#### Learning and Teaching Methods

Lecture and large tutorial are held in ex-cathedra teaching, the exercises are given as interactive teaching (calculation of examples). The optional questioning hour e.g. after the lecture is of major support for students for questions on the study topics as well as organisational questions.

In the large tutorial relevant examples for problems are presented.

The tutorial is held in small groups. The students not only learn to reproduce the presented solution of the problems but also train to solve problems independently. For this exercise sheets are offered. The students prepare these problems on their own or in small groups. This helps them to deepen their understanding of the new methods and concepts. In the tutorial the weekly exercises are presented by the students and the tutor. They also provide room for discussions and additional explanations to the lectures.

#### Media

Animated powerpoint presentation with figures of relevant physical devices and processes. Complicated matter (e.g. deduction of formulas) is written on a tablet PC into the ppt file and projected. Many experiments are shown.

### Module Exam

#### Description of exams and course work

There will be a written exam of 90 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.

For example an assignment in the exam might be:

- Determine the total moment of force acting on a given construction.
- Determine the point of detachment for a point mass sliding down a sphere.
- Calculate the deflection angle of a perpendicular within an aeroplane due to the Coriolis force.
- Calculate the moment of inertia for an object rotating around a given axis.
- Sketch a p-V-diagram of a thermodynamic cyclic process and calculate the work/energy in each cycle.

Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.

#### Exam Repetition

The exam may be repeated at the end of the semester.
