Inside the latest AI in education research: tutors, bias, and impact

This week's episode dives into a wave of new research shaping how AI is actually being used in education. We explore what works (and what doesn't) when it comes to AI-generated feedback, including why blended, "hybrid" feedback may be the most effective approach - and why more feedback doesn't always lead to better outcomes. The conversation then turns to one of the most important emerging issues: bias in AI systems. From subtle differences in tone to stereotyping based on student characteristics, the research highlights why educators need to be cautious about the data they provide AI tools. "If you use AI to write feedback, it does not treat every student the same way equally." We also talk about the growing evidence around AI tutors - where they outperform humans, where they fall short, and what actually drives meaningful learning gains. Along the way, we tackle major questions around detection, student use, teacher workload, and whether AI can ever replace human connection. The big takeaway? AI is powerful. And how we design, guide, and use it in education matters more than ever.
