I dont think chatbots like ChatGPT are productive for students at large. There is def an argument for high-performing students who understand how to use chatGPT productively but more importantly low-performing students struggle to get the most out of chatGPT due to bandwidth issues in the classroom. When I talk to teachers about AI in the classroom they prefer their students to stay as far away from chatGPT as they can because building a strong educational foundation with long lasting learning skills should come before using tools like ChatGPT. Once that foundation is there, generative AI tools are way more useful. In the classroom AI should be teacher facing, and not centralize around students and quick answers.
