Electricity and magnetism: Hands-on minds-on approach
Koudelková, Věra ; Dvořák, Leoš (advisor) ; Kireš, Marián (referee) ; Richterek, Lukáš (referee)
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...

Precipitation processes in light hardenable alloys and the possibilities for integrating thermal analysis into physics education on high school
Kodetová, Veronika ; Vlach, Martin (advisor) ; Černošková, Eva (referee) ; Svoboda, Pavel (referee)
The doctoral thesis is divided into two parts - Thermal analysis in physics education on high school and Material research of Al-Zn-Mg(-Cu-Sc-Zr) alloys. Within the first part, the areas of crystallization and/or melting of selected foods were determined using differential scanning calorimetry. A practical lesson for high school physics has been created and tested. The study text focused mainly on differential scanning calorimetry and its use was made. In the second part of the doctoral thesis, there was analysed thermal evolution of the phase transformation in the Al- Zn-Mg(-Cu) alloys with Sc and Zr addition. The effect of (cold and hot) deformation on the decomposition sequences was studied. The hardening effect after annealing above 300 řC in the Sc and Zr alloys is caused by the precipitation of the secondary Al3Sc,Zr) particles. These particles were observed by transmission electron microscopy after annealing up to 360 řC in all studied AlZnMg(Cu)ScZr alloys. In the AlZnMgCu alloy the partial recrystallization was observed after annealing at 350 řC/10 hours and after annealing at 450 řC/10 hours the grain size was 50-200 m (depending on the treatment of the alloy). The addition of Sc, Zr in the AlZnMgCuScZr stabilizes grains and there is no recrystallization in the AlZnMgCuScZr alloy at temperature...

Dialogic teaching in physics education
Otáhalová, Klára ; Kekule, Martina (advisor) ; Mandíková, Dana (referee)
This bachelor thesis deals with dialogical approach in physics teaching. In communication between teacher and pupil, we can explore communication approaches, discourse patterns, and teacher questions. In the thesis, an analysis of the recordings of the lessons (own, virtual observation) is created. Four communication approaches have been identified as well as their combinations. Feedback was created for two teachers and typical patterns of their teaching were identified (eg: D / I, A / I combination). The work also includes a summary of the use of communication approaches by all observed teachers. At the end of the thesis, a material proposal for the students of physics teaching for the acquaintance with dialogical teaching is created. Keywords: dialogic teaching, physics education

Physics education as a part of leisure time activities
Brynych, Miroslav ; Žák, Vojtěch (advisor) ; Mandíková, Dana (referee)
This diploma thesis is focused on the support of educational leisure time organizations, which deal with science education, but not in the first place. Within the diploma thesis a literature search for non-formal science education was conducted and seven activities with supporting materials for the purpose to educate the participants of these activities as well as the organizers of them were created. The activities were prepared in such way to respect the fact that their organizer did not typically study science at university. The supporting materials should facilitate the preparation, carrying out and evaluation of the activity. All activities were verified in practice at meetings of the leisure time organization Junák - český skaut, z. s. The purpose of this verification was to find out whether and how the activities could be used in practice. Structured interviews with organizers and observation wre used to receive feedback. The final form of the supporting materials of particular activities is presented in the diploma thesis.

Physics problems for development of various cognitive operations
Kürtiová, Alica ; Žák, Vojtěch (advisor) ; Kekule, Martina (referee)
This thesis deals with the role of physics problems which help to develop various cognitive operations. Mainly the taxonomy of the learning tasks by Tollingerová and the Bloom's taxonomy of educational objectives have been used for this purpose. A material which contains characteristics of eleven chosen cognitive operations (induction, deduction, transformation, proving, abstraction etc.) and two typical learning tasks to each cognitive operation has been elaborated in this thesis. The material was created to guide and simplify the selection and creation of physics problems whose solution supports the development of cognitive operations. This process can inter alia help to define, fill and check required educational goals. It may also help with student's motivation or the development of key competencies. Keywords: learning task, physics problem, cognitive operation, cognitive process, taxonomy by Tollingerová
