Pupils'work with building blocks during breaks
Chvátalová, Šárka ; Jirotková, Darina (advisor) ; Slezáková, Jana (referee)
The diploma thesis deals with a free play with building blocks during breaks. The aim of this work is to find out how the free play with building blocks is beneficial for pupils at primary school. The whole work is divided into 3 chapters and each of them is concerned with the importance of the play in one specific area. The first part deals with the benefits of the play for the development of pupils' mathematical skills, the second part deals with the benefits of the play for the development of social skills among pupils. The third part is then aimed at the value of observing pupils during the free play for teachers. The research was conducted using observation during which photographs and video records of pupils' play were made. The photographs and the video records were consequently analyzed from the perspective of all 3 categories mentioned earlier. Key words building blocks, math, geometry, social skills, communication, cooperation, school break
Exactness of geometric constructions
Skálová, Zuzana ; Moravcová, Vlasta (advisor) ; Halas, Zdeněk (referee)
The topic of this thesis is exactness of geometric constructions. The first chapter outlines the importance of exactness in drawing and different methods, that were used to get more accurancy in drawing in the past. The second chapter describes in detail several constructions contributing to accurate drawing. These auxiliary con- structions solve frequent problems, for example a need for drawing an intersection point of two lines forming a very small angle etc. The last chapter describes a research realized with middle and grammar school students. The aim of the research was to determine whether the auxiliary contructions really have a positive impact on the accurancy of drawing. 1
Rotor design of a Line-Start Synchronous Reluctance Machine for Industrial Applications
Žíla, Jakub ; Knebl, Ladislav (referee) ; Bárta, Jan (advisor)
This diploma thesis deals with design of rotor of synchronous reluctance machines. There is a theoretical description of rotor geometry of synchronous reluctance machine that respects natural flow of magnetic flux inside complete rotor. The parametric model of rotor is made with usage of ANSYS Maxwell and Matlab software. Furthermore, the parameters of the machines are confirmed using the same program. Finally, changes of motor parameters are observed in connection with different rotor geometries.
Geometry in Motion
This diploma thesis deals with the influence of geometric abstraction and op art on art and the use of new media in video art. Above all, it focuses on selected Czech artists of these directions and their work. The thesis is divided into two main parts, theoretical and practical. The theoretical part of the thesis deals with the beginnings of geometric abstraction and its expansion, especially in the second half of the twentieth century in Bohemia. Important names of this direction are mentioned here, namely Jan Kubíček, Hugo Demartini, Zdeněk Sýkora and Milan Grygar. Following the geometric abstraction, there are tendencies to create geometric optical illusions outlined in the chapter devoted to op art. The work of Vladislav Mirvald and Radoslav Kratina is highlighted here. In addition, it devotes itself mainly to the penetration of new media into video art and overall to the arts as such. Mr and Mrs Vasulka are mentioned as representatives of video art. They have contributed to the development of this direction, primarily through their creativity and inventiveness during their creative work. The text describes the issue not only from a global point of view, but also focuses on the development of Czech art. The practical part reflects the knowledge of the theoretical part and unifies the elements of the above-mentioned directions by creating an authorial video using mainly the principles of geometric abstraction.
Loci of given properties
This bachelor thesis focuses on the description of the loci of given properties and its use in solving of the simple tasks in high schools. It is also focused on the analysis of more difficult problems related to the conic sections. These problems are solved in planimetric or analytic form. There is also a chapter dealing with the axial affinity. It extends the curriculum at high schools.
Origami in Primary School Education
The thesis titled /Origami in primary lessons/ focuses on the practical use of Origami, especially in arts and mathematics classes. It contains lesson plans on various topics and a detailed reflection of the lessons taught at a primary school.
Comparing methods of mathematics teaching with a focus on geometry
Stříbrná, Eliška ; Tůmová, Veronika (advisor) ; Kloboučková, Jaroslava (referee)
The goal of this diploma thesis is to observe, characterize ale reflect two well-known methods of teaching mathematics - so-called classical method and method according to professor Hejný, on the example of two second grade class teachers of elementary school with a focus on geometry. In the theoretical part I list several research works concerning class room observation. I use these to set up methodology of my own research. Moreover, the methods are characterized according to the literature and the analysis of the textbooks. Also the outputs of the Framework Education Programme (in Czech "Rámcový vzdělávací program") are presented in this theoretical part. I use these outputs to evaluate whether the method leads students to what they should know. The practical part consists of observing lessons of two teachers, my own teaching experience in the given classes and final questionnaire for students. Data collected from these observations are analysed with the help of qualitative and quantitative methods. The representative of the so-called classical method put emphasis on repetition and system. He usually asks students questions that require a shorter response. Students do not enjoy the school and geometry that much, but the knowledge results are quite good. The representative of the method according...
Geometric Proofs
Hanusová, Tereza ; Štěpánová, Martina (advisor) ; Halas, Zdeněk (referee)
Title: Geometric Proofs Author: Tereza Hanusová Department: Department of Mathematics Education Supervisor: RNDr. Martina Štěpánová, Ph.D., Department of Mathematics Edu- cation Abstract: This Bachelor's thesis treats such proofs of mathematical theorems in which pictures and secondary school geometry play a significant role. Its aim is to promote an unusual approach to theorem proving which enables to literally see the way they function. The proofs described include three categories: figu- rate numbers, polygons and areas of plane figures with curved boundaries. The thesis can be useful to teachers to liven up their secondary school mathematics lessons or to students of maths-oriented programmes to enrich their knowledge by an unusual approach to theorem proving. Keywords: proof, geometry, figurate number, polygon, area of plane figure 1
Geometrie komplexních čísel
This thesis deals with a theory of complex numbers and contains three main parts. The first part is dedicated to the disquisition of complex numbers as we know it from secondary schools. In this part we summarize the basic knowledge of the secondary schools and the use of complex numbers is illustrated by a few arithmetical problems. In the second part we deal with complex numbers in terms of vector spaces and algebraic structures and compare secondary school and university disquisition of complex numbers. In the third part we apply the knowledge from the previous chapters on several problems including problems from mathematical olympiads.
Influence of size and geometry of nanoparticles on cellular internalization pathways
Číhařová, Barbora ; Španielová, Hana (advisor) ; Lišková, Petra (referee)
Nanoparticles can be used in biomedical disciplines as carriers for transport of diagnostic as well as therapeutic substances into cells. Variety of different shapes, sizes and different compositions are used experimentally. Despite the discoveries already made in this area, the exact nature of the interaction between a nanoparticle and a cell has not been fully understood yet. The objective of this thesis is to provide the knowledge about possibilities of utilisation and aspects influencing the interaction between the cell membrane and several types of nanoparticles: liposomes, gold nanoparticles and virus-like nanoparticles. The comparison shows that generalisation of the mechanism of nanoparticle entry into the cell is problematic, although it seems that the spherical nanoparticles with the diameter of 50 nm provide the most efficient entry.
