Teaching methodology
In the pre-arranged weekly lectures of the subject, the parts of the curriculum related to the individual research topic of the students are presented in the framework of a consultation, which helps to acquire comprehensive flow knowledge and to independently acquire parts related to the research area. Students are given an individual assignment related to their research topic during the semester, which they must solve during the semester and report on the outcome. During the solution of individual tasks, within the framework of the lectures or beyond that, consultation is possible.

| End of validity: | 2029. July 15. |
General rules
During the semester, the student solves an independent task closely related to his / her own doctoral research topic. During the semester, the theoretical lectures give each student the theoretical knowledge and methodology needed to solve the problem. Students work independently on their own assignments, and the lecturer is regularly consulted as they progress. At the end of the semester, students present the results in front of each other and prepare a documentation. At the end of the semester, the result of the oral exam consists of the completion of the semester assignment and the quality of the presentation.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | formative assessment, project-based, complex | |
| Number: | 1 | |
| Purpose, description: | To be developed during the semester, a project task related to PhD research, which helps to deepen the acquisition of the curriculum through theoretical and practical calculations and derivations. The aim of the partial achievement is to examine the existence of knowledge, ability, attitude, and learning outcomes belonging to the autonomy and responsibility competence group. Upon successful completion of the task, the student stabilizes the knowledge acquired in the lectures. | |
Detailed description of assessments performed during the examination period
Elements of the exam:
| Written partial exam | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | In the written exam, the lecturer gives three questions and / or calculation tasks from the syllabus given during the semester, which the students develop independently in writing over a given period of 120 minutes. No aids may be used during development. A sample set of questions and a collection of possible written exam questions compiled on the basis of the curriculum are available to the students. The questions asked of the students serve to check the appropriate level of mastery of the curriculum. The prerequisite for the oral exam is a successful written exam result, so the success of the written exam is a prerequisite for the oral exam. | |
| Oral partial exam | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | In the oral exam, the speaker asks three questions from the curriculum, to which the students answer in detail at the board after a few minutes of reflection time. No aids may be used during the preparation period. The questions asked of the students serve to check the appropriate level of mastery of the curriculum. A prerequisite for the oral exam is a successful written exam result. The oral exam must be particularly successful. | |
