What is critical thinking?

Guest contributor Stephanie Simoes is the founder of Critikid.com, a website dedicated to teaching critical thinking to kids and teens through interactive courses, worksheets, and lesson plans.

“Critical thinking” is a trendy term these days, especially in the education world. Alternative schools in Austin commonly advertise that they encourage kids to think critically. Conversations about critical thinking are often accompanied by some version of the Margaret Mead quote, “Children must be taught how to think, not what to think.” But such discussions often neglect a crucial question: “What does it mean to teach children how to think?” Critical thinking is an abstract term. Are we all on the same page when talking about it?

As the founder of a critical thinking site for kids, this question is important to my work. We all get what “thinking” is, so the real question is—what makes it “critical”? I like to use a simple definition: critical thinking is careful thinking. It requires slowing down and questioning our assumptions.

Fast and Slow Thinking

Our brains are hardwired to respond to stimuli quickly, a crucial advantage in emergencies. When faced with a potential threat, immediate reaction is essential—there’s no time for deliberation. While this quick thinking might make us mistakenly perceive a harmless situation as dangerous, it’s a safer bet to err on the side of caution in high-stakes moments. It’s a matter of survival: better to assume danger where there is none than to overlook a real threat.

While fast thinking[1] is a valuable skill, it is prone to errors.

Here’s an example. Try to answer this question in less than 5 seconds:

If 1 widget machine can produce a total of 1 widget in 1 minute, how many minutes would it take 100 widget machines to produce 100 widgets?

After you’ve given your quick, intuitive answer, take as much time as you need to think about it.

Many people’s initial, intuitive response is 100 minutes. However, with more careful thought, we see that the correct answer is 1 minute. (The production rate per machine is 1 widget per minute. The rate doesn’t change with the number of machines.)

The key takeaway of this puzzle is that careful, deliberate thinking is often more accurate than quick thinking.

Applying slow, careful thinking to every daily decision would be impractical. Imagine how long you would spend at the grocery store if you conducted a deep analysis of every single choice! In many cases, our intuitive, fast thinking serves us well. However, problems can arise when we cling to the conclusions drawn by our fast thinking—especially in situations where accuracy matters.

In the widget machine problem, it’s relatively straightforward to recognize and correct our intuitive response with a bit of careful thought. However, letting go of our intuitive conclusions is not always this easy.

Humility and Critical Thinking

We might cling to our intuitive answers, even when faced with clear evidence or reasoning that challenges them, for several reasons.

First, it can be hard to change our minds when the intuitive answer feels very obvious or the correct answer is very counterintuitive. A famous example is the Monty Hall Problem. The correct answer to this puzzle is so counterintuitive that when Marilyn Vos Savant published the solution in Parade Magazine in 1990, the magazine received around 10,000 letters (many from highly educated people) saying she was incorrect!

It can also be challenging to let go of wrong answers when we have invested in them, such as by spending time and energy defending them. Sometimes, it’s simply a matter of not wanting to admit we were wrong.

Critical thinking requires more than just slow, deliberate thought. It also demands an open mind, humility, and an awareness of our minds’ flaws and limitations.

Building Blocks of Critical Thinking

Paired with slow, deliberate thought and humility, the following tools help us to be better critical thinkers so we can communicate more clearly—even when communicating with ourselves:

1. An understanding of cognitive biases: These are systematic errors in our thinking that can lead us astray. There are many online resources that explore these biases in detail.

2. An understanding of logical fallacies: These are flawed arguments. Logical fallacies can be used deliberately to “win” a debate, but they’re often made accidentally. Recognizing logical fallacies helps us to keep conversations on track. You can learn about some common logical fallacies in my Logical Fallacy Handbook or teach your kids about them with my online course, Fallacy Detectors.

3. Science literacy: We were taught many facts in science class, but many of us never really learned what science is and how it works. This is the foundation of science literacy. For an introduction to this, I recommend biology professor Melanie Trecek-King’s outstanding article “Science: what it is, how it works, and why it matters.” Another important part of science literacy is knowing How to Spot Pseudoscience.

4. Data literacy: Data literacy is the ability to properly interpret data to draw meaningful conclusions from it (and to know when drawing certain conclusions is premature). It means understanding how data is collected, identifying potential biases in data sets, and understanding statistics. Data literacy helps us make sense of the vast amount of information we encounter daily. You can introduce your teens to some common errors in data collection and analysis in Critikid’s course A Statistical Odyssey—a course that adults have enjoyed and learned from, too!

