I'm not bashing teachers, I'm just looking for some thoughts on a situation with my DD.
DD is a junior, taking chemistry with Mrs. Smith, who is new to the school.
Comes home first day & says Mrs. Smith came from a city school & I think she might be a little tough. No big deal. A week later I ask how things are going with Mrs. Smith. Going good; she's OK; not DD's favorite, but not as tough as she thought. Seems to run hot & cold with her personality.
About 3 weeks in to school DD asks when one of the labs is due. Mrs. Smith says Friday. On Wednesday Mrs. Smith asks for the lab. DD reminds her she said it was due on Friday. Mrs. Smith says, "Oh well, my mistake, it was due today". DD turns it in & gets points off for it not being complete. DD is upset, but I told her when she asks a question maybe just ask if Mrs. Smith can write it down or sign a planner or something so it's confirmed in writing. Do better on next lab & get it done sooner than planned. Next day, however, Mrs. Smith apologizes & gives DD back the points she lost for incomplete work. Thank you Mrs. Smith.
Following week is open house. A very young Mrs. Smith proceeds to make this statement to parents, "When I went to college I could immediately tell which kids came from private school & who came from public. I am here to raise the bar for your public school children." What the heck does that mean?

Why do you say that to parents who have chosen to send their children to a good public school? OK...........whatever. Let me just say the teacher was extremely immature & did not win us over with her attitude.
Fast forward to today. DD has been staying after for extra help in Chem. Wasn't going to stay after today because Mrs. Smith went off on the class. No one has above an 80 average & that "disgusts her". She told them that the Atomic Theory takes most teachers 2 days to teach & she is "bored to tears" because it has taken her over a week to teach & the kids still aren't understanding it.
I guess one of the girls asked if there was another method she could use to teach it because they were having a hard time. Mrs. Smith didn't like that & according to DD (who I know is a dramatic teenage) said Mrs. Smith pretty much called the class stupid & dumb for not understanding what she was teaching.
Now, while I don't think the student should question a teacher's teaching methods, my first thought was also that maybe the teacher should change her method. I know when I'm trying to teach something (dance teacher), if the students are grasping it I have to change the way I'm teaching it.
I guess I'm wondering if all of this is worth even thinking about.
Thoughts................let it go...................speak with the teacher.............speak with DD's counselor & ask how DD should work with teacher when she is difficult?
I'm not looking to be flamed & hear that my DD needs to grow up. I'm just wondering what others think of this & if I'm reading too much in to it.
