The global phenomenon that is Lean In has recently expanded to reach younger and younger audiences. A second edition of the blockbuster book, Lean In For Graduates, adds material directed to recent grads starting their careers. And, as the Ban Bossy campaign demonstrated earlier this year, the message of leadership and ending bias toward women resonates with school-age girls too.

That has proven true for a group of 13 sixth graders at Bronx Writing Academy, who signed up for a “Lean In – Girl Power” apprenticeship as part of their expanded learning day. Under the guidance of volunteers from Facebook, they studied issues that women face and used the book as a jumping-off point.

After ten weeks of eye-opening conversations and mentoring, they had an unusual opportunity to share their solutions with a symbol of female empowerment: Lean In author Sheryl Sandberg herself!

Facebook strategist and lead volunteer Kirstin Frazell brought her students to Facebook’s New York office for their final presentation, and turned on the projector to reveal Sandberg via video conference in Palo Alto. Sandberg listened to the thoughtful and passionate reports from each student, and applauded them for tuning in to inequities even as they start envisioning their careers.

"I'm so glad that you are spending time thinking about this,” she said. “The world’s still not equal. It’s still not equal based on gender, it’s not equal based on race. We don’t give the same opportunities to everyone.”

The afternoon video chat was the culmination of a semester-long volunteer project that Frazell and fellow Facebook volunteers Eunice Jin, Katherine Thomas and Emma Zaretsky embarked on through Citizen Schools, which partners with Bronx Writing Academy and 31 other middle schools across the country to provide apprenticeships in a variety of subjects.

The team of Facebook volunteers traveled to the Bronx once a week to teach these students a course they designed with AmeriCorps member Maddie Oliver, who is serving a two-year Teaching Fellowship with Citizen Schools. "I was so excited with how involved the girls got, and how passionate they got about women's issues at their age,” said Frazell. “I wish I had had that."

Their curriculum gave the students the opportunity to study four issues that women face: the gender pay gap, the media's presentation of women and lack of female role models, stereotypes, and gender policing. Each girl kept a journal, and their final project was to present an issue, share how it affects her, and propose a solution to address it.  The audience included their peers, teachers, and Facebook employees—including Facebook’s famous COO.

"We have to teach our girls that they can reach as high as humanly possible,” quoted Ebony, one of Frazell’s apprentices. "Beyoncé said that, because we cannot let young girls get held back by stereotyping. This matters to me because boys tell me I can’t play basketball because I’m a girl. This makes me feel useless and like I can’t do what boys can do. This is wrong because that’s hurtful and I need to know I can accomplish anything."

Iesha’s presentation emphasized hope. "I believe that equality is possible,” she read.” Men and women are being treated differently, and we can change that. The gender pay gap matters to me because when I get older and become a teacher, I want to be paid the same, as well as treated the same, as the men in my job."

"The most important thing that needs to happen is a great education,” Sandberg told the group. “So for all of you in Citizen Schools, the most important thing we can do to prepare you for your future is to make sure you have a great education, great teachers, and opportunities to do projects like this."

The Facebook volunteers not only provided their students with a chance to learn about the discrimination that they will likely face as they pursue their goals. They also embodied one of the solutions, by serving as successful female mentors themselves. Frazell, Jin, Thomas, Zarestky, and Sandberg are living examples of what female empowerment looks like in the modern workplace.

“You build these lasting relationships with the students and they start to see you as mentors, not just teachers,” reflected Frazell. “I think that’s really important as they’re going through their educational journey.”
