12/21/12: Definitely Not the End of the World | Wired Science | Wired.com - 29 views

  • There is not a single iota of evidence that large-scale planetary alignments cause changes in geologic events – like earthquakes and eruptions – on Earth. The only celestial bodies that could play some role – and there is some evidence that suggest that they may, in minor ways – are the Sun and the Moon. This is due to their relative close proximity (especially the moon) and their mass. I’ve covered some of this in my discussion of why the so-called “Supermoons” are silly and play no role in increasing/decreasing geologic events. What about the alignment with the galactic center? The center of the galaxy must exert some force on the Earth (and solar system) or we wouldn’t be orbiting it. However, beyond that fact that alignments like this happen all the time, the force that the galactic center exerts on Earth is ~0.00006x that of the Moon on Earth and ~0.00000037x that of the Sun, doesn’t it seem a little ridiculous to claim that the galactic center can change anything on Earth if the Sun and the Moon cause little-to-no effect on geologic events?

Teach with Picture Books: You Say You Want a Revolution? - 78 views

  • The American Revolution gave birth to a new country, but now, more than 200 years later, so many stories of this incredible time in history are yet untold. Most of us know about Paul Revere, George Washington, Thomas Jefferson, and perhaps even Molly Pitcher, but what of the smaller, yet equally important roles played by American Patriots?

Getting Into the Ivies - NYTimes.com - 0 views

  • For American teenagers, it really is harder to get into Harvard — or Yale, Stanford, Brown, Boston College or many other elite colleges — than it was when today’s 40-year-olds or 50-year-olds were applying. The number of spots filled by American students at Harvard, after adjusting for the size of the teenage population nationwide, has dropped 27 percent since 1994.
  • The share for any individual college is minuscule, of course. In 2012, about 33 out of every 100,000 American 18- to 21-year-olds were attending Harvard, down from 45 per 100,000 in 1994. These changes in the share tell you how much harder, or easier, admission has become for American teenagers on average. Between 1984 and 1994, it became easier at many colleges. The college-age population in this country fell during that time to 14.1 million in 1994 from 16.5 million in 1984, and the number of foreign students was relatively stable.
  • Over the last 20 years, several large colleges, like N.Y.U. and the University of Southern California, have improved markedly, effectively increasing the number of seats on elite campuses
  • ...3 more annotations...
  • For students from the Northeast applying to elite colleges in the region, college admissions have probably become even more difficult in recent decades than these statistics suggest. Not only have colleges globalized, they have also become less regional, admitting more students from states like North Carolina, Texas and Washington.
  • On average, about 15 percent of students at elite colleges receive Pell grants, which as a rule of thumb go to students in the bottom half of the income distribution.
  • Low-income applicants are left to compete for the remaining slots with applicants who have the highest test scores, most impressive extracurricular activities and most eloquent essays.

PowerPoint in higher education is ruining teaching. - 6 views

  • PowerPointless Digital slideshows are the scourge of higher education.
  •  
    A visual example of why teachers, whether in K-12 OR higher education might want to re-think their own use of PowerPoint slide shows. What she does not say, but probably should, is that any slide show should probably have only about 25% of the material that will be presented.

What makes an interactive whiteboard interactive? - Doug Johnson's Blue Skunk... - 25 views

  • But many advocates of this technology (myself included), see IWBs as genuine means of bringing more interactivity, more student-focus into classrooms of traditional teachers
  • What we don't want to forget is that someone who is coaching a teacher is not really looking for "good technology use" but for just good educational practices. Having an IWB is not going to change a lecturer into something else.
  • Any item in the Instruction domain can be enhanced using an IWB.
  • ...3 more annotations...
  • just because a teacher has an IWB doesn't mean it has to be used every minute of the day. And yes, a teacher can create truly interactive lessons without using any technology whatsoever.
  • use the SmartNotebook software that works with the hardware to organize materials, to find and share lessons, and to seamlessly blend multimedia into lessons.
  • While popular (2007, 2010, interactive white boards (IWBs) are controversial even (or especially) among technology enthusiasts. The major complaint is that the use of these devices reinforces the "sage on the stage" teaching methodology. "The IWB is little more than a fancy overhead projector and its touch sensitive screen is only used to save the teacher a couple steps back to the computer to change a slide."
  •  
    Blog post that articulates some of the best practices for incorporating an interactive white board (IWB), like a SMART Board, into your classroom in meaningful and instructionally sound ways.

Thinking about solar? It's easier to start small | Green Tech - CNET News - 12 views

  • Thinking about solar?
  • Green Ray Solar this week is expected to announce UL certification for a solar panel that puts out alternating current, rather than direct current as most solar photovoltaic panels do today. AC panels can be simpler to install and wire together than traditional panels, which makes a piecemeal approach easier,
  • Traditionally, solar panels are tied into a device called an inverter, which converts the direct current from panels into household alternating current. Strung together, several panels produce enough voltage to run an inverter which, sized for a rooftop array, is roughly as big as a computer monitor.
  • ...2 more annotations...
  • A microinverter brings that DC-to-AC function onto each individual panel. Proponents say the technology simplifies installation and improves panel performance.
  • For example, shading on one panel will not affect the output of other panels connected to it, as happens with panels connected to a centralized inverter.
