Community College Consortium for Open Educational Resources The Educator's PLN Diane Ravitch (DianeRavitch) Where is M13? - Home Where is M13? — A Three Dimensional Galactic Atlas! We all have our favorite deep sky objects that we've looked at hundreds and hundreds of times. We know where to find them in the night sky, but most of us have little idea where they lie in the three-dimensional space around our Galaxy. Isn't that just a bit strange? Where is M13? At home, Where is M13? Using paired face-on and edge-on views, the Galaxy View shows you where that cluster or nebula is actually located relative to the center and plane of the Galaxy, providing a unique 3-D perspective. Below the paired views, the Object List provides important physical information about the objects. The Sky View shows you where the objects are found in the night sky, using a star map plotted in galactic coordinates. Where is M13? Where is M13?

If we didn't have the schools we have today, would we create the schools we have today? Contemporary Issues in Technology and Teacher Education [Online serial], 1 (1). If We Didn’t Have the Schools We Have Today, Would We Create the Schools We Have Today? Thomas G. We have a unique opportunity in education today. The investment of resources on this scale is comparable to the space program. When the Wright brothers were going to make the first flight, there was no flight school to prepare them. “If We Didn’t Have Today’s Schools, Would We Create Today’s Schools?” The question in the title of this article is a trick question, because I want readers to really think about it. If a surgeon from the 1800s walked into an operating room today where arthroscopic surgery was being performed, could that surgeon step in and perform the surgery? Can Technology Be Used to Improve Education?
Diane Ravitch's blog Electromagnetic Spectrum - Introduction The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays. You know more about the electromagnetic spectrum than you may think. The image below shows where you might encounter each portion of the EM spectrum in your day-to-day life. The electromagnetic spectrum from lowest energy/longest wavelength (at the top) to highest energy/shortest wavelength (at the bottom). Radio: Your radio captures radio waves emitted by radio stations, bringing your favorite tunes. Microwave: Microwave radiation will cook your popcorn in just a few minutes, but is also used by astronomers to learn about the structure of nearby galaxies.

Home Sir Ken Robinson: Transform Education? Yes, We Must As the new members of 111th Congress wander through the building looking for their desks and lockers, it may feel for some of them like the first day at school. They should hold on to that feeling. One of the biggest challenges they face is sorting out American education. Given the recession, the dire situation in the Middle East and the general state of the planet, education is probably not at the top of their to-do list. It must be soon. President-elect Obama swayed the nation on a promise of change and the renewal of the American Dream. All of this is the work of education. My family and I moved to America almost eight years ago. President-elect Obama has said that NCLB was well intentioned, and it was. I said that the premise of the act is flawed. To face the future, America needs to celebrate and develop the diverse talents of all of its people -- young and old alike. I'm always struck by how many adults have no idea what their real talents are, or whether they have any at all.

Stephen Downes: Fairness and Equity in Education The Idea of Fairness If we were asking questions of the children in a classroom, we wouldn't ask just one person over and over, right? We would want to spread the questioning around. Or if we were running a class debate, we wouldn't let just one student speak for the entire session, right? We would want to ensure that a number of different voices were heard. We wouldn't design our tests so that only one person could pass. There is growing recognition that there might be something to this principle. The United States came out only in the middle of the PISA rankings. As the PISA authors noted, poverty itself wasn't the problem. All of that said, while it is all very well to appeal to some sort of principle of fairness, the fact remains that there is no widely accepted economy of fairness. Efforts to ground the principle in moral or philosophical arguments are equally futile. The Golden Rule allows the powerful to legitimize their power, and does not promote fairness at all.
