Set realistic expectations
People have very high expectations of themselves, which is not a problem in and of itself. People frequently expect themselves to be specialists in all areas of teaching and learning, which becomes a difficulty for them. In actuality, people need hours of professional development (PD) or coaching in a specific area to improve their own skills and the learning of their pupils.
About 50 hours, to be exact. To be clear, if students want to improve their math instruction practice, they must commit to 50 hours of coaching and professional development. Recognizing that it will take time to feel strong and grounded in all of the areas that you want to as an educator is a part of addressing that judgment-filled voice within you.
