Teaching and learning methods
The module is composed of a lecture (3SWS) and a tutorial (1SWS). In the lecture the topics are presented using power point and blackboard.
In the tutorial concrete problems are solved and additional examples are treated.
Teaching method:
During the lectures students are instructed in a teacher-centered style.
The students are encouraged to read supporting literature and apply the discussed analytical and numerical methods on their own PC using MatLab.
The exercises are held in a student-centered way.
The following kinds of media are used:
- Presentations
- Lecture notes
- Exercises with solutions as download
