This is the second of four online modules within the CASLu programme. The module consists of 12 recorded lectures, each 60 minutes long. Participants will need to view each lecture and do the 5 hours of additional reading which has been provided by the lecturers. There is a mandatory evaluation at the end of each lecture. A Q&A area is available for participants who want to ask a question to the lecturer. At the end of the module, the participants will have to take a module test before being able to proceed to the next modules and eventually the final exam.
