I have been a substitute teacher throughout my credentialing program, and continue to after I graduated, so I have have been subbing a fair amount. I sub at a particular school where they have like a floating helper that goes to different classes to help out in the afternoon. I'm not sure if she's an instructional aide, or really what exactly her position is. She has come to the classrooms I am subbing in and basically rude and interrupting me during my lessons to the class, telling me I'm wrong about something during a lesson and correcting me (when I was not wrong), and just numerous other such things. I do admit the last time I had her in the classroom and she started in on this, I just offered her to continue the lesson since she just kept interrupting and undermining my authority to the students I personally felt. Today I had her in a classroom and she just took over a lesson without my asking, interrupted me several times during the lessons. To clarify, she was not teaching correctly what was to be taught for the lesson. Later when I gave Jolly Ranchers out as an incentive to students to keep on task she loudly blurted out that it wasn't allowed. I feel she could have just done this later or more discreetly. I will definitely ask the school offices from now if candy is allowed in the classrooms. I had been told as a student teacher that candy was always a good incentive, but I do understand the drive for healthy eating, and candy not being the best thing. At any rate, it was her loudly and rudely blurting out that it wasn't allowed that bothered me. Honestly, I think she's totally oblivious to how rude she is actually being, but nonetheless I personally feel this is quite rude what she is doing overall when in the classroom with me, and as a substitute teacher not sure what to do, as I feel I am a guest at these schools and just not my place to say much. I did end up mentioning this problem to a same grade level teacher who had started me out that morning, and coming in at breaks to kind of let me know what needed to happen next (things that weren't included in the lesson plan). I am normally very closed mouthed, and wonder if I should have said anything to the other teacher about the problem I was having with this woman in the classroom with me. What would some of all you do? What is the best way to handle this kind of situtation in some of your all's opinions?
