Why critical thinking is key to using AI wisely

Returning guest writer Stephanie Simoes is the mind behind Critikid.com, a website that teaches critical thinking to children and teens through interactive courses, worksheets, and lesson plans. This article is meant to help educators (and parents) more effectively teach kids to use large language models and other forms of AI in positive ways.

 
In the Phaedrus, Plato expressed concerns that if men learned writing, it would “implant forgetfulness in their souls.” A 1975 issue of Science News referenced a survey that revealed that “72 percent of those polled opposed giving every seventh-grade student a calculator to use during his secondary education.”

Generative artificial intelligence is the newest target of that same opposition, and the debate has intensified since the U.S. Department of Education released its Proposed Priority on Advancing AI in Education.

“Advancing AI in education” can mean different things, but it generally falls into three main areas, all of which are addressed in the DoE’s proposals:

1. Teaching how to use AI—media literacy and how to effectively use LLMs as thinking helpers 

2. Teaching how AI works—expanding computer science lessons to teach the fundamentals of AI systems

3. Using AI to support instruction—empoying AI-driven tools to provide analytics and virtual teaching assistants 

Because I teach critical thinking—and because some critics worry that using AI is destroying our ability to think critically—I will explore the first area in this article.

One of the proposed priorities is teaching students to spot AI‑generated misinformation. That one isn’t especially contentious; spotting misinformation, including AI-generated misinformation, is a core part of modern media literacy.

The more controversial question is whether students should use large language models as “thinking partners.” The virality of the recent MIT study, “Your Brain on ChatGPT,” has amplified the fear that LLM use dampens our thinking skills. In the study, 54 adults wore electroencephalogram (EEG) caps while writing short essays. One group wrote unaided, another used a search engine, and a third relied on ChatGPT. Neural activity was highest in the unaided group, lower with search, and lowest with ChatGPT.

Those results, however, come with big caveats: the paper is still in preprint, the sample was small, and none of the participants were K–12 students.

Moreover, the reduced neural activity during ChatGPT‑assisted writing may simply indicate cognitive offloading, the practice of using external tools to reduce mental effort. From maps to calculators to writing lists of things we need to remember, humans have long been engaging in this practice. Cognitive loading isn’t necessarily a bad thing, as it allows us to spend our mental energy on higher‑order tasks. However, it must be implemented carefully in a classroom.

For instance, calculators support higher‑level math education only after students learn arithmetic. Similarly, children should develop basic writing and reasoning skills before using AI as a helper.

Moreover, we need solid subject-specific knowledge before using LLMs as research assistants; otherwise, we lack the expertise to evaluate the results. If we skip those steps, we risk producing a generation of incompetent experts.

But used correctly, AI can be a powerful tool for strengthening students’ critical thinking skills.

Critical thinking is slow, careful thinking. It allows us to question assumptions, spot biases, and weigh evidence. LLM outputs can be flawed or biased like any human source, so their responses deserve the same scrutiny. That scrutiny must sit alongside intellectual humility—recognizing when we don’t (yet) know enough to judge a claim. Students already practice these habits when they evaluate social media posts or websites; LLM outputs are simply the newest arena to apply the same skills.

A drawback of LLMs is that they amplify confirmation bias when we prompt poorly. Ask, “Give me evidence for my belief,” and they may oblige. This flaw can be turned into a lesson about both responsible prompting and confirmation bias. Teach students to prompt “Show the strongest evidence for and against this claim,” and then point out the human tendency to pay more attention to the pieces of evidence that support our preconceptions.

Better yet, have students ask the LLM to challenge their beliefs: “Show me evidence that I am wrong about this.” By prompting for dissent, students learn to explore their beliefs and may even change their minds about some unsupported ones.

History shows a pattern when it comes to new technology: panic, adaptation, and, finally, integration. The task of educators isn’t to shut the door on AI, but to teach students to use it wisely.

Project Week at Headwaters School: Turning curiosity into creation

Paul Lambert, Headwaters School mathematics guide

Like Paige Arnell’s recent guest post for the blog, this piece by Paul Lambert is about one school’s approach to creativity—in this case a step-by-step collaborative method to get special student projects underway. Paul is a mathematics guide at Headwaters School in Austin, Texas.

