Differentiation of different types of eggs by mass spectrometry
Švárová, Markéta ; Kučková, Štěpánka (advisor) ; Rusek, Martin (referee)
The aim of the diploma thesis was to distinguish bird species based on the expected different protein composition of eggs and their individual components using mass spectrometry. The obtained results could be possibly used to identify the animal origin of egg materials used in works of art. For the research, components of the eggs (yolk, egg white and their mixture) of nine available bird species were collected and dried - pheasant (Phasianus colchicus), domestic goose (Anser anser domesticus), domestic duck (Anas platyrhynchos domesticus), muscovy duck (Cairina moschata), chicken (Gallus gallus f. domestica) - four different specimens, Japanese quail (Coturnix japonica), pampas rhea (Rhea americana), red ore (Alectoris rufa), speckled guinea fowl (Numida meleagris). The samples were digested by the enzyme trypsin and prepared using ZIP-TIP for the next measurements by MALDI-TOF (Matrix-Assisted Laser Desorption / Ionization - Time of Flight) mass spectrometry. The obtained data were evaluated by Principal Component Analysis (PCA). The used method showed that the most bird species can be distinguished by yolks (with an approximately 95% success rate) and more than half of the species by egg white proteins (success rate 83%) and by the egg white and yolk mixtures (success rate 80%). Two samples of...

TITLE: Evaluation of the text difficulty of chemistry textbooks for secondary vocational schools AUTHOR: Lucie Vosyková DEPARTMENT: Katedra chemie a didaktiky chemie SUPERVISOR: PhDr. Martin Rusek, Ph.D. ABSTRACT: This thesis builds on previous researches of textbooks for primary, secondary and grammar schools and focuses on the analysis of the text difficulty of chemistry textbooks for secondary vocational schools of non-chemical focus. The aim of this work is to analyse the text difficulty of chemistry textbooks for non-chemical high schools, using the Nestlerova-Prucha-Pluskal method, to compare the text difficulty of chemistry textbooks for non-chemical high schools with primary and secondary school textbooks,and last but not least, to compare the text difficulty of particular chapters of choosen textbooks for primary and secondary schools. The results of the analysis are intended to provide teachers seeking support for their teaching with a possible criteria for a textbook selection. Based on the findings, the five analyzed series of textbooks can be divided into two groups. The first group consists of textbooks published by Scientia and Fortuna, whose text difficulty is at an appropriate level with a lower rate of technical terms. The other group consists of two textbooks published by SPN and...

Didactical Equipment of Czech Elementary School Chemistry Textbooks
Šubová, Šárka ; Rusek, Martin (advisor) ; Bílek, Martin (referee)
This thesis deals with the comparison of didactical equipment of Chemistry Textbooks for Basic Schools in the Czech Republic. The first part of the thesis is dedicated to the theory of textbooks and their research within it. The next part, which includes comparison of the textbooks, is pursued by the author from the perspective of two methods: the first being The Degree of Didactical Equipment and the second one The Determination of Didactical Criterion. According to the results of this thesis, the Chemistry Textbooks for Basic Schools in the Czech Republic are alike in its didactical equipment. There are similar structural components in each analysed textbook. There were found only small differences between the best didactically equipped textbooks (the textbooks of the publishers Nová škola and Fraus) and those with the lowest outcome (the textbooks of the publisher Taktik), although the time period between publishing the newest and the oldest textbook is more than 25 years. Due to homogeneity of the results and therefore lower possibility of comparing textbooks the method of the Determination of Didactical Criterion was applied. The method does not offer the final account of the most suitable textbook for school education but it presents different view of analysed textbooks, for example the...

Chemistry as the Part of Lower Secondary Science Education - The Comparison of Integrated and Subject Separated Approches
Heřmanová, Nikola ; Bílek, Martin (advisor) ; Rusek, Martin (referee)
Integrated science education on lower secondary school is a widely discussed topic and a possible solution for the future in many countries. This type of education is in line with increasing science knowledge and it minimizes repetition of topics during lessons, reducing both the burden on teachers and the pressure on pupils. The bachelor's thesis deals in the theoretical part with a comparison of teaching systems of several selected countries with a focus on teaching science subjects on lower secondary school, especially on the position of chemistry. The practical part is focused on the comparison of these countries according to their results in the international survey TIMSS and PISA, taking into account impact of an integrated or subject-separated approach to science teaching. There was no clear difference in the impact of an integrated or separate approach to science teaching in the results of the participating countries in the international comparative survey TIMSS and PISA. It is only possible to see better motivation of pupils to learn these subjects in the case of an integrated approach, as can be seen from the results in Singapore, the United Kingdom or Turkey.
