Another in the series of "really long voice notes from Staś". My friend Guy is a lecturer in natural language processing. He asked me if I could give him some tips about how to lecture better, so I told him I would record a podcast episode about it. I've divided the episode into two parts. In this first part, before we speak about practical things to do, I will discuss what the basic aims are, and some important preliminary framing questions - what are we trying to achieve? How does learning work? And when can I stop punching the ground with my fist? There is some extra pressure when talking about how to be a good lecturer, as in effect I might ironically give a bad lecture about how to lecture well. I think I did ok. Enjoy the episode. *** You can support Education Bookcast and join the community forum by going to https://www.buymeacoffee.com/edubookcast.
