I did not go to university at 18 but a Teacher Training College. We had lectures & seminars on philosophy & history of education as well as pedagogy. In addition we had to study a 'curriculum' course too. I studied Dance & Drama This had to be both at our own academic level as well as to learn how to deliver it as a curriculum subject in school. It was three years of interesting academic work as well as practical as we had to have so many weeks in the classroom too. We also grew up! In my case I was in London, in digs. Independence, managing budgets laundry etc. etc. plus negotiating relationships, sharing accommodation, work schedules and so on are all part of HE life and equally important, imo to the academic side.
The broadening of HE, to include degrees in less traditional university subjects has, for some, de-valued degrees.
This all harps back to our incredibly snobby attitude to academic ability vs practical ability. I do believe it is good to study, at the highest levels we are capable of, just for the pleasure of learning and not solely to gain employment though of course that is useful! We need all sorts of people, with all kinds of abilities, to make the world go round. I know some wonderfully useful people who left school at 16 but have made a huge contribution to society and some very useless twazzocks with doctorates! Judge not on the qualification but on the the actions and application! Sadly stupid computerised systems of recruitment are probably created by the twazzocks!
