Hi, I'm curious if anyone here would agree/disagree with this... I work at a school, where more than one teacher, has called on me to not teach things because it is something they (themselves) teach. Preface: IMO, these teachers are good teachers. I don't think they are bad teachers. But I've done a few things over the last few years, that they tell me that they don't want me to be teaching (my students move on to them). A few of them: not using school bought STEM materials "meant" for the upper grades (even though I teach "upper" grade myself 3rd). I did a Rube Goldberg unit in summer school--was told that it is part of 4th grade science and that I shouldn't teach it. I was told by 4th that we should run any Native American learning by them... I don't think they are trying to pick a fight or anything... and I am typically thick skinned when it comes to this sort of thing. i.e. If I learned that a teacher in a lower grade was teaching something I was planning on doing, I find that fine and dandy. I think doing it again will help them understand and apply even more. But honestly, this (to me) is nonsense and has me thinking of just leaving the school and moving to another. However, in doing so, I just wonder if this is something that is common of teachers... the idea that teachers have their "things", and that I would encounter the same issue if I went elsewhere.
