論理的誤謬 - より良く考え、より良く推論し、より良く議論する...

Welcome to my class on Logical Fallacies! 

I taught this subject for many years at a public school and understanding this concept help my students be better thinkers, reason better, and write more persuasively.

Why is it important to learn about Logical Fallacies?

Because a logical fallacy is an error in reasoning that creates an invalid argument. And if you don't know that you're arguments are invalid, then you don't know if your arguments are going of track - or if your arguments are even good arguments!

In this class, I will share with the learner one logical fallacy a week (sometimes two, depending on the complexity of the fallacy).

We will start out each class with a quick overview of the fallacy with the teacher, then we will work in small groups to work through a few examples of each fallacy. After the small groups, we will come back together and walk through each example of the logical fallacy so that I can confirm that students understand the idea.

My style is to ask questions to help understanding rather than just give answers outright. Whether I'm teaching logical fallacies, law, or any other subject, I've found the act of questioning helps students clarify their understanding or confusion in their own minds, which allows them to gain clarity on the topic eventually.

Then it's off to the races - by which I mean I give them some more practice problems to cement their understanding. If there is time - depending on student questions and the need to clear up any confusion - we try to create our own examples of that week's logical fallacy and share it with the class through the Outschool classroom.

Depending on the speed we go through the one logical fallacy for the week, there will always be a backup fallacy so that we use our time completely each week.

No prior knowledge is needed, and you can slip into the classes at any time. If we do not finish all of the practice problems during a class, then an answer sheet or a video explaining the answers will be provided so that students can finish up on their own.

This is one of the subjects I started teaching as a high school teacher that really helped students learn to be better thinkers and spot arguments that others make that are fallacious in nature.
