About Those First Quizzes
September 27, 2012Posted by on
Your first collaborative quiz consisted of one prompt:
Explain the limitations of a deductive argument; then explain the limitations of an inductive argument.
Note the word limitations, which implies a measured consideration of strengths and weaknesses; limits throw both into relief, and your answer should have made mention of what each type of argument does well. These two concepts are the bricks and mortar of logical fallacies.
Scores for this quiz will be posted online after a decision is made about curves and weight. Check the Resources page for Infinite Campus login information. The key to the quiz is below.
Let’s start with a verbatim excerpt from page ten:
That last paragraph should have been unpacked in your response; a few details from elsewhere in the chapter on premises and conclusions, and you’d have been fine. As for induction:
You should have paraphrased those ideas and linked them to the rest of the chapter’s focus on relevant background beliefs and reliable information sources. Without all of that—a sense of the above two excerpts, plus clear links to background beliefs and reliable sources—you could not have written an effective quiz response. The closer you came, the more points you earned; if your group did not come close, you have a score that reflects that.
The message for many of you: You cannot build on a weak foundation. You must now revisit this chapter and review its main ideas again. Give yourself tonight—Thursday—to do that, so that we can begin to forge ahead. More quizzes are coming.
Edit: On second glance, the two biggest weaknesses in these responses are (1) a lack of development, which leads to vague and ambiguous reasoning on your part, and (2) imprecise language, e.g., the use of “true,” “valid,” and “accurate” interchangeably.
