Richard Carranza got schooled pushing his race-based agenda at a “Sesame Street”-sponsored event Tuesday.

The city schools chief was part of a forum assembled by The Sesame Workshop, a non-profit affiliated with the famed children’s TV show, which just issued a report about how racial, gender and other personal factors can fuel kids’ biases, as well as the prejudices they experience themselves.

Carranza — who has been accused of focusing on perceived racial disparities in the school system at the expense of education — noted that 82 percent of the city’s 1.1 million students are either black, Hispanic or Asian, yet 60 percent of their teachers are white.

“If you have a teaching force that doesn’t represent the students they are teaching, we should have a conversation as adults and professionals,” Carranza said at the forum, which was held at the Ford Foundation’s headquarters in Manhattan.

“What are the implicit biases? Not because we are biased, but then how are we coming to terms with that? How are we recognizing that? How do they manifest themselves in policies and processes that we have in our schools?”

But during a question-and-answer session later, audience member Ian Rowe, the black CEO of the city charter network Public Prep, challenged the claims put forth by Carranza and the rest of the panel.

“There will be lots of adults — both well-meaning adults and not well-meaning adults — that are looking to box you in to certain categories of identity,” Rowe said. “And our strong message to our kids is, ‘Do not let them. You have the power. You have the control.’

“So ultimately, what we are trying to develop is kids who have a sense of personal agency,” or ownership of their futures, he said.

Rowe, whose network teaches roughly 2,000 mostly minority kids in The Bronx and Lower East Side, said his schools have opted to emphasize identities more concerned with academic achievement.

“If you go into our schools and ask our kids, ‘What is your identity?’ they likely would not say any of those six categories,” Rowe said, referencing The Sesame Workshop report, which examined race and ethnicity, gender, religion, social class, country of origin and family makeup.

“They likely would say, ‘I’m a boys prep scholar,’ or, ‘I’m a girls prep scholar.’ We just did a spelling bee, and one of our boys won the spelling bee. So his identity now is the spelling-bee champion. One of our girls just competed in a chess competition and got to the finals. She would say, ‘I’m a chess player.’ ”

Rowe added that the report focused its analysis on the negative stereotyping and abuses kids are subjected to, rather than what measures are working.

“In our schools, if you were to go to any of our campuses, every student is greeted every morning by the principal with a very positive message,” he said. “Not necessarily about their identity, but, ‘Good morning, we’re happy to see you. Did you do your homework last night?’

“So I would be interested to see the study of how often kids are seeing positive impressions of who they are.”

Carranza and the rest of the panel did not react to Rowe’s comments.

The chancellor’s term has been mired in controversy over everything from lawsuits alleging that he promotes minority DOE workers over more qualified whites, to his push for new brand of curriculum to do away with instruction that focuses on “historically advantaged social/cultural groups.”

Another panelist argued that kids develop biases early on from a torrent of external influences and can be the victims of prejudice themselves — and that this needs to be combated.

Panelist Christia Spears Brown, a professor of developmental psychology at the University of Kentucky, said parents sometimes try to ignore the problem.

“We have to come to terms that kids aren’t color-blind,” she said of biases. “They aren’t gender-blind. They aren’t class-blind. And so instead of having a vacuum of all the biases, the stereotypes that barrage and pummel kids from left and right all the time, let’s have a conversation. Let’s replace all of those voices with our voices.”
