Effects on the brain of screen time on children

"For as long as I've been aware of makerspaces, I haven't quite understood them. I have seen plenty of photos on social media, with the towers made of marshmallows and toothpicks. I've walked through exhibit halls at conferences where the coding and robotics displays cause me to stop, stare, and try to look like I have some idea of what I'm looking at. I even stumbled into a Twitter chat one night where a group of school librarians was throwing around some pretty great ideas about building makerspaces in their libraries. And yet, I still feel like I don't get it. I have this picture in my mind of kids kind of messing around with Legos instead of, I don't know, reading primary source materials that would shed light on some period in history. Or taping together some cardboard strips to make them into a car. Or attaching some kind of wire to a banana. I don't know…the more traditional, stodgy, control-freak part of me says it looks like a bunch of hooey. But some of the smartest people I know are pretty into makerspaces, and the part of me that's not a stodgy control freak, the part that knows there's a lot about tradition we need to question, that part of me wants to find out once and for all what's so great about makerspaces."

"One question has fascinated me my entire adult life: what causes some people to become world-class leaders, performers, and changemakers, while most others plateau? I've explored the answer to this question by reading thousands of biographies, academic studies, and books across dozens of disciplines. Over time, I've noticed a deeper practice of top performers, one so counterintuitive that it's often overlooked. Despite having way more responsibility than anyone else, top performers in the business world often find time to step away from their urgent work, slow down, and invest in activities that have a long-term payoff in greater knowledge, creativity, and energy. As a result, they may achieve less in a day at first, but drastically more over the course of their lives."

"In the last decade, rates of anxiety-related disorders in teenagers have steadily risen, particularly in girls. Researchers and psychologists posit several hypotheses about why these rates are on the rise -- from digital hyperconnectivity to heightened external pressures to simply a greater awareness, and therefore diagnosis, of mental health concerns. Whatever the causes, Dr. Lisa Damour has hopeful news for parents and teens: first, some degree of stress and anxiety is not only normal but essential for human growth. And if those levels become untenable, there are tested strategies for reining anxiety back in."

"When I was a kid, my dad taught me how to make paper airplanes. I remember two designs in particular-a sleek 'jet' plane and a more-square stunt plane. I liked the stunt plane but was fascinated with the power and design of the jet version. It was so simple and pure. I can still remember the feel of the creases beneath my forefinger on my right hand, eyes studying my work closely, making sure the edges lined up just so. If it was off even a little, I had to start again. There's a lot more design that goes into duplicating n existing paper airplane model than you'd think. First and foremost, the aforementioned precision of the folds. If the paper isn't aligned perfectly, it won't fly perfectly-and that sort of linear cause/effect is strangely fulfilling."

"I hope you'll agree with me that we have a serious lack of female engineers, software developers, architects, and mathematicians. Women are painfully underrepresented in the industries and fields responsible for making the products we all use on a daily basis. Women are under-represented in creating the software that makes everything from fridges to turbines "smarter." Women are under-represented in engineering products including those that help us live healthier & safer lives. Women are under-represented in leading research and experimentation. The problem is significant & complex. Many governments & businesses including Apple & Google are actively working to root-cause why the results are so dramatic, and what business, governments and individuals can do to reverse the tide. "

I would like to propose that one cause of curriculum overcrowding is a phenomenon I refer to as "Idea Creep".

There are terms within education that we use with reckless abandon and as a result cause great levels of confusion. Understanding is one such word and its usage and our 'understanding' of it can have a significant effect on the learning we plan, deliver and assess. With multiple definitions and its broad usage in curriculum documents, philosophies of teaching and learning and as an indicator of the quality or depth of student learning it is a word we should better understand. 

"What are the kinds of ideas that convince people that they can change the world? What about students-what kinds of inspiration or knowledge or confidence or vision do they need to believe they can affect real change in their community? This is, at its heart, a matter of critical literacy-the kind of knowledge that empowers students to change their world. Social activism often appears in light of political leaning, but is first a matter of people gathering for a common cause in pursuit of change."

