This is an interesting subject. Thanks for starting it Nicola.
I've been teaching people in one form or another for nigh on thirty years. But only since I went to college and got some proper teaching qualifications (and the resultant training) have I been able to apply my skills to enthuse and impart information much more successfully.
I have a holistic view to teaching, whatever the subject and I include not just the subject matter, scheme of work, lesson plans, aims and objectives and all the other 'teachspeak' stuff, but at the core of the teaching is the student. The whole thing is geared around the student, their aims and ambitions (what they want to get out of it), their abilities, their learning speed and their particular way of working stuff out.
So, there's no one way to teach I've found, especially in diverse groups or individuals. Most of my teaching is done around woodcraft, or more recently woodcraft with bushcraft skills introduced as a more environmentally friendly way of working with green wood.
Every one is different, and everyone works at a different pace. Some know more than others when they start a course, and everyone works at a different intellectual level, so in order to impart the relevant information it's important to be able to work with people at many levels.
Even with a class of ten students, I work more one to one with them after the initial briefings and introductions, and I treat each as an individual so knowledge and understanding of a subject can take place. Once knowledge and understanding happens, practice brings competence and that's what I'm aiming to achieve in any student.
I always create a very relaxed atmosphere in which to work, and the kettle is always on the simmer.
On a personal learning journey, I started as self taught through books from the library. After I got the teaching qualifications (I was teaching IT and Business Admin at the time), I decided to formalise my green woodcraft skills and did the NCFE course in green woodcraft with Maurice Pyle at the Flint Mill at Beamish. That was an eye opener and I learned loads from Maurice. So I applied what I knew from him, what I'd learned by trial and error on my own, and my teaching methods and took it from there.
