Teacher doesn't explain work til end of assignment, gives bad grades?

I'm taking an oceanography class in college, and recently got a 70 on a video report worksheet we did during class. I'm upset because the professor didn't explain at all how to fill out the report until the video was nearly over, after at least 15 students had to get up during the video to go whisper to him and ask how to fill it out. The worksheet had questions phrased like this: ';Reproduction: __________, Habitat:_______'; Etc etc. No one knew how to fill it out though because the video was about at least 4 animals, all with varying reproduction habits, habitats, etc. At the start of the video he said nothing, and said to just watch the video all the way thru, so I thought it would make sense at the end. It didn't, and most of the class, like me, ended up handing in half-done worksheets as a result of missing the instruction...the parts about the animals were over by the time he said to just pick one. Should I complain to him? If he refuses to change our grades is it possible to go above his head on this problem? This is not the first time.Teacher doesn't explain work til end of assignment, gives bad grades?
yes you can go over his head and report him and in the mean time front him a bout it and if he still does it you and the other students keep reporting him till some thing is done a bout it
