Net Support Learning
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
Oral exam, individually
Form(s) of Assessment (additional text)
- Portfolio (counts 40%)
- Oral, individual exam (counts 60%)
- Both parts must be passed
The portfolio consists of up to 10 assignments and one project and is handed in individually. There is continuous assessment of each of the assignments before the final submission date of the portfolio. The portfolio will be given one single grade.
Alphabetical Scale, A(best) – F (fail)
Two internal examiners.
Re-sit examination of oral exam by appointment with the course responsible. No re-sit examination of the portfolio.