Preparing Kids for the Misinformation Age

A quick scroll through social media reveals a minefield of bad arguments and misinformation. You have probably come across logical fallacies like these:

“You either support A or B.” (False dilemma)
“Buy our product—it’s all natural!” (Appeal to nature)

The lack of science literacy among influential voices is also concerning. I can’t count how many times I have seen or heard the phrase,

“Evolution is just a theory.”

This phrase confounds the scientific and colloquial definitions of theory. If unintentional, it demonstrates a lack of science literacy; if intentional, this is a logical fallacy known as “equivocation,” in which a word is used in an ambiguous way to confuse or mislead the listener.

The need for data literacy is also apparent. You may have heard arguments like:

“Illness X has increased since Y was introduced, so Y must be the cause.” (Mistaking correlation for causation)
“There are fewer cases of food poisoning among people who drink raw milk than those who drink pasteurized milk.” (Base rate neglect)

We have an incredible amount of data at our fingertips, but without data literacy, we don’t have the proper tools to make sense of it all.

Critical thinking shouldn’t be taught as an afterthought; it needs dedicated, explicit instruction. Children face a battlefield of misinformation and faulty logic every time they go online. Critical thinking is their armor. Let’s help them forge it.

The adult in the room

Dr. Erin Flynn, today’s guest contributor, founded and directs The Hedge School Cooperative, a small, inclusive high school in Dripping Springs. This piece is adapted from the school’s blog and addresses a simple topic that is often overlooked in discussions about education: the importance of kindness.

I was recently talking with a friend [read: ranting]. Earlier in the week, I had been called "too kind/nice/sensitive" for the billionth time. My friend asked me why it bothered me so much, and this is what I parceled out: I grew up with the label, and it followed me into teaching and later as a principal. It is never said as a compliment; it is often said as an admonishment. It is seen as weak and ineffectual, as though a kind/sensitive person cannot possibly do a good job.

What is even more troubling about this, to me, is the idea that a person being kind to students, especially middle school / high school aged students, prevents them from being effective teachers or leaders. Why wouldn't someone want to be kind and sensitive when working in a position of responsibility for students?!

Let me be clear, I am not talking about being a "pal" to students. I set and keep boundaries. And I do this while prioritizing how the minor in this situation is feeling. I am the adult in the room. What does this mean? I believe it looks like the following:

• I set the tone for the classroom, whether consciously or not, so I need to be conscious of what I am feeling and spreading.

• I acknowledge when I have been wrong and/or hurtful.

• I apologize.

• I try not to take things personally.

• When I fail at this, I do the following: take a break if needed; take the student aside to have a private conversation; acknowledge the harm caused by the comment/action (not the person); ask if they are doing okay and if I can help in any way; and always listen, listen, listen.

• I do not hold grudges.

These are not revolutionary tactics; I learned them from other adults in my life. These adults were compassionate, kind, and kept boundaries with me. Being the adult in the room is possible both to practice and to do consistently. (Even when you're not in a room.)

Finding balance in a self-paced process

Samantha Jansky and Janita Lavani are co-founders of Ascent: An Acton Academy in North-Central Austin. With many years of experience as Socratic guides and Acton curriculum developers, they have a lot to say about the balancing act required of both learners and adults in a flourishing self-paced learning environment. We’re pleased they agreed to share some of their wisdom with us on the Alt Ed Austin blog.

The ingredients of a healthy self-paced learning process can prove empowering and set learners up for success for life. However, there’s an element of balance required to pull them all together. Paradoxically, autonomy requires accountability, and flexibility requires structure. While it might seem as though these are in conflict, they work in tandem to give much-needed balance to an individual’s learning process.

Autonomy, as you could have guessed, is at the core of self-paced learning. At Ascent, the learners determine for themselves how and when to approach their work. They do so when they are motivated through pursuing their curiosities, when they are equipped to engage freely in their environment, and when they practice toward mastery. Learners are not bound by limits placed on them because of their age. They can go as far and beyond what is expected of them in a particular subject. They can also choose when to work on the material; perhaps they are someone who likes to focus on a certain subject for weeks at a time, or perhaps they like a little balance each day. Ultimately, it is up to them to decide how to approach their work.