"I was listening to Chris Molanphy's excellent Hit Parade podcast this week, which is based on his equally great Hit Parade column for Slate Magazine. In this episode, he details the circumstances that lead the Beatles to hold the still-unbeaten record of having the top 5 spots on the Billboard charts all at once. More remarkably, it's not that this feat was achieved through their own talent - it was almost entirely a snafu caused by the lack of interest in the Beatles by major labels. Indeed, much of the feedback they had received from labels and the American music industry was tepid at best and negative at worst. Dick Rowe at Decca Records cemented his place in history by declining to sign the Beatles, saying "Guitar groups are on the way out." He wasn't wrong - the data he had showed that there wasn't likely to be much of a return in signing the Beatles. Instead, Decca signed Brian Poole and the Tremeloes, who would cost them less money. And so, you're probably wondering how in the world this connects to education. When I look at this moment in history, I see a lot of talented people making choices which are informed by data. As teachers, we too need to look at data. It's how we understand our students better, and when used properly, can be influential in shaping our practice to make our teaching more effective. Certainly data is used as a summative tool, but it is most useful as a formative tool for students and teachers alike. How does the use of data in regards to the Beatles relate to teachers?"

"As I wrap up my first month of consulting, I have one overarching takeaway: in every building, in every district, in every city, in every state, there are administrators, teachers, and students who are so passionate about learning that you can feel the positive energy in the room. It's humbling. It's heartwarming. It's inspiring. Yet, what I also see are lots of educators and students who frequently second guess themselves, continuously ask for permission to do anything, or who render themselves silent in large groups and appear to have "given up." However, behind closed doors, these are the same educators and students who are overflowing with enthusiasm and have a wealth of knowledge. Naturally, I have been doing a lot of thinking about the strikingly similar behaviors both adult educators and student learners demonstrate in our current educational system. What causes passionate learners to become apathetic toward their passion? Why do students and adults alike ask for permission to learn? And, I keep coming back to one simple conclusion. THE DEFICIT MODEL OF EDUCATION HAS WORN US ALL DOWN"

"Released in 2013, the NGSS was created to align science education with how scientists actually work and think. It encourages students to learn science content and concepts deeply by using critical thinking and primary investigation skills. Adopted by 18 states (with as many as 40 interested and in the process), the standards define science education through core concepts (such as wave properties), practices (like analyzing and interpreting data ) and crosscutting concepts (like cause-and-effect). Some of the NGSS guidelines directly overlap with the practices listed in the K-12 Computer Science framework and the new CSTA Computer Science standards. Here's a doodle that illustrates how the two subjects overlap. "

Constructivism is one of those ideas we throw around in educational circles without stopping to think about what we mean by it. They are the terms that have multiple meanings, are at once highly technical and common usage and are likely to cause debate and disagreements. Constructivism in particular carries a quantity of baggage with it. It is a term that is appropriated by supporters of educational approaches that are in stark contrast to the opposing view; constructivism vs didactic methods or direct instruction. The question is what are the origins of constructivism and does a belief in this as an approach to understanding learning necessitate an abandonment of direct instruction or is this a false dichotomy?

"As adults witness the rising tides of teenaged anxiety, it's tough not to notice a common thread that runs through the epidemic - something that past generations never dealt with. Clutched in the hand of nearly every teen is a smartphone, buzzing and beeping and blinking with social media notifications. Parents, all too often, just want to grab their teen's phone and stuff it in a drawer. But is social media and the omnipresence of digital interactions really the cause of all this anxiety? The short answer is: It's complicated."

"For much of the past half-century, children, adolescents and young adults in the U.S. have been saying they feel as though their lives are increasingly out of their control. At the same time, rates of anxiety and depression have risen steadily. What's the fix? Feeling in control of your own destiny. Let's call it "agency." "Agency may be the one most important factor in human happiness and well-being." So write William Stixrud and Ned Johnson in their new book, The Self-Driven Child: The Science and Sense of Giving Your Kids More Control Over Their Lives. Feeling out of control can cause debilitating stress and destroy self-motivation. Building agency begins with parents, because it has to be cultivated and nurtured in childhood, write Stixrud and Johnson. But many parents find that difficult, since giving kids more control requires parents to give up some of their own."

As schools and organisations move to remote education, there are potential gaps in our professional learning of which we should be aware. While many of us are discovering fresh opportunities for online and remote professional learning through podcasts, webinars and online courses, one of the most significant aspects of our professional learning has been curtailed thanks to social distancing.

"Why do teenagers seem so much more impulsive, so much less self-aware than grown-ups? Cognitive neuroscientist Sarah-Jayne Blakemore compares the prefrontal cortex in adolescents to that of adults, to show us how typically "teenage" behavior is caused by the growing and developing brain."