Every year since 2004, Headwaters School has held Project Week, a unique departure from regular classes during which students choose their topic of study, determine their learning objectives, and share their passions with our school community. Over the years, Project Week has inspired a variety of creative projects, including building a robotic wolf, writing and illustrating a children’s book, designing a biometric sensor, and producing a short documentary about Project Week itself.

Embarking on a big creative endeavor like this can feel overwhelming for our students, so for the last two years we have instituted a structured, step-by-step idea-generation process tailored for middle and early high school students. This framework allows every student to transform their curiosity into a fully realized creation.

Step 1: Brainstorming

We start by getting students' creativity flowing. Each student spends five uninterrupted minutes writing their interests, curiosities, or things they’d like to explore on sticky notes—one idea per note. To encourage a productive session, we emphasize three practices:

• Deferring judgment: Every idea is valid at this stage of the process.

• Encouraging wild ideas: Unconventional concepts often lead to breakthroughs.

• Prioritizing quantity: More ideas mean more possibilities.

By the end of this stage, students have a stack of sticky notes brimming with potential.

Step 2: Mind-Mapping

Next, students work in groups of three or four to organize their sticky notes into categories. Each group decides how to categorize ideas and how each idea fits inside the category. Then, they create a mind map with “Project Week” at the center and their categories branching out as spokes. This collaborative activity helps identify connections and themes, setting the stage for focused exploration.

Step 3: Concept Development

Once students have collected and categorized their interests, they dive into developing some full project concepts. Students are encouraged to think about how they could combine multiple interests (from the same category or across categories) into one project idea. This is a process that takes time and a great deal of careful consideration.

1. Each student divides an 11" x 17" sheet of paper into three sections and is given 15 minutes to develop three distinct project ideas with as much detail as possible.

2. The papers are then passed to the next member of the group. Each student has 3 minutes to add to or modify the concepts on this page, ensuring no one erases anything.

3. Papers are passed around the group until all members have added to each paper.

This method encourages diverse perspectives while preserving the originality of each idea.

Step 4: Gallery Walk

To gather broader feedback, we have a Gallery Walk. Students display their concept pages around the room or on their desks, and their peers provide constructive comments and suggestions as they stroll around the space. To foster a supportive environment, we ask students to offer two positive remarks for every critique.

By the end of this stage, each concept is enriched with fresh insights, helping students refine their ideas further.

Step 5: Finalizing the Project Idea

With these improved ideas, students choose one concept to develop into their final Project Week plan over the next week. They reflect on key questions to guide their decision:

• What do you hope to learn?

• What skills do you hope to develop?

• What do you hope to create?

• Why is this project important to you?

• Why is this project interesting to you?

Answering these questions helps students articulate the purpose and significance of their project, preparing them to pitch their ideas the following week.

Why This Process Works

This idea-generation process was adapted from the Engineer Your World course at the University of Texas and designed with our middle and high school students in mind. It breaks the intimidating task of starting a project into manageable, engaging steps while fostering creativity, collaboration, and critical thinking. By the time students present their project pitches, they’ve already invested thought, effort, and enthusiasm into their ideas while also receiving feedback, lowering the risk when presenting.

Through brainstorming, mind mapping, developing their concepts, and peer feedback, students learn how to turn a simple curiosity into a meaningful project—and, in the process, discover the joy of exploring their passions.

The imagination is an essential tool

We’re pleased to welcome Paige Arnell to the blog as a guest writer on the role of imagination and creativity in education today. Paige is the head of school at Kirby Hall School, which serves PreK through 8th grade learners in Central Austin.

The imagination is an essential tool of the mind, a fundamental way of thinking.
—Ursula K. LeGuin

The changing landscape of childhood is much discussed in the parenting and education world. The reality of digital saturation generates much debating of how, when, and where, and pundits of varying authority weigh in on benefits and dangers. Whatever your philosophy, there is no question that we’ve entered a radically new way of growing up. 

