16 Best Free Online Critical Thinking Courses

critical thinking classes online free

Written by Argumentful

Critical thinking is one of the most fundamental skills you could focus on. In fact, these skills are so important that many educational institutions have listed them among their central goals. Critical thinking helps you sort the true from the false.

The bad news is that not many people own these skills. Einstein famously said:

“Only two things are infinite, the universe and human stupidity, and I’m not sure about the former.”

The good news though is that you can improve your thinking and you can do it without breaking the bank.

Below are listed 16 of the best free online critical thinking courses with details regarding their contents.

Go on, choose your preferred course and take action today! (You can thank me later😉!)

P.S. Apart from the general critical thinking courses, I’ve included 5 specific ones which focus on today’s burning issues- fake news and climate change , as well as correctly interpreting randomized clinical trials and screening trials. See numbers 12 to 16 below.

PHIL102: Introduction to Critical Thinking and Logic

Course introduction.

  • Time: 40 hours
  • College Credit Recommended ($25 Proctor Fee) -->
  • Free Certificate

The course touches upon a wide range of reasoning skills, from verbal argument analysis to formal logic, visual and statistical reasoning, scientific methodology, and creative thinking. Mastering these skills will help you become a more perceptive reader and listener, a more persuasive writer and presenter, and a more effective researcher and scientist.

The first unit introduces the terrain of critical thinking and covers the basics of meaning analysis, while the second unit provides a primer for analyzing arguments. All of the material in these first units will be built upon in subsequent units, which cover informal and formal logic, Venn diagrams, scientific reasoning, and strategic and creative thinking.

Course Syllabus

First, read the course syllabus. Then, enroll in the course by clicking "Enroll me". Click Unit 1 to read its introduction and learning outcomes. You will then see the learning materials and instructions on how to use them.

Unit 1: Introduction and Meaning Analysis

Critical thinking is a broad classification for a diverse array of reasoning techniques. In general, critical thinking works by breaking arguments and claims down to their basic underlying structure so we can see them clearly and determine whether they are rational. The idea is to help us do a better job of understanding and evaluating what we read, what we hear, and what we write and say.

In this unit, we will define the broad contours of critical thinking and learn why it is a valuable and useful object of study. We will also introduce the fundamentals of meaning analysis: the difference between literal meaning and implication, the principles of definition, how to identify when a disagreement is merely verbal, the distinction between necessary and sufficient conditions, and problems with the imprecision of ordinary language.

Completing this unit should take you approximately 5 hours.

Unit 2: Argument Analysis

Arguments are the fundamental components of all rational discourse: nearly everything we read and write, like scientific reports, newspaper columns, and personal letters, as well as most of our verbal conversations, contain arguments. Picking the arguments out from the rest of our often convoluted discourse can be difficult. Once we have identified an argument, we still need to determine whether or not it is sound. Luckily, arguments obey a set of formal rules that we can use to determine whether they are good or bad.

In this unit, you will learn how to identify arguments, what makes an argument sound as opposed to unsound or merely valid, the difference between deductive and inductive reasoning, and how to map arguments to reveal their structure.

Completing this unit should take you approximately 7 hours.

Unit 3: Basic Sentential Logic

This unit introduces a topic that many students find intimidating: formal logic. Although it sounds difficult and complicated, formal (or symbolic) logic is actually a fairly straightforward way of revealing the structure of reasoning. By translating arguments into symbols, you can more readily see what is right and wrong with them and learn how to formulate better arguments. Advanced courses in formal logic focus on using rules of inference to construct elaborate proofs. Using these techniques, you can solve many complicated problems simply by manipulating symbols on the page. In this course, however, you will only be looking at the most basic properties of a system of logic. In this unit, you will learn how to turn phrases in ordinary language into well-formed formulas, draw truth tables for formulas, and evaluate arguments using those truth tables.

Completing this unit should take you approximately 13 hours.

Unit 4: Venn Diagrams

In addition to using predicate logic, the limitations of sentential logic can also be overcome by using Venn diagrams to illustrate statements and arguments. Statements that include general words like "some" or "few" as well as absolute words like "every" and "all" – so-called categorical statements – lend themselves to being represented on paper as circles that may or may not overlap.

Venn diagrams are especially helpful when dealing with logical arguments called syllogisms. Syllogisms are a special type of three-step argument with two premises and a conclusion, which involve quantifying terms. In this unit, you will learn the basic principles of Venn diagrams, how to use them to represent statements, and how to use them to evaluate arguments.

Completing this unit should take you approximately 6 hours.

Unit 5: Fallacies

Now that you have studied the necessary structure of a good argument and can represent its structure visually, you might think it would be simple to pick out bad arguments. However, identifying bad arguments can be very tricky in practice. Very often, what at first appears to be ironclad reasoning turns out to contain one or more subtle errors.

