11:21 AM PT -- Professor Anthony Cook, who also teaches law at Georgetown, says Sellers needs to "wake up" and realize why her comments promote white supremacy.
Cook says Sellers needs to understand that her feelings towards Black students only perpetuate stereotypes.
If she ever teaches again, Cook hopes Sellers changes her techniques to try and get the most out of her Black students.
10:43 AM PT -- Dean Treanor says he's terminated Professor Sellers after further review of the incident. He says during his conversation with her, she told him she intended to resign, but either way ... Sellers is "no longer affiliated with Georgetown Law."
As for Professor Batson, the dean says he's been placed on administrative leave pending an investigation by the school's Office of Diversity, Equity and Affirmative Action.
Treanor adds ... "We are taking significant steps to ensure that all students in this class are fairly graded without the input of Professor Sellers or Professor Batson."
A law professor at Georgetown University is under fire for comments she made about Black students doing poorly in her class ... with some calling her racist and demanding she be fired.
Ya gotta see the video ... the professor is discussing student performance when she says, "I end up having this angst every semester that a lot of my lower ones are Blacks. Happens almost every semester."
The Georgetown Black Law Students Association says the professor is Sandra Sellers ... and the organization says she should be fired for "blatant and shameless racism."
The BLSA also says Sellers was talking about a Black student when she said their answers were "a bit jumbled." The org says David Batson is the other professor in the video seen nodding in agreement.
GU says it's investigating and law school dean Bill Treanor says the video is "abhorrent" and "reprehensible."
