THE head of science at Bideford College, who had previously been a research scientist and nurse, will be retiring at the end of the school term.
Dr Nicola Farmer, 50, from Braunton, has been at the college for four years having been teaching for a total of nine years.
Prior to teaching she was a nurse and then was a research scientist at the University of Bristol.
Dr Farmer, who has been teaching chemistry at Bideford, said she was looking forward to spending more time with her family during her retirement.
She said: "I want to spend time with my family, and more time gardening and walking.
"It is very hard to choose the best moment I have had at the college, but I think when a child says 'thanks miss' as they leave my lab because they have enjoyed the lesson is just the best feeling in the world."
Dr Farmer also recalled one of her most embarrassing moments at the college.
She said: "Before we had the new college built, I was teaching in the old Abbotsham block. The teacher's desk area of the lab was on a raised plinth.
"On this particular day I was teaching Year 8. I was in full animated flow and didn't realise how close I was to the edge of said plinth.
"To my horror I caught my foot on the edge of this wretched plinth and fell head long off it, landing in a heap on the floor with my head pretty much in the waste paper bin. This was of course much to the amusement of my class who were by now in fits of hysterics."
