Optical characterization of InAs nanowires
Hošková, Michaela ; Ligmajer, Filip (referee) ; Musálek, Tomáš (advisor)
This bachelor thesis deals with the fabrication and optical characterization of InAs nanowires. Physical vapor deposition is used for the fabrication of nanowires via method selective epitaxy in the MBE chamber. The growth conditions for the formation of nanowires are optimized and their dimensions are characterized by a scanning electron microscope. Confocal spectroscopy and electron energy loss spectroscopy are employed for measurement of the optical response and the influence of the geometry of individual nanowires is studied. The motivation is the development of a new optical method that monitors nanowires directly during growth in the MBE apparatus.

Pupils' Opinions on Using Teaching Methods and Forms of Teaching in Science Lessons
Hošková, Michaela ; Hlaváčová, Lucie (advisor) ; Nejedlý, Adam (referee)
The theoretical part of the thesis includes an introduction to concepts such as teacher learning, teacher typologies, and the transmissive and constructivist conceptions of teaching. It also describes pupil learning, pupil typologies and their learning styles and strategies. The next part of the theoretical section is concerned with teaching methods and forms of teaching. The history of teaching methods and forms and their different classifications are described. Examples of selected teaching methods (explanation, discussion, didactic games, project-based learning, critical thinking methods and brainstorming) are also included along with a basic description and evaluation of the positives and negatives of using them in teaching. In the practical part, the research is presented in the form of a questionnaire survey, in which a total of 270 respondents from primary schools and grammar schools from 9 regions participated. The results are processed into graphs and tables with labels and evaluated using Welch's t - test, Mann - Whitney statistical test and two relative frequencies test. The questionnaire includes questions related to the frequency of use of different methods and forms of teaching and to determine the pupils' opinions about each method and form from several aspects. The results showed...

To the methodology of teaching history of Holocaust at Primary schools with didactically modified text and iconographic sources
HOŠKOVÁ, Michaela
This thesis called "To the methodology of teaching history of Holocaust at Primary schools with didactically modified text and iconographic sources" is taking into account the relationships between the newest history findings considering the holocaust topic. It is dealing with their topic range and reflexion in the school materials for the secondary school students in the context of the Framework Education Programme. The thesis gives detailed didactic analyses of the topic including the options of the excursion education and compilation of the particular selection of the didactically modified texts and iconographic sources with methodic commentary.
