This type of online course attempts to capture some of the flavour of a typical WEA course where the participants all meet uo on a weekly basis and interact with the tutor and between themselves. It is not a one-way transmission of a recorded lecture similar to what you would view on BBC Four.
In order to participate you would need a PC, Mac, laptop or tablet with a webcam and microphone, preferably built-in. You would also need a connection to broadband via cable or Wi-Fi. A broadband speed of 3Mbps would be adequate. The system, which is called “Zoom” is similar to Skype.
There are various guides to using Zoom:
