If you want to improve your teaching practice, then why not give a training session for teachers? It is the best way to improve your teaching techniques and will give you the confidence to speak in front of other professionals. It is also a great opportunity to develop new ideas and build up a range of teaching ideas. You also don't need to give a talk, I would encourage you to attend conferences and workshops as this will improve your teaching awareness.
What was the last workshop you gave or attended? What did you learn from this? Are you planning on improving your teaching awareness? How do you plan to achieve that? Some questions to consider. As ever, don't forget to leave a comment and share some of your experiences as well!