There are many points of entry for the anxious here. No matter your pedagogy or teaching philosophy, for all educators it is a time of considerable questioning and revising. 

One thing that is becoming more and more evident is that for earlier generations so much of the “work” of learning was happening outside of the schoolhouse door.  When children were bored and left to their own devices—without devices, when children were gathering in groups together to make their own entertainment, when children were staring down the long hours of a blank afternoon, they were actively engaging in this essential work of imagining. Out of necessity, they made something out of nothing. They invented a landscape of discovery and collaboration. Obviously, some children did more than others; there were leaders and followers. This is not new information. Waxing nostalgic for childhoods of the past appears to be a perpetual exercise of adulthood; however, what we are newly considering is how much this work of recreation dramatically affected the tasks of the classroom. We now are seeing that children entering school without this practice are at a deficit, and that the tasks of deep learning are becoming more difficult for them. 

Imagination is the foundation of critical thinking. Without imagination, we have no creativity, we have no curiosity. Without imagination, one might argue, we have no thinking. 

This is nothing new, and resources abound for creative activities for children. Unfortunately, what many of these amount to are really no more than decorative activities. A creative writing prompt, a craft with a specific end product, a writing “journal” with pre-filled images and fill-in-the-blank responses. Perhaps some glue, glitter, and markers will be involved. These are nice activities, and many children enjoy them, and they make for cute wall decoration, but they rarely require real working of the mind.

These times require more from all educators. These times require us to ask ourselves more challenging questions. They require us to evaluate what it might mean to prioritize the imagination within our classrooms and schools. 

If we truly take as a foundational principle the claim that “the imagination is an essential tool of the mind,” how might we need to reconsider the primacy of imaginative activity in learning environments, primarily in early childhood education? What does it mean to be free to imagine? Does it mean that we give ourselves permission to think of new things? Does it mean we give ourselves permission to try something really new—at least for us? Does it mean that we allow ourselves to act a different role, to move our bodies in a different way, to try a different voice, to try a new style of writing? Does it mean that we allow our mind to wander so freely that anything can happen … a puddle can become the ocean and twigs and leaves can become great ships? Does it mean that we allow ourselves to write familiar words in new combinations?

Yes, we might say, and we might say yes quite easily. In these times—in these times in which the mind is distracted almost continuously and so very rarely given the quiet and time it needs to drift into the world of imagination—in these times, educators must push themselves even further. We must push ourselves beyond a simple yes and into a deep consideration of the fundamental changes that a radical commitment to honoring the work of the imagination would look like beyond glittery decoration. 

If we believe that the transformative and powerful work rests on a bedrock of imagination and creative thinking—that critical thinking and the production of ideas can only grow from this rich soil—then how do we need to change our classrooms? It seems we must give our students a few things:

• We must give them time, specifically, unstructured time. If we fill their days with tasks and to-dos, they may never reach the space in which a stick becomes a wand or a telescope. 

• We must show them our own willingness to play and engage with the world in new ways. If we view children’s imaginative free time as time for us to check out of their world, we are showing them that imagination is secondary.

• We must give primacy of place to their creations and to their work—no matter how messy it may be. Imagination vitally requires process and not production. Let’s take down the professionally made posters. Let’s allow our students to create the classroom.

We’re called now to create communities in which school provides an almost sacred place for play and exploration, for the joy in creating and making messes. Parents and educators have an incredible opportunity to support each other in this work that may not produce a worksheet one can tape to the fridge, but rather supports the growth of a mind in all of its wonder and full humanness.

Discover some gems south of the river: The Small Schools of South Austin Educational Fair

Frequent blog contributor Marie Catrett, of Tigerlily Preschool, and her colleagues at the Small Schools of South Austin, have an invitation for you and your family:

I'm spreading the word about the upcoming Small Schools of South Austin Educational Fair happening on Saturday, April 5th, 9am–noon, at upRising Church, located at 8601 S. 1st Street, Austin Texas 78748. This is a free family event, open to all. 

