Freshman chemistry teacher students' understanding of basic chemical concept and corresponding representations with a special focus on chemical equations
Hamerská, Lucie ; Rusek, Martin (advisor) ; Bílek, Martin (referee)
This bachelor thesis deals with the topic of chemical equations as one of the basic chemical concepts. The theoretical part is devoted to the teaching of chemistry from the point of view of curriculum documents, the specifics of this school subject are presented, and the chemical triplet of representations is introduced. Subsequently, the thesis takes a closer look at the topic of chemical equations and their balancing. The eye-tracking method is also briefly introduced. The aim of this bachelor thesis is to map freshman chemistry teacher students' understanding of the particulate nature of matter, with an emphasis on chemical equations as a transcript of chemical reactions. The research combines both quantitative and qualitative methods. Twenty-four students participated in the initial written testing. Based on their performance on the test, students were divided into three categories. For the next phase of the research, the sample was narrowed down to 11 respondents. The eye-tracking method combined with think-aloud and interviews was used to obtain more detailed information. While the written pretest mainly tested knowledge of basic chemical concepts, the eye-tracking pretest focused more specifically on chemical equations and their presentation using different chemical representations.

Svobodová, Lenka ; Tichá, Marie (advisor) ; Novotná, Jarmila (referee)
TITLE: Developing activity and creativity in teaching fractions in grades 6 to 7 AUTHOR: Bc. Lenka Svobodová DEPARTMENT: Department of Mathematics and Mathematical Education SUPERVISOR: Mgr. Marie Tichá, CSc. ABSTRACT: The thesis consists of a theoretical and an empirical part. The theoretical part looks at the cognitive process of pupils and possible ways of their motivation during fractions teaching. Furthermore, it outlines causes of lack of understanding of fractions and re-education interventions. The empirical part is based on a qualitative research whose main objective was to determine how the pupils are able to solve fractions exercises independently and creatively and what mistakes they make. Various methods of data collection were used, such as interview with teachers on issues of fractions teaching in elementary schools, non- standardised test with fractions exercises and additional interview with the tested pupils. This part also describes the preparation of the research, the research itself and its results KEYWORDS: fractions, interpretations, representations, models, misunderstandings, mistakes, teaching approaches

Blood, honour and horror. Representations of siege warfare in siege journals of British defenders of Bergen-op-zoom in 1747.
Wohlmuth, Petr ; Storchová, Lucie (advisor) ; Schreiberová, Zuzana (referee)
This Master's degree thesis, named Blood, honour and horror. Representations of siege warfare in journals of British defenders of Bergen-op-zoom in 1747, adheres at specific genre of historical anthropology of war and military. It poses questions regarding ana-lysis of contemporary culture of war and its individual variables, their interdependence and changing configuration during the siege of Bergen-op-zoom in 1747, during culmination point of War of Austrian Succession. Meaning of this text consists of an effort to discover alternative way of treating historical sources and to depart traditional conservative methods of analyzing the war conflict using national or confessional military stereotypes, essential features of key actors or theoretical normative of military science. The text comes to conclusion that most irregular and dramatic character of the siege of Bergen-op-zoom was primarily caused by profound misunderstanding between defenders and attackers regarding culture of war, especially acceptable definition of military honour and of legitimate combat techniques.

Lilliputians.Representations of the bodily "difference" in the Prague's freakshow culture 1820-1940
Herza, Filip ; Storchová, Lucie (advisor) ; Kolářová, Kateřina (referee)
In the following essay, I focus on the representations of bodily "difference" in the Prague's freakshow culture, particulary on the displays of the so called "Lilliputians", which were popular among the public from the beginning of the 19th Century to the 40's of the 20th Century. Firstly, I introduce the Prague's curiosity exhibitions as a specific social praxis and I compare them with similar displays in Europe and the United States. In the second part of this essay, I try to analyse those exhibitions critically, using the concepts from the present disability studies discourse. I deal with the bodily "otherness" as a category of difference, which arises from the intersection of different ideologies. According to the point of view, this category shaped the individual and collective identities and fostered the social hierarchies of the time. Throughout the essay, I focus on the dis/continuities in the imagination of bodily "difference" and I try to describe the specificity of the Czech freakshow tradition. Key words: 19th Century, body, representations, bodily difference, abnormality, ideology

