Teaching chemistry as a general education subject in Slovenia
Hahnerová, Veronika ; Bílek, Martin (advisor) ; Pelikánová, Monika (referee)
The bachelor thesis examines the Slovenian education system with a focus on chemistry teaching as a general education subject. The theoretical part analyses the content of the chemistry curriculum for students in primary and secondary schools, focusing not only on curriculum documents but also on the practical aspect, including interviews with actors in Slovenian chemistry education. The results of the work include analyzes of selected textbooks within the Slovenian chemistry education system, starting with the first encounter with chemistry content within the integrated subject of natural sciences (Naravoslovje) in the sixth grade up to the subject of chemistry in the fourth year of high school education. The bachelor thesis examines the opinions and attitudes of stakeholders in the Slovenian education system towards chemistry as a general education subject in relation to the current curriculum documents for secondary education, thus providing a wealth of inspiration for the current curriculum changes being implemented in the Czech Republic.

Escape Games as a Means of Motivation to Practice Chemical Calculations in High School
Langerová, Lucie ; Bílek, Martin (advisor) ; Koperová, Dominika (referee)
Escape games have experienced tremendous growth in the market for action group entertainment in recent years and show potential for educational use as well. The bachelor's thesis focuses on designing two didactic escape games as an innovative tool to revitalize the teaching of chemical calculations in high schools. The research section of the thesis introduces issues related to student motivation to learn, the history, and current use of games in education with an emphasis on escape games and their potential in teaching chemistry and chemical calculations. The thesis also provides an analysis of the curriculum related to chemical calculations in the educational programs of four selected high schools, which revealed considerable diversity and range of treatment of the topic of chemical calculations. The practical part of the thesis is dedicated to the design and evaluation of escape games "Night Escape from Hogwarts" and "Robotic Apocalypse". The goal of these games is not only to practice chemical calculations, which many students find challenging and difficult to understand, but also to increase their motivation to learn chemistry. The games were pilot tested by a group of high school students and evaluated by high school chemistry teachers, who provided feedback on their anticipated...

Reaction of protein with nitric acid as a topic for an inquiry-based activity
Hanušová, Barbora ; Kolář, Karel (advisor) ; Bílek, Martin (referee)
The teaching experiment has an indispensable role in teaching. The object of investigation of this thesis is to study the interaction of nitric acid with proteins. The course of the reaction is motivating and inspiring for pupils and students due to the observable changes that occur. The course of the reaction involves asking several questions. In order to answer them, the student must explain the nature of the reactions. A bioorganic model based on simple reactions carried out on a dot-plate is sufficient to explain the reaction process. The main motivation for this activity was to enrich the existing range of simple teaching experiments in organic chemistry and biochemistry with an experiment using exploratory methods in the context of bioorganic models. KEYWORDS nitric acid, proteins, xanthoprotein reaction, school experiment

Optimization of vortex pump
Šmíd, Pavel ; Bílek, Martin (referee) ; Pochylý, František (advisor)
The aim of this labor is to optimize the vortex pump. When this pump should find application on the field of health like human heart for extracorporeal circulation. We will deal with the analysis of shear stress in the pump and its size of it and consider the use nonwetting surfaces to reduce the shear stress values. All our analysis will be made by CFD calculations.

Optimization of a sinusoidal pump
Sluše, Jan ; Bílek, Martin (referee) ; Pochylý, František (advisor)
The aim of the diploma thesis is to design the technical solution of minimization of frictional losses, which occur when using a sine pump at position of the shaft locking and on the impeller wheel. The losses originating from the frictional forces have a negative influence on the lifetime of individual parts and economy of the pump. In the first part the author describes sine pumps from the constructional point of view and the main producers are mentioned. The second part contains suggestions on the parameters of the pump and various possibilities of solutions. The last part covers the experiment and conclusions.

Modeling of flow in ejector
Bílek, Martin ; Habán, Vladimír (referee) ; Štigler, Jaroslav (advisor)
This diploma thesis deals with the flow modelling in the ejector using the FLUENT software. It develops a diploma thesis created in the past, where a mathematical flow model in the ejector was created and experimentally tested. The aim of this work is to analyze the ejector calculations and to model a flow in an ejector of the same shape as in the experiment and under the same conditions, too. Another objective was to assess the influence of the throat length and to examine if the pressure in the ejector mixing chamber remains constant. Finally, the disagreement between the experimental figures and the ones gained from the mathematical model of the ejector are discussed.

Chemistry and integrated teaching of natural sciences in secondary school
Dobečková, Markéta ; Kričfaluši, Dana (advisor) ; Ganajová, Mária (referee) ; Bílek, Martin (referee)
The doctoral thesis deals with the specification of factors that influence the implementation of integrated teaching positively or negatively. It presents the results of research mapping the current situation regarding integrated teaching in secondary schools in the Czech Republic. It also presents the opinions of secondary school teachers on integrated teaching and the possibilities of its implementation. The results were obtained by questionnaire survey and Q methodology, which was designed for the online environment via Google Slides. Among other things, the research results point to factors from a total of 4 areas, which, according to the respondents, play an important role for the integration of integrated teaching in education. These areas are undergraduate and postgraduate teacher education, external conditions (for example, the approach of school management), the third area is focused on the teacher's personality, and the last area is focused on pupils and their parents. It follows from the obtained results that the factor positively influencing the implementation of integrated teaching (hereinafter referred to as IT) is the perception of the importance and content of IT by teachers. Teachers mostly perceive integrated teaching positively, they believe that it encourages students' interest...

Characterizing sample questions for medical school admission exam using Bloom`s revised taxonomy of learning objectives
Vršková, Nikola ; Rusek, Martin (advisor) ; Bílek, Martin (referee)
This thesis is focused on characterising sample questions for medical school admission exam using Bloom`s revised taxonomy of learning objectives. The aim of the thesis is to evaluate the distribution of question types within the dimension of knowledge and the dimension of cognitive processes. Secondly, to compare these results with the requirements and opinions of professors teaching at medical faculties. The theoretical part provides basic information about the organization of the admission exams to medical faculties, and then summarizes basic information about the original and revised Bloom's taxonomy. In the practical part of this thesis, model questions are analyzed using the revised Bloom's taxonomy. Secondly, the teachers from the medical faculties were asked their opinion on the most important abilities of the medical students and on the possible ways to test them. The results show the stratification of question types according to the dimensions of Bloom's taxonomy. The analysis reveals that the model questions are mainly focused on testing the lower levels of the cognitive dimension, and the first two levels of the knowledge dimension. However, according to the respondents from among the teachers at medical faculties, higher cognitive abilities are more desirable for students. The results...
