Teaching is not based on expertise. It is based on the love and passion for teaching. To make students understand, a teacher need not be an expert. He/she has to come down to the level of the learner and then taken the student to a higher level through knowledge and understanding. It should be like "Iron grip in a velvet glove."

I would suggest it is more to do with you understanding or conception of teaching and its development than actual time spent teaching. I could show you a teacher making the same fundamental mistakes for 20 years and a novice teacher with a relatively good grasp of teaching, although I admit improving on this does take time. I think Akerlind (2007) 'Constraints on adacemic's potential for development' can provide a good perspective on this.

Thank you Brett! I agree with you. However, having in mind those novice teachers with good potential to improve their teaching through time, don't you think there is a specific time, I'd say years, that are necessary go through until they manage to reach high levels of teaching efficacy? If so, in your experience how many years are necessary to achieve that level of efficacy?

It is an old thread, but I hope you have discovered by yourself by now what it takes to be a good teacher. You just have to start teaching and you'll know the answers to it.

I think teaching experience does not depend on years but on the ability of the teacher to develop himself
