Board game stimulating logical thinking of children aged 5 to 7 years
Čtvrtníková, Katrin ; Kaslová, Michaela (advisor) ; Macháčková, Jana (referee)
The bachelor thesis supposed that the preschool children of the age 5-7 are able to play simple table games with rules. The goal is to investigate whether the preschool children in solving the game situations of a particular game"Goblíci jedlíci" are able to apply elements of logical thinking. The qualitative research has been used to prove it. The goal is based on the cognitive and development psychology of preschool age and on possibilities of pre-mathematical literacy. The teoretical part is focused on the preschool development in connection with the main topic of the thesis and the appropriate part of the game theory. The practical part contains the experiments and the data proceeding. For detailed observation and interpretation of the children's reactions and for data processing, description of situations, tabulation and comparison the video documentation has been used. The conclusion contains the core of experiments analysis with disscusion, and recomendations for practice. The experiment proved that children easily understand the rules and play with interest and the majority of them e able to apply some elements of logical thinking after some experience eventhough this ability has not been developed in their previous preschool education. Keywords: logical thinking development; cogitation,...

Creating images of fraction at the elementary school
Siblíková, Marta ; Tichá, Marie (advisor) ; Macháčková, Jana (referee)
This thesis "Creating images of fraction at the elementary school" is divided into theoretical and practical part. The theoretical part defines the subject matter of fractions in curriculum, deals with a mathematical literacy concept and introduces basic conceptions related to fractions and propaedeutic of fractions at the Primary School. The practical part consists of a preparatory research and a consequential research. The goal of the preparatory research is fractions knowledge mapping on Primary School pupils comparing to an expert knowledge acquired in the theoretical part. The consequential research focuses on confirming results of the preparatory research, respectively preferring the circle model off other models. It also checks if pupils get acquainted with other models (line segment, rectangle, and set of discrete objects). Key words Fraction, propaedeutic, models, representation, primary education, curricula.

Ways of creativity development in elementary mathematics education
Horáčková, Klára ; Tichá, Marie (advisor) ; Macháčková, Jana (referee)
3 TITLE: Ways of creativity development in elementary mathematics education SUMMARY: This thesis deals with creativity - from a general concept to a more specific perspective - creativity in mathematics lessons and textbooks at elementary schools in relation to the curriculum method and transformation of a number of textbooks towards unique teaching methods. The aim of this thesis is to describe the current situation on a selected sample of experimental groups - elementary school classes (two of them second year and three of them fourth year) which specialize on integration of pupils with specific learning and behavioral disabilities as well as extraordinarily talented pupils and thus provide the broadest possible range of pupils, which enables to find possible links between the used methods and creative teaching approach including creating one's own teaching materials and consequently searching for possible ways to develop creativity of pupils in relation to used methods, textbooks, other materials and forms of work. This thesis uses the following research methods: quantitative and qualitative research, empirical methods - observation, description, analysis. KEYWORDS: creativity, talent, imagination, originality, diagnosis, motivation

The Influence on Production of Secondary Metabolits in Tissue Culture Hypericum perforatum (L.)
Machačková, Jana ; Martin, Jan (advisor) ; Tůmová, Lenka (referee)
Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department of Farmacognosy Candidate Mgr. Jana Machačková Consultant PharmDr. Jan Martin, Ph.D. Title of Thesis The influence on production of secondary metabolits in tissue culture Hypericum perforatum (L.) Using of precursors is one of the biotechnological methods, where precursors are added to the culture medium. Callus and suspensions cultures of Hypericum perforatum L. were used. Fenylalanin and cinnamoyl acid in concentrations 20,0 g/l, 2,0 g/l and 0,2 g/l, resp. 25,0 g/l, 2,5 g/l and 0,25 g/l were used as precursors. The effect of precursors on the production of flavonoids was evaluated after 4, 24 and 168 hours. Cultures were cultivated on Murashige and Skoog medium with addition 2 mg/ml growthing hormon BAP. HPLC method for analysis was used. Generally, the highest increase of flavonoids was made by precursor fenylalanin in concentration B in callus and suspensions cultures. The top in production of quercitrin was detected in suspension cultures after application fenylalanin in concentration C after 168 hours cultivation (from 0,16 % to 0,22 %). Hyperosid was the most increased by fenylalanin in concentration C after 4 hours cultivation (from 0,24 % to 0,35 %). Cinnamoyl acid as precursor is not suitable for increase...

