One school is using a traffic light metaphor to explain when students can use AI for their assignments. Chatbots took many schools by surprise upon their release a few years ago. Suddenly, students carried an app in their phones that could magically answer almost any homework question or spin up an essay in seconds. Of course, teachers can often tell when a student is using AI--models make mistakes that most humans don't, and some teachers say that AI-generated text has simple giveaways like too many em dashes . Nevertheless, the generative AI boom increased the burden on teachers, who were already working long hours to plan lessons, make homework assignments, and grade exams, and now needed to adapt to a new technology. For many, it still feels like there's no clear path forward.

Tim Ballaret once dreamed of becoming a stockbroker but ultimately found fulfillment helping high school students in south Los Angeles understand the relevance of math and science to their daily lives. But making engaging class materials is time-consuming, so this spring he started experimenting with generative AI tools. Recommendations by friends and influential teachers on social media led Ballaret to try MagicSchool, a tool for K-12 educators powered by OpenAI's text generation algorithms. He used it for tasks like creating math word problems that match his students' interests, like Taylor Swift and Minecraft, but the real test came when he used MagicSchool this summer to outline a year's worth of lesson plans for a new applied science and engineering class. "Taking back my summer helped me be more refreshed for a new school year," he says.
