ENG 4U 2013: Day 1 Induction/Deduction

The purpose of this course is to make you a better communicator. We will closely examine the methods through which great communicators like Shakespeare convey emotion, thought, and action; we will often use their work as inspiration for our own.  Because we need to prepare you for the post-secondary world, we will also consider the sort of communication that occurs in university and college.

Let’s start with a quick prezi: http://prezi.com/feurk8ljmqcm/untitled-prezi/?auth_key=864b9fe4ef84da5a2edeed465fd3cfe1e3ea0d74&kw=view-feurk8ljmqcm&rc=ref-4948609D

Next, let’s take a look at this video about sexism in the Super Bowl. We will return to this video near the end of the class.

Deductive and Inductive Reasoning

Reasoning usually takes one of two forms: induction or deduction.  The process for these two forms of logic looks something like this:

DEDUCTION

(Usually reduces from the general to the specific. Deduction eliminates possibilities)

General Theory                                         Specific Case                               Conclusion

Education is an important component of success. You want to succeed. You should get an education.

INDUCTION

(Induction increases possibilities. It often results in a general principle)

Observation                     Pattern                              Hypothesis                            Theory

All Grade 9 students in my   homeroom were in uniform on the first day of school. All Grade 9 students   observed throughout the school were in uniform, while senior students were   not. Grade nine students were in   uniform because they were proud of their new clothes; because the senior   students’ uniforms were old, seniors felt uncomfortable wearing them. After further   investigation, we have come to the following:Compliance to the school   uniform is based on students’ perception of rules and the consequences for   breaking them.

FAULTY DEDUCTION….but why?

Christianity holds that three equals one Three does not equal one. Christianity is false.
Jesus is the Word of God The Bible is the Word of God Jesus is the Bible.

FAULTY INDUCTION….but why?

My daughters have pink   clothes and pink toys. Most young girls have pink   clothes and pink toys; boys, however, don’t. Most girls like pink. After numerous observations,   we have come to the following theory: interest in colour is   determined at the chromosomal level.

Complete the following with a partner. Both partners must write the responses:

  1. Write one example for each of the following: deduction, induction, faulty deduction, and faulty induction.
  2. Choose one subject you have studied repeatedly. Given the nature of the assignments you’ve completed in that subject, which form of reasoning does that subject rely on the most?
  3. What kind of reasoning did you use to complete the last question? Why?

Tonight, please read The Closing of The American Mind on page 325 of your text or an article of your choice from the Atlantic. By Wednesday, you need to write a 1 page response in which you:

  • Identify and explain one example of the author’s reasoning (consider mapping out the reasoning using the structure outlined above).
  • Agree or disagree with the writer’s reasoning (if you disagree, try pointing the error in the reasoning itself)
  • Provide detailed examples that support your view of the writer’s work.

This will also help me identify the strengths of your writing. I will respond to your work by the end of the week.