Fortunately, there are many easily identifiable fallacies (mistakes of reasoning) that you can learn to recognize by their structure or content. In this unit, you will learn about the nature of fallacies, look at a couple of different ways of classifying them, and spend some time dealing with the most common fallacies in detail.

Completing this unit should take you approximately 3 hours.

Unit 6: Scientific Reasoning

Unlike the syllogistic arguments you explored in the last unit, which are a form of deductive argument, scientific reasoning is empirical. This means that it depends on observation and evidence, not logical principles. Although some principles of deductive reasoning do apply in science, such as the principle of contradiction, scientific arguments are often inductive. For this reason, science often deals with confirmation and disconfirmation.

Nonetheless, there are general guidelines about what constitutes good scientific reasoning, and scientists are trained to be critical of their inferences and those of others in the scientific community. In this unit, you will investigate some standard methods of scientific reasoning, some principles of confirmation and disconfirmation, and some techniques for identifying and reasoning about causation.

Completing this unit should take you approximately 4 hours.

Unit 7: Strategic Reasoning and Creativity

While most of this course has focused on the types of reasoning necessary to critique and evaluate existing knowledge or to extend our knowledge following correct procedures and rules, an enormous branch of our reasoning practice runs in the opposite direction. Strategic reasoning, problem-solving, and creative thinking all rely on an ineffable component of novelty supplied by the thinker.

Despite their seemingly mystical nature, problem-solving and creative thinking are best approached by following tried and tested procedures that prompt our cognitive faculties to produce new ideas and solutions by extending our existing knowledge. In this unit, you will investigate problem-solving techniques, representing complex problems visually, making decisions in risky and uncertain scenarios, and creative thinking in general.

Completing this unit should take you approximately 2 hours.

Course introduction

Every day, be it in your private or professional life, you are required to take a position on a variety of subjects: a hot topic, a societal question, a thorny problem at work, etc. However, you won't necessarily have an intimate knowledge of all of these subjects, and that’s okay! So you might ask yourself the following questions: how do I form an opinion ? How do I sift through all of the available information ? How do I make a good argument ? We have an answer: learn to apply critical thinking !

critical thinking classes online free

This course offers you methods and practical tools to develop critical thinking for your everyday use:

You'll learn that your  mind  sometimes plays tricks on you by using  shortcuts  that help you decide quickly, but this is  cognitive bias  and might be misleading.

You will learn how to  question the world  around you and to structure your  search for information.

You will learn how critical thinking can help you to have  constructive debates  and avoid  bad arguments.

Why Study Critical Thinking?

Critical thinking means adopting an objective approach to the decisions you make, wherein logic, reason and rationale take the place of bias, manipulation and emotion.  Effectively, critical thinking is a mindset that enables you to reach opinions and make informed decisions through balanced and objective analysis of the available facts.  To become a critical thinker is to benefit from the ability to better express your thoughts, your beliefs and your ideas.  It can also help you become a better communicator, making it easier for others to understand you and for you to understand them.  In a nutshell, critical thinking could be described as the classic ‘out-of-the-box’ approach to thinking - closely connected with creative thinking.  Critical thinking skills come naturally to some, but for others must be studied and practiced to perfect.

By the end of this course the learner will be able to:

  • Define critical and non-critical thinking
  • Identify your critical thinking style(s), including areas of strength and improvement  

All free online certificate courses at Oxford Home Study Centre are 100% free of charge from start to finish.  There is no enrolment fee, all study aids are provided via our online learning platform and all of our courses are self-paced for total flexibility.

Ct700 - how to infuse critical thinking into your instruction.

critical thinking classes online free

This course  introduces a substantive conception of critical thinking and how to infuse this concept throughout your instruction. It fosters understanding of how to teach critical thinking skills to students through any subject or discipline, and at any level of instruction. In this course, you will be introduced to the elements of reasoning, universal intellectual standards, and intellectual traits through readings, discussions, and practical application activities. You will redesign lessons and strategies using the concepts and principles of critical thinking. You will practice strategies for Socratic discussions. You will help students learn to consciously use critical thinking concepts and strategies in learning, and in their lives. You will redesign and teach lessons you develop for your own classes - and receive course credit for doing so! 

As you apply your mind in this course, you can expect to:

  • deepen your understanding of the foundations of critical thinking;

critical thinking classes online free

  • develop skills and abilities in placing fairminded critical thinking at the heart of teaching and learning, including explicitly emphasizing the development of Intellectual Virtues among your students;
  • design instruction that fosters explicit critical thinking throughout your course(s);
  • help your students learn the tools they need for developing as ethical critical thinkers;
  • come to understand the role that native pathologies of human thought play in impeding intellectual development;
  • explicitly use the Elements of Reasoning and Intellectual Standards to create critical thinking lessons in your subject area(s);
  • help students cultivate their ability to think within key concepts in your subject(s) and discipline(s); and
  • create lessons and assessment processes that dovetail with fostering critical thinking at every moment of teaching and learning.

