This is the fourth of four online modules within the CASLu programme. The module consists of 21 recorded lectures and reading material provided by the speakers. Lectures valued at 1 unit provide a 30 minute recorded lecture and 2.5 hours’ of additional reading while those valued at 2 units provide a 60 minute recorded lecture and 5 hours’ of additional reading. 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 pass a module test before being able to proceed to the next modules and eventually the final exam.
