Adamec, Martin ; Beneš, Pavel (advisor) ; Bílek, Martin (referee) ; Šmejkal, Petr (referee)
The use of information and communication technologies, including computer graphics, in teaching chemistry is one of the frequent issues of contemporary chemistry didactics. Current publications are mainly focused on displaying structure of chemical compounds and symbolic form of chemical reactions. This thesis offers a more complex view on the computer graphics and other means of information and communication technologies - their possibilities and limits of use in teaching. The goal of the thesis is to provide an overview of selected computer-graphics technologies and to discuss their role during current curricular reform, based on current problems identified by students attending chemistry-teacher training courses and chemistry teachers. Usability of selected elements in pre-teaching and teaching phases was checked. Innovations of contemporary teaching methods were proposed using computer graphics. The thesis is focused on the area of visualization of educational content with use of computer graphics, computer-assisted innovation of methods and educational content, computer games and the role of computer graphics in didactic transformation. Two textbooks for lower-secondary and upper-secondary schools were created. These textbooks contain newly developed parts using computer graphics. According to...

Metelková, Iva ; Marádová, Eva (advisor) ; Beneš, Pavel (referee)
TITLE: Substances present in every day life representing threats to the health of older- shool-age children AUTHOR: Iva Metelková DEPARTMENT: Department of Education SUPERVISOR: PaedDr. Eva Marádová, CSc. ABSTRACT This thesis deals with the substances present in everyday life, which may pose risk for human health. In the theoretical part of this work groups of hazardous substances are characterized. For selected representatives of each group are specified. negative impacts on human health and outlines the mechanisms of action. Individual chapter is devoted to physical and psycho-social development of school age students using knowledge of developmental psychology. Substances which on the other way help detoxify the body and help it to be resistant to the effects of potentially hazardous substances are also mentioned. The aim is to map the practical awareness of the hazardous effects of selected substances among pupils attending upper primary school. Questionnaire survey found that students do not attach danger arising from the presence of potentially hazardous substances in foods, cosmeticsand household. Therefore I recommend pay attention to information about risks arising from long term exposure to these substances. KEY WORDS: harmful substance, health protection, food hazards, drugs

The creation and utilization efficiency of multimedia learning materials on teaching chemistry in high school (transition elements)
Veřmiřovský, Jan ; Bílek, Martin (advisor) ; Beneš, Pavel (referee) ; Ganajová, Mária (referee)
Topic: The Efficiency of Designing and Applying the Multimedia Study Materials in the Chemistry Instruction at Grammar schools (Transition Elements) Abstract Numerous researches prove, that the computer-supported learning content presentations are frequently applied within the process of instruction but the available results are general, global without focusing on respondents' age structure, detecting their interest in working with presentation programmes or correlation to teachers' computer literacy, i.e. using and designing their own computer-supported presentations of the learning content. These were the main reasons why the dissertation thesis focuses on the frequency of designing and using this type of presentations and multimedia objects according to the computer literacy level and the length of respondents' teaching practice in chemistry at grammar schools in the Czech Republic, mainly in the Moravian-Silesian region. The explorative methods were applied in the pedagogical research, i.e. the questionnaire method (traditional questionnaire and the questionnaire with assessment scales) and the Q-methodology. The research sample consists of 203 chemistry teachers in the traditional questionnaire and 99 ones in the questionnaire with assessment scales from all regions of the Czech Republic; the random...

Identification of Terpenoid Resins in Artworks by Gas Chromatography
Jelínek, Jan ; Beneš, Pavel (referee) ; Hrdličková Kučková, Štěpánka (advisor)
Terpenoic varnishes are used in artworks since 11th century. Their task is to protect the artworks against the adverse effects of the environment and frequently they complete the artistic page. Although synthetic varnishes are currently widely used, especially in the case of modern art, the use of natural materials is still widespread and not only in the restoration of historical paintings and polychromy. In order to prepare terpenoic varnishes, rich supply of natural resins is used (damare, mastic, copals, colophony etc.). These resins differ in their composition and therefore they have various physical properties such as fragility, solubility, and not least the various darkening of varnish. For these reasons, it is necessary to know their composition, in order to be safely removed during restoration and subsequently replaced by a varnish of the same material composition. Gas chromatography is the most widely used analytical method for determination of natural resins, using a number of derivatizing reagents. The task of this thesis was to find the best separation conditions for the identification of resins by gas chromatography combined with flame ionization detector (GC-FID).

Identification of Protein Binders Contained in the Artworks by gas Chromatography
Köhlerová, Veronika ; Beneš, Pavel (referee) ; Hrdličková Kučková, Štěpánka (advisor)
Painters often used a protein binding agents such as various types of animal glues, casein or eggs, either whole or their individual parts for preparation of many different types of temperas. The determination of the proteinaceous binder is essential in order to choose a suitable conservation method and for identification of the painting technique. This diploma thesis aims to define the most suitable conditions to determine the proteinaceous binders by gas chromatography with flame ionisation detector (GC-FID). Firstly, the optimal conditions needed for separation of individual amino acids, which are necessary to distinguish the protein binding agents, were set. Secondly, the empirically define conditions for hydrolysis of proteins, which breaks down proteins into the individual amino acids, were found.
