ISTE 2011 Opening Keynote Address

It's often said that people use only 10 percent of their brain capacity. It's also said that every person has either a “left-brain” or a “right-brain” personality. Dr. John Medina, a developmental molecular biologist, research consultant and author of Brain Rules: 12 Principles for Surviving and Thriving at Work, Home and School, begs to differ.

In his opening remarks before a packed auditorium of educators and IT decision makers attending the International Society for Technology in Education's 32nd annual conference and exposition in Philadelphia, Medina scoffed at those oft-repeated theories. As an affiliate professor of bioengineering at the University of Washington School of Medicine in Seattle and director of the Brain Center for Applied Learning Research at Seattle Pacific University, Medina said he's often asked how brain science can be leveraged to influence how we teach people.

“I'm fairly skeptical about applying anything in the neurosciences to formal education,” Medina told conference attendees. “We just don't know very much, in real terms, about how the brain actually works.” What's more, “every brain is wired differently and learns in ways that are unique to that wiring.”

Still, Medina had plenty to say about the state of education today and the ways in which technology might shape learning going forward.

Rules to Live By

In Brain Rules, a 2008 New York Times bestseller, Medina draws on his years of research into the genes involved in human brain development and the genetics of psychiatric disorders to identify and explain 12 rules that he says dictate how the human mind reacts to and organizes information. The rules can be summarized as follows:

• Exercise: Exercise boosts brain power.

• Survival: The human brain has evolved.

• Wiring: Every brain is wired differently.

• Attention: Humans don't pay attention to boring things.

• Short-Term Memory: Our brains repeat to remember.

• Long-Term Memory: And, they remember to repeat.

• Sleep: If people sleep well, they think well.

• Stress: Stressed brains don't learn the same way.

• Sensory Integration: Brains like stimulation, from multiple senses.

• Vision: Vision trumps all other senses.

• Gender: Male and female brains are different.

• Exploration: People are powerful and natural explorers.

For his keynote address, “Brain Rules for Education,” Medina focused on brain rule No. 4: Humans don't pay attention to boring things.

“We know the human brain's evolutionary performance envelope: The human brain appears to have been designed to solve problems related to surviving in an outdoor setting … and to do so in near-constant motion,” Medina explained. “So even though we don't know squat about how the brain actually works, if you wanted to design a learning environment that is naturally opposed to what the brain is meant to do, you'd design a classroom. For business, you'd design a cubicle.”

If you want to change things, “you have to be willing, intellectually, to start over,” he said.

Digging deeper, Medina likened the human brain to a series of roadways. “All human brains are wired identically at the interstate level,” he said, “but all human learning occurs in the alleyways and the boulevards.” He added that learners need to create a database where they can store memorized information, but they also must be given the opportunity to improvise how they use that information.

“Any education environment that only emphasizes one or the other is failing the human brain,” Medina continued. “If all you do is create a database and memorize something, you are in danger of creating robots. If all you do is improvise, you are in danger of creating kids who only play air guitar. You need to have both a database and the ability to improvise off of it.”

Medina also touched on theory of mind (ToM), a concept that David Premack and Guy Woodruff described in a 1978 journal article as enabling “one to understand that mental states can be the cause of – and thus be used to explain and predict – others' behavior.”

Medina described ToM as the “ability to appear inside someone else's head and understand the reward and punishment systems [that drive them using] purely nonverbal cues,” adding that it gives teachers “the talent to be excellent teachers.”

In a nod to his audience, Medina concluded his remarks by acknowledging that today's teachers frequently work with technology and he wondered if technology would ever be equipped with ToM. To be as effective as teachers, he added, ToM-enabled hardware, software and other learning tools would have to accomplish three things:

• involuntarily detect that a student is puzzled;
• determine where the learning “owie” (that is, gap) lies;
• adapt in situ (and on the fly) the learning lesson so that the owie can be addressed and corrected.

Whether this would be a good or bad thing is a question Medina left open for the audience to decide.
