I heard this term for the first time during CELTA when we had an input session on TBL (Task-Based Learning). To be honest, I didn’t really understand what it was and how to use it (neither of us did, really). Next time I heard about ‘Deep End’ was during training at my current workplace. It sounded somewhat familiar. I went through an imaginary CELTA folder in my head trying to get a tiny bit of information but failed. It didn’t really ring a bell. The only thing I could remember was the observation video of Jane Comyns-Carr teaching a lesson on Past Perfect using TBL approach, and there was something about ‘Weak End’ and ‘Deep End’, too.
So what is ‘Deep End’?!