The flexibility of self-paced learning plays into genuine autonomy. Learners practice adjusting timelines, revisiting concepts, and incorporating feedback, allowing them to navigate their learning journey with resilience and a growth mindset. it offers the opportunity to practice adaptability in the face of unforeseen challenges and push through when faced with resistance.

This flexibility, however, doesn’t imply a lack of structure or discipline; rather, it encourages individuals to take ownership of their learning journey and create the structure themselves through tools introduced to them (some examples include SMART Goals, the Urgent/Important Matrix, squad frameworks, and the badge system to stay on track). Self-paced learning means you work on each subject at your pace—slowing down when you need to grasp something, and accelerating once you’ve mastered a topic. Self-paced learning empowers individuals to keep moving forward.

One of the most important tools offered to learners in a self-paced environment is goal-setting: establishing realistic objectives and timelines to maintain a sense of purpose and direction. Goal-setting ensures that the learners stay focused, motivated, and accountable. In a learner-driven environment, the learners are accountable to their growth. A key difference between this and more traditional learning environments is that a learner’s standing in any subject area is not compared to a predefined standard; rather, their progress is measured against their past achievements and efforts. The practice of setting SMART (Specific, Measurable, Achievable, Relevant, Tough/Time-Bound) Goals is critical in this regard. A true SMART goal is challenging. It pushes your limits to see what you can do, and it is built upon past progress and learning. This is where the rigor of a learner-driven environment comes into play.

The combination of clear goals, accountability, and active engagement creates a tremendous amount of structure in a learner-driven environment—but it’s not a “top down” structure created by someone else. When the learners have autonomy over their learning and their work output, they are the ones creating the structure they need to thrive, leading to a strong sense of responsibility.

Here’s a story that pulls all of this together. It’s one of many examples we have seen over the years of the magic of balancing autonomy with accountability and structure with flexibility.

It was a chilly February morning, and one learner was celebrating. Running around the studio, she was ecstatic. “I got my level 2 Math badge, I got my math badge!” The other learners in the studio were not silent on the matter, either. Loud jubilation and high-fives took place all over the space.

This young hero had finally found her stride in math—a process that included a lot of help but that was hers to own. For a couple of years, she had struggled to find flow in this particular subject. Her squad frequently supported her in goal setting, and her guides engaged her with questions and challenged her to set tough goals and develop a regular practice. She had the tools, such as SMART goals, a watch that reminded her to take quick breaks before getting back to work, a badge system that offered extrinsic motivators in each subject area, and powerful online platforms. She had the support of her parents, who checked in with her frequently but were also aware of when they needed to give her space; they also left her plenty of space to fail (and to own that, too).

This recipe was one for success, but she needed time to find her stride—to accomplish big wins in math on her timeline, at her pace. This allowed her gradually to build up confidence. She faced setbacks and learned to lean on her support system when she got an answer wrong—asking for help when she needed it—and eventually built up the mental muscle she needed to resist the urge to give up when she got an answer wrong. After months of setting daily math goals to create a habit, having the discipline to tell friends she was working, using her watch, and rewarding herself with reading after she finished her math goal, she created a structure that worked for her and found flexibility in her practice.

She had full autonomy (no one was going to make her do her work) but was also accountable to her goals and to the people she pulled in for support. She felt pressure, but it was rooted in her self-paced striving toward mastery. Most importantly, she owned the whole process, all the ups and downs, and so in the end, she realized her potential all on her own.

Tips for decreasing sensory overload in your highly sensitive child

We’re pleased to welcome Laura Sanders, MA, LPCA, as a guest contributor to the blog with two pieces this week aimed at helping parents and educators better understand and support highly sensitive children. Laura is a licensed counselor, EMDR trauma therapist, author, and mindfulness teacher specializing in working with highly sensitive children and adults at Cosmic Heart Counseling in South Austin and online.

When a child becomes overwhelmed, their nervous system is in overload. To prevent a meltdown or diffuse one that has already started, you have to work to get the nervous system regulated again. Remember, their capacity to hold sensory information and emotions has a lower threshold than that of neurotypical children. Here are some tips to help things run more smoothly in your household!

Increase communication.

Give your child language so they can tell you when they are getting overwhelmed. Have them pick an animal that they think best embodies their meltdown. For example, they may call big scary feelings “an angry monkey.” When they start to feel it coming on, they can say, “Angry monkey is here,” or you can ask, “Is angry monkey coming?” and you can try to intervene before it gets out of control.

