Comment: I don't think that the audience for this is kids.. (Score 1) 384

I think that it is more parents, school administrators, and teachers. Just today a fellow teacher who had her 5th graders using Scratch to program solutions to math problems as a programming exercise was visited by our principal. The principal walked around and observed, asking the kids questions like "How will this help you in the future?" because that is apparently one way to assess teachers now. She had no clue what the kids were doing, or how it may help them understand math, logic, problem solving, or that they may find they have a talent, like, or even passion for it. We sent her a link to code.org with the hope that Gates and Zuckerburg endorsing something not in our standard curriculum may hold more weight than two rebellious teachers.

If coding is going to be more than a small elective in some middle and high schools, politicians and the educational bureaucracy need to believe that there is some value in it. They are the target.

Here's some data from Florida to back up your point. You have to conclude that either a) most teachers who teach in lower-socioeconomic schools are bad, or b) standardized tests assess student socioeconomic status better than teacher quality. I've worked in several Title 1 schools and from my experiences, teachers there work hard, put in more time, and work smarter than teachers at upper socioeconomic schools just because they have to.

I know that the politicians and testing and charter companies have done everything they can over the last few decades to convince you otherwise, but nothing pisses most teachers off more than when one of their students isn't learning and we do everything possible to help them.

Space

+ - Asteroid the 'Size of a Minivan' Exploded over California->

astroengine writes "The source of loud "booms" accompanied by a bright object traveling through the skies of Nevada and California on Sunday morning has been confirmed: it was a meteor. A big one. It is thought to have been a small asteroid that slammed into the atmosphere at a speed of 15 kilometers per second (33,500 mph), turning into a fireball, delivering an energy of 3.8 kilotons of TNT as it broke up over California's Sierra Nevada mountains. Bill Cooke, head of NASA's Meteoroid Environment Office, classified it as a "big event." "I am not saying there was a 3.8 kiloton explosion on the ground in California," Cooke told Spaceweather.com. "I am saying that the meteor possessed this amount of energy before it broke apart in the atmosphere. (The map) shows the location of the atmospheric breakup, not impact with the ground." Interestingly, this event was bigger than asteroid 2008 TC3 that exploded over the skies of Sudan in 2008 after being detected before it hit."

+ - Strange cloud formations on Mars, a mystery-> 1

techfun89 writes "Mars has returned to our evening skies as it does every two years. This time it is getting even more attention and buzz than it normally would. Amateur astronomer Wayne Jaeschke of West Chester Pennsylvania noticed an unusual protrusion in the planet's southern hemisphere, preceding the sunrise terminator.

Several things may have contributed to this strange "cloud formation". One possibility is a meteoric impact event, where dust was spewed up into the atmosphere. Another could be a major dust storm, which are typical on Mars. While the other possibility is the more mundane, that these observations were caused by a mere optical illusion via a type of glint that occurred due to having just the right combination of lighting and atmospheric conditions. Some suggest volcanic activity, though this is unlikely given it has been 20 to 200 million years since lava has flowed on Mars."

Education

+ - Learners earn Open Badges from Mozilla ->

Submitted by mikejuk
mikejuk writes "Mozilla better known for open source projects such as Firefox and Thunderbird has gone into the education market — sort of. It has announced "Open Badge" an API for earning and displaying badges that indicate just what you have learned. Think of it as earning merit badges but without having to join the scouts... More seriously badges allow micro rewards for small achievements which could motivate the learner to do even more. This could be the future of educational accreditation — no more Degrees, Masters or PhDs just a backpack of badges."

I'm an elementary school teacher, and we have 2nd graders using Scratch at my school with great success. Having them create interactive multimedia may be a better way for you to start - create some characters, program them to do or say things in sequence and interact when they touch each other. Be sure to check out the in-program help section and print out the "Scratch Cards" as an easy way to get kids started. Also, check out http://scratched.media.mit.edu/ for lesson plans and ideas from teachers around the world.

Another idea - I just downloaded and started reading some documents on "CT" - Computational Thinking from ISTE and CSTA ( http://www.iste.org/learn/computational-thinking.aspx - free registration required to download). Haven't read it all or used it with kids yet, but it looks interesting. There are suggested activities that don't involve computers, similar to a few mentioned in previous posts to get kids to think about processes, algorithms, etc... including stuff for younger kids.

The announcement triggered over 27,000 comments on the Netflix Facebook page. I could not find a positive comment in this stream of anger and announcements of service cancellations. So what did Netflix do?"

I'm not a grad student at the Media Lab, and I'll second everything the poster above said. I've been using Scratch with 5th grade students for physics and even some simple ecosystem simulations (all student created) for about 4 years now. The programming language is simple enough to get out of the kids' way and let them create what they want. Whatever you are teaching - if the kids truly understand it they can show you by creating a sim for it, and if they don't understand it they have to figure it out in the process.

Space

+ - MESSENGER In Orbit Around Mercury->

Submitted by krswan
krswan writes "From the NASA press release: "At 9:10 p.m. EDT, engineers in the MESSENGER Mission Operations Center at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., received the anticipated radiometric signals confirming nominal burn shutdown and successful insertion of the MESSENGER probe into orbit around the planet Mercury."

If you don't know much about this little spacecraft, check out its website. Designed with a completely passive cooling system, it will stay at 600C on the sun side, but room temperature behind the sunshade. During its 6 year journey it used its solar panels as sails, using the solar wind instead of thrusters to adjust its trajectory. Over then next year it will build a high-rez map of Mercury, and maybe determine if there is really ice hiding in polar craters on Mercury."

I have a friend who just flew to India for a month to clean up an outsourcing mess for his company. Months behind schedule, 1/2 million over budget... from what he told me folks there had been promoted way above their ability level resulting in really substandard management and unsurprising results.
