Let's Banish Critical Thinking, Part 3: Reason & Evaluate

No matter how close to the center their shot lands, beginning marksmen achieve success simply by hitting the target. As they learn, practice, and gain experience, the target’s center becomes their focus. They develop accuracy, intentionally steadying their state and securing the center in their sights. Thinking is similar. Engaging the target’s outer rings first supports movement toward the target’s center. Movement toward the center also increases the interaction between the rings.

Reasoning and evaluation, the target’s inner rings, are two sides of the same coin. Before we examine this coin, let’s briefly review the target’s outer circles: memorization and learning. Some information possesses its greatest value when it’s memorized. At its best, memorizing enables efficiency in thinking and acting. However, memorizing, while valuable when engaged selectively, has its limits.

Learning often involves four core processes, or four “states” of thinking. (Thinking is more fluid than the term states suggests, but this simplification can help us understand its flow.) Through experience, the brain gains raw sensory data. During comprehension, the brain sorts, labels, and organizes the raw sensory data. Through elaboration, the brain examines the organized data for patterns, recalls relevant prior experiences, and blends the new data with your experiences to construct understanding. During application the brain practices using or expressing the new understanding. We should increase instruction in the skills of learning, not just guide student learning of core subject matter. In other words, we need to place more value and emphasis on teaching students how to self-teach (or self-learn). We need to teach them the thinking skills that enable self-directed learning.

Reasoning builds on learning because it requires knowledge of the subject about which one wants to think. That may seem obvious, but some instructional thinking programs suggest that by using their bag of tricks students will be able to think critically about anything. While certain understandings and skills do enable reasoning, there must be sufficient knowledge about the subject to avoid reasoning void of solid content or invalid due to misunderstanding. Reasoning uses the ideas gained through learning to construct arguments, identify supportable conclusions, and structure ideas so that their relationships, value, and implications are evident. It also empowers decision-making.

Let’s watch learning and reasoning in action.

The Tour de France mesmerizes Stan. He knew that people raced on bikes, but he never saw the excitement this annual contest generates. A trip to a local bike shop intensifies Stan’s interest. The bikes themselves, the accessory equipment, the experience of freedom riding even in the store’s parking lot draws Stan into a new world, and, thus, into learning. In conversation with the store’s knowledgeable salesperson, Stan asks questions about bike types, manufacturers, and basic equipment needs. He leaves with a copy of a book, in which he seeks new information on bike selection and maintenance. His vocabulary expands, as terms like derailleur and carbon-fiber frame contribute to his emerging understanding. Stan researches road vs. mountain vs. BMX bikes and considers what type of cycling most interests him. He charts information about various makes and models of bike and reviews expert opinions on each. He considers this data from various perspectives: What do riders say about a make/model? What are repair shops’ experience with each? What does each manufacturer reveal about the intended use for each of their models? Stan actively seeks needed information and organizes and examines it in ways that deepen his understanding of this new world.

Stan grows more excited as his learning deepens, and soon he is eager to purchase his own bike.

Enter reasoning.


Decision-making is similar to constructing a valid argument, and making a sound decision requires many of the same understandings and skills. For example, Stan’s research may have revealed that Brand A offers a longer warranty on all its bikes than all the other manufacturers he reviewed. Thus, he forms a statement that represents reality (i.e., not an opinion)—a “categorical statement”: “Brand A’s warranty is longer than the other manufacturers I am considering.” As he continues to review what his research reveals, he forms several such statements—some universal and some particular in nature. Stan also monitors his thinking as he compares features on differing models. For example, Stan knows from his various test rides that he has a strong preference for a specific type of shifting and braking controls. When comparing controls, he stays aware that, because of his bias, he will likely favor models with his preferred controls. This is not an error in his thinking, but it does present an additional consideration.

Stan also monitors his thinking for fallacies. For example, he watches for post hoc errors, such as eliminating a make just because it is the company that supports his favorite cyclist’s main competitor—e.g., “They must make bikes for jerks because so-and-so rides one.”) He also tries to minimize emotionally potent factors—e.g., “I really like the detailing on this model. Since it’s cool, I’ll get that bike.”

