How to present elements of Special Theory of Relativity
Soukup, Marek ; Dvořák, Leoš (advisor) ; Gottwald, Stanislav (referee)
The core of this work are electronic tools, specifically interactive animations, usable for teaching the special theory of relativity in the advanced courses in the high schools and on college level. Using HTML5 technologies were created four interactive animations and calculator of relativistic phenomena. For interactive animations, there are sets of questions and tasks accompanied with the correct answers. There are three options in using of these tools: either by the teacher in frontal instruction method or by students during their individual work or by the general public interested in the topic of the special theory of relativity. Whole package is available online. The work also includes research of related literature, misconceptions and available electronic tools. Powered by TCPDF (www.tcpdf.org)

Physics education of students and teachers in Heureka project
Dvořáková, Irena ; Dvořák, Leoš (advisor) ; Trna, Josef (referee) ; Lapitková, Viera (referee)
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....

Experiments in Mechanics for Future Physics Teachers
Urban, Martin ; Dvořák, Leoš (advisor) ; Kácovský, Petr (referee)
The aim of the thesis was to select and verify experiments with simple aids for utilization in the Mechanics or Theoretical Mechanics lecture for future physics teachers. We deal with a selected area of experiments, which is body rolling. In particular, rolling balls at an inclined slat of an L-profile and in the groove between two rails, the distance of which being adjustable. For these cases, the acceleration of the balls is derived in several different ways, both by neglecting the rolling resistance and by including the rolling resistance. In the experiments, the movement of the balls was recorded on video and analysed using the Tracker program. The accelerations of the balls obtained from the processed measurements are compared with the theoretical results. It is shown that with small inclinations of the inclined plane (which is suitable for the demonstrations because the moment of the balls is more visible), it is necessary to take into account the effect of the rolling resistance.

Pendulum not only from the high school point of view
Chamrová, Martina ; Dvořák, Leoš (advisor) ; Žák, Vojtěch (referee)
The diploma thesis is divided into five chapters. The first chapter is devoted to the history and usage of pendulums with focus on the development of measurement of time and gravitational acceleration. The second chapter deals with the concept of pendulum from a theoretical perspective at all levels of the Czech educational system, including a research in textbooks, collection of questions and problems, and scientific articles. In the third chapter, the results of the research of sources of inspiration for simple real- life experiments, applets and simulations, and laboratory work are presented. The fourth chapter is focused on the theoretical background of the four selected models of pendulums, and the last chapter is devoted to simple experiments with these selected models. For each experiment, a videorecording is available on the enclosed DVD. This thesis is suitable for all physics teachers, as well as for students of teaching physics. However, it may also serve as a motivation for students in optional courses of high school physics. 1

Electricity and magnetism: Hands-on minds-on approach
Koudelková, Věra ; Dvořák, Leoš (advisor)
Title: Electricity and magnetism: Hands-on minds-on approach Author: Věra Koudelková Department: Department of Physics Education Supervisor: Doc. RNDr. Leoš Dvořák, CSc., KDF Abstract: The PhD. thesis is focused on high school students' understanding of electricity and magnetism and on experiments which can help students to develop this understanding. The thesis can be divided into two parts: In the first research part typical misconceptions of high school students in the area of electricity and magnetism are described, both misconceptions known from foreign literature and results of Czech Conceptual Test of Electricity and Magnetism. This test is based on the known Conceptual Survey of Electricity and Magnetism, but unlike it and other conceptual tests in electricity and magnetism this new Czech test is intended for high school students. The second part of the thesis is developmental. It contains methodical materials, lab works and experiments which partly arise from the discovered misconceptions. In this part of the work four learning sequences (we chose topics, which were identified as problematic for students), four laboratory works and 13 experiments are described. Prepared materials were verified during instructions in high school and during conferences for physics teachers. Experiences with them are...

Practical Electroacoustics in Physics Education
Matouš, Otakar ; Žilavý, Peter (advisor) ; Dvořák, Leoš (referee)
v anglickém jazyce The subject of the presented work is (the usage of) electroacoustic transducers in physics teaching. Its first part contains an overview of study materials, physics textbooks and a selection of academic studies dealing with the aforementioned topic. The central part of the thesis consists of three experimental activities in which electroacoustic transducers are employed. These activities may be adopted for home or laboratory work of students or in hobby groups. The first activity aims at exploring the principle of operation of or- dinary headphones. The second activity contains instructions for making a simple phone. The third, most extensive activity, focuses on the measurement of electrical properties of various electroacoustic transducers. The results are further used for a more detailed discussion of their operating principles. In the final part of the thesis, the usage and verification of one of these proposed activities in practice are discussed.
