Here’s yet another intro to mathematical thinking MOOC. Loughborough University, and in particular Professor Tony Croft, is offering a course called “Getting a grip on mathematical symbolism” through the FutureLearn platform. It starts on the 28th of April.
There isn’t much information about the course online yet, apart from the brief description on the official website and this AV-services-tastic trailer:
Since everything to do with popular maths has to pun (see also: literally any other page on this site), I can only assume that the course will end with the construction of a robotic hand or high-friction surface.
Tony Croft has a good pedigree with online learning resources: for many years he’s been in charge of maths support at Loughborough, including the invaluable mathcentre support site.
