Debate is a valuable way to practise communicating. It can also bring long-lasting rewards, especially for people working with Western businesses. The main activity of debate is presenting one's opinion and supporting it with evidence, such as statistics or facts. It is a way of persuasive communication.

　　Charles Lebeau helped create the "Discover Debate" method. He says debate is important to understanding how people communicate in Western business. Successful debaters learn how to give their opinion, reasons and support. "What we are trying to do is to develop a kind of thinking or approach to discussion and how to interact（交流）with someone else's opinion, rather than brush their opinion aside."

　　Debate skills are also important in selling a product, he says. In that situation, the judges are the customers. "So on Monday, for example, one company may come in and present their case to the customer and they'll make as strong a case as they can. On Tuesday, the next day, another company will come in and present their case to the customer. Usually the party that can present the strongest case wins."

　　Debate also strengthens critical thinking. In other words, it helps students learn to ask questions and try to understand someone's reasons and evidence.

　　Mr. Lebeau points out that successful debaters learn to listen carefully to what other people are saying. Then, they look for the weak points in someone else's opinion or argument. He says debate teaches a systematic way of questioning.

　　Successful debaters also learn to think from someone else's point of view. Mr. Lebeau says debate can help broaden the mind. "There's an expression in English: don't criticize another person before you have walked in their shoes. I think the wonderful thing about debate is, it puts us in another person's shoes."
