I wonder if anyone has thought of the child's perspective on this? I recently asked a group of (12 year old) children what they think about having older teachers and without exception they all acknowledged that 'old' teachers have a lot of experience, but they said they prefer to be taught by teachers who are 'young' and have more energy and are more in touch with their generation. I suspect that 'A' level students may have given a different answer as knowledge and experience may be valued over (perceived) youth and enthusiasm. In one of the schools I worked there was a teacher who had taught many of his pupils' parents and the children in his class all thought that he was absolutely ancient. Of course he was only in his fifties at the time.
