08. Logic in Debate

Objectives

‍

1. Understand the main mechanics that determine the logical interaction of arguments, examples, rebuttals,… in debate
2. Use understanding of debate mechanics to construct effective arguments and rebuttals in debate
3. Learn to evaluate the logical strength of different arguments to judge different arguments presented for ideas 

‍

Learning outcomes

‍

The application of this lesson is twofold:

1. Primarily, to engage effectively in public discourse
   
   1. Teaching students how to construct concise arguments with coherent logical links equips them to express their opinions clearly and persuasively. This skill enables them to use their voice effectively, promoting their ideas and contributing to higher-quality discussions in public discourse.
2. Secondarily, to critically evaluate public discourse
   
   1. Understanding the logic behind arguments and discussions helps students assess the validity of others’ reasoning. By identifying flaws, gaps, or unfair argumentative tactics, they develop the ability to distinguish strong arguments from weak or deceptive ones. This awareness empowers them to engage thoughtfully in modern discourse and resist misleading rhetoric.

Timeline:

1. 10minutes – Introduction
2. 20minutes – Argument Mechanics
3. 30minutes – Constructing Arguments and Rebuttals
4. 20minutes – Evaluating Logical Strength
5. 10minutes – Debrief 

‍

1. Introduction
   
   1. Ask question to class: What makes an argument convincing
   2. Introduce key ideas: “Argument”, “Premise”, “Example”, “Impact”
   3. Run through an example of an argument (see Material Document for an example)
      ‍
2. Argument Mechanics
   
   1. Small group (3-4student) discussions on prompt “We should ban homework”
      
      1. Students are tasked with deciding on one argument on the topic with an example and after to find rebuttals against this argument 
   2. Then regroup: Discuss what people came up with
      
      1. Teacher assists the class by adding explanations on the functioning of arguments and on logical fallacies 
         ‍
3. Constructing Arguments and Rebuttals
   
   1. Set a prompt (f.e. We should have an age restriction on social media) and assign every student either to pro or contra
   2. Student has 10 minutes to write an argument
   3. Student paired with another student from another side (contra if student is pro) and they present arguments to each other and try to rebut them (10 minutes)
   4. Last 10 minutes – regroup in class and discuss what made certain arguments more or less convincing/ what made an argument vulnerable to rebuttals
      ‍
4. Evaluating Logical Strength
   
   1. Present class with a couple of arguments on one subject with different properties, some with ad-hominem fallacies, some with false dichotomy, some logically sound, … (see material document)
   2. Discuss with class what arguments one finds persuasive and what not – why is this the case?
   3. Create a scoring rubric for arguments that evaluate different metrics essential for a good argument (clear premises, clear impacts, …) (see material document)
   4. Apply the scoring rubric to exercise from the previous section
      ‍
5. Debrief 
   
   1. Discuss what the class learned about the key terms discussed in the introduction
   2. Ask students to write a short statement explaining what they learned today that makes them better at making arguments in the future

‍

Assessment

‍

1. Written argumentative essay on a prompt
2. Prepared speech on predefined argument
3. In class Debate
4. NOTE: Rubric presented in materials can be used here

‍

Tips and tricks

‍

1. Adapt the subjects of the discussion to topics close and relevant to the students

For Introduction

‍

1. Class Demonstration of an Argument:
   
   1. For example: Topic - We should ban social media
   2. Argument: Social Media leads to addiction and is bad for the health
      
      1. Thesis: Social media is addicting and bad for the health
      2. Premise 1: Social Media is addicting
         
         1. Social Media uses the concept of endless content that has to be explored and an addicting algorithm that means that users often feel like they have to use social media and feel the urge to check social media to not feel like they are missing anything
      3. Premise 2: This is bad for ones health
         
         1. People spend more time indoors when on social media, their eyes get strained, they move less – all of which means people are less fit and in less good health which might lead to negative long-term consequences
      4. Conclusion:
         
         1. We saw that social media is likely addicting and likely bad for the users health – for this reason we should ban social media to protect a society wide health epidemic

For Logical Strenght Part

‍

1. 4 arguments on the topic “We should have school uniforms”
   
   1. Pro
      
      1. If we don’t introduce school uniforms, students will either dress inappropriately or waste all their time worrying about fashion trends. Without uniforms, classrooms will be full of distractions—students comparing brands, commenting on outfits, or even bullying others for wearing ‘uncool’ clothes. The only solution to this chaos is enforcing a uniform policy, which guarantees students dress appropriately and focus on learning instead of their appearances. By implementing uniforms, we eliminate these distractions and create an environment where education takes priority.
         
         1. Issue: False dichotomy - Presents only two extreme options while ignoring other possibilities like a dress code that allows personal expression while maintaining standards.
      2. School uniforms create a sense of equality among students by removing visible indicators of socioeconomic differences. Without brand-name clothes or trendy outfits, students focus more on academics and collaboration rather than comparing appearances. For example, studies from schools that adopted uniforms reported a 15% reduction in bullying incidents related to clothing. By fostering a more inclusive environment, uniforms contribute to better academic outcomes and stronger peer relationships.
         
         1. Good example of argument!
   2. Contra
      
      1. Many leading psychologists, such as Dr. Jane Smith and Professor Klaus Müller, agree that school uniforms suppress individuality and creativity in children. For instance, Dr. Smith has argued that children express themselves through clothing, which is an important part of their development. Similarly, Professor Müller has noted that forcing students to conform to a single standard of dress can hinder their ability to develop a sense of self. Since experts who study child development advocate against uniforms, schools should avoid implementing them.
         
         1. Appeal to authority fallacy: Argument relies too heavily on expert figures to legitimise the ideas without giving any actual reasons for why this ought to be true
      2. In some schools, the introduction of uniforms has shown no benefits for discipline or academic performance. For example, when the Wilhelm-Gymnasium in Hamburg adopted uniforms, their reports showed no measurable change in bullying rates or test scores over three years. Furthermore, students expressed dissatisfaction, claiming that uniforms made them feel controlled and restricted in their personal choices. These findings demonstrate that uniforms are ineffective in achieving their intended goals and may even harm student morale.
         
         1. Cherry picking fallacy: Picked one specific example and extrapolated a generaliseability to everyone else without justifying this