Throughout this process, Stan is constructing a conditional argument with as much truth and validity his understanding of cycling allows. He is reasoning. When the time comes to discuss getting a bike with his parents, who offered to contribu
te to the purchase as part of Stan’s birthday present, he’s ready with a well-crafted “argument” and a decision made via his best reasoning abilities.

Note how Stan’s learning enabled his reasoning. Had he selected a bike on his first visit to the bike shop immediately following the Tour de France, he would likely have made a different, less-reasoned decision, which may or may not have proved
to be a wise choice. Emotion would have been the main basis of his decision because he did not possess the understanding that his period of learning provided. Without knowledge of a subject, we tend to make affective, less-informed decisions. (Note, you can never completely eliminate emotion’s role in decision-making, but you can moderate its influence. See Jonah Lehrer’s How We Decide for an extended discussion of this.)

Problem-solving follows a similar route. The first step involves lea
rning about the problem and its context (or reviewing such information if the problem arises in a familiar area). Reasoning then both produces and evaluates potential solutions. If the first attempt does not solve the problem, analysis of the attempt in relation to the problem often leads to another potential solution. Though we often portray trial and error as an unstructured process, the truth is that better trials often result from learning and reasoning. (Think about it, do you really want a surgeon who approaches a problem through a pure, unthinking trial-and-error approach?) Selecting a potential solution is not that different from decision-making, which is a focused form of reasoning.

Now, you may be wondering, why my visual, the target, separates reasoning and evaluation when both seem to be involved in forming valid and truthful arguments. When I use the term evaluation, I mean the capacity to analyze, evaluate, and accept or reject someone else’s argument. This certainly requires the same understandings and skills of reasoning, but it requires understanding the argument and its constructs as formed by someone else. Is this more difficult than forming valid arguments and engaging in metacognition throughout the process? I wouldn’t claim that, except that there is an additional step, and this additional step is crucial. The thinker must understand, without initial bias, the argument another makes. (We have plenty of adults in our nation’s capital and on our cable “news” networks who regularly demonstrate their lack of this crucial, additional step.) This requires overcoming challenges such as the error of discrediting the messenger rather than evaluating the message—an error that can hijack thinking before a single idea of the argument has been considered. This is a significant challenge that is largely absent from forming one’s own valid arguments.

Additionally, by learning to form truthful and valid arguments, students gain experiential knowledge that can aid valid evaluation. An analogy may help clarify this relationship. Housing inspectors undergo various levels of education and meet certain requirements depending on where their practice is located. Thorough inspectors often have construction experience. Knowing from experience where builders are tempted to take short-cuts helps the inspector know what to examine carefully. From constructing experience, the inspector gains knowledge that strengthens his evaluation capacity. Similarly, forming truthful and valid arguments aids evaluation of arguments made by others.

Reasoning and evaluation depend on skills. The table below details some of these essential abilities. (D. Q. McInerny’s Being Logical provides a great and succinct introduction to many of these concepts.)

These abilities can be viewed as a series of developmental steps that can be emphasized in the classroom. For example, a group of educators in Philadelphia took the ability to form conditional arguments and discussed, “What is the range of this skill? What do its initial steps of development look like? What would its fullest expression look like?” After we grappled with these concepts, we considered when instruction for each step might begin and where it might mature to mastery. Here’s what evolved:Exploring thinking in this way helps a plan for instruction to emerge. Teachers gain guidance for actually teaching thinking and can better plan for its inclusion in learning. Ideally, I believe we’d approach everything through a thinking lens. For example, instead of teaching magnetism as a science unit, we’d teach a thinking skill, such as stating premises and conclusions, using magnetism as the subject matter. Simply altering how we view and approach instruction can make the difference between students seeing us as the expert from whom they must learn and seeing themselves as capable learners who possess the skills they need to learn independently.

My intention in this series has not been to provide an exhaustive look at thinking but to suggest an alternate perspective. By seeing thinking as central to learning rather than a nice addition to classroom interaction, we can begin to explore the implications for our teaching, from what we teach to how we teach it. I have not explored creativity in this series. I plan to do so in my next post, which I’ll present as separate from this series.


