These questions are so important. I spoke with some lecturers last week who think that accreditation has gone totally overboard in the UK, and I can see where this concern is coming from - I think sometimes assessment and evaluation are so top heavy in the UK that we spend extra time making sure that we look good for the quality control process instead of genuinely enhancing our teaching.
On the other hand, several of my students in our LTHE program (who are lecturers) have said emphatically, "I wish I knew this last year when I started teaching".
It's such an interesting question - how do we have some sort of standards for enhancing the quality of teaching, but not have an over-controling regulatory framework?
