průběhu došlo a jejich individuální řešení, včetně konkrétních příkladů, a stručnou lingvistickou analýzu textu. Kromě samotného překladu tato práce představuje koncept slovníčků které by doprovázely každý laboratorní návod v textu. Finální verze překladu je připravena k posouzení, zda může být použita jako oficiální studijní materiál.

Measurement of corrosion resistance of the material
ŠVARCOVÁ, Denisa
Aim of the bachelor thesis is bringing the concept of corrosion closer to second grade pupils of elementary school. In the theoretical part of the work is summary of the concept of corrosion, types of corrosion and protection against corrosion. In the practical part is performed measurement of corrosion resistance of martensitic steel depending on temperature and time. The didactic part of the work consists of laboratory exercises, where the pupils try to measure the corrosion resistance of the material in different environments, and of worksheet, which is used to repetition and to complete of the concept corrosion.

Distance practical teaching and learning
Zdobinská, Helena ; Janštová, Vanda (advisor) ; Jedličková, Tereza (referee)
This diploma thesis describes practical activities and related topics during forced distant education due to COVID-19 pandemic. In the theoretical part of thesis, the distant education is defined. I also described some of its features, which includes absence of physical contact, use of communication platforms, synchrony and asynchrony form of lesson, need for some degree of independence and digital competence. Anonymous questionnaires were made to collect the data from students and their science subjects' teachers (biology, chemistry, and physics). The questions were with free answers, closed answers with choices or scale values. Respondents consisted of 543 students and 24 teachers from Prague and Central Bohemian Region. The answers were categorized and frequencies calculated. The values of numeric answers such as mean, median, minimum and maximum were measured. The relationship between data was analysed by Pearson's chi squared test of independence. This study shows that teachers used practical activities such as experiments, observation or creating something less in distance lessons, compared to their face to face lessons. On the contrary tasks based on text work were used more often. The analysis showed that students preferred tasks containing creating something. Most teachers taught in both...

Role of Experiments in Chemical Education at Waldorf Lyceum Compared to "Ordinary" Gymnasium in the Czech Republic
Studničková, Zuzana ; Šmejkal, Petr (advisor) ; Stratilová Urválková, Eva (referee)
4 Abstract This bachelor thesis examines the role of experiments in Chemistry lessons at Waldorf schools and roughly compares the approach towards their implementation into lessons at Waldorf schools and selected secondary schools (gymnasia) in the Czech Republic. The first part is dedicated to the description of Waldorf school specifics. The second part gives results of a general survey focused on the ways of use and frequency of experiments at selected secondary schools in the Czech Republic. Results of this survey and visits to laboratory practicals at one high school were confronted and discussed in contrast with results of inspections of classes at two Waldorf schools; Waldorf Lyceum in Prague and Primary and Secondary Waldorf School in Semily. Approaches to experiments at both types of schools are compared and arguments for and against are given. On the whole we can say that Waldorf schools take experiments (demonstrations) as an integral part of every Chemistry lesson and are essential for Chemistry education. However laboratory practicals are rare and the amount of information in lessons is smaller than at ordinary secondary schools observed. On the contrary, at ordinary secondary schools, demonstrations are less common and very often experiments are not included in Chemistry lessons, but separated...

Plant Alkaloids - Integration in the Curriculum of Thematic Area "Plant Biology" for Grammar School
Větrovská, Eva ; Teodoridis, Vasilis (advisor) ; Odcházelová, Tereza (referee)
The presented master thesis is focused on an integration of plant alkaloids' curriculum into education process at eight-year grammar schools or their equivalent at primary and secondary schools. The aims of the thesis are to provide a basic data about plant alkaloids, to specify an integration of the plant alkaloids into the curricular documents and to select specific and suitable methods for teaching of the alkaloid topic at schools. These teaching methods were practically verified at the Karel Čapek's Grammar School at Dobříš by using author's proposals of the school lesson, the project teaching and laboratory exercises. In the terms of benefits for students, it has been verified that the teaching of plant alkaloids using the teaching project and the laboratory exercises, can be performed more efficiently than those during an "ordinary" school lesson. Key words: plant alkaloids, teaching methods, teaching lesson, project method, laboratory exercise, biology, chemistry
