Most schools are now off for winter break — but this year, some educators are wondering how much their students are learning. A KPMG survey found that over half of Canadians over 18 years old now use generative AI to complete their school work. Professors and students are concerned that a growing reliance on tools like ChatGPT and Gemini could be weakening critical thinking skills. Recent research is now giving us further insight into that potential connection. The Globe’s Joe Castaldo reports on AI and tech. He tells us what educators and students say about how generative AI is impacting schools and what recent studies tell us about its effect on our collective critical thinking skills.
