Planned learning activities and teaching methods

The course uses teaching methods in form of Lecture - 2 teaching hours per week, seminars - 2 teaching hours per week. The other activities - 2 teaching hours per week for Practicum of Chemical Engineering. The e-learning system (LMS Moodle) is available to teachers and students.

Assesment methods and criteria linked to learning outcomes

Graded course-unit credit system. The student evaluation depends on the active attendance and the correctly solved separate numerical set of theoretical exerceces. The exam consists of the numerical part and the oral examination, studens have to show basic theoretical, numerical and practical knowledge in the branch. The use of defined literature materials in the numerical part of exem are allowed.
