Challenging authority and pushing the bounderies of change to tradition drives necessary change. Although it certainly leads to some stressful moments, I thrive off bringing dynamic and sometimes radical ideas to the table. I can see this being difficult if you have no support from your peers or your administration, but that is why we socially network..;).

In particular, it seems to me, that we should try to get children to learn use the “T-test” method, which is a simple statistical test, yet which handles huge ranges of situations. Also they should understand using square roots to assess variations. Example: Basketball scores are frequently not statistically significant!

A key skill in mathematics, if not the key skill, is abstraction: the ability to abstract away from real world objects, and manipulate these abstractions to draw deep results, is vital. Abstraction is fundamental to mathematics; it is what gives mathematics both its power and its scope; it is the mechanism by which higher mathematics is built upon elementary mathematics. Abstraction and abstract thinking is one of the core skills that mathematics education should be imparting - and yet it is completely ignored by these math syllabuses.

a core skill that mathematics education should imbue, logical structured thought and a systematic approach to dealing with abstract objects, is being ignored

The purpose of presenting the content isn't so that it can be evaluated by some authority but rather to place it in focus, in context, so it can be reflected on by the creator (and his or her peers).

The skills are there, the tech's there, all that's missing is the desire of those not in the know to learn.

I personally think that community as such is vastly overrated - community (group) implies a sort of conformity with which I am not comfortable. But content is also vastly overrated, so Leinonen. What do I think should be emphasized? Choice. Control. Autonomy.

instead of the entire apparatus we fund today, we instead fund several thousand people with really good salaries and tell them to go forth and provide education to whomever wants it. Add to that perhaps personal coaches hired by local communities. Imagine... Jess Jarvis, Buzz Machine, May 1, 2007. [Link]

How many of America’s uninsured could afford to buy coverage if they wanted to? The research, published last year in the Journal of Health Economics, found that as much as three-quarters of the uninsured population may be able to afford its own insurance. Even under the grimmest assumptions, one-quarter of the uninsured can already afford to buy coverage.

How do I know what freedoms I want until I’ve experimented? How can I even explain them until I’ve experienced them? Should the progress of tomorrow really be shackled by registering as law the prejudices and errors of today?

The same story about CDs is the one we used to hear about books all the time. You know, the need for an archive, the need for the physical feel of a book, that sort of thing. The other side is that the market for CDs is falling through the basement, and while there remains a market, it is increasingly one for nostalgia buffs only

At its most extreme, such a behavioral addiction dominates a person's life. They need the activity, and they'll sacrifice nearly anything – long term plans, the company of people, even work in order to have it.

In 1979, the top 1% received about 9.3% of US income but paid 18.3% of all income taxes collected, while the middle class received 15.8% of US income but paid10.7% of all income taxes collected. As of 2004, the top 1% received 16.3% of income and paid 37% of all income taxes, while the middle class received 13.9% of income and paid only 4.7% of all income taxes. And let’s get real about “receiving income”. These people generated wealth.

Learning isn’t about being productive or being able to compete in today’s world or even being entrepreneurial. It is about making choices for yourself, being in control of your own destiny, about leading a good life, being the best you can be, however you define ‘good’ and ‘best’ to be.

Slowly start raising the marginal tax rate from around 30% up to 100% on the top earners and watch our economy slow down to a European crawl. People will take less risk for the promise of reward (being context-successful). The bar will be lowered for all. Rent seeking will increase (EADS management anyone?)

But as tax rates rise beyond some critical level (which seems like a fascinating topic for inquiry), the rich will channel more effort away from income-generating activities, ie focusing on family, personal growth, charity, political ambition.
The effect is to prevent risk-taking by those most able to take intelligent risks that create growth.

Networks often show power laws. They can be caused by the "rich get richer" effect, also known as "preferential attachment," where nodes gain new connections in proportion to how many they already have. That means some nodes end up with many more connections than others. The phenomenon is well known, but had been assumed to be just a fundamental property of networks.
