Planned learning activities and teaching methods

Teaching methods depend on the teaching methods are described in Article 7 of the Study and Examination Regulations of the University.
For teaching system is used LMS Moodle.
The lessons are organized field trips to companies manufacture composite materials - specifically excursion to Morfico firms, companies KrampeHarex CZ, companies Bachel and more.
The lessons are organized lectures of practitioners.

Assesment methods and criteria linked to learning outcomes

Credits are awarded based on attendance and submission of properly prepared reports of exercise. Attendance at seminars is required. Participation in the field trip is mandatory. Participation in professional lecture practitioners is required.
On each student is required to draw up a protocol. Each protocol is evaluated by the teacher.
The test includes a written part and an oral part. Student must pass part of written and oral.
