Dopey Logic
IB Maths Studies Logic Argument Truth Tables

Description/Aim




The 'legalise it' debate is one that is regularly in the news these days. What are your views? What arguments do you back your views up with? In this activity, you can debate this with your class, survey yourself and your class (can be done online with google docs) and analyse the logical soundness of your arguments!

Teachers Notes - Why? How? What?

Why we like this activity ….

Topical context brings engagement with it! All you need is a good debate before we start looking at the
holes in eachothers arguments. 'Logical Analysis' follows neatly from the debate

How this activity be used ….

Debate followed by questionnaire! I really reccomend the use of googledocs for the questionnaire. (I
am working on a way to provide a ready made googledoc, but am not there yet, but it does not take
long to make). Afterwards, students need to think about this activity individually.

What to expect when using this activity – from our experience

Lively debate that naturally leads to the logic issues at hand! The transfer from words to symbols needs
to be handled carefully.
