That is a very silly teacher indeed Les. It would not happen in my classroom. I encourage my kids to fight for every mark (1/2 marks included). It kind of goes like this. I write the test, they sit the test, I mark the test, they get it back. I go through the answers then we fight for fifty minutes over who got it right
. I love this part of the process as it shows the kids have a passion for the subject and have done their homework. If they can show me to be wrong (and they do) I award bonus points for the question. As for sylabus statements that are factually incorrect, they will be picked up and the relevent body notified to change it. You cannot teach a subject at the upper levels if you don't know your stuff and I have seen changes made to sylabus statements on a number of occassions as a result of complaints by teachers.