Small Schools of South Austin is a group of educators, each of us independently running a small school program somewhere south of the river. Our collective is a varied group. We have differing educational inspirations and philosophies—some of us focus on outdoor learning, some are play based. Many of our members are Montessori guides, while others find inspiration in Waldorf or the Reggio approach. We have programs that view learning through the lens of exploring art or prioritize giving children space and freedom outside the city limits. Still others of us are looking to reinterpret existing labels, attempting to describe something that hasn’t existed before. Many of us are teaching and raising our own children. A common cause for creating a small school is that the program you wanted for your child didn’t exist yet. And if you’re pretty brave, determined, and maybe a little crazy, you make it happen. 

Small schools are wonderful schools. You can find reduced class sizes and beautiful, home-like environments with so much love and character. In these spaces, children are seen. In these groups, children become known. There’s a sense of freedom and choice on the part of those teaching. We are here to bring our vision, without administrative hindrances, directly into the lives of the children who need us. 

It can be hard to discover that we exist as an option for your family. We’re tucked away. We’re part of a connected but smaller immediate community. You need to hear about us from a neighbor maybe, or a friend. We’re, well, small. 

The Small Schools of South Austin collective formed to help more families connect with our programs. In the fall we host a multiple-schools-wide open house day, where each school opens their doors for the morning and families are able to tour several of the programs they’re most curious about. This spring marks our inaugural educational fair, where around twenty participating programs will be set up under one roof. Families are invited to come browse our tables to learn more about each of our programs and upcoming enrollment options. Schools will offer hands-on activities for children at many of the booths, host several local vendors, and feature a music performance. 

Please encourage your friends and neighbors to attend. We are community gems who want—and deserve—to be discovered. 

We hope to see you there!

Beyond the ABCs: Understanding progressive education

 Photo by Daiga Ellaby on Unsplash

Guest contributor Geoff Harrison is the founder and head of school at The Compass School. With over three decades of experience in education, he is bringing a new school to Austin: a school where students embark on a journey of curiosity, discovery, and learning rooted in research and progressive education principles.

As a parent, you want the best for your child's education. You've likely heard the term "progressive education," but what does it actually mean? It's more than just a buzzword; it's a philosophy that puts your child at the center of learning, emphasizing critical thinking, creativity, and collaboration over rote memorization. It promotes a joy for learning and helps to cultivate lifelong learners. This article will break down the core principles of progressive education to help you understand if it's the right fit for your family.

The Beginning of Progressive Education

Progressive education didn't spring from one single source but rather evolved from a confluence of ideas and movements, primarily in Europe and the United States, spanning the 17th to the 20th centuries. The term “American Progressive Education” was coined in the 20th century by John Dewey, Maria Montessori, Caroline Pratt, and Lucy Sprague, and it has been supported by recent neuroscience research, which acknowledges that a child who has autonomy—a voice in their own education—learns best.

It's important to note that progressive education has taken various forms and interpretations over time. While some approaches emphasize individual freedom and creativity, others focus on social reform and preparing students for democratic citizenship. However, the core principles of child-centered learning, active engagement, and critical thinking remain central to the philosophy.

Traditional education often focuses on memorizing facts and figures, preparing students for standardized tests. Progressive education takes a different approach. It believes that true learning comes from active engagement, exploration, and discovery. Instead of passively receiving information, children in progressive classrooms are encouraged to ask questions, investigate, and construct their own understanding. Students pursue their curiosity, develop compassion, cultivate courage, and enjoy a level of autonomy.

It’s All About the Learner, the Whole Child

Child-centered learning is at the heart of progressive education. The curriculum is designed to meet the individual needs and interests of each child. Teachers act as facilitators, guiding students’ learning journeys and providing support where needed. Learning is personalized and relevant to the child’s world. Progressive education also emphasizes hands-on, experiential learning. Students learn by doing, through projects, experiments, and real-world applications. This active approach fosters deeper understanding and makes learning more engaging.