Automorphism Groups of Geometrically Represented Graphs
Zeman, Peter ; Klavík, Pavel (advisor) ; Nedela, Roman (referee)
In this thesis, we are interested in automorphism groups of classes of graphs with a very strong structure. Probably the first nontrivial result in this direction is from 1869 due to Jordan. He gave a characterization of the class T of the automorphism groups of trees. Surprisingly, automorphism groups of intersection-defined classes of graphs were studied only briefly. Even for deeply studied classes of intersection graphs the structure of their automorphism groups is not well known. We study the problem of reconstruct- ing the automorphism group of a geometric intersection graph from a good knowledge of the structure of its representations. We mainly deal with interval graphs. Interval graphs are intersection graphs of intervals on the real line. They are one of the oldest and most studied classes of geometric intersection graphs. Our main result is that the class T is the same as the class I of the automorphism groups of interval graphs. Moreover, we show for an interval graph how to find a tree with the same automorphism group, and vice versa. 1

Landscape, Place, Space: a case study of Vraný nad Vltavou
Sequensová, Linda ; Uherek, Zdeněk (advisor) ; Grygar, Jakub (referee)
The topic of this diploma thesis is the suburban landscape, place and space of the Vrané nad Vltavou municipality located in close proximity to the capital city of Prague. The author approaches the suburban landscape as a specific type of landscape, which combines elements of urban and rural character. The author describes the manifestations of this landscape liminality using ethnographic methods and demonstrates the diversity of spatial structures with her own visual documentation, together with a depiction of the specificity of not only the researched landscape, but also the specificity of the suburb itself in the Czech context. Through the concept of the landscape applied in the socio-anthropological discourse, the author connects the material aspects of the natural environment with the social level of ideas, feelings, and experiences that everyone forms in contact with the landscape. In this sense, the landscape is never finished and neutral, but on the contrary, it is constantly negotiated and confirmed in the daily interactions of human and the landscape. The same holds true of the landscape, which is the subject of suburbanization processes changing its character. Therefore, on the one hand, the author depicts the character of the researched suburban landscape, on the other hand, she maps...

Simple categorization of mathematical objects: Examining students' decisions
Janda, David ; Vondrová, Naďa (advisor) ; Simpson, Adrian (referee) ; Klusák, Miroslav (referee)
The aim of the thesis is to describe the decision making process of students in the so-called simple categorization, i.e., decision whether a particular object is or is not an element of a category. This process is examined in the context of categories of mathematical objects. The theoretical part of the thesis presents arguments why the study of simple categorization of mathematical objects is important for mathematics education. These arguments are not only based on the available literature in mathematics education, but also partly draw on historical, mathematical and psychological literature. The practical chapters of the thesis describe the design and piloting of a research tool suitable for this research. The dominant elements of this tool are the measurement of the binary answers (yes / no) of the respondent and of his/her reaction time. This tool is then used in the Main study based on mixed, qualitative-quantitative methodology. It was found that with the help of the proposed tool, while adhering to appropriate methodological rules, it is possible to distinguish different approaches of respondents to categorization. In addition, the basic patterns in the decision-making process of the respondents were described. These are, for instance, differences in the categorization of examples and non-...

Conceptions of area and volume of pupils at the elementary school
Tůmová, Veronika ; Vondrová, Naďa (advisor) ; Coufalová, Jana (referee) ; Kubáček, Zbyněk (referee)
Conceptions of area and volume of pupils at the elementary school Veronika Tůmová ABSTRACT: The aim of my thesis is to investigate how the conceptions of area and volume are built, what the major pitfalls and problems are, what skills and strategies are helpful for solving problems and what are the frequent unsuccessful strategies and pupils' misconceptions. I used the concept of the hypothetical learning trajectory as a tool to describe this process. Based on existing research review, I compiled two hypothetical learning trajectories - one for area and one for volume. The crucial building blocks that were identified based on these trajectories are: space abilities, structuration of space into arrays of units and multiplicative thinking. A test was designed to measure these factors and the correlation of these factors with success in volume and area problems ranged from week (multiplicative thinking) to very strong (spatial abilities). These findings confirm that these factors constitute an important part of the hypothetical learning trajectory for both concepts. Several structuration tasks were selected to investigate pupils' structuration skills and mistakes in more detail. Three main categories of problems were identified in the pupils' solutions: incorrect space structuration, disconnection between...