Many times, there is a physical cue causing your little one to react.  It could be as simple as being hungry or tired. While most children get cranky when they are hungry, thirsty, or tired, an HSP child is even more sensitive to these physical cues, meaning their reaction to the sensations of hunger or tiredness will increase. When we need to eat, a stress hormone called cortisol is on the rise. HSPs are also more sensitive to any hormonal fluctuations, which may also contribute to extra discomfort.  

Ask them where they are on their sensory meter (you can come up with a fun name for it together) but on a scale of 1–10, they can tell you how overwhelmed they are. If they are at a 7 or higher, it’s time to take a break.

Strive for a more natural lifestyle.

Decrease the use of chemicals and fragrances in the house. Free and clear laundry detergent and dishwashing soap can help their sensitive noses and skin. Watch processed foods. Chemicals, dyes, and sugars in food will lead to more dysregulation, hyperactivity, and meltdowns. Certain medications can interact with brain chemistry and can cause a sensitive person to become dysregulated, and many HSPs do not react well with pharmaceuticals made for neurotypical brains and bodies.

Create a chillout spot.

Find a spot in your home that you can make a comfort zone. Have your child help build it with blankets, soft lighting, snuggle friends, and anything they will find comforting. This can be a place for them to retreat to when they begin to feel overwhelmed. It can also be a place for them to go to as an alternative for punishment. Many times, a less than ideal behavior reflects a need for a calmer environment, rather than a need for punishment.

Take breaks.

A full day of running errands and playdates may be fun, but it could lead to overwhelm by the time you are ready to come home and relax. Checking in with your child frequently about where they are on their sensory meter or whether they are hungry can go a long way.

Let the child pick fabrics and clothing.

Allowing the child to tell you which clothing and fabrics they find overstimulating can be a game changer. Your day is doomed if your child starts out overloaded with tactile discomfort. Involve them in the process, and once you find what works, stick with it. As they get older, their clothing and fabric needs will change, so check in often.

Get tested for food allergies or cut out common allergens.

Food allergies are everywhere these days. Most HSPs are allergic to many different foods, and this can cause not only physical discomfort but also inflammation, brain fog, and even behavior changes. Getting tested can be pricey and time consuming. Many people choose to follow an elimination diet and see what works from there. You could also just cut out common allergens (dairy, gluten soy, sugar) and see what miracles happen!

Consider supplements.

There are lots of supplements out there that be helpful to calm down an overwhelmed nervous system, or ease anxiety. Some are branded for children, and some are branded for adults. Talk to a doctor or herbalist about which supplements can help with daily brain function and acute stress.

Practice breathing exercises.

My favorite exercise to do with kids is “Sniff the Flower, Blow out the Candle.” This has them take a big inhale through their noses and slowly exhale through their mouths.

Try physical helpers.

Sensitivity to the environment doesn’t mean that zero stimulation is ideal. A physical helper like a weighted blanket or a giant stuffed animal can provide much-needed comfort to an overstimulated child and help them get back to their baseline.

I hope you found this list helpful! If you are not sure if your child is highly sensitive, check out my related blog post here on Alt Ed Austin, “Is your child highly sensitive?” For more information on this topic, visit therapyforsensitives.com.

Is your child highly sensitive?

Laura Sanders, MA, LPCA, is a licensed counselor, EMDR trauma therapist, author, and mindfulness teacher specializing in working with highly sensitive children and adults at her private practice, Cosmic Heart Counseling, in South Austin and online. We’re happy to welcome her as a guest contributor to the blog with two companion pieces this week to help parents and educators better understand and support highly sensitive children.

High sensitivity is a form of neurodivergence that is gaining in recognition and popularity. An highly sensitive person (HSP) is just that—highly sensitive. Their ability to tolerate sensory information and emotions is smaller than that of others, leading to overwhelm. A highly sensitive person has a finely tuned nervous system that can prime them for anxiety and stress. Without positive coping skills, this sensitivity can be overwhelming and lead to a host of behavioral issues in childhood and beyond.

With knowledge, understanding, and positive coping skills, sensitivity can be a superpower! Although navigating the challenges of sensitivity can be difficult, your child’s sensitivity can wield multiple gifts, including creativity, empathy, and even intuition.