Thank you for reading and for your comments. These posts are intended to be discussion starters. I certainly learn much from the interaction they spark. I hope you’ll learn, reason, and evaluate these ideas and share your own conclusions!

Let's Banish Critical Thinking, Part 2: Learn

Kyle examined his bookmarks. If he’d printed out all the information he’d found the paper would pile up to well over an inch high. Even though he’d been discerning in the references he noted, the information available was overwhelming and defeating, an obstacle that prevented Kyle from moving past the data collecting stage of his project. Whether he chose the traditional approach and wrote a paper or the technological option of a multimedia presentation, Kyle couldn’t communicate ideas he didn’t yet “own” himself, and the list of bookmarks represented more than he could ever apprehend.

His teacher expected evidence of his learning, but Kyle lacked the know-how that could enable his success. Kyle was a successful student in traditional classrooms, but he did not know how to learn, especially when he was responsible for the process.

As teachers we tend to focus on our teaching and assume students know how to learn. It’s a natural perspective—we teach, students learn. Focusing on learning can seem misdirected because what we’re going to do in the classroom demands our immediate concern—it’s what we describe in the required lesson plans. However, failing to focus on student learning capacity produces the predicament Kyle faced: expectation without enablement.

I suggested in the previous post that we examine thinking as a target. “Memorize” formed the target’s outermost ring. Learning represents a movement toward the target’s center and beyond mere recall. In fact, we’re moving from a relatively straightforward process (rehearse→remember→recall) to more complicated combinations of processes.

Learning often involves four core processes, or four “states” of thinking. (Thinking is more fluid than the term states suggests, but this simplification can help us understand its flow.) Through experience, the brain gains raw sensory data. During comprehension, the brain sorts, labels, and organizes the raw sensory data. Through elaboration, the brain examines the organized data for patterns, recalls relevant prior experiences, and blends the new data with your experiences to construct understanding. During application the brain practices using or expressing the new understanding. There’s much more that could be said just about these core processes (an entire chapter of The Architecture of Learning explores these in depth), but allow me to move on and introduce a related idea.

The influential book 21st Century Skills: Learning for Life in Our Times argues for a greater emphasis on “Learning and Innovation Skills.” Such skills, explain authors Trilling and Fadel, “are the keys to unlocking a lifetime of learning and creative work.”1 We should increase instruction in the skills of learning, not just guide student learning of core subject matter. In other words, we need to place more value and emphasis on teaching students how to self-teach (or self-learn). We need to teach them how to engage learning’s core processes; we need to teach them the thinking skills that enable self-directed learning.

As we explore learning’s core processes in detail, a myriad of related skills emerge. Here’s a partial chart I’ve compiled. (Click on the table to enlarge it.) All these skills either contribute to a core process or engage a combination of learning’s core processes.



Going deeper, learning to learn becomes even more interesting (or complex, depending on your perspective), but what we can actually teach comes into focus. For example, a group of educators in Philadelphia took part of the very first skill (identifying, clarifying, and phrasing questions) and discussed, “What is the range of this skill? What do its initial steps of development look like? What would its fullest expression look like?” After we grappled with these concepts, we considered when instruction for each step might begin and where it might mature to mastery. Here’s what evolved: As we saw this potential scope emerge, the group became excited. For the first time, many of them felt they knew what to teach to equip students to think critically. (I know, I used the term I’m advocating we banish!) My response, and what I still believe, is that we identified, at least in part, the skills we could teach that would equip students to learn independently. Learning is not separate from thinking but dependent on it:
What we know results from what and how we think. Researcher and critical thinking expert Diane F. Halpern explains:

Knowledge is not something static that gets transferred from one person to another like pouring water from one glass to another. It is dynamic. Information becomes knowledge when we make our own meaning out of it…[We] create knowledge every time we learn a new concept.

