I had a call with another mom today who also has a straight-A student. She's a very active mom, communicates with other parents, and advocates for our kids. We were chatting about our class teacher's birthday – the kids want to surprise her tomorrow. And then we got talking. It turns out at least half the class is failing history and Russian. Several moms have already tried to contact the teacher about these subjects. At home, the kids can practically recite the chapter by heart, but at school, they're getting C's and D's. The teacher doesn't explain anything and scrolls on her phone while a student answers. This happens every lesson. She assigns reading a chapter for homework and then randomly calls on students during class. I personally approached her and asked her to call on me so I could improve my grade, which is a C. She ignores raised hands and requests. The Russian teacher corrects the letter 'o' to 'o', meaning she marks the correct spelling as incorrect (according to other parents). If a paper gets an A, she doesn't record it in the grade book, only giving C's and D's. The class teacher ignores parents, doesn't respond to messages or calls. You can't get into the school without a pass from her. By the end of the first quarter, we won't have any straight-A students left, even though parents are checking their kids' work at home. Some people say kids should go to school for knowledge, not grades. But grades aren't just given out arbitrarily; bad grades (especially unjustified ones) kill the desire to learn. And some teachers don't teach anything at all. Is it possible that the entire class suddenly became stupid in two subjects? That just doesn't happen, right? These two teachers are new, this is their first year teaching after finishing their own studies. What steps can we take to at least meet with the teachers, especially if the class teacher is ignoring parents? The school website has the secretary's number – can I get a pass through them to enter the school?
