"The history classroom was a mess. There were wires, nails, brads, and wooden pieces on every desk, and students around me struggled with a difficult task. I knew that, in the middle of the mess, I had reached a good balance between student independence and teacher instruction, between hands-on experience and historical material, when one of my students looked up and said, "Mrs. Pang, this is fun! It's really hard, but it's fun." She looked back down at the length of wire in her hands and kept winding it onto a large nail. She was following instructions to create the electromagnet on a telegraph machine. This student and her partner got theirs to work on the second try. Through this small making project, they were exploring the history of innovation and communication. At the same time, they were learning about making electrical connections, how to use tools, and how to troubleshoot their work when it failed. And they said it was fun. In my mind, they were referring to Seymour Papert's kind of fun: hard fun."

"The tiny and ridiculously inexpensive Raspberry Pi Zero has already proven to be a huge hit, selling out everywhere (including on the front cover of 10,000 magazines). But if you're one of the lucky 20,000 or so who managed to get hold of one of the £4 computers, you might be asking a deceptively simple question -- what next? The Zero is a surprisingly powerful machine, with 512MB of RAM and a CPU faster than the original Pi, but what do you need to get started and what projects can you tackle from day one? The following intro guide will help you go beyond simply staring at the miniature, refined brilliance of the Zero hardware, and actually start using it to make things, play games and experiment."

"THE WHOLE WORLD is exhausted. And it's killing us. But particularly me. As I write this, I'm at TED 2019 in Vancouver, which is a weeklong marathon of talks and workshops and coffee meetings and experiences and demos and late-night trivia contests and networking, networking, networking. Meanwhile, I'm sick as a dog with a virus I caught from my 3-year-old, I'm on deadline for what feels like a bazillion stories, and I'm pregnant, which means I need coffee but can't have too much, and need sleep but can only lay on my left side, and can't breathe without sitting propped up with a pillow anyway, since I can't safely take any cold medication. According to neuroscientist Matthew Walker, I'm doing serious damage to my health-and life-by not sleeping enough."

"School Design May Affect a Child's Grades"

"At GeekDad we are big fans of apps that actually use mobile devices in innovative ways to support children's learning. Motion Math Games are one of those developers who have led the way in thinking about how they can design digital learning environments that provide ways for children to learn math with their hands and minds. Their first fraction/decimals app called Motion Math has become one of the benchmarks against which others should be comparing themselves."
