From the NSDA Events page:
"Debate involves an individual or a team of students working to effectively convince a judge that their side of a resolution or topic is, as a general principle, more valid. Students in debate come to thoroughly understand both sides of an issue, having researched each extensively, and learn to think critically about every argument that could be made on each side."
