The tech industry’s campaign to embed artificial intelligence chatbots in classrooms is accelerating.

The American Federation of Teachers, the second-largest U.S. teachers’ union, said on Tuesday that it would start an A.I. training hub for educators with $23 million in funding from three leading chatbot makers: Microsoft, OpenAI and Anthropic.

The union said it planned to open the National Academy for A.I. Instruction in New York City, starting with hands-on workshops for teachers this fall on how to use A.I. tools for tasks like generating lesson plans.

Randi Weingarten, president of the American Federation of Teachers, said the A.I. academy was inspired by other unions, like the United Brotherhood of Carpenters, that have worked with industry partners to set up high-tech training centers.

The New York hub will be “an innovative new training space where school staff and teachers will learn not just about how A.I. works, but how to use it wisely, safely and ethically,” Ms. Weingarten said in an interview. “It will be a place where tech developers and educators can talk with each other, not past each other.”

The industry funding is part of a drive by U.S. tech companies to reshape education with generative A.I. chatbots. These tools, like OpenAI’s ChatGPT and Microsoft’s Copilot, can produce humanlike essays, research summaries and class quizzes.
