S04E02 - David Didau on Five Things Teachers Should Stop Doing
Sat Feb 07 2026
Have you ever taught a "perfect" lesson where every student got the answer right, only to find they remembered absolutely nothing the next day? In this episode, education author David Didau joins me to reveal why what looks like learning is often just a "performance"—and how our best intentions might be fueling the illusion.
We dig into five common teaching habits you need to stop immediately, including why "Sat Nav teaching" is creating dependency rather than independence and why the popular idea of "productive struggle" might actually be setting your students up to fail. David challenges deep-seated beliefs about practice, compliance, and memory, offering a provocative look at what it really takes to make learning stick.
