In January, Sesame Workshop and the International Rescue Committee will start work on what they're calling "the largest childhood intervention in the history of humanitarian response." Funded by a $100 million grant from the MacArthur Foundation, the project aims to reach 9.4 million Syrian refugees and local children in Jordan, Lebanon, Iraq and Syria through a new, regional version of Sesame Street and related activities.

The show will be distributed via television, the internet and mobile phones, with related content given to childcare centers, to clinics and directly into the hands of parents and other caregivers in their homes.

Sherrie Westin, Sesame Workshop's executive vice president of global impact and philanthropy, spoke to NPR's Ari Shapiro about the program. Here are highlights from the interview, which has been edited for length and clarity.

On reaching a refugee audience:

Penetration of both TV and mobile in Syria and Jordan is huge, and that surprises people who don't fully understand that the largest number of refugees aren't in camps but in regular neighborhoods. We're able to reach children together with their new neighbors.

On adapting Sesame Street for a refugee audience:

Literacy, numeracy and the social-emotional skills that build resilience are somewhat universal. What makes the content most impactful for children in developing countries and places of conflict is that it's developed locally. The basic model is what Sesame Street has done for almost 50 years but making sure it's more reflective of their reality is what makes it so special.

I can certainly imagine there will be a character who had to leave their home or who lives in a tent or becomes best friends with their new neighbor. For instance, in Afghanistan the lead Muppet is a little girl named Zari. Girls' education is a real issue in Afghanistan. She wears her hijab with her uniform.

On reaching children and parents at home:

A home visitor meets with a caregiver, training them on the most important way to help a child overcome trauma. There's so much proven science on this — that adult-child engagement is the most important thing. It's called nurturing care. It may sound intuitive, but when parents have been through this kind of situation they are very stressed themselves. We give them techniques and tools and strategies to help their children overcome the toxic stress — games, content, storybooks, apps, all sorts of things — but also an understanding of the importance of that nurturing care.