Educator Laura Erlauer agrees, explaining that thinking processes “allow the brain to thoroughly understand the new concepts and internalize them into meaningful memories.” Learning is a product of thinking.2

Where does that leave us? Here are a few possible conclusions:
  • Learning is more than memorizing. It engages cognitive processes (comprehension, elaboration, application) that extend beyond rehearsal and recall. Learning is powered by thinking, and learning provides new material for thinking. (As one commenter on the last post put it, you have to have something to think about.)
  • Teaching students how to become learners requires helping them develop these cognitive processes and their associated skills/sub-skills.
  • The associated skills possess “steps” of development that provide more specific direction for what we can emphasize in the classroom.
  • Teaching these skills should be our priority. Everything else, such as the specific topics we teach, should be the material students learn through practice in using these skills. In other words, these skills should “drive” the curriculum. That does not mean we do not teach the traditional disciplines, but that the traditional disciplines are a means to the desired end of equipping self-directed learners.
I realize this leaves plenty of unanswered questions, such as:
  • What are the developmental steps for all the other skills?
  • What about problem solving? creativity? reasoning?
  • How can we “cover” the mandated curriculum while teaching students the skills to become self-directed learners?
  • How does teaching students to become self-directed learners aid achievement as measured on standardized testing?
  • Are there approaches we can use that would engage students in utilizing these skills while becoming knowledgeable of new subject matter?
I’ll address some of these in future posts, but honestly, I don’t have answers to all of them. It seems current educational mandates and structures hinder good answers to some of these critical questions (and produce the very problems Kyle faced). Changing direction likely requires a rethinking of current emphases and structures.

But then you probably already knew that.

Here's a Thought: Let's Banish Critical Thinking

I’ve been thinking about thinking lately, and I’ve had it with critical thinking. Note the italics. I’ve had it with the term critical thinking, not the actual practice. From a recent immersion in thinking-related research, I’ve concluded that critical thinking is like the weather: everybody talks about it but few do anything about it.

No arena bandies the term about as widely as education. Few conferences fail to include at least one session devoted to the topic, and book vendors at these events hawk the latest tomes dedicated to it. Educators seem to agree on the need for students to learn to think critically, but that seems to be the end of their consensus. Ask three different educators for their definition of critical thinking and you’re likely to get at least four different ideas, and at least half of them will include a nod to Bloom’s Taxonomy. Somewhere in our history, many of us were convinced that if our questioning climbed a ladder and we called on students whose names we wrote on popsicle sticks and pulled randomly from a styrofoam cup, we were teaching students critical thinking.

Because of the confusion all these preconceived notions create, I propose that we stop talking about critical thinking and instead just think about thinking. To that end, I’ve started referencing a different model. Imagine thinking as a target. As any marksman knows, the center of the target is where you aim if you want the best result. However, though the center of this target represents the ultimate goal, the outer circles are not without value. Let’s examine the first of these outer circles: memorize.


Wait, don’t stop reading! I know memorizing lacks the flash and appeal of the target’s other circles, but our brains do indeed memorize information, sometimes without our consent. For example, I know every lyric to the 70’s classic but somewhat mind-numbing “Funkytown.” I never intentionally sat down and used flash cards to learn the lyrics. They just got stuck in my head, which is one way to define memorizing. We memorize when things get stuck in our heads, on purpose or otherwise.


When educators talk about memorizing, it’s usually with a scowl on their faces and the taste of battery acid on their tongues. Memorizing is so beneath us. We don’t have students memorize anything. Everything we teach is meaningful. It’s all the others—teachers who teach other disciplines—who make students memorize unnecessary information. We’re above such an approach. We climb questioning ladders and pull popsicle sticks, for pete’s sake!


But let’s be honest. Despite the fact that most everything factual can now be found quickly via technology, some information still possesses its greatest value when it’s memorized. At its best, memorizing enables efficiency in thinking and acting. For example, knowing how to spell the words critical and thinking saved me plenty of time in developing this post. If I didn’t know instantly how to spell most of the words I use in writing, I’d probably have far less to say. (I know what you’re thinking: that’d be a bad thing?) Can you imagine trying to compose any significant passage of writing if you had to stop and check your wireless device for the correct spelling of every word?


