Re: The Open University provides 0365 and doesn't accept open document format
Well, I tutor on OU, and I think the default requirement is RTF format, which is pretty much lingua franca. It is not so much what the OU will accept, it is what the tutor can read. If all formats were accepted, then we would get all sort of obscure data files which we would have to translate and translate back.
The OU is generally pretty MS agnostic, but it also has to cater for a large diverse and generally computer illiterate body .and that applies to the tutors themselves, while you would hope software tutors are comfortable with computers, classics, history, etc tutors may not be.
A bigger problem is things like maths courses which require complex equations. Apart from forcing the use of LaTex, the OU is is forced to find tools that provide consistent results.
