A teaching team of two (at least) is what teaching requires in 2020. Digital changes everything, whether online or off, as soon as it goes on a screen it has to compete for the 'attention of eyeballs'. Not only that, it isn't a cliché that 'two heads are better than one'. Advertisers know that it takes a write and an art director to create a compelling idea. For something compelling to work online it need the write, visualiser and coder. A team of three might be asking for too much, but the point remains.
How many people does it take to create a module of online learning at the Open University? The figure is more than one. Why therefore are teachers and tutors expected to do everything themselves?
