4. G & T Debate Format

5. Lincoln-Douglas debate
A Lincoln-Douglas debate is one of the most popular types of debates in high school debate competitions. 
It gets its name from the Lincoln-Douglas Debates of 1858, which were a series of debates between Abraham Lincoln (Republican) and Stephen Douglas (Democrat) as they fought each other over a seat to represent Illinois in the U.S. Senate. 
The major issue of these debates was slavery. 

6. L-D Debate continued
More specifically, the debates focused on whether new states should make slavery legal or illegal.  Douglas favored the idea of “popular sovereignty,” or leaving it up to the states to make their own decisions about whether or not to allow slavery.  Lincoln, on the other hand, who was a staunch abolitionist, thought that slavery should be outlawed in the new states simply on the grounds that slavery was morally wrong.
In other words, Lincoln defended himself with a value. Today, competitive Lincoln-Douglas debates are also called “value debates” because they are about moral issues, human rights, and philosophical matters.  

7. Preparing arguments
Each team should prepare a list of at least five arguments.  Remember, an argument is just a reason for supporting your side, and reasons should always be supported by facts and evidence.  Each argument should be approximately one-paragraph in length. 

8. Writing the constructive
The constructive is your opening statement.  It is a short speech that identifies and briefly describes each of your very best arguments.  Keep in mind that there is a three-minute time limit when delivering your constructive. 

9. Prepare for cross-examination, refutes, and rebuttals.
  A good debate team always anticipates the opponents’ arguments.  Knowing what your opponent might say helps you prepare a list of cross-examination questions, points to refute, and rebuttals to use during the debate. 
You won’t have enough time to think quickly enough on the fly, so it’s crucial you bring good notes with you to the debate. 
Good notes include (a) pre-written constructive, (b) summaries of affirmative and negative arguments, (b) list of cross-examination questions, and (d) lists of quotes, facts, statistics, evidence, examples, etc.
