More A's, More Fails: What AI Is Really Doing to Student Performance

What happens when AI helps students earn more A grades, and also contributes to more failures when it's taken away? In this episode, Ray and Dan explore new research on AI's impact on student performance, assessment integrity, and learning. They discuss studies linking AI to rising grades, the risks of over-reliance on AI, and growing evidence that AI tutors may support learning better than general-purpose chatbots. The conversation also covers AI detectors, AI humanisers, teacher workload, Microsoft's latest Copilot updates, and a new tool for measuring the environmental footprint of AI use.
