"Other than lectures and access to staff, what exactly are they getting for their £27,000?"
Well, first of all, I don't agree that lectures are a bad way of learning: I like to think that my lectures (which I spend many hours writing) are both stimulating and engaging.
But secondly, this is what my students are getting for their money, apart from their lectures:
weekly seminars to discuss the module topic in detail
a website which I update on a weekly basis, providing ample resources for the module and for further study
a further online teaching resource which I have designed myself and put many (unpaid) hours into
a weekly office hour when they are encouraged to drop in and see me
the offer (well advertised) to make appointment for meetings outside of office hour if they need to
extra 1: 1 meetings by appointment before and after every essay for support and feedback
prompt response to emails regarding course and/or personal issues
regular papers given by eminent scholars in the field which they are encouraged to attend
links with outside body which gives free access to further lectures by eminent scholars in the field at nearby location: this is advertised to students at the time
departmental presence of facebook and twitter, drawing attention to events and new developments in the field
a very well-stocked university library open 24/7 with working spaces and online resources
a Personal Academic Tutor for every student who will see them at least once per semester to check that everything is going all right and who will liaise and support them with any non-module related needs
a Pastoral Support Officer in every department who will be able to offer advice and liaise with appropriate support staff in case of any pastoral issues
a drop-in centre for SEN-related support
specially dedicated Literary Fellows to offer support with writing issues (by appointment)
carefully prepared: a) Faculty Handbook b) Subject Handbook c) Module Handbook.
Like other lecturers, I find that take-up is very varied and that it is usually the same students who take advantage of everything. The ones who complain about lack of contact hours are often, by some strange coincidence, the ones that didn't keep 1:1 appointments they had made themselves, who turned up to seminar without having prepared the text, and who don't check out the website for announcements.
I like students. I like teaching. But I do wish students who find it too much effort to turn up for a 9 o'clock Monday lecture or a 5 o'clock Friday seminar didn't complain about lack of contact. Because I jolly well do turn up- and spend months beforehand preparing.
