ohhhhhh...good observation....never thought of that. But you may very well be correct. I could see that happening
It didn't happen to me, as my grades were very similar between quarters, but some teachers might do it.
Sounds paranoid. All throughout my schooling, I received the grade I worked for. There was only an exception with Art classes, in which when you try your best and it's not too clean, some teachers mark you down. But if you talk to other parents and they don't share your concern... it's just coincidental (and quite normal/natural) that your child improves over time. Heck, I would do much better near the end of a marking period when I would notice my grades were slipping. Very common in school kids.
I was not assuming everyone was treated fairly. *shrug* I haven't had all good experiences, and I know other people haven't either. That was just my initial reaction to the title question, because I see kids slack off in the beginning and then suddenly kick it into high gear a lot. They did it gradeschool all through college, never failed.
Also.... I am not assuming I know anything about your child. Your child was not even in the question (until now), so please do not feel the need to scold me about attacking you on that. I was just answering your question honestly with my own experiences, which is what all of us are doing here.
Its all a ruse to pretend children are learning something while they are being dumbed down and trained to be regimented surfs.
