Okay. Now we're dealing with proofs. The main idea behind a proof is that you are defending an argument through sound reasoning. Watch this video detailing the two types of reasoning we engage in when trying to evidence a proof. The video explains inductive and deductive reasoning.
Your Task:
1) Give an example of deductive reasoning with at least 3 steps (different, obviously from the video's example).
Here's mine:
a) All crows are black
b) The bird on my fence is a crow
c) Therefore, the bird on my fence is black
2) Then give an errant example of deductive reasoning, where there is a false conclusion.
Here's mine:
a) All Toyota cars are relatively fuel efficient
b) My car is relatively fuel efficient
c) Therefore, I drive a Toyota
Clearly, my reasoning is incorrect; I could drive a different relatively fuel efficient vehicle.
Now you go. The grade on this post is simple:
10 total points. 8 for actually posting, and 2 for commenting on another student's post as to whether you agree with his or her examples being deductive reasoning, and the errant example being indeed errant.
