This short video created by my colleague Prof. Isabella Martini illustrates how to use the free software 'Screencast o matic" to videorecord a slide presentation. It can be used by all students but it is especially useful for students using MAC as a MAC doesn't give the option to videorecord your powerpoint presentation. Non-MAC users can use either, Screencast o matic or PowerPoint (Microsoft office 365 ProPlus version) which has the option to videorecord your slides directly, as I showed you in class.
