Logical problem solving class #5 at Yokohama National University

Today’s topic was Inductive method, which is one of the two techniques to develop a logical argument.

While an induced conclusion may NOT be 100% logically correct, I shared two counter-solutions to this issue:

Depending on which type of the induction, you need to check either (i) whether there is no exception for Type 2 or (ii) a hidden assumption is valid for Type 1.

Type 1 has examples with the same subjects, while Type 2 has examples with the same predicates.

They are two cases for Type 1 &2. No one single right conclusion you can draw from the examples connected with the conclusion on the top of the structure.

Finally, in the class, six small groups developed some cases with inductive logic. But I found that it was hard for university students, who do not have any work experience nor problem-solving experience, to come up with some specific ideas about a conclusion to assert or issue to solve.

Some specific issue or assertion may need to be provided in advance so that they can come up with a logical structure to support the conclusion.
