Have you ever felt like you stunk as a teacher? I have 18 years experience and recently I felt this way. One of my colleagues came for a visit. He gave me some tips afterwards and pointed out some things that I should know better about! I was embarrassed (but glad he pointed these things out).
I took a good look in the mirror and immediately implemented some changes. Rehearsals have been more efficient and productive. These were things I knew – I had even implemented them and taught others to – but I had let things slide gradually.
Hope this reminder helps you as much as it has me.
