My son arrived home with barely held back tears this afternoon because he had to redo his homework.

I read through the questions and his answers and am puzzled. There were three questions on a two page chapter. The first two questions were essentially the same so in the second answer he explained that and then elaborated. The last question was also so obvious that he went beyond the answer and went into possible reasons behind the explanation in the text.

I don't understand how a teacher could mark this down. Could she not see that he understood and was over answering? Was it an exercise in following the rules or was it to determine understanding?

In any case, while it's not an important mark I feel I should discuss it with her. I hate conflict. Any advice? Empathy?

It's quite likely she was in literal mode while she was marking and perhaps didn't think about the person answering.

Thoughts? Feedback?
