"There are a lot of dangerous stereotypes out there. "Asian students are always better at math." "Boys are always better at sports." And perhaps the most dangerous of all: "The current generation are all digital natives." It is easy to see the danger in the first two stereotypes. They tend to influence the way teachers, parents, peers and society in general classify, justify and treat whichever group is represented by the stereotype. I'm not sure enough people give enough thought to the third, equally dangerous, stereotype."

"Pokemon GO, an augmented reality (AR) mobile game that requires players to venture out into the real world to play, has courted many catastrophes. In search of rare Pokemon, players have stumbled into dangerous neighborhoods, fallen off ocean bluffs, and been robbed; all because they were completely immersed in the game. If not used carefully, Pokemon GO can be dangerous."

"I read Fareed Zakaria's work often. He's a great journalist for the Washington Post and a TV news anchor with his own show on CNN. I dug into a piece yesterday he wrote titled "Why America's Obsession with STEM Education is Dangerous". Unlike Zakaria's articles on foreign policy, which are insightful, thought-provoking, and in-depth, this article paints an innacurate and overly-simplified picture of what STEM education is and should be. Worse yet, his argument injects dangerously reductive rhetoric into the public debate on education, where we already see heightened emotion and political division. Maybe this type of reaction is what Zakaria is aiming for. He releases a new book today on this same topic called "In Defense of a Liberal Education". "

"No mess.  No danger.  No smelly fumes. BBC Brit's Biggest Bangs is a fun, interactive video experience that allows users to channel their inner mad scientists, mixing dangerous chemicals with sometimes explosive results without a proper laboratory. The secret behind the interactivity is a central choose-your-own-adventure video around which annotations lead to separate videos that respond to your chemical selections. Choose your first chemical and then select another from among eight on the laboratory table.  You'll see the team scientist take each chemical from the table.  Then pause to consider-will it explode or won't it?"

Teaching is by nature a high energy profession that demands a lot and while their is much to celebrate there is arena danger of burnout. Taking some time to relax and de-stress is important as is noticing the signs that you are reaching your limit. For all teachers understanding that a break and a change of schedule benefits not just you but your students too can be the catalyst for granting yourself permission for a genuine break.

"Software engineer Ken Shirriff took a close look at 12 different USB power adapters and confirmed what we already suspected -- that counterfeit chargers are junk. They are poorly constructed and can cause serious damage to both your devices and yourself."

Phones and computers contain dangerous metals like lead, cadmium and mercury, which can contaminate the air and water when those products are dumped. It's called electronic waste, or e-waste, and the world produces a lot of it: 20 to 50 million tons a year, according to the UN - enough to load a train that would stretch around the world. The U.S. is by far the world's top producer of e-waste, but much of it ends up elsewhere - specifically, in developing nations like China, India and Nigeria, to which rich countries have been shipping garbage for years.

"As web companies strive to tailor their services (including news and search results) to our personal tastes, there's a dangerous unintended consequence: We get trapped in a "filter bubble" and don't get exposed to information that could challenge or broaden our worldview. Eli Pariser argues powerfully that this will ultimately prove to be bad for us and bad for democracy. Description from TED Talk site."

I want my students to be sceptics. I believe that in the present age scepticism is more important than ever. Easy access to information, ease of publishing, scams and confidence tricksters combine to create a climate where blind trust is dangerous for our security, our finances and our knowledge bases. For students of all ages a healthy dose of scepticism is much needed not just so they may reveal falsehoods but to allow them to discover new truths.

The maker movement and with it maker-centered learning brings new possibilities and challenges into the classroom. It has spawned makerspaces and students are busy designing and making products. The danger with all this frenzied making is that it is very easy to miss the point, to focus on the product and not the journey.  

"As you've no doubt noticed, Pokémon GO has taken the world by storm since its release on July 5, 2016. It's getting people outside to actively explore their surroundings and giving millions their first experience with augmented reality. But it's also raising questions and concerns about whether the game's location and mapping features are compromising people's data and information and luring players into danger. With school starting up again soon, we wanted to offer some guidance for teachers on how to address and manage the Pokémon GO craze in your classroom and school. "

"here is a lot of potential in the 'maths apps' available in the App Store, although most of the 'maths apps' appear to be drill practising of number facts and operations. Whilst, there's no problem in children using these apps in the classroom to develop their maths skills, there is a danger that the iPad becomes no better than a laptop or a desktop computer for the learning of number facts and rote learning. For the iPad to reach its full potential the challenge is to make maths real in the classroom and engaging for the children. "

"A few weeks ago, I introduced some of our 2nd grade elementary students to some iPad apps that let you work in 3D! Sometimes it is difficult to do 3D art projects in the art room because you need so much room to store projects from week to week. Working on the iPad lets students have some interesting virtual art experiences without the need for storage, mess, and in some cases dangerous tools."

"Nowadays, kids want to use smartphones. Of course, most parents aren't willing to actually buy their kids a device, but plenty have no problem letting them play with one. Of course, when a child uses a cell phone they can potentially be exposed to all kinds of dangerous things that aren't meant for young eyes. But the risks aren't just for the children, but they can affect you, the parents, too. Kids could make unwanted in-app purchases, make calls to people you don't want to talk to, they could even share photos you don't want the world to see, and they can do plenty of other bad things. So what can you do? Check out the infographic below for the answers."
