Propositional Logic and Truth Tables

<p><b>CONTENT</b>: This week we will teach you how such phrases as “and”, “or”, “if”, and “not” can work to guarantee the validity or invalidity of the deductive arguments in which they occur. It will also teach you to understand the functioning of these phrases using a device called a “truth-table”, which shows how the truth or falsity of propositions that use these phrases depends upon the truth or falsity of the propositions contained within it. We highly recommend that you practice the skills that you will learn in this week by doing the puzzles at betapuzzle.sonjara.com.</p><p><b>LEARNING OUTCOMES</b>: By the end of this week’s material you will be able to :<ul><li>define what a deductive argument is</li><li>define what it is for a deductive argument to be valid</li><li>identify truth-functional operators and connectives</li><li>build a truth-table for any truth-functional operator or connective</li></ul></p><p><b>OPTIONAL READING</b>: If you want more examples or more detailed discussions of these topics, we recommend <em>Understanding Arguments, Ninth Edition</em>, Chapter 6. </p>...

Categorical Logic and Syllogisms

<p><b>CONTENT</b>: This week will teach you how such phrases as “all”, “some”, and “none” can work to guarantee the validity or invalidity of the deductive arguments in which they occur. It will also teach you to understand the functioning of these phrases using a device called a “Venn Diagram”, which shows how the truth or falsity of propositions that use these phrases depends upon the truth or falsity of other propositions that use these phrases. We highly recommend that you practice the skills that you will learn in this week by doing the puzzles at http://philgames-neta.apps.unc.edu</p><p><b>LEARNING OUTCOMES</b>: By the end of this week’s material you will be able to : <ul><li>understand the information conveyed by a truth-table</li><li>use truth-tables to determine whether a deductive argument is valid</li><li>identify quantifiers and categories</li><li>build a Venn Diagram for any statement using quantifiers or categories</li></ul><p><b>OPTIONAL READING</b>: If you want more examples or more detailed discussions of these topics, we recommend <em>Understanding Arguments</em>, Ninth Edition, Chapter 7. </p>...

Representing Information

<p><b>CONTENT</b>: This week we will teach you how to use the tools that you’ve learned about in the preceding modules in order to represent information. Information can be communicated in very different ways – by means of different languages or signaling systems – but no matter how that information is communicated, it can be important to use that information in reasoning. In this week, you will learn how to reason from information that is communicated directly by means of truth-tables or Venn Diagrams.</p><p><b>LEARNING OUTCOMES</b>: By the end of this week's material you will be able to: <ul><li>understand the information conveyed by a Venn Diagram</li><li>use Venn Diagram to determine whether a deductive argument is valid</li></p>...

Catch-Up and Final Quiz

<p>This week gives you time to catch up and review, because we realize that the previous weeks include a great deal of challenging material. It will also be provide enough time to take the final quiz as often as you want, with different questions each time. </p><p>We explain the answers in each exam so that you can learn more and do better when you try the exam again. You may take the quiz as many times as you want in order to learn more and do better, with different questions each time. You will be able to retake the quiz three times every eight hours. You might not need to take more than one version of the exam if you do well enough on your first try. That is up to you. However many versions you take, we hope that all of the exams will provide additional learning experiences. </p>...

Really good course, the material and explanations are good, and even in some cases, resolving or understanding some ideas is challenging, you can get the idea with a little practice

This entire series was informative, engaging, and fun, and the thinking skills taught are so valuable.
