U Penn TA criticized for race and gender-based preferences in engaging students

Article here. Excerpt:

'A University of Pennsylvania teaching assistant is under heavy fire after they tweeted that they would call on 'white men' last when doing student participation.

Stephanie McKellop, a Ph.D. student studying marriage and family (using them, they pronouns), has since set their tweets to private but shared that they were trying to encourage classroom participation by minority students.

'I will always call on my Black women students first. Other POC get second tier priority. [White Women] come next. And, if I have to, white men,' they said in the tweets on Monday.

In subsequent post, McKellop explains that the tactic - called progressive stacking - was one learned from a professor in undergrad.

'In normal life, who has the easiest time speaking, most opportunities? Flip it,' they added.

'The classroom is the place YOU get to control social setting.'

McKellop would continue to tweet about the reaction they were receiving for teaching the method and added: 'Penn thinks I'm racist and discriminatory towards my students for using a very well worn pedagogical tactic which includes calling on [people of color].''
