    "In his new book, Professor Keith Taber reassures practicing and training science teachers, as he explores a range of issues faced by secondary school educators and discusses strategies for teaching the nature of scientific knowledge, making practical work effective and challenging young scientists. Throughout the academic prose, Professor Taber reflects on the nature of scientific knowledge in science education encouraging creating narratives, challenging misconceptions, and exploring principles of constructive teaching. The book continues with exploring specific challenges, such as teaching electrical circuits to lower secondary school students, along with a chapter dedicated to supporting gifted students who excel at the subjects."

    A team of physicists led by Caltech's David Hsieh has discovered an unusual form of matter-not a conventional metal, insulator, or magnet, for example, but something entirely different. This phase, characterized by an unusual ordering of electrons, offers possibilities for new electronic device functionalities and could hold the solution to a long-standing mystery in condensed matter physics having to do with high-temperature superconductivity-the ability for some materials to conduct electricity without resistance, even at "high" temperatures approaching -100 degrees Celsius.

    "Here at BA Central I see a lot of truly ridiculous conspiracy theories. Over the years there's been the Moon Hoax, various asteroids NASA was covering up that would hit the Earth (or wipe us out somehow via electricity), and of course the end of the Earth over and over and over again. Yet happily, we're still here. Yet sadly, so are these silly theories."

Adam Kirk Edgerton: Why I Quit Teaching - 53 views

  • Who orders books? A classroom teacher. Who writes the curriculum? A classroom teacher. Who handles discipline? A classroom teacher.
  • Evaluations are done by peers, and the tools are developed by teachers. Teachers are hired by other teachers. There are no outside consultants, no central office administrators, and no superintendents.
  • Let it be the person who pays the electrical bill, who makes sure everyone gets paid, who is a sounding board for teachers. Let it be someone who still has to lesson plan, grade and walk in front of a room of children every day and figure out what's best for them, one day at a time.

  • If we continue to treat our teachers like children, what will become of our children?
  • I quit teaching because I was tired of feeling powerless. Tired of watching would-be professionals treated as children, infantilized into silence. Tired of the machine that turns art into artifice for the sake of test scores. Tired of being belittled, disrespected and looked down upon by lawyers, politicians, and decision-makers who see teaching as the province of provincials, the work of housewives that can be done by anyone.

    "If we continue to treat our teachers like children, what will become of our children?" Although this article is very confrontational, it does offer some solution-focused thinking. Teachers should be pushing our profession in these ways--prompting dialogue and debate among our communities and our faculties.

Startup turns carbon dioxide into fuels - 1 views

shared by Jac Londe on 18 Jun 12 - No Cached
  • Today, carbon dioxide (CO2) is a hot topic. Scientists around the globe are searching for ways to store, dispose of, or prevent the formation of the greenhouse gas, which is a major driver of global climate change. Liquid Light hopes to take this concept one step further and harness waste CO2 as a source of carbon to make industrial chemicals and fuels.
  • Take CO2 and mix it in a water-filled chamber with an electrode and a catalyst. The ensuing chemical reaction converts CO2 into a new molecule, methanol, which can be used as a fuel, an industrial solvent or a starting material for the manufacture of other chemicals.
  • Bocarsly likes to call the process "reverse combustion" because it is like running a burning reaction backwards. Instead of burning fuel and oxygen to produce CO2, the CO2 converts back into fuel and oxygen.

  • Cole set up a flask containing a solution of CO2 and a pyridinium catalyst dissolved in water. In place of sunlight, which emits a broad spectrum of wavelengths of light, she shined on the flask a blue light-emitting diode (LED) because it gives off certain wavelengths that are highly efficient at driving the reaction. In the flask she placed an electrode that is activated by particles of light, or photons. "We used a semiconductor electrode that would allow us to substitute light for electricity," said Cole.
  • The Princeton scientists did some additional studies, and made a surprising discovery: They could turn CO2, which contains only one carbon, into a compound with a carbon-carbon bond, which vastly increases the possibilities for creating commercial applications.