Rights to sign in Czech positive law
Macháčková, Jana ; Pítra, Vladimír (advisor) ; Růžička, Michal (referee)
and keywords The purpose of the thesis is to analyse the legal regulation and the system of registration of rights to signs, which are most commonly used on national as well as international markets, i.e. rights to a trademark, appellation of origin and a geographical indication. The aim of this thesis therefore includs definition of the registration system of the mentioned rights to sign with reference to their specifications, the registration ability conditions (taking into consideration the decision practise of the Industrial Property Office), as well as the different character of protection of their owners. Significant attention is also paid to the system of legal protection of the rights to sign with respect to the fact, that there exists the national, international and Communitary system of protection of these rights. The beginning of the thesis describes the structure of rights to sign, the corresponding specification of concept of intellectual and industrial property rights and it characterises the subject of industrial property rights with respect to the legal regulation, the conception of legal protection of industrial property rights and conditions of grant of protection. The introductory text deals with the general exposition to rights to sign and mainly to historical circumstances of...

Joint reflection in pre-servise primary school mathematics teacher training
Macháčková, Jana ; Tichá, Marie (advisor) ; Vondrová, Naďa (referee) ; Hošpesová, Alena (referee)
TITLE: Joint reflection in pre-servise primary school mathematics teacher training AUTHOR: Jana Macháčková DEPARTMENT: Department of mathematics and didactics of mathematics SUPERVISOR: Mgr. Marie Tichá, CSc. Abstract: The thesis focuses on the potential of development of pre-service and in- service teachers' self-reflection as one of the ways leading to development of pedagogical content knowledge. The thesis starts with definitions of the background concepts (teacher competences, pedagogical content knowledge, reflection, self- reflection, joint reflection). Also, as the experiments were carried out in the environment of fraction, the introductory part discusses issues related to interpretation and representation of fractions and sources of problems with fractions, their interpretation and representation. The first aim of the research was to monitor the quality of teachers' reflections. The subsequent goal was, on the basis of findings of this monitoring, to look for ways leading to refinement of this reflection. When monitoring and developing reflections, the main method used was the method of joint reflection of a video recording of a lesson. However, other methods were employed simultaneously (observation, group interview). Materials collected in the experiments (students' production, students'...

Perception and Interpretation of Fractions by Pupils in the 5th Grade of Primary School
Vašíčková, Jana ; Tichá, Marie (advisor) ; Macháčková, Jana (referee)
The essential part of this diploma thesis is a classification of works obtained from an investigation aimed on determination of conceptions of fractions by pupils in the fifth form of the primary school. The experiment consists of four tasks, which were given to children in four different classes. I have classified produced works according to bases of division, which I had established. Mainly concerned classifications are the thematic classifying, classifying in accordance with the "type of children's works" and classifying based on occurred interpretations of fractions. I was trying to find such criterions that would state in evidence of what conceptions and knowledge of fractions do the pupils in the fifth form have. According to gained results I think that I fulfilled this goal. When I was sorting the works of children, I found out that there is a huge amount of large-scaled works that can become basis for another research.

In vitro cultures of medicinal of plants - VII
Machačková, Jana ; Martin, Jan (referee) ; Tůmová, Lenka (advisor)
In vitro cultures of medicinal of plants - VII Elicitation is one of the methods that can be used to increase production or accumulation of secondary metabolites in explants cultures. There were used callus and suspensions cultures of Silybum marianum (L.) Gaertn. Derivate N-phenylpyrazin-2-carboxamid was used as abiotic elicitor in concentrations c1=1.159x10-3 mol/l, c2=1.159x10-4 mol/l and c3=1.159x10- 5 mol/l. The effect of elicitors on the production (flavonolignans of silymarin complex and flavonoid of taxifolin) was evaluated after 6, 12, 24, 48, 72 and 168 hours. Cultures were cultivated on Murashige and Skoog medium with addition 10 mg/ml α-naphtylacetic acid (α- NAA). HPLC method for analysis was used. The maximal content of flavonolignans was reached after elicitor application in concentration c2 after 168 h in callus culture (0,08%). However the highest content of silydianin was detected after application of elicitor in concentration c1 (0.11 %) in suspensions culture. The maximal content of flavonoid taxifolin was noted in of nutritient medium of suspensions cultures.