Many adults are becoming aware of and owning their sensitivity, gaining coping skills, and thriving. For children, it can be more difficult as their brains, bodies, and nervous systems are constantly growing and changing. They have little control over their daily activities, foods they eat, and clothing they wear. An HSP child is even more vulnerable to the environment as exposure to even small amounts of stimulus may be too much.

To a neurotypical (NT) adult, the sensitive child might seem over reactive, overemotional, and dramatic. To the NT parent, the child is having an absolute meltdown because they don’t want to wear the shirt that was picked out for them. To the child, the physical body has become so incredibly uncomfortable that it causes stress hormones to spike. In turn, the child’s nervous system is activated, and they are flooded with emotions that they don’t know how to process. Screaming ensues.

To sensitive children, the world can seem entirely overwhelming. They may recognize that they respond differently to the world than their peers and not understand why. Arming them with knowledge, tools for self-care, and nervous system regulation at an early age can change the trajectory of their lives so they can use sensitivity as a superpower and avoid having to go through so much heartache.

So, how do you know if your child is highly sensitive? Here are some signs that might indicate your child has a finely tuned nervous system and might need some additional tools to thrive in our crazy world.

Sensitivity is threefold—physical, emotional, and energetic. Physical sensitivity affects the five senses: touch, taste, sound, smell, and sight. When any of these senses start to get overwhelmed, a highly sensitive person’s nervous system detects a threat and goes into hyperdrive.

 Here are some physical sensitivity signs that your child might be an HSP:

• allergies to perfumes and other synthetic fragrances in detergents, scented candles, and even dishwashing soap

• an aversion to certain types of fabrics or shapes of clothing

• complaints that certain environments, video games, or television shows are too loud

• multiple food allergies

• proprioception or tactile sensitivity

• meltdowns after time spent in big crowds or places with bright or fluorescent lights

 Emotional sensitivity can look like:

• crying easily

• having feelings hurt easily

• bursts of anger

• feeling overcome when watching television and movies

• feeling a high level of empathy for animals, stuffed animals, or other people

• a sense of not belonging

• asking deep questions or having deep thoughts

• being described by others as “an old soul”

Energetic sensitivity shows up in some children and adults as:

• a strong sense of overwhelm in crowded places

• connection to spirituality

• having an increased sense of imagination

• possessing “second sight” or psychic abilities

• heightened creative abilities

If you think you or your child might be a highly sensitive person, don’t worry! It’s not a mental illness, and it doesn’t mean anything is wrong. It just means that your child might need a little extra care in navigating the world. Little changes in the household can decrease sensory overload. Using fewer chemical cleaners and fragrances in the home, dimming the lights, and making time for “chilling out” in between activities can give your child’s nervous system a much-needed break.

Paper, please

Guest contributor Ken Hawthorn is back with a great art + geometry activity you can try with your family. Ken is the founder of Austin School for the Driven, a unique environment of experiential learning, the hacker mindset, and outdoor education, all curated by community. He is the author of Super Arduino and consults with both Austin Community College and the University of Texas at Austin on makerspace education and design.

Paper is a structural material that forms the basis for so many wonderful math, science, and art projects at school and at home. From slide rules to “sharks with frickin laser beams,” paper is an amazing place to start!

Today I want to share some recent explorations of pop-up card geometry and even provide you, dear reader, with the actual files we used in class at Driven so you can make the same project at home with a Cricut, scissors, or an X-ACTO knife.

The below picture is a prototype pop-up card design students constructed in the third week of school at Driven. The genesis of the idea was a collaboration between Adam Soto, a literacy teacher at Griffin School, and me, Ken Hawthorn. Adam works with his students to individually go through the process of writing their own novel. Adam and I were looking for meaningful project-based intersections that combined the makerspace and the novel-writing project.

We realized that cards people give each other are really about the story of two people and the relationship between them. A spouse purchases a card that has symbols and words that proclaim appreciation and love for a partner, mom might get a handmade card from a child with a drawing of the whole family, or a co-worker might select a card that expresses how good the recipient is at being an inclusive member of the team. Whatever the occasion, the well-chosen card will usually express not just a particular sentiment, but also images and words that reflect a relationship and shared experiences between two people. When a third party reads a card, originally given from one person to another, they can infer a lot about the story of that relationship based on the design of the card and the words used.

With this in mind, why not have students make cards that are not from one person to another, but that encapsulate the important parts of the novel they are reading or writing? In this case, students at Driven wanted to look at a fairytale castle. Below are the steps they took to create a pop-up castle card.
