Logic and Reasoning

Logic and Argumentation provides students with the essential tools for clear thinking and effective communication. This topic covers the structure of arguments, focusing on how premises lead to conclusions. Students learn to evaluate the validity and soundness of what they hear in the media, politics, and daily life. This aligns with NCCA standards regarding the construction of arguments and the Junior Cycle emphasis on literacy and digital media literacy.

Mock Trial: The Fallacy Detective

Students are given a set of 'guilty' statements containing common fallacies like Ad Hominem or Slippery Slope. In a courtroom setting, 'prosecutors' must identify the fallacy while 'defenders' try to explain why the logic might actually hold up in a specific context.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • An argument is just a heated disagreement or a fight.

    In philosophy, an argument is a set of reasons given to support a conclusion. Using 'silent debates' on paper helps students focus on the logical structure rather than the emotional volume of the exchange.

  • If the conclusion is true, the argument must be good.

    An argument can have a true conclusion but flawed logic (invalidity). Peer-teaching exercises where students create 'broken' arguments for 'true' statements help them see the importance of the logical path taken.
