Schedule

TimeEdit

Course literature

List all mandatory literature, including descriptions of how to access the texts (e.g. Cremona, Chalmers Library, links).

Also list reference literature, further reading, and other non-mandatory texts.

Course design

Description of the course's learning activities; how they are implemented and how they are connected. This is the student's guide to navigating the course. Do not forget to give the student advice on how to learn as much as possible based on the pedagogy you have chosen. Often, you may need to emphasize concrete things like how often they should enter the learning space on the learning platform, how different issues are shared between supervisors, etc.

  • exervises
  • laboratory work
  • projects
  • supervision
  • feedback
  • seminars

Do not forget to describe any resources that students need to use, such as lab equipment, studios, workshops, physical or digital materials.

You should be clear how missed deadlines and revisions are handled.
