Educators are increasingly adopting AI tools like Claude to enhance various aspects of their professional responsibilities in higher education, ranging from creating course materials and conducting research to managing administrative tasks and personal learning. A detailed analysis of approximately 74,000 anonymized conversations and qualitative research from Northeastern University faculty reveals that AI is primarily used for curriculum development, academic research, and student performance assessment. While AI is employed for both augmentation and automation of tasks, educators tend to favor AI for automating routine administrative work, but remain involved in tasks requiring creativity and direct student interaction, such as lesson design and academic advising. Despite the convenience AI offers, educators express ethical concerns over fully automating grading, with many opting for AI as a collaborative thought partner rather than a substitute for their expertise. This evolving use of AI is prompting educators to rethink their teaching methods and content, aiming to adapt to new educational dynamics and maintain the quality of student learning experiences.
