A couple of years ago, I took part in an intensive Spanish weekend workshop held at a local community centre in Manchester. On the second morning, when everyone was feeling a bit sluggish, the tutor introduced an exercise called 'speed-debating', which completely energised the whole room.
The premise was fairly straightforward. We were paired up and given silly, light-hearted topics to debate, things like whether pineapple belongs on pizza or whether cats are better companions than dogs. We had precisely two minutes per round to defend an assigned viewpoint entirely in Spanish. As soon as a timer went off, we had to rotate to a new partner and tackle a completely different topic, often switching between arguing for and against the same silly proposition.
I did this alongside roughly a dozen other learners, ranging from university students to retirees. At the start, most of us were quite hesitant because our grammar was far from polished, but the fast pace meant nobody had time to feel self-conscious. It forced us to think on our feet and draw on whatever vocabulary we could muster, often resorting to comical gestures when we got stuck for words.
I think what made it so enjoyable was the lack of pressure. Traditional language classes can be a bit dry, focusing heavily on rote learning and formal grammar drills. This game, on the other hand, shifted the focus entirely to spontaneous communication. Everyone was laughing so much that the fear of making mistakes just evaporated, which gave my spoken fluency a massive boost.
