"Those of you who live and teach in northern climes know what winter is all about. It's not about the beauty of the fluffy white stuff or the bone-chilling temperatures or even the short sunlight hours each day. In a primary classroom, it is really all about the snow clothes. Assuming that the temperature is warm enough to actually go outside (in my school division the children go outside unless the temperature-including wind chill-is below -28C), the whole putting on/taking off all those snow clothes takes up a LOT of time. For some students, it is a ten-minute process. And when you consider that it has to be done first thing in the morning, before and after two recesses, at lunch time and again at the end of the day…well, you can see a lot of time needs to go into this every day."

"You don't need a meteorologist to tell you what lake-effect snow is: it's snow that's, um, caused by a lake, right? As it turns out, things are a teensy bit more complicated than that, and if you live in one of the states bordering the Great Lakes that are forever getting clobbered by the stuff - or even if you just marvel at the footage of the latest white-out to hit those luckless places - it can help to know what's actually going on."

""How was skiing?" I asked my 14-year old daughter as she hauled her boot bag into the car. "Well, the ratio of snow to ground was definitely low," she replied, adding that she had tried to figure the ratio of snow-to-ground during practice but had received only mystified looks. "Stop the math!" demanded a coach. "You are confusing us!" Why do smart people enjoy saying that they are bad at math? Few people would consider proudly announcing that they are bad at writing or reading. Our country's communal math hatred may seem rather innocuous, but a more critical factor is at stake: we are passing on from generation to generation the phobia for mathematics and with that are priming our children for mathematical anxiety. As a result, too many of us have lost the ability to examine a real-world problem, translate it into numbers, solve the problem and interpret the solution."

"Most of the time when I take my dogs out at night I have to put on a headlamp (they have their own to wear too) so that I can see them in the dark. But this week the combination of a full moon and a fresh blanket of snow canceled the need for the headlamps. In the following Minute Physics video we learn why the full moon appears brighter in the winter. Hint, it's not the snow cover that makes the big difference."

"On the morning of Wednesday, February 22, 2017, my cell phone rang at 5:30 a.m. The caller ID told me that the call was from our school district. Even before I swiped to answer, the pop-up notification on my phone told me the nature of the call. School had been canceled for the day. That's not such an odd occurrence in February in southwest Missouri. Snow and ice have canceled school as late in the year as early May. However, we'd been enjoying a stretch of record high temperatures, and while I wasn't really awake enough for my rational mind to rule that out, I knew something was off. There has been a lot of construction to and around a few of the school buildings in our district. In December 2016, I happened to be privy to a conversation regarding low water pressure at one of the schools due to a water main issue at a construction site near that particular school. So, non-functioning utilities was certainly a possibility for canceling school that zipped through my not-yet-awake mind. I was not prepared for what the recorded voice of our district superintendent told me. School had been canceled because of the threat of violence."

"As Apple famously did with Snow Leopard on the Mac, this year's version of iOS primarily focuses on better stability and more polish. While there may be fewer "big" features in iOS 9, that doesn't mean that there are zero new things. If you're anything like me and Federico Viticci, champions of iPad productivity, then the tablet's new multitasking capability is headlining in itself. And, as I recently wrote for TechCrunch, Apple continues to push forward in its support for the accessibility community."

"NJIT Continuing Professional Education announces ONLINE iPhone/iPad Software Application Development training class. NJIT is one of the first universities to offer training about iPhone and then about iPad app development. This non-credit iPhone & iPad Application Development course adultlearner.njit.edu/admissions/prospective/iphone_online.php is open to the general public and is available 100% online. Participants in this class receive a login to the NJIT Apple Developer Program portal and receive full access to all of the NJIT Apple resources without paying the additional $99 Apple Developer Registration fee required of private developers. The Apple resources include documentation, development software and video tutorials. This portal now supports both the Mac OS X Lion and Snow Leopard Development environments."

"Today the buses were not running due to the early morning snow. As such we had about 40% in attendance between our four intermediate classes so we decided to conduct an impromptu maker fair. Here are some of our inventions. If you have any questions, please ask!"

"Here in New York, we still haven't gotten any snow. But don't worry-these are the snowflakes you're looking for. If you have 20 minutes, a working printer, an X-acto knife, and scissors, you can make these snowflakes inspired by the latest Star Wars flick."

"Kids can learn the physics of hockey and aerial skiing, the engineering of the halfpipe and bobsled, the chemistry of snow and ice, and the math of Olympic greatness -- all from fabulous five minute videos featuring winter Olympics. Not only that, but kids can apply these STEM concepts into improving their own winter sports abilities and use the knowledge to experiment with science, engineering and math through play. NBC Learn and the National Science Foundation have released Science of the Olympic Winter Games 2010 and Science and engineering of the Olympic Winter Games 2014 to teach the science and engineering behind individual Olympic events. There are sixteen videos in the 2010 series and ten videos in the 2014 series. Each video is approximately 5 minutes long, and the 2014 series includes lesson plans, integration guides and ideas for hands-on investigations, as well."

"WWF Together is a beautiful iPad app and Android app that features interactive stories about endangered animals around the world. Each of the interactive stories includes beautiful images and videos, facts about the animals and their habitats, and the threats to each of the animals. Some of the animals currently featured in the app are pandas, marine turtles, elephants, tigers, polar bears, bison, whales, gorillas, rhinos, and snow leopards."

"Halloween is packed away, Christmas looms on the horizon, report cards are consuming way too much time…all of which means it is almost one of my favourite weeks of the year: Hour of Code week! This year Hour of Code officially runs from December 4th to 10th. Last year our teachers and administrators worked really hard to ensure that students in all grades and across all of our schools got a chance to try one or two coding activities during Hour of Code week. I hope we do even better this year and for the next several weeks my blog posts will be dedicated to helping teachers prepare for Hour of Code in their classroom. However, in any discussion about coding, I think it is important to start off by discussing Computational Thinking. Computational Thinking is the basis for all coding. More importantly, it provides a great base for problem solving in any arena of life, from getting dressed for the snow to building a gingerbread house to completing a school project."

"What Teachers Wish They Could Say To Parents"

Most schools were built upon the idea that knowledge and teachers are scarce. When you have limited access to information and you want to deliver what you do have to every citizen in an age with little communication technology, you build what schools are today: age-grouped, discipline-separated classrooms run by an expert adult who can manage the successful completion of the curriculum by a hundred or so students at a time. We mete out that knowledge in discrete parts, carefully monitoring students progress through one-size-fits all assessments, deeming them "educated" when they have proven their mastery at, more often than not, getting the right answer and, to a lesser degree, displaying certain skills that show a "literacy" in reading and writing. Most of us know these systems intimately, and for 120 years or so, they've pretty much delivered what we've asked them to.
