Happy New Year!
Sitting at home again, as we have done for many years... we'll make it to midnight only because we're waiting up for our youngest son!I've often said that learning is important because the world is a fascinating place. As we hear over and over again about the 10 best this of the year and the ten worst that of the decade, NASA puts things in perspective.
The Hubble telescope provides us with this image of hundreds of thousands of stars moving about in the globular cluster M13, one of the brightest globular clusters in the northern sky. It can be found in the winter sky in the constellation Hercules, and can even be seen with the unaided eye under dark skies.
M13 is home to over 100,000 stars and is located at a distance of 25,000 light-years. In other words, the light in the picture left these stars in 22991 BCE! (For historical perspective, Abraham was ready to sacrifice Isaac in around 1800 BCE. Where will you be in 22991 CE?)
These stars are packed closely together in a ball approximately 150 light-years across, and they spend their entire lives whirling around in the cluster. Near the core, the density of stars is about a hundred times greater than the density in the neighborhood of our sun. These stars are so crowded that they can slam into each other and form a new star, called a "blue straggler." The brightest reddish stars in the cluster are ancient red giants. These aging stars have expanded to many times their original diameters and cooled. The blue-white stars are the hottest in the cluster.
M13 is one of nearly 150 known globular clusters surrounding our Milky Way galaxy. Globular clusters have some of the oldest stars in the universe. Scientists believe they formed before the disk of our Milky Way, so they are older than nearly all other stars in our galaxy including our own sun.

Surviving the Technological Alteration of the Modern Mind
For years we’ve been hearing about the differences between Digital Natives (under 25), who have good tech skills, and Digital Immigrants (their parents), who have weaker tech skills. Small has studied the neural networks of the two groups, and finds that the Digital Natives have much less development in those that control social interaction.
He spoke of the Natives’ relationship to technology is personal, and had us do an experiment exchanging cell phones while we monitored our emotions. For those of us who only turn on our phones when making a call it wasn’t too exciting, but when I replicated the experiment at a faculty meeting, the younger faculty clearly felt the anxiety of disconnection and potential loss of privacy.
No real news here, our brains are changing moment to moment, with neural circuits strengthening with use and weakening with disuse. Giving teachers everywhere hope, Small told us that young brains are missing empathy not because kids are naturally rude, or that societal civility is on the decline, but because that part of their brains has not yet developed.
By adolescence, 60% of connections are pruned, and in a Darwinian twist, between the ages of 8 and 18 is tech time. Our kids have been born with access to limitless information, 24 hour news and entertainment, but with less time for face to face interactions and thus are slowed in their development of empathy and complex reasoning skills.
With social networking (i.e. Facebook, MySpace, Twitter), they are aware all the time of what everyone is doing, which leaves little time for reflection. As they are constantly reacting to others, their individuality and creativity are stifled. One of my favorite phrases to hear at Nora from kids just sitting around is “I’m bored,” because it means they’re having to create something out of nothing, rather than thoughtlessly respond to external stimuli.
Technology develops the Dopamine pathways which are precursors to addiction. In a 2007 Harris poll, 8.5% of college students showed multiple signs of addiction, including escaping problems through playing games, lying about play length, sensitization to fighting stimuli. The inflamation of these neural pathways is a major reason for Alzheimer’s Disease.
In one of Dr. Small’s studies on these neural pathways, he studied the effect of gaming on face to face interactions. Digital immigrants were better able to rapidly identify emotions than digital natives, who were only able to identify happy faces faster than angry, unless the face displayed violent emotions.
The connection with ADHD is not certain. Does video gaming cause the brain to display symptoms of ADHD, or do people with ADHD gravitate to the fast-paced stimulation of video games? Studies are ongoing.

Learning and the Brain
Mara and I are just back (at 11 pm last night) from the Learning and the Brain Conference at MIT, where we spent three solid days in workshops. We not only learned about cognitive overload, we experienced it! As I unpack my notes I'll have more to say, but three big take-aways for our practice as teachers, students, parents, and humans, are:-our brains need quiet time, away from the noise and stimulation of our culture, in order to solidify memory and learning,
-sleep is critical to our ongoing brain development,
-the neural structure of our brains is changed by our cultural stimulation, for which the best antidote is reading (books, not screens),
I'll have more, but right now I have to dig out from three days of missed emails! But later today I promise myself that I'll take a two-minute meditation break.

More Obama-this time, health care
Lest the wingnuts drive us to think that healthcare is just fine in America, our small business is facing a 20% increase in premiums next year. Tuition went up 2%. You can do the math.
Our broker says that 20% is pretty good... one of our small school compatriots is seeing a 76% increase in their premiums.
Our faculty's average age did not change, nor did any of us have catastrophic illnesses.
My choices: increase the teacher's contribution, weaken the plan we offer, fire all the old teachers and replace them with young teachers.
And we're just one, small, business. Maybe that's why we get hit so hard, where are we going to go? Something needs to be done.
We Survived the Indoctrination!
"But at the end of the day, we can have the most dedicated teachers, the most supportive parents, and the best schools in the world – and none of it will matter unless all of you fulfill your responsibilities. Unless you show up to those schools; pay attention to those teachers; listen to your parents, grandparents and other adults; and put in the hard work it takes to succeed. "
"And no matter what you want to do with your life – I guarantee that you’ll need an education to do it. You want to be a doctor, or a teacher, or a police officer? You want to be a nurse or an architect, a lawyer or a member of our military? You’re going to need a good education for every single one of those careers. You can’t drop out of school and just drop into a good job. You’ve got to work for it and train for it and learn for it."
"...at the end of the day, the circumstances of your life – what you look like, where you come from, how much money you have, what you’ve got going on at home – that’s no excuse for neglecting your homework or having a bad attitude. That’s no excuse for talking back to your teacher, or cutting class, or dropping out of school. That’s no excuse for not trying."

The latest from the Fringe
Oh well, we'll certainly allow our students to listen to the president during lunch on Tuesday, and hope that they take his message of hard work and accomplishment to heart. That, after all, is part of our mission as a school and as parents. And the further some folks move their kids to the fringe, the more room there is for our kids at the top!

Zero to One Hundred in one day
After spending three weeks on Cape Cod with my 82 year old father, I'm back in the saddle here at The Nora School preparing for the new school year. Even after doing this for 18 years, I'm amazed at the amount of work that's needed to prepare the building, the faculty, and the families for the upcoming term.
Living life at the pace of an 82-year-old retiree on the Cape certainly is relaxing! Reading, an occasional trip to the beach or the golf course, having all afternoon to prepare dinner... life could hardly be more placid. Returning to school, needing to hire new teachers to manage our over enrollment, going to board meetings of other institutions, having the new bus painted and lettered, getting new lawn furniture, removing the rubble of summer cleanup, preparing for faculty in-service, and planning the creation of a new school community when students arrive, all takes a huge effort, and offers a stark contrast to reading Michael Connolly on the beach!
Perhaps this intensity is now compressed due to my desire to spend time free time with my father and give my sisters a break. Not having spent much time during the winter, spring, and summer breaks to manage the detritus of school life (such as digging out my office) means that when I am here the amount that needs to be done is fairly daunting.
Nonetheless, the world is an amazing place, full of surprises, and in a few days we'll again have the privilege of sharing all these wonders with young people. While my office will probably always be a bit of a mess, my hope is that it goes along with my curiosity and enthusiasm for learning and sharing.
