Social media's ascent has led to an Internet experience based less on pages and more on people. As a corollary to this (and counter to Marshall McLuhan's thesis), the medium is no longer just the message. The permanence of words and images and their meaning in context has long been promoted as a foundation of media theory. In an increasingly real-time environment, however, content gives way to identity, and traditional contextual analysis gives way to dynamic social interactions.

"For nearly 30 years, personal computers as we have known them have been the drivers of the technology engine. From Intel to Microsoft to Dell to HP to Micron Technology - many fortunes were made on the back of the PC. But the rise of mobile computing is upending the technology business and is simultaneously redefining what is a personal computer and how we use it. On Thursday Hewlett-Packard, one of the oldest companies in Silicon Valley with deep connections to the PC ecosystem (they paid $25 billion for Compaq in 2002) and the world's largest seller of PCs, confirmed it is looking to sell off its personal computing business. "

Welcome to the butterfly wing pattern module of Class Insecta. Most butterfly and moth wings are covered with a dense mosaic of tiny individually colored scales forming a myriad of striking color patterns and designs. This beauty has elevated human perception of butterflies to a level of heightened appreciation. As you browse the six posters, you'll learn about wing structure, design analysis, pattern formation and adaptational benefits.

Several tools out there that can help analyze Twitter data, understand user behavior, and graph it for analysis and presenting to others.

The greatest challenge is moving beyond the glitz and pizzazz of the flashy technology to teach true literacy in this new milieu. Using the same skills used for centuries-analysis, synthesis, and evaluation-we must look at digital literacy as another realm within which to apply elements of critical thinking... Literacy includes the ability to read and interpret media (text, sound, images), to reproduce data and images through digital manipulation, and to evaluate and apply new knowledge gained from digital environments. According to Gilster,5 the most critical of these is the ability to make educated judgments about what we find online.

"It took just one relentless bout of the flu to remind me of the power of empirical evidence and the importance of shooting data. More than numbers, it was the evidence gleaned from my experiences and the images that I gathered along the way that helped my doctor solve the riddle that was delaying my recovery. My kids thought I was crazy, but I took some photos to save the evidence, and my doctor appreciated this. Gross? Absolutely. Helpful? Definitely! The doctor said that the pictures inspired him to take a different approach in my treatment. "Good data gathering," he joked, and I smiled, recalling one of my greatest pet peeves: educators and parents who rant about their disdain for this very important work. To listen to some, you'd think data are only numbers that shady reformers crunch in order to cash in on imaginary problems created by incompetent teachers. This is a dangerous assumption. The fact is that data are information that matter, and if they don't matter or if the conclusions we reach aren't helping us solve important problems, then we need to change the data we're collecting and the way we approach analysis. After all, isn't it a bit silly to blame data for our own faulty decision making?"

"Since this year's WWDC keynote ended, the focus of any analysis on iOS 8 has been its features - things like Continuity, Extensions, and iCloud Drive. This is, of course, expected: iOS is the operating system that drives Apple's most important (and most profitable) products, so it's natural that the limelight be shone on the new features for the mass market. As I've written, however, the Accessibility features that Apple includes in iOS are nonetheless just as important and innovative as the A-list features that Craig Federighi demoed on stage at Moscone. Indeed, Apple is to be lauded for their year-over-year commitment to improving iOS's Accessibility feature set, and they continue that trend with iOS 8. Here, I run down what's new in Accessibility in iOS 8, and explain briefly how each feature works."

"Consider these words from Peter Gray, author of "Free to Learn: Why Unleashing the Instinct to Play Will Make Our Children Happier, More Self-Reliant, and Better Students for Life:" Free play is nature's means of teaching children that they are not helpless. In play, away from adults, children really do have control and can practice asserting it. In free play, children learn to make their own decisions, solve their own problems, create and abide by rules, and get along with others as equals rather than as obedient or rebellious subordinates. Peter Gray's words remind me of danah boyd's descriptions and analysis of the over-scheduled lives of teens in her recent book, "It's Complicated: the social lives of networked teens.""

"How many times have you heard that "practice makes perfect?" Well, a new meta-analysis of dozens of previous studies shows that it is not always true. In this post, Alfie Kohn explains and talks about the consequences of this when it comes to education. Kohn is the author of 13 books about education and human behavior, including "The Schools Our Children Deserve," "The Homework Myth," and "The Myth of the Spoiled Child: Challenging the Conventional Wisdom About Children and Parenting." He lives (actually) in the Boston area and (virtually) at www.alfiekohn.org."

