Put here all relevant material for students

To do

  • Email to students with Zoom details
  • Be more specific about the way of grading (Niels)

Guidelines

Lecture format:

  • Divide each lecture in 2 (or 4) topics,
  • Ask the students to write lecture notes of 4-6 pages of a topic in groups of 3 students,
  • Derivation of equations in an appendix
  • A template of the lecture notes for each topic will be provided.

Exam:

  • Your written lecture notes
  • Each group takes lecture notes on 1 (or 2) topic(s) they were not involved in, and will present this in 15 minutes to the rest of the group.
  • Each group will get a total number of points which can be subdivided over the different students.


Groups

Groups of 3 students each to work on the assignments.

  • Group 1: Tjip, Leon, Alessia
  • Group 2: Marjolein, Barbara, Nigel, Niels
  • Group 3: Anastasis, João, Maricke
