Journal: Whither Opportunity? Rising Inequality and the Uncertain Life Chances of Low-Income Children, New York: Russell Sage Foundation
Excerpt from abstract:
In this chapter I examine whether and how the relationship between family socioeconomic characteristics and academic achievement has changed during the last fifty years. In particular, I investigate the extent to which the rising income inequality of the last four decades has been paralleled by a similar increase in the income achievement gradient. As the income gap between high- and low-income families has widened, has the achievement gap between children in high- and low-income families also widened?
The answer, in brief, is yes. The achievement gap between children from high- and low-income families is roughly 30 to 40 percent larger among children born in 2001 than among those born twenty-five years earlier. In fact, it appears that the income achievement gap has been growing for at least fifty years, though the data are less certain for cohorts of children born before 1970. In this chapter, I describe and discuss these trends in some detail. In addition to the key finding that the income achievement gap appears to have widened substantially, there are a number of other important findings.

How about better parents? — from The New York Times by Thomas Friedman
Excerpt:
In recent years, we’ve been treated to reams of op-ed articles about how we need better teachers in our public schools and, if only the teachers’ unions would go away, our kids would score like Singapore’s on the big international tests. There’s no question that a great teacher can make a huge difference in a student’s achievement, and we need to recruit, train and reward more such teachers. But here’s what some new studies are also showing: We need better parents. Parents more focused on their children’s education can also make a huge difference in a student’s achievement.
…
To be sure, there is no substitute for a good teacher. There is nothing more valuable than great classroom instruction. But let’s stop putting the whole burden on teachers. We also need better parents. Better parents can make every teacher more effective (emphasis DSC).
From DSC:
Agreed.

HTML5: Briefing notes for journalists and analysts — from html 5 Doctor by Bruce Lawson
Excerpt:
Your friendly neighbourhood doctors are often contacted by journalists and analysts who have questions about HTML5, usually from a consumer of business perspective. This is great, as we spend many more hours every week mutely shaking our heads while reading the ill-informed columns from journalists or analysts who haven’t contacted us.
Here are the most common questions we’re asked, with non-technical answers. Journos – you’re welcome to use these answers (a citation would be nice but isn’t required).
We’ll add new questions and answers as they are asked.

Ask Marcus Buckingham anything you want — from Daniel Pink and Marcus Buckingham
Excerpt:
In the last decade, millions of people have come around to the idea that we’re better off building on our strengths instead of constantly trying to fix our weaknesses (emphasis DSC). That change in perspective is due, in no small part, to Marcus Buckingham.
Now you’ll have a chance to ask Marcus anything you want on the next episode of Office Hours — Friday September 16 at 11am EDT.
From DSC:
What resonates with me about Marcus’ message is one of the principles that stuck with me from my economics studies; and that is, everyone benefits when we do what we do best. Again, as I age, I realize how true this is. We all have strengths and weaknesses — but the results from putting our energies into our strengths are far greater (for everyone we interface with) than the results are when we try to make small, incremental (at best) changes to our weaknesses. The Bible also talks about this concept when it talks about parts of a body — that we play different roles…that we have different gifts and abilities but none of us are the whole body in itself.
This same concept relates to why I feel so strongly about the use of teams of specialists in the creation and delivery of content for K-12 education, higher education, and in corporate training-related efforts. No one can do it all anymore.

Yale finds cause of age related memory loss and finds it may be reversible — from NextBigFuture.com
Excerpts (emphasis DSC):
A new study published July 27 in the journal Nature shows that the neural networks in the brains of the middle-aged and elderly have weaker connections and fire less robustly than in youthful ones. Intriguingly, note the scientists, the research suggests that this condition is reversible.
…
Arnsten said that the aging prefrontal cortex appears to accumulate excessive levels of a signaling molecule called cAMP, which can open ion channels and weaken prefrontal neuronal firing. Agents that either inhibited cAMP or blocked cAMP-sensitive ion channels were able to restore more youthful firing patterns in the aged neurons. One of the compounds that enhanced neuronal firing was guanfacine, a medication that is already approved for treating hypertension in adults and prefrontal deficits in children, suggesting that it may be helpful in the elderly as well, note the researchers.
Arnsten’s finding is already moving to the clinical setting. Yale School of Medicine is enrolling subjects in a clinical trial testing guanfacine’s ability to improve working memory and executive functions in elderly subjects who do not have Alzheimer’s disease or other dementias.

From Brett Victor’s “Kill Math” page
The power to understand and predict the quantities of the world should not be restricted to those with a freakish knack for manipulating abstract symbols.
When most people speak of Math, what they have in mind is more its mechanism than its essence. This “Math” consists of assigning meaning to a set of symbols, blindly shuffling around these symbols according to arcane rules, and then interpreting a meaning from the shuffled result. The process is not unlike casting lots.
This mechanism of math evolved for a reason: it was the most efficient means of modeling quantitative systems given the constraints of pencil and paper. Unfortunately, most people are not comfortable with bundling up meaning into abstract symbols and making them dance. Thus, the power of math beyond arithmetic is generally reserved for a clergy of scientists and engineers (many of whom struggle with symbolic abstractions more than they’ll actually admit).
We are no longer constrained by pencil and paper. The symbolic shuffle should no longer be taken for granted as the fundamental mechanism for understanding quantity and change. Math needs a new interface.
