Logical problem solving class #6 at Yokohama National University

Today, we conducted some exercises of developing a deductive argument with some GMAT questions.

Before doing those exercises, I shared three typical pitfalls of deductive argument so that the students can identify and notice the common errors in thier logic developments.

(1) Logic gap

You may have logic gap/jump between premise and conclusion.


(2) Feasibility error

Your premise(s) may not be feasible, which weakens your argument.


(3) Alternative paths/causes

If you ignore alternative way(s) to reach the conclusion, then your logic is weak.


I found that it was so important, especially at this beginning phase, for students to be more familier with the common form of logic structure and learn how to avoid those pitfalls.

Next week, we will do the same exercise for inductive arguments!
