I am not aware of anyone who has really cracked the progressive yse of AI for teachers, especially in PBL.
It should be perfectly possible for learners to collaborate online and then collect data around individual contribution to give teachers insight. To do that for non-tech projects requires someone to capture contributions in the classroom. Could that be a mix of teachers, assistants, peer learning? Could it be visual recognition? Could it be audio files followed by speech to text and then text pattern recognition?
Clearly it is all possible. We just need the innovation.