I once had an experience that provides a picture of what this might be like. My wife and I love going to the theater for live performances. One time, just before the curtain was raised on a new drama, the announcer spoke via the public address system: “Today the role of Countess Calista will be played by Jane Smith, script in hand.” Apparently the lead actress and her understudy were unavailable. Sure enough, Ms. Smith waltzed onto stage with “script in hand,” and read her lines throughout the performance. It was disjointed and distracting. So much so that I can’t even remember the name of play, let alone what it was about. Memorizing has its place, even when technology that can provide the next line or correct spelling exists.


However, at its worse, memorization becomes merely testable material that lacks any use beyond the end of an instructional unit. With such material, its measurability is often its sole benefit, and it’s a benefit for the teacher not the student. Unfortunately it seems that many schools would rather aim for this outermost circle, decreasing the likelihood of hitting any part of the thinking target. But if we aim for and even hit this outermost circle, we have problems. Memorizing, while valuable when engaged selectively, has its limits.


First, students who only memorize remain subject to dogma’s sway. Parroting is evidence of memorizing, and a student who has highly developed memorizing capacity without equally developed processing abilities will tend to repeat the ideas of others, often without understanding.


Second and relatedly, students only equipped to memorize tend to accept without question. Such individuals tend to take the words that fall from the mouths of people they like and repeat them whether they are true or not. Since they lack the ability to process the ideas the words represent, accepting and repeating those words become the individual’s way of “thinking.”


Third, individuals who rely solely on memorizing as thinking cannot entertain or even understand conflicting ideas. That which they’ve memorized becomes their sole reference, so anything new must conform with the previously memorized information.


In short, merely memorizing severely limits an individual. So, while hitting the outermost circle represents one element of mental activity, always aiming there produces individuals I don’t think most schools and teachers would claim as their intended outcome. We need to consider the inner circles (and we will in future posts) and actually teach students the cognitive skills associated with them. Popsicle sticks and questioning variety alone won’t get us there.


Let’s think about thinking—teaching it, increasing it, developing students who actually can do it—but let’s leave our confusing dance with critical thinking behind.

Integrative Thinking, Part 5: Resolution

Salient elements of two opposing ideas are explored for causality while decisions regarding structure (or “architecture”) are delayed to enable form to truly reflect function. These integrative thinking steps lead to the final stage: resolution. (See the previous postings on this topic for information on salience, causality, and architecture.)


In The Opposable Mind, Roger Martin (2007) describes resolution as the “creative resolution of tensions” (p. 47). Opposing ideas contribute traits that merge to generate a new idea. The form created through such a merge establishes the resolution.


In Isadore Sharp’s experience, resolution produces a “system of reinforcing activities,” comprising mid-sized hotels with an intimate feel, superior staff attitude and customer service, consistency in implementation worldwide, and a focus on serving employees. Each element of the “system” strengthens the others to generate a model that thrives (p. 38).


Integrative thinking may be interesting to study, but how does it relate to teaching and learning? We’ll explore this in the next posting, but recent research suggests that increased teacher thinking could do much to improve the quality of instruction and depth of learning in our schools.

Integrative Thinking, Part 3

Integrative thinking considers opposing ideas and borrows from each to construct an idea superior to the original opposing ideas. Salience is one of the thinker’s considerations in processing the opposing ideas. Salience, or relevance, produces a list of desirable traits/characteristics/features that are desired in a new idea.

In The Opposable Mind, Roger Martin (2007) suggests causality continues guiding integrative thinking. Once salient features from each idea have been identified, the thinker explores relationships between them. The relationships, or connections, between the ideas aid the thinker in understanding the give-and-take of each opposing idea and alternatives between the extremes that may yield a better solution.


Martin (2007) illustrates causality by continuing to explore Isadore Sharp’s founding of the Four Seasons line of hotels. Sharp noted an obvious relationship between hotel size and amenity offerings—larger hotels offered more amenities. But did it have to be this way? Could a smaller hotel offer an increased number of amenities and remain profitable? Another causal connection provided a position between the extremes.


