wow - very much what my detox was today..

how to hasten being and model it, by doing.. am i legit in that? or am i bunk in the myth of tomorrow...?
i think i'm bunk in the myth of tomorrow - except for the idea of equity. i feel i need to be doing the doing for equity sake.

What part of “VAM doesn’t work and so don’t use it” escapes the intellect of our elected officials?…

  However, we have to remember that this has never been about developing a valid and reliable system of assessment for classroom teachers. This is about redistributing tax dollars to the testing and data management companies that continue to finance our elected officials who put policies in place that continue to siphon tax money right back to the testing companies
National Education Policy Center (NEPC) in a review of Gates Foundation funded VAM research stated “that a teachers’ value-added for the state test is not strongly related to her effectiveness in a broader sense. Most notably, value-added for state assessments is correlated 0.5 or less with that for the alternative assessments, meaning that many teachers whose value-added for one test is low are in fact quite effective when judged by the other. ” And in even simpler terms.  Value Added Measurement systems will incorrectly rank teachers one out of every three times—at best

Thoughtful, provocative piece by @nancyflanagan "If You Would Take a Bullet for a Child . . ."… #edreform #rechat

While I empathize with the frustration and impatience, any national movement must be driven by a very broad base of goals and participants; a half-baked national teachers' protest might serve parents who are angry about what's happened to their children without accruing any power for teachers who want to make decisions about their own work. Teachers can't protest effectively unless administrators, school boards, parents and community leaders join forces in a unified movement 
#6) So--ultimately, this question is about strength in numbers. Why is ALEC is pumping out "parent trigger" legislation (where the parent "input" ends once the public school is "disrupted")? When teachers, school leaders and public schools are divided from the people they serve--students, parents and community members--"reformers" win. When the wisdom of good practice--the things parents and educators really want for kids--meets the bulwark of policy, it had better be a tsunami. A single, vocal and articulate teacher (or parent--or administrator) can only be a beacon, not a pathway. 
Perhaps the teachers in Finland can be more proactive, because their culture and leadership doesn't keep them in survivor mode.

New design for a basic component of all computer chips boasts the highest ‘carrier mobility’ yet
Saraswat believes that the semiconductor industry is already planning a move toward germanium circuits. “The choice is to scale the silicon transistor without any performance gains — just get to higher packing density — or get higher packing density as well as better performance,” he says. “And it’s fairly clear that the industry will go for high-strain germanium.”
The MIT researchers’ work was supported by the U.S. Defense Advanced Research Projects Agency and the Semiconductor Research Corporation.At the IEEE’s International Electron Devices Meeting (IEDM) in December, researchers from MIT’s Microsystems Technology Laboratories (MTL) presented a p-type transistor with the highest “carrier mobility” yet measured. By that standard, the device is twice as fast as previous experimental p-type transistors and almost four times as fast as the best commercial p-type transistors.
Like other experimental high-performance transistors, the new device derives its speed from its use of a material other than silicon: in this case, germanium. Alloys of germanium are already found in commercial chips, so germanium transistors could be easier to integrate into existing chip-manufacturing processes than transistors made from more exotic materials.
The new transistor also features what’s called a trigate design, which could solve some of the problems that plague computer circuits at extremely small sizes (and which Intel has already introduced in its most advanced chip lines). For all these reasons, the new device offers a tantalizing path forward for the microchip industry — one that could help sustain the rapid increases in computing power, known as Moore’s Law, that consumers have come to expect.
Judy Hoyt, a professor of electrical engineering and computer science; her graduate students Winston Chern, lead author on the new paper, and James T. Teherani; Pouya Hashemi, who was an MIT postdoc at the time and is now with IBM; Dimitri Antoniadis, the Ray and Maria Stata Professor of Electrical Engineering; and colleagues at MIT and the University of British Columbia achieved their record-setting hole mobility by “straining” the germanium in their transistor — forcing its atoms closer together than they’d ordinarily find comfortable. To do that, they grew the germanium on top of several different layers of silicon and a silicon-germanium composite. The germanium atoms naturally try to line up with the atoms of the layers beneath them, which compresses them together.

@jonbecker Actually, "know" is a euphemism. More edu-speak, promo-speak, huh?-speak in that report than freshman-trying-too-hard paper.
