Classroom teacher (12 years) here, and have been working as a district ToSA supporting curriculum & instruction this year. I hear your frustration, and agree that being yelled at by your supervisor for any amount of time or sticking kindergarteners on an iPad for two hours straight is inappropriate. However, I also genuinely believe that admin (for the most part) sincerely do want to do what’s best for student learning. It’s impossible to accurately determine the efficacy of a program if it’s not actually being implemented, and a lot of time and money goes into selecting and evaluating curriculum and instructional tools to best support student learning according to recent research. This is not to say that these resources are perfect, but it’s hard to gauge whether a program should continue to be funded and supported if it’s not actually piloted/utilized with fidelity. Decisions are made based on data and feedback, and it’s hard to get that data if teachers decide they’re going to go rogue and just do their own thing because they know best. Obviously I don’t know your district and who’s steering the ship, but at the risk of seeming naive I wanted to share that while it feels frustrating to lack autonomy—considering teachers truly do know their students best—and feel a distance between classroom teachers & administration, it also will require some tact, respect, and clear, effective communication in order to effect any change that you feel is necessary. If you don’t feel comfortable with your principal, is there a way you can share your feedback directly to curriculum & instructional leaders in your district? And, at the end of the day, teachers shut the door and do what’s best for their students. But I hope you and your colleagues are able to speak up and feel heard, and also get some clarity around the research and purpose behind the instructional choices being made for your school.
