Grading usually involves different ways he can come up with an excuse to take points off and he will take major points off for things that have nothing to do with the actual content of your work. In short, he’s a bully and a Dance Teacher. The College students he teaches want to be math and science teachers (a few elementary) so I think there is some jealousy there. A Dance teacher (even choir, theatre or band) would find it difficult to do the assignments. The assignments and papers, etc are geared toward content knowledge and teaching an academic subject.
I will add that Dr Hines does show favoritism to a few students and I am sure they are not graded so harshly.
