Teaching Methods (additional text)

The course will be offered both as an ordinary campus course and in a flexible way to off-campus students. Lecture notes, e-lectures and other types of e-learning material will be offered through Fronter. Communication between the teachers and the students, and among the students, will be facilitated by Fronter.

Form(s) of Assessment

Portfolio Assessment
Oral exam, individually

Form(s) of Assessment (additional text)

  • Portfolio (counts 40%)
  • Oral, individual exam (counts 60%)
