The diploma thesis consist of three parts. The first part is composed of theory of geometry, sumary basic geometrical concepts in subject-matter for elementary school, situate Math to educate programme and importance teaching with computer today. The second part I wrote as manual referenc book for teacher, who will teach according to my material. Last part describe experiment, which I make in 4. class of basic school. The third part describes pupils work witk programmes SMART Notebook and GeoGebra.

The topic of this thesis is digital methods in process of architectonic designing, analysis, research and application of new methods. This thesis describes theoretical sources, which are useful for creating new digital methods. Thesis systematically describes existing methods and analyzes application on various projects. In thesis is also described research of new, own methods and preview of application.

To study coisotropic reduction in the context of deformation quantization we introduce constraint manifolds and constraint algebras as the basic objects encoding the additional information needed to define a reduction. General properties of various categories of constraint objects and their compatiblity with reduction are examined. A constraint Serre-Swan theorem, identifying constraint vector bundles with certain finitely generated projective constraint modules, as well as a constraint symbol calculus are proved. After developing the general deformation theory of constraint algebras, including constraint Hochschild cohomology and constraint differential graded Lie algebras, the second constraint Hochschild cohomology for the constraint algebra of functions on a constraint flat space is computed. / Um koisotrope Reduktion im Kontext der Deformationsquantisierung zu betrachten, werden constraint Mannigfaltigkeiten und constraint Algebren als grundlegende Objekte definiert. Wichtige Eigenschaften verschiedener zugehöriger Kategorien, sowie deren Kompatibilität mit Reduktion werden untersucht. In Analogie zum klassischen Serre-Swan-Theorem können constraint Vektorbündel mit bestimmten endlich erzeugt projektiven constraint Moduln identifiziert werden. Außerdem wird ein Symbolkalkül für constraint Multidifferenzialoperatoren eingeführt. Nach der Entwicklung der allgemeinen Deformationstheorie von constraint Algebren mithilfe von constraint Hochschild Kohomologie und constraint differentiell gradierten Lie-Algebren, wird die zweite constraint Hochschild Kohomologie im Fall eines endlich dimensionalen constraint Vektorraums berechnet.

This work compares and evaluates several math's textbooks for secondary school where we can find schoolwork from plane geometry. The aim of this work is drawing the main advantages and disadvantages of those textbooks, evaluating whether all textbooks contain themes which are required by School Curriculum and interpretation of a questionnaire survey among teachers of mathematics. In the last chapter, it is described how a new ideal textbook of plane geometry wouldlook like. Those were taken on the grounds of gained information from my questionnaire survey. Themes which cannot be found in compared textbooks for secondary schools are a part of recently made textbook since it is not necessary to know any new terms for their understanding. Key words: geometry, teaching geometry, textbooks, polygon, circle

This thesis Models of Lobachevskij's geometry and the possibilities of their use at secondary school focuses on one kind of non-Euclidean geometries, the Bolyai - Lobachevskij's geometry. The first chapter describes the history of non-Euclidean geometry, shows difficulties of understanding of one publication dedicated to these problems by current students of secondary schools and shows some chosen methods in the didactics of mathematics, especialy the constructivist method. The second chapter is dedicated to elemental concepts of projective geometry, Bolyai - Lobachevskij's geometry and it shows its basic models. It further analyses the specific features of this kind of geometry in Beltrami - Klein's model, especially mutual positions of straight lines. This theses further contains a set of gradual tasks. The third chapter is dedicated to the description of a didactical experiment. In this experiment were students of secondary school acquainted with this theory and tasks, which they solved. Student's solution were writen down and than analysed in the constructivist methodology term in the didactics of mathematics.

In this thesis we study projective perspective on planar euclidean geometry. First we take an euclidean construction and transform it into the projective language. Then we discover and show principles of this transformation. We show equivalence between complex points I, J and some euclidean structures. Moreover we study conics, triangles, polygons and circles. We build this thesis on examples. 1
