Artificial intelligence (AI) has the potential to improve K-12 education in the United States. For students, AI can provide them a personalized learning experience tailored to their individual preferences and needs, immediate feedback on their work and answers to their questions, and increased access to tutoring and other educational materials. For teachers, it can help automate some of their workload, design better interventions, and reduce burnout. And for administrators, AI can monitor the student body and provide preemptive interventions with the help of predictive analytics. But while there are many benefits to AI in schools, there are a number of technical, operational, and social challenges that limit AI-driven innovation in the education sector. This report explores existing and potential uses of AI in K-12 education in the United States as well as the challenges that hinder the technology’s adoption and effectiveness.
