Everyday AI (EdAI) addresses the need to develop a diverse workforce with the knowledge and skills to work with AI and answers the call for widely-accessible and age-appropriate AI Literacy education. Broadening participation in AI is important in ensuring that AI technologies are founded on principles of inclusivity and equitability. MIT and Boston College prepared over 120 middle and high school teachers from districts across Florida, Illinois, New York, Virginia, and New Mexico who tengaged over 4800 middle and high school students in AI lessons and activities that built students’ interest in AI and AI-enabled industries of the future. The majority of the students are from Black and Latinx families. EdAI was built upon the Developing AI Literacy (DAILy) curriculum that interweaves AI concepts, ethics in AI, generative AI, and AI career and futures. The EdAI professional development (PD) program takes a multi-pronged approach offering an AI Book Club, a Summer Practicum, and an online Community of Practice. Our research investigates how this PD model supports teachers to learn, adopt, modify, and teach the DAILy curriculum in a wide range of classroom settings and how the teachers’ implementation of the curriculum impacts student learning. Over the past 1.5 years, through US Dept. of Education funding, EdAI has partnered with New Mexico State University to scale the project across New Mexico and study its impact on Rural, Hispanic, and Indigenous communities.
