“If you can get only one book this year, make it this one.” That is quite an endorsement for a book from one of my favorite blog sites, Garr Reynold’s Presentation Zen.
The book is Brain Rules by Dr. John Medina, a developmental molecular biologist. His professional title can be intimidating, but don’t worry, his writing is accessible to non-professionals. In fact he has built a very nice website on the topic - www.brainrules. net. It’s a good thing he did that since I can’t find a copy of the book in our bookstores.
Brain Rules distills the findings of research into the human brain and applies them to learning and presentations (teaching). His website has a succinct definition of “brain rule” - It’s one thing scientists know for sure about how our brain works.
Garr Reynolds used the principles in the book to make a slide presentation on the book - Takeaways and Quotes from Brain Rules. That’s a neat way of delivering the message.
Most of the 12 Brain Rules have been used and advocated by good presentors and educators. What Dr. Median has done is to present their basis in what scientists have learned about how our brain works. But by way of caveat, the best neuroscientists caution us that although we know much more today about the brain, there is even more that we do not yet know.
Here are the 12 Brain Rules as found in his website, without commentary:
Rule 1: Exercise. Exercise boosts brain power.
Rule 2: Survival. The human brain evolved too.
Rule 3: Wiring. Every brain is wired differently.
Rule 4: Attention. We don’t pay attention to boring things.
Rule 5: Short-term memory. Repeat to remember.
Rule 6: Long-term memory. Remember to repeat.
Rule 7: Sleep. Sleep well, think well.
Rule 8: Stress. Stressed brains don’t learn the same way.
Rule 9: Sensory integration. Stimulate more of the senses.
Rule 10: Vision. Vision trumps all other senses.
Rule 11: Gender. Male and female brains are different.
Rule 12: Exploration. We are powerful and natural explorers.
This list of rules is too skimpy and act more as “teasers.” But they remind me of other books and articles I have read about effective teaching and learning, and I look forward to finding a copy of Brain Rules soon.
In the meantime, we can get a sense of what to expect through these excerpts from the author’s introduction:
My goal is to introduce you to 12 things we know about how the brain works. I call these Brain Rules. For each rule, I present the science and then offer ideas for investigating how the rule might apply to our daily lives, especially at work and school. The brain is complex, and I am taking only slivers of information from each subject—non-comprehensive but accessible.
• For starters, we are not used to sitting at a desk for eight hours a day. From an evolutionary perspective, our brains developed while working out, walking as many as 12 miles a day. The brain still craves the experience, especially in sedentary populations like our own. That’s why exercise boosts brain power in such populations. Exercisers outperform couch potatoes in long-term memory, reasoning, attention, problem-solving tasks, and more. I am convinced that integrating exercise into our eight hours at work or school would only be normal.
• As you no doubt have noticed if you’ve ever sat through a typical PowerPoint presentation, people don’t pay attention to boring things. You’ve got seconds to grab someone’s attention, and only 10 minutes to keep it. At 9 minutes and 59 seconds, something must be done quickly—something emotional and relevant. Also, the brain needs a break. That’s why I use stories in this book to make many of my points.
• Ever feel tired around 3 o’clock in the afternoon? That’s because your brain really wants to take a nap. You might be more productive if you did: In one study, a 26-minute nap improved NASA pilots’ performance by 34 percent. Even so, the brain isn’t resting while it sleeps. It is surprisingly active. And whether you get enough rest affects your mental agility the next day. Sleep well, think well.
• Most of us do more forgetting than remembering, of course, and that’s why we must repeat to remember. When you understand the brain’s rules for memory, you’ll see why I want to destroy the notion of homework.
Although he calls them brain “rules” the author does not want us to treat his ideas as prescriptions. Instead, he says that his book is a call for real world research. He explains:
I occasionally would run across articles and books that made startling claims based on “recent advances” in brain science about how to change the way we teach people and do business. And I would panic, wondering if the authors were reading some literature totally off my radar screen. I speak several dialects of brain science, and I knew nothing from those worlds capable of dictating best practices for education and business …
There was no need to panic. You can responsibly train a skeptical eye on any claim that brain research can without equivocation tell us how to become better teachers, parents, business leaders, or students. This book is a call for research simply because we don’t know enough to be prescriptive. It is an attempt to vaccinate against mythologies like the “Mozart effect,” left brain/right brain personalities, and getting your babies into Harvard by making them listen to language tapes while they are still in the womb.
His introduction winds up with the following provocative propositions:
What we know about the brain comes from biologists who study brain tissues, experimental psychologists who study behavior, and cognitive neuroscientists who study how the first relates to the second. Evolutionary biologists have gotten into the act as well. Though we know precious little about how the brain works, our evolutionary history tells us this: The brain appears to be designed to solve problems related to surviving in an unstable outdoor environment, and to do so in nearly constant motion. I call this the brain’s performance envelope.
Each subject in this book—exercise, survival, wiring, attention, memory, sleep, stress, sense, vision, gender, and exploration—relates to this performance envelope. Motion translates to exercise. Environmental instability led to the extremely flexible way our brains are wired, allowing us to solve problems through exploration. Learning from our mistakes so we could survive in the great outdoors meant paying attention to certain things at the expense of others, and it meant creating memories in a particular way. Though we have been stuffing them into classrooms and cubicles for decades, our brains actually were built to survive in jungles and grasslands.
I am a nice guy, but I am a grumpy scientist. For a study to appear in this book, it has to pass what some at The Boeing Company (for which I have done some consulting) call the MGF: the Medina Grump Factor. That means the supporting research for each of my points must first be published in a peer-reviewed journal and then successfully be replicated. Many of the studies have been replicated dozens of times…
What do these studies show, viewed as a whole? Mostly this:
If you wanted to create an education environment that was directly opposed to what the brain was good at doing, you probably would design something like a classroom. If you wanted to create a business environment that was directly opposed to what the brain was good at doing, you probably would design something like a cubicle. And if you wanted to change things, you might have to tear down both and start over.
In many ways, starting over is what this book is all about.
Whenever I read books about how the brain works, and the implication for how we learn and teach, I am faced with a dilemma. I am part of the campaign for Education For All as president of E-Net Philippines and as board member of GCE, the Global Campaign for Education. But the premises on which the current school systems are based are being challenged by the findings into how our brains work and learn.
We need to continue campaigning for all children to have access to quality basic education, within the present system. But we can not ignore or postpone the need to reform our schools and learning systems to take advantage of the findings into how we learn better, if not best.
But how to do both? I am reminded of the metaphor from another context, that it will be like repairing a plane while in flight, or a ship while sailing on the sea.
Perhaps these ideas and their methodological consequences have better chances of being tested in the process of constructing alternative learning systems or ALS. If so, then ALS may eventually also mean advanced learning systems.
