Detecting Logical Fallacies, Part Two

Learn 13 more logical fallacies — and develop the skills, tools, and habits of stepping back, analyzing a situation, and thinking logically and clearly. Critical thinking is a must for all students!

Total classes: 12

Prerequisite: NONE, although Detecting Logical Fallacies, Part One or equivalent is highly encouraged

Suggested grade level: 7th to 9th grade. Mature 6th-grade or interested older High School students are also welcomed.

Suggested credit: One full semester Formal Logic

Special Notes: This is Part Two of a two-part course. New students can be accepted mid-year if there are available seats.


This course builds upon the skills and knowledge acquired in the course Detecting Logical Fallacies, Part One and the idea that middle school is a great time to introduce formal logic. Students continue the pursuit to combine the concrete with the abstract, utilizing a method that will lead them to further develop a habit of stepping back, analyzing a situation, and thinking logically. By cleverly completing this course, students will solidify their grasp of the first 15 concepts and then learn the details surrounding 13 additional fallacies. Detecting Logical Fallacies, Part Two will further your student’s ability to decipher, analyze, and contend with a complex world using a sound and logical approach.

This is the SAME book as Part One. This course will briefly review the first parts and then cover the last parts of this book in detail.

ONLINE: Join the Quizlet class for this course and utilize its sets on Quizlet.com (Free student accounts are available.) A link to join the specific Quizlet class for this course will be posted on Moodle.

Homework: Students will work on about two chapters per week. Parents should note that the answer key in the back of the textbook is for the students’ use to check themselves as practice for their weekly work and to prepare for the class discussions.

In addition to the Practice Questions using each Lesson of the book (self-evaluated and reported on Moodle), there are Quizlet Terms/Definitions and Tests: 4 Quizzes, a Mid-Term, and a Final Exam (all graded on Moodle).
