How to Reason Deductively Think Again: How to Reason and Argue Reasoning is important. This series of four short courses will teach you how to do it well. You will learn simple but vital rules to follow in thinking about any topic at all and common and tempting mistakes to avoid in reasoning. We will discuss how to identify, analyze, and evaluate arguments by other people (including politicians, used car salesmen, and teachers) and how to construct arguments of your own in order to help you decide what to believe or what to do. These skills will be useful in dealing with whatever matters most to you. Courses at a Glance: All four courses in this series are offered through sessions which run every four weeks. We suggest sticking to the weekly schedule to the best of your ability. If for whatever reason you fall behind, feel free to re-enroll in the next session.We also suggest that you start each course close to the beginning of a month in order to increase the number of peers in the discussion forums who are working on the same material as you are. While each course can be taken independently, we suggest you take the four courses in order. Course 1 - Think Again I: How to Understand Arguments Course 2 - Think Again II: How to Reason Deductively Course 3 - Think Again III: How to Reason Inductively Course 4 - Think Again IV: How to Avoid Fallacies About This Course in the Series: Imagine that a friend denies that modus ponens is a valid form of argument. Can you prove that it is valid without using modus ponens itself and thereby assuming that it is valid? If so, how? If not, what does this show about the validity of modus ponens? How can phrases like "and", "or", "if", and "not" work as "truth-functional connectives"? In this course, you will learn how to evaluate deductive arguments for validity. In particular, you will learn new ways of representing the information that is contained in the premises of a deductive argument. Using these new representational devices (devices that we call "truth tables" and "Venn diagrams"), we will be able to apply rules to determine whether or not a particular deductive argument is valid. Suggested Readings: Students who want more detailed explanations or additional exercises or who want to explore these topics in more depth should consult Understanding Arguments: An Introduction to Informal Logic, Ninth Edition, Concise, Chapters 6 and 7 by Walter Sinnott-Armstrong and Robert Fogelin. Course Format: Each week will be divided into multiple video segments that can be viewed separately or in groups. There will be short ungraded quizzes after each segment (to check comprehension) and a longer graded quiz at the end of the course....

This course sharpened my analytical thinking. Exam was deceptively difficult but worth taking multiple times.

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

This course is good, and it is helpful when it comes to reasoning deductively, but I do have one problem with it. Whenever I'm done with a certain portion of it, it obviously says that I need to do it when I've already done it. That needs to be fixed!

Compared to Think Again I, this II is more abstract and difficult. it takes more time to grasp the knowledge. and there are still things that I am confused about, despite having passed the final quiz.

The quizzes were a bit difficult because some of the items weren't discussed well in the lectures. It would be better if there were more comprehensive explanations to the answers in the quizzes

While still a very useful course, the material was less interesting to me personally than the first module. However it was still very rewarding and I enjoyed the instructor's lectures!

Somewhat confusing at certain points. The explanations don't exactly track the exercises that follow it. However, it is overall a useful course.

Great explanations for most subjects. The tests are significantly more complicated than the excercises covered by the lectures.

The course is extremely useful, but I found that the instructor is redundant. I often put the video speed on 1.5x.

A good continuation of Think Again I. However, final quiz had lots of bugs in it.

Would've liked more on the truth table of the conditional.

Interesting material, but the videos are sometimes hard to follow, and part of the truth-table exercises do not prepare too well for the Final Quiz questions on the topic

Still not very clear about Venn Diagram.

I did not enjoy this course despite loving Math and logical puzzles. I went into the Think Again series with a different expectation of using logical tools to analyse real life arguments - not harping on the entire time on abstractions. The tests were not very helpful again because they were very theoretical all the time. The final test was a nightmare honestly with much higher rigor required on the pure logic-based questions on truth tables - all the time kept me wondering why am I doing this.

it may be good for someone who is interested in logical thinking - for not someone who is looking at understanding and improving arguments - not that great.

In My Opinion,Dr.Neta And The Very Confusing Disorganized Final Quiz Really Ruined This Class For Me.No Matter What Answers You Choose You Will Always Get 30%.I Cannot Finish This Course Until What Ever Is Wrong With The Final Quiz Is Fixed,At That Time I Will Give This Course Four Stars.Also I Hope The Next Class Has The Other Instructor As The First Class In This Course Did.