CT800 - Critical Thinking: Tools for Taking Charge of Your Learning and Your Life

critical thinking classes online free

Since few people realize the powerful role that thinking plays in their lives, few gain significant command of it. Most people are frequently victims of their thinking; that is, they are hurt  rather than helped   by it. Most people are their own worst enemies. Their thinking is a continual source of problems, preventing them from recognizing opportunities, keeping them from exerting energy where it will do the most good, poisoning relationships, and leading them down blind alleys.

This course will introduce you to the tools the best thinkers use and will exemplify the activities and practices you can use to begin emulating them. Here are some of the qualities of the best thinkers:

  • The best thinkers think about their thinking.    They do not take thinking for granted. They do not trust to fate to make them good in thinking. They notice  their thinking. They reflect   on their thinking. They   act  upon their thinking. 
  • The best thinkers are highly purposeful.    They do not simply act. They know why they act. They know what they are about. They have clear goals and clear priorities. They continually check their activities for alignment with their goals. 

critical thinking classes online free

  • The best thinkers distinguish their thoughts from their feelings and desires.    They know that wanting something to be so does not make it so. They know that one can be unjustifiably angry, afraid, or insecure. They do not let unexamined emotions determine their decisions. They have “discovered” their minds, and they examine the way their minds operate as a result. They take deliberate charge of those operations.
  • The best thinkers routinely take thinking apart.    They “analyze” thinking. They do not trust the mind to analyze itself automatically. They realize that analyzing thinking is an art one must consciously learn. They realize that it takes knowledge of the parts of thinking, and practice in exercising control over them.
  • The best thinkers routinely evaluate thinking, determining its strengths and weaknesses.    They do not trust the mind to evaluate itself automatically. They realize that the automatic ways in which the mind evaluates itself are inherently flawed. They realize that evaluating thinking is an art one must consciously learn. They realize that it takes knowledge of the universal standards for thinking, and practice in exercising control over them. 

This course, as a whole, will introduce you to the tools of mind that will help you reason well through the problems and issues you face - whether in the classroom, in your personal life, or in your professional life. If you take these ideas seriously, and practice using them, you can take command of the thinking that ultimately will command the quality of your life. 

  • understand what critical thinking is, how it differs from other forms of human thought, and its foundational principles and concepts;
  • become explicitly aware of the barriers to critical thinking development (egocentricity and sociocentricity), as well as how to recognize and overcome their many manifestations in daily life;
  • analyze thinking by breaking it down into its fundamental components (the Elements of Thought), and learn how those components work together in reasoning;

critical thinking classes online free

  • develop Intellectual Virtues, or desirable traits of mind, through practice over time;
  • formulate clear, important, relevant questions;
  • differentiate between questions of fact, of preference, and of reasoned judgment, and understand the best approaches to take for each of those categories;
  • read critically and writing substantively;
  • recognize the problem of media bias and propaganda as barriers to critical thought in individuals and human societies;
  • develop a clear framework for ethical reasoning and understand how it differs from other modes of thought, such as religious, ideological, political, and legal thinking;
  • learn the importance of fairminded critical thinking in self-actualization and the cultivation of fairminded critical homes, workplaces, classrooms, and societies; and
  • understand the stages of critical thinking development, as well as determine your current such stage and what is required to ascend to higher stages.

  • "I would like to express my deepest appreciation to you [Dr. Linda Elder] and Richard Paul. You both created a system for life guidance through your very arduous work on critical thinking. Thank you for adding the intellectual virtues to critical thinking. Critical thinking without the intellectual virtues is still narrow-minded thinking. Thanks to [instructor] Paul Bankes [CT700], we could get familiar with fairminded critical thinking this semester in the class. Since I have also attended a couple of courses in psychology, I could better understand what majestic guidance you have created to help us have better lives by improving our way of thinking. I just wanted to say "THANK YOU" for each second you have devoted in this way. I will try to internalize fairminded critical thinking in my life and help to develop this idea as much as I possibly can. I hope one day I can claim that I am from the community of Fairminded Critical Thinking."
  • "I would like to extend my sincere gratitude for allowing me to complete the CT700 Course. It has been the most humbling and enlightening experience of my academic life. . . . I will now embark on my vision to make a difference in the South African Education System. Once, again, my gratitude goes out to you . . . "
  • "CT700 was an excellent course that changed my thinking and life. It was painful at times and I found it took time for me to meaningfully complete the assignments. As I worked through the first few weeks, I also wondered if I would be able to change my thinking process. By the end of the course, I grew personally and professionally in ways that I wasn’t sure were possible."
