MISSION:  To improve K-12 instruction of critical thinking skills.

The Case for
Critical Thinking
Everyone agrees critical thinking is paramount, but it doesn’t appear evident in political partisans, science deniers, and conspiracy theorists. They have access to all the same information, but they lack the skills to distin­guish fact from misinformation, all while claiming they are the true critical thinkers. Facts alone do not foster critical thinking.

Schools certainly highlight critical thinking as one of their highest goals. But the Common Core State Standards (CCSS) and Next Generation Science Standards (NGSS) are not very specific about how to teach it. Other sources are equally vague and abstract, so I have outlined specific component skills that are practical to teach:

Critical Thinking
Abstract Definition: Decision-making and problem-solving using reason, logic, analysis, unbiased objectivity, and good judgement.
Practical Definition: Detecting bad reasoning (from yourself too) especially to detect false claims even when some information is unknown.

Component Skills:
Fact / Opinion
Logical Fallacies
Correlation / Causation
Credibility, Bias, Motive: Media Literacy
Experimental Method

Note that logic is the application of objective rules, which is taught through math and other subjects. Analysis is breaking down ideas into smaller components, which is also taught. Knowledge helps inform your judgment. Critical thinking incorporates all to make a subjective judgment.

In the CCSS & NGSS this is how many standards mention each skill. Most critical thinking skills are cited much less than Quadratic Equations and Vocabulary:

Standards Qty Grade
Experimental Design 1 5
Correlation/Causation 1 HS
Fact/Opinion 3 6-8
Fallacious Reasoning 3 9-10
Credibility, Motive 11 6-12
Quadratic Equations 14 9-12
Vocabulary 17 4-12

Actual classroom data shows a similar imbalance where critical thinking skills are taught significantly less. Here is relatively how many assignments and tests are given for various skills:

“One of the first things taught in introductory
statistics textbooks is that correlation is not causation.
It is also one of the first things forgotten.”
— Thomas Sowell

These are skills that need to be practiced regularly, not just taught once. If critical thinking is at least as important as math and vocabulary, then it should taught just as much.

Since the CCSS & NGSS do not specifically require many component skills for critical thinking, this is probably why many teachers spend so little time on them. We need to revise the standards, or the state curriculum standards, or augment the district and school curriculum.

Of course class time is limited, so adding more requirements means removing other parts of the curriculum, which is a difficult and painful decision. I believe it would be wise to identify parts of the curricula that are rarely used or remembered beyond school, to replace that instruction time with more critical thinking skills. To paraphrase a proverb:

Teach someone a lesson, they learn for a day.
Teach someone to think, they learn for a lifetime.

To fill gaps in the curriculum, I am developing free learning apps, and more curriculum developers need to create more content for these skills.

Educational institutions, from elementary schools to universities, could make critical thinking a greater part of their curricula. Rationality should be the fourth R, together with reading, writing, and arithmetic. Mere instruction fails to provide lifetime immunity to fallacies, and almost no one makes the leap from abstract principles to everyday pitfalls. But well-designed courses and video games — ones that single out cognitive biases, challenge students to spot them in lifelike settings, and provide immediate feedback — really can train them to avoid the fallacies outside the classroom.
