in class writting

In my Spanish three class all the students are very active and forced to learn and not wanting to be there. The class as a whole are always chatting to eachother but it's never about spanish class. The teacher always seems to be the one who brings up a topic that has nothing to do with class. Then the students get hyper and we stay off subject for a good ten minutes. My teacher has this policy if you don't participate then you lose points that count towards your overall grade. So if he calls on you by surprise you have to put some effort into it. If you don't know the answer he doesn't get mad but kind of looks dissapointed like if he wants to get out of class already. If any of students want to have a day where you dont want to pay attention you have no choice and are forced to listen or you have to get out. The way his system works and how you have to be paying attention all the time or your grade goes down it makes students not want to be there. Their learning goes down in a negative way and it just causes problems. That's three different areas of how it is in my Spanish three class.
