Hey, here are a few pointers to improve your debating skills.
1. Always think comparatively. Think about whether your argument is strong enough or too weak as every thing you say will be debated at the end.
2. Always act like your winning, (be confident) Composure, poise, ethos, whatever you want to call it is an essential skill in public speaking and in life in general. This does not mean be arrogant! Rather, it means that you should always display confidence in the arguments that your team is making.
3. And remember debating is a team activity. Even if you are stronger than your partner, you shouldn’t take over their speech or answer all of their questions in cross-examination. When that happens, your judge is more inclined to give both of the members lower speaker points, and one debater doesn’t learn the skills necessary to get better. Instead, make sure that you and your partner are going over arguments together so that you can teach each other the best arguments to make.
Hope these tips help you.
