Teaching and learning methods

Teaching methods in lectures and exercises: Lecture-style instructions mainly on the blackboard. Explanations and exemplifications are supplemented by computer-aided presentations. The presentation slides will be made available for students via download on Moodle. In solving relevant exercises a deeper knowledge of the subject-matters presented in the lectures is sought. Exercises will start approximately in the third week of the course and are enrolled within the course. Exercises are provided with the objective that the students first should solve the problems independent by themselves at home. The solutions to the problems will be demonstrated in subsequent exercise sessions, and will be available via download on Moodle.

Recommended literature

References will be presented in the first lecture hours.
