Define what a rebuttal is to students. Have a written definition typed up for distribution to all students. Read the definition out loud and have all students use their own words to write a sentence or two explaining the reasons why a rebuttal is an important element of effective communications. Allow students to ask questions to help each one explain the definition clearly based on individual skill levels.
Show a video of a debate, such as a presidential debate. Make sure to run through the entire video which shows the moderator of the debate allowing opposing parties to enter in to a rebuttal response in regards to statements and opinions. Make sure to pause the video before the other party begins the rebuttal to point out to students that this is the point where a rebuttal fits in to a debate or discussion.
Have students write reviews about the debate they just watched. Make sure each student lists the pros and cons associated with each candidate or participants rebuttal and the effectiveness of the response. For example, remind students to pay attention to tactics such as staying on topic, remaining calm during the rebuttal delivery, having a strong voice and backing up rebuttal claims with facts, figures and clearly defined data.
Give students a list of debatable topic ideas. Divide the classroom up in to teams. Make sure for each topic and team, you have clear instructions which team is for or against an issue about the topic. For example, the topic of women in combat. Have one team take the position for women in the military fighting in an active war. Have the other team take the stance against the practice. Allow teams to prepare thoughts and remarks before beginning discussions. Have the "pro" team go first, followed by the "against" team which is using the rebuttal techniques learned prior. Have the first side --- the "pro / for" side --- then launch a rebuttal to the opposition's remarks.
Take notes regarding the rebuttal skills of all students and teams as a whole. Discuss with the class ways to strength rebuttal skills. View additional debate or discussion footage illustrating rebuttal tactics and delivery methods.
