Parliamentary debate offers something different. Instead of relying on research and authoritative sources, we learned to use other types of evidence including analogies, narratives, and persuasion. Instead of relying on speed, we began to count more on delivery. To a student, the most interesting and captivating thing that parliamentary debate offers is the fact that competition is available on the international level. Nothing can compare with the excitement of being able to compete with the world's best debaters.
Worlds offer something that no nationals can compete with.
Debate occurs on a broader basis. Instead of domestic issues, students are forced to focus on the world, with something other than modeling disadvantages and which country has more nuclear weapons. Instead, students must focus on the culture and the background of the host country. It allows you to apply what you have learned in your classes into debate, instead of the other way around. Instead of spending hours upon hours cutting cards, parliamentary debate forces you to look at what is happening now in the real world.
