Students whose teachers were given access to an AI teaching assistant felt less motivated to learn. “Instead of doing the actual work, they’re using AI to delegate the task, and that lowers the quality of their teaching.” “Here, I think teachers are potentially using AI as a material generating machine for homework, lecture notes, lesson plans, syllabus. Students whose teachers had access to the AI tool rated their classes as less enjoyable, less interesting and less important than students in the control group. One possible explanation for the weaker academic performance among students of low-performing teachers, Sungu said, is that stronger teachers treat AI output as a first draft, revising and adapting it to their classrooms.
