Dvořáková, Irena ; Zemanová, Jana (referee) ; Vespalcová, Milena (advisor)
The diploma thesis is dealing with the determination of caseins in lyophilised samples of milk using the method of capillary electrophoresis (CE). This method was optimised and verified by Ivana Micikova in her diploma thesis in 2009. The theoretical part of the diploma thesis gives information about the chemical compound of cow's milk. Caseins and their usage in the food and non-food industries are described in a separate unit. Impact of both the nutritional and non-nutritional factors on the composition of the milk is discussed further. The description and the principles of the CE and a list of the methods of CE used in the last several years are stated at the end of this part. The experimental part is focused on the preparation of the solutions, process of casein isolation and its analysis. It summarises the setting of the experiment, sampling and sample processing and the composition of the feeding mixtures. The diploma thesis has arisen on the basis of the cooperation of the Institute of Food Science and Biotechnology, the Faculty of Chemistry, Brno University of Technology and the Research Institute for Cattle Breeding, Ltd., Department of Animal Nutrition Physiology in Pohorelice.

Demonstrating set of electric circuits
Kohout, Václav ; Koudelková, Věra (advisor) ; Dvořáková, Irena (referee)
The aim of the bachelor's thesis is to develop a demonstration kit for teaching electrical circuits at lower secondary school. The thesis briefly discusses the necessary parameters of the demonstration set depending on the content of the curriculum taught in lower secondary school. The criteria used in the selection of a physical aid are also mentioned. These are applied in the search of existing demonstration kits applicable in school physics. The thesis further describes in detail the development of individual components and summarizes the definitive version of the kit developed by us. The work considers the experience of testing the developed set in the teaching of physics at lower secondary school - with an emphasis on the elimination of identified shortcomings. The work provides suggestions for the use of the developed set in teaching physics at lower secondary school.

Application of an interactive whiteboard for physics education
Šimková, Jana ; Dvořáková, Irena (advisor) ; Drozd, Zdeněk (referee)
In terms of my master thesis I accomplished a partial research of information about using interactive whiteboard at school in the Czech Republic and abroad. I described the use of modern technologies and interactive whiteboards in the classes. I compiled my own experience and knowledge obtained during the visitation classes using an interactive board. Part of the evaluation was a questionnaire lled out by students. In the questionnaire, I examined their opinions of the bene ts of working with the interactive whiteboard in classes. In my thesis I focus on the ACTIVboard interactive whiteboard. I described the basic functionality of the ACTIVstudio application and created sample demonstration workbooks intended for teaching physics. The demonstration workbooks has been divided into three categories according to the way of using and describing their properties in detail. In the conclusion the results and future prospects of my work are summarized. The appendix contains three demonstration workbooks in text format. All created demonstration workbooks and templates for solving the physics problems and the text of the thesis are attached in electronic format on the enclosed CD-ROM.

Title: Physics education of students and teachers in the Heureka project Author: RNDr. Irena Dvořáková Department: Department of Physics Education, Faculty of Mathematics and Physics, Charles University in Prague Supervisor: doc. RNDr. Leoš Dvořák, CSc., Department of Physics Education, Faculty of Mathematics and Physics, Charles University in Prague Abstract: This doctoral thesis is aimed at physics education of students and teachers in the Heureka project. The introductory part concerns the brief outline of the current state of physics education both in the Czech Republic and around the world. The next chapters describe the genesis of the project, characterize its main principles and give several examples of methodological sequences in which the application of these principles is shown. The impact of these ideas on students is illustrated by several school tests and the Lawson test, too. The significant part of this thesis deals with the teacher training in the Heureka project. The methods and forms used are described and the impact is analyzed. The international contacts and their development are mentioned in the closing chapter. Several more examples of materials both for students' work and teachers' seminars are published in the appendices. The DVD with digital recording of one lesson is also attached....

Experiential Learning in Physics Education
Kerepecká, Zuzana ; Koupilová, Zdeňka (advisor) ; Dvořáková, Irena (referee)
The thesis deals with using experiential learning in physics education. It begins with a review of the literature concerning this matter. The text is then focused on organizing longer events (i. e. events consisting of more individual activities) where experiential learning is used. The ideal process of planning such an event is described and attention is also paid to so-called "dramaturgy"; i. e. a way of choosing individual activities and arranging them. Two new activities for physics education based on experiential learning are offered (puzzle hunt with LEDs and doing a short scene about a life of a physicist) and instructions for making a teaching aid; that all focussed on physics. Furthermore, one activity proposed in the author's bachelor thesis (consisting of observing a night sky) was tested with students. The main part of this thesis describes the planning, realisation, and reflection of a two-day event organised for the purpose of this thesis. Experiential learning was used for teaching physics and the description of this event shows an application of theoretical principles in practice. Above all; the event might have positively influenced students' attitude towards physics thanks to experiential learning. 1

Application of Experiential Learning in Teaching Physics
Horálková, Zuzana ; Koupilová, Zdeňka (advisor) ; Dvořáková, Irena (referee)
The thesis deals with the method of experiential learning and its applications in teaching physics. Experiential learning is regarded as one of the possibilities how to accomplish educational goals. The first part of the thesis constitutes a reflection on the meaning of education, it offers, among others, a reason for discovering more about experiential learning. Furthermore, the theoretical background of experiential learning is described - Kolb's cycle and learning styles derived from it form a significant part; the growth zone is also presented. Attention is also paid to how the teacher and student are viewed in experiential learning. After the theoretical introduction, the thesis is more practical. It explains what a teacher has to know when creating and presenting an activity for students. This is followed by specific suggestions of activities which use the method of experiential learning and which are to be realised mainly outside the classroom (e.g. at an overnight school trip). The activities deal with different topics of physics (e.g. optics, acoustics or astrophysics). Students' own involvement and experience are emphasised. Suggested activities can supplement ordinary school teaching and thus let students know physics from a different perspective. 1
