Conservative Teaching

I am currently enrolled in elementary praxis, and I'm having difficulties figuring out what I am allowed to do and what I am not. I feel like this is the time for me to experiment with how I teach, but on the other hand I am scared to go outside my CT's boundaries. The teacher is really great, and I LOVE working with the kids, but I find that I am almost holding back. Does anyone else feel that way? So, basically I know we just talked about how many teachers are "conservative" and stay in there ways, and now I'm realizing why it can be so easy to do that. It is hard to take risks, but I guess ultimately if you never take them then you will never know. I am observing that my teacher for the most part does stick with the "Western" / "Folk" ways, in her teaching methods. The students take to it well, and still have fun with the lesson, but I can't help to think that if we incorporated more "popular music" or honored their world more, that maybe they would be even MORE involved. I don't know, but I was just wondering if any of you feel the same way. Do you think that we are ever going to fully move on from the "conservative" ways?