"Lately I've found myself squinting a bit at some of the practices and structures in teaching and learning. This squinting is less about efficiency or performance, but rather what effect each piece has-a kind of causal analysis. This is the cause, and it might have this effect. In trying to imagine what would be different if we did this instead of that, I was surprised at how education has settled one a small handful of models in light of so much possibility. Was it because we've found the magic formula, and in 2014 we're in an era of simple refinement? That we know "what works," and now it's all a matter of tweaks? That if teachers just listened and did what they were told and used #edtech and stuck to the script and if parents just read to kids and if poverty wasn't an issue and if classrooms were more inviting and we just used the data that is staring us in the face that it'd all somehow coalesce? So, this list. Other ideas for learning. I'm not saying any of these ideas are good-or even the least bit viable. I'm not saying they wouldn't be downright destructive, curiosity-snuffing intellectual abominations that'd take education back to the dark ages. I'm just wondering what would happen."

"A large review recently published in The Journal of the National Cancer Institute confirms what we've been hearing for years: Sitting can be fatal. + It's been linked to cancer, diabetes, and cardiovascular disease. In this latest meta-analysis, Daniela Schmid and Michael F. Leitzmann of the University of Regensburg in Germany analyzed 43 observational studies, amounting to more than 4 million people's answers to questions about their sitting behavior and cancer incidences. The researchers examined close to 70,000 cancer cases and found that sitting is associated with a 24% increased risk of colon cancer, a 32% increased risk of endometrial cancer, and a 21% increased risk of lung cancer. + The really bad news: You can't exercise away the habit's harmful effects. "Adjustment for physical activity did not affect the positive association between sedentary behavior and cancer," the authors write. Even participants who achieved the daily recommended levels of physical activity were at the same risk as those who spent their day sitting. "[The results] indicate that the increased risk of cancer seen in individuals with prolonged time spent sedentary is not explained by the mere absence of physical activity in those persons," the researchers say. + S"

Handing Assessment Over to Students I have been giving a lot of thought about how to give my students more of a voice in their learning and in our classroom. Initially, I was focused on increasing their presence on our classroom blog through podcasts, videos, and blog posts. I even gave thought to asking my district IT to unblock Twitter so that we could create a class account (which I am still going to do). But never would assessment have crossed my mind. Fortunately, I took my thoughts to my PLN. Janine Campbell (@campbellartsoup) responded to my tweet about amplifying students' voices with rich insights and a couple articles that got the cerebral wheels turning. If you like what you read here, be sure to follow Janine on Twitter. Assessment for learning is a pedagogical golden nugget. No one ever said that the teacher had to do it alone. Why not give your students a voice in how they are assessed? It might tell you more about where they are at than assessing your class conventionally. Rubrics are my favorite way to assess student projects. I'm even pretty good at creating them. By doing so, I completely understand the assignment and learning outcomes for any given project. But do my students? Is there a way to better utilize rubrics as assessment of learning where students' voices are intensified. Yes! Allowing students to create the criteria for assessment does just that. It doesn't just serve the purpose of better summative assessment. Student-created rubrics also provides a medium for formative assessment as well. If my assignment is for students to analyze the effects of the assassination of Abraham Lincoln on post-war America, I will be able to formatively assess the class' understanding of the main points of this event by the criteria that they suggest this assignment should be graded on. I will know that I need to reteach aspects of this event in American history if students believe that including a description of John Wilkes Booth's escape from Ford's The

There is something about human nature that draws us towards dichotomous patterns of thought; an all or nothing, us or them style of thinking in which an option is either good or it is bad. In such a model complexity and subtle nuance with multiple possible outcomes and routes towards a goal are ignored. The field of educational technology is one where such a pattern is evident and recent ban on technology by a Sydney school shows how this style of analysis can have a significant impact on student learning.

"Newark, Del. It's no secret that American workplaces are becoming more reliant on technology. But what may surprise the country's K-12 educators and policymakers is how work at nearly every rung of the employment ladder is becoming more digitized. Often, the skills needed to succeed have less to do with computer programming than what experts call "digital literacy"-the ability to interpret, create, and strategically use digital information. "Everyone's job is changing," said Mark Muro, a senior fellow and policy director at the Brookings Institution, a think tank. "The ability to read and then conduct first-order analysis of digital information is highly valued in almost all work environments." To better understand the central role of digital literacy in the workplace, Education Week took a deep look at four occupations in the Christiana Care Health System. It's the largest private employer in Delaware, with 11,600 employees and an expected 1,500 new hires this year."