Developing critical thinking skills is a priority in progressive schools. Students are encouraged to analyze information, evaluate different perspectives, and solve problems creatively. They learn to think for themselves, rather than simply accepting what they are told. Collaboration is another key component. Students work together on projects, learning to communicate effectively, share ideas, and respect diverse viewpoints. This fosters social skills and prepares them for collaborative work environments in the future.

Progressive education recognizes that children are more than just their academic abilities. It emphasizes the development of the whole child, including their emotional, social, and physical well-being. Schools often incorporate arts, music, and physical activity into the curriculum. Progressive classrooms often operate on democratic principles, where students have a voice in their learning and classroom management. This fosters a sense of ownership and responsibility. While assessments are still important, progressive schools tend to use a variety of methods to evaluate student learning, including portfolios, projects, exhibitions, and self-assessments. The focus is on understanding a child's growth and progress, rather than just assigning a grade.

The principles of progressive education have no limitations to where a child can grow and develop. It meets the needs of every child on their journey and promotes opportunities for advancement based on the individual child and not just standards.

Answering the “Should I?” and “Can I?” questions

Ken Hawthorn founded and runs “a school in a makerspace”: Austin School for the Driven. For this guest post I invited Ken to share his decision-making process when students propose projects that could be dangerous or controversial. In his candid response below, he invites readers to help him think through two specific (and real) dilemmas, either by emailing him directly or by leaving a comment here on the blog. —Teri

Our school bifurcates the teaching of skills and ethics. The answer to almost any “Can I?” question at our school is “Yes, and here is how.” The answer to “Should I?” needs to be explored in parallel with the “Can I?” question. As a school founder, I take great pride in how far we are willing to take that bifurcation at Austin School for the Driven.

Recently I have been navigating a few topics where I find myself hesitating to live up to giving students all the knowledge so they have the power to take a responsible approach to decision making in our school. With so many unique schools keeping Austin weird, I hope sharing my own challenges and discomforts around some student questions may be helpful or thought-provoking to others. 

Student Question #1: Can we spray-paint under the bridge and make a mural? 

I have been navigating this question for a year now. Spray-painting in the hands of children is nothing new at Austin School for the Driven. We have used spray paint on our RC car bodies and water-dipping projects. It makes me smile every time our school takes a field trip to Home Depot and we get the stink eye from security as our kids fill a small cart with spray paint cans. What is new is the student request to spray-paint in a public place.

RC car bodies spray-painted by students at Austin School for the Driven

There is existing spray paint on the walls of the tunnel they are targeting. If I said yes to this question, I would be a teacher leading students on an urban beautification project. On the other hand, saying yes to this question could be seen as an adult leading minors to commit a crime. For me this is a difficult question.

The students are absolutely serious about the quality of the proposed mural. To date, the students have scanned the tunnel with Lidar and created a 3D digital model that we can deploy at full-size scale as augmented reality inside of our classroom. We have found a spray paint simulator and are learning about the variety of nozzles that can be used to get very narrow or wide paint patterns.

What is the right decision here? What side should the “Should I?” land on this question?

Student Question #2: How does vaping work?

This is a “Can I?” question. I am totally fine having students do research and then discussing the “Should I?” part. What is less comfortable for me is providing knowledge involved with the “Can I?” question. It is sad that this question came up on one of our hikes along Shoal Creek Trail because there were so many of the disposable vaping devices littered along the trail.

No, we are not bringing a vaping device to campus, but building a functional model to vaporize propylene glycol or glycerol could be really educational. A vaping device actually is a reasonably technical machine. You have the battery, the heating coil, the baffle mesh, and a computer to regulate voltage, measure resistance, and target a certain wattage. There is a charging circuit and another circuit that acts as a fail-safe if the temperature goes up or there is too much battery discharge. There are also thousands of other machines we could build in the lab. Would building a model in some way still glamorize vaping?

I ask this question, and the question about spray-painting the bridge, because I don’t yet have an answer; I do not know what the right answer is. Austin School for the Driven exists as an experiment to see what happens when we hold standards and at the same time maximize student agency within a framework of “Yes,” “No,” and “Maybe” answers to questions of “Can I” and “Should I,” which then define the learning boundaries of the school.
