Did your neighbor tell the administration that if the child cannot be moved to another Math class she will be leaving the school? While that might not affect them so much this year, b/c the money from the state may have already been distributed, it should make an effect next year. I have to say it would be extreme to leave a school over one teacher and her teaching methods .... changing schools can be traumatic I'd suppose, but having that as leverage might make a difference.
I might consider talking to the principal and if he's resistant, going a step farther and contacting the board of education about the problems ... including the names and phone numbers of other concerned parents!
I cannot even imagine how discouraged the student must be and how angry the parents must be ... to have a child do all the homework and pass the tests ... how could you NOT pass the class??? Is their a glitch in the grading program? Even if you don't pass a test or two, that still shouldn't add up to a failing grade.
I know that once a teacher reaches tenure a lot of difficulty comes into play in making changes, but if schools are in the business of educating students and if said teacher isn't on board with the same goals, then the school needs to institute either changes with the teacher or options of change for the student.
If the teacher isn't making the cut and the kids need extra help, isn't it the school's responsibility to help close the learning gap? Oh man! I better jump off the soapbox! (I guess I am feeling grateful that our son that goes to school in the 11th grade now, has not had any major issues in school!)
And, hey, there is also the old adage, "Kill 'em with kindness." If the teacher plays favorites, why not play the game and become a 'favorite'. While it's not "RIGHT" to have favorite students, I guess that is part of life, right?