Sharp knew that employees more consistently provided outstanding service to hotel guests if the employees were served well by management. The concept of high quality service became the defining characteristic of the Four Seasons hotels, both at the management to employee and employee to guest levels. And that level of service justified higher lodging rates, rates guests were willing to pay because they felt they received service worthy of the monetary outlay (p. 34-37).


Considering causality provided a superior idea to either of the original opposing ideas. Connecting concepts prompted Sharp to explore how altering input (quality of service at all levels) could generate a superior solution (small hotels with great amenities made profitable, in part, by the provided level of service).


Returning to our challenge, what are the causal connections between the salient features of hands-on teaching vs. lecturing? Do these causal connections prompt ideas of better approaches to teaching—ideas that feature elements of both but structured in such a way that the teaching is improved? Play with these thoughts and see what develops.


In the next posting, we’ll explore the third feature of integrative thinking: architecture.

Integrative Thinking, Part 2: Salience

In The Opposable Mind, Roger Martin (2007) defines integrative thinking:

The ability to face constructively the tension of opposing ideas and, instead of choosing one at the expense of the other, generate a creative resolution of the tension in the form of a new idea that contains elements of the opposing ideas but is superior to each.
Notice the time factor. Integrative thinking is a form of creative thinking, and creativity requires a pause between initially getting information and moving to application. I often use the term percolate to describe this pause, as in, “I don’t know yet. I need to let the idea percolate.”

During this pause, integrative thinking rejects neither opposing idea. Instead, it explores each and constructs something new—something that possesses traits of each idea but generates a result/solution better than either opposing idea.

This exploration begins as the thinker analyzes the opposing ideas to identify “salient” (i.e., relevant, important) elements (p. 29). What about Idea A is noteworthy? potentially beneficial? logical? accurate? The same analysis is made of Idea B, the opposing idea. This analysis produces a list of desirable traits/characteristics/features that are desired in a new idea.

To illustrate this analysis for salience, Martin presents Isadore Sharp’s story. When Sharp entered the hotel business, two models dominated. Hotels were either large and offered a myriad of amenities or small and offered just the necessities. Pulling from both models, Sharp designed a hotel with the amenities frequent travelers needed and an emphasis on personal service. This model became the Four Seasons line of hotels. “Rather than choose one of the existing models and accept the downside it entailed, Sharp used his opposable mind to hold the two models in his head, roll them around, and design a creative resolution of the tension between them” (p. 31).


Challenge yourself to apply this factor of integrative thinking. Choose two opposing ideas (e.g., teaching through hands-on activity vs. teaching through lecture). Can you analyze the ideas, identifying salient elements of each? Write a list and keep it handy. In the next posting, we’ll explore the second feature of integrative thinking: causality.

“Integrative Thinking”: Part 1

Everyone has opinions. Some are informed opinions. Others are judgements reached in the absence of evidence. For example, much to my wife’s dismay, I know that I do not like shrimp. I also claim that I do not like calamari. One informed opinion (I’ve unfortunately tasted shrimp) and one judgement formed without evidence (I’ve never actually tasted calamari).

Fine, suggests Roger Martin in his book The Opposable Mind, but can you consider two opposing ideas at the same time. While it may be difficult for me to think simultaneously that I do and do not like shrimp, I could potentially consider two sides of an argument. For example, government spending is a means of economic stimulus vs. government spending fails as a means of economic stimulus. The ability to hold such two opposing ideas in one’s mind often leads to “a synthesis that is superior to either opposing idea” (Martin, 2007, p. 6).


Martin refers to this ability as “integrative thinking” (p. 6), and claims that such thinking can produce insights that holding to only one thought cannot. Furthermore, Martin claims integrative thinking leads to better solutions than considering only one idea. In his research, leaders who possessed integrative thinking made significant breakthroughs that benefitted their organizations.


What, then, are the attributes and components of integrative thinking? and how can we help students develop this worthwhile capacity? We’ll be exploring these ideas in future postings.


By the way, Dr. Ginger Campbell, friend and host of the Brain Science Podcast, was featured in several Alabama newspapers recently. Check out the article here.
