About the Lecture Don't expect to glean any market tips or trading secrets from James Simons, who steadfastly refuses to disclose the method behind his remarkable record in investing. Instead, listen to this mathematician, hedge fund manager and philanthropist sum up a remarkably varied and rich career, and offer some "guiding principles" distilled along the way.

"On one particular day, I began to question my rationale behind all of this print media I was accumulating. Media that - in a matter of days - would get tossed in the recycling bin. "Why," I asked myself, "was I reading all of this print media when I have an iPad? Isn't print media supposed to be on its deathbed? Why was I sticking with a format that will soon depart this life?" Adding fuel to this query, I have more than two dozen news-related apps on my iPad - from the New York Times to Flipboard. Some of them are spectacularly well-designed. Yet, I was rarely using them. Why?"

What's the math formula behind this?

Teresa Penedo posted this item in the #change11 Facebook group. The one-hour video tells us "most of what we think we know about technology in general is false." According to Andrew Feenberg, "Our error stems from the everyday conception of things as separate from each other and from us. In reality they belong to an interconnected network the nodes of which cannot exist independently qua technologies." This leads to ten 'paradoxes of technology': "1. The paradox of the parts and the whole: The apparent origin of complex wholes lies in their parts but in reality the parts find their origin in the whole to which they belong. 2. The paradox of the obvious: What is most obvious is most hidden. 3. The paradox of the origin: behind everything rational there lies a forgotten history. 4. The paradox of the frame: Efficiency does not explain success, success explains efficiency. 5. The paradox of action: In acting we become the object of action. 6. The paradox of the means: The means are the end. 7. The paradox of complexity: Simplification complicates. 8. The paradox of value and fact: Values are the facts of the future. 9. The democratic paradox: The public is constituted by the technologies that bind it together but in turn it transforms the technologies that constitute it. 10. The paradox of conquest: The victor belongs to the spoils." from Stephen Downes OL Daily

"In the 2008 animated film WALL-E, Pixar depicted a light-hearted but dystopian world of obese, immobile people whose needs are met by a bustling horde of robots and computers -- a world that hardly seems like science fiction as we witness the precipitous decline in physical activity over the last generation. The Centers for Disease Control and Prevention estimates that approximately 80 percent of Americans don't get the recommended amount of exercise they need each week for optimal health. So, did Pixar predict the future of humanity or is there a way for us to course correct? Sedentary behavior is an intractable issue. Seemingly benign forces make it easier and easier for many of us to conduct our work, school and social lives from the comfort of a chair and an internet-connected gadget. Unfortunately, sedentary lifestyles are a driving force behind burgeoning health care costs, and they pose an alarming threat to the health and well-being of our children. Fortunately, there is cause for hope in lessons from the tobacco control movement and efforts to change smoking behavior. "

"Here is a chart I have been working on for the last couple of days. The purpose behind this work is tp provide teachers with a handy resource where they can have free and quick access to some of the best iPad apps to use in their teaching. As you can see below I arranged the apps in such a way that they cover several categories. From apps to creating presentations to apps for grading and creating portfolios, the chart below will assist you take your iPad experience to the next level."

"As I mentioned in my article, "The Research Behind 20% Time", there is a lot of support for this type of inquiry-based learning in schools. However, I want to point out a few important pieces of information in this post on why many of the folks talking about the demise of Google's 20% time and whether or not Genius Hour is enough…are simply missing the point."

"I was thinking about how I didn't use social media for such a long time and I was trying to figure out the "why" behind it."

"It's no secret that state and national assessments continue to indicate that boys lag behind girls in the area of reading. The gap tends to grow larger as students enter adolescence. It's also no secret that many teenage boys dislike reading - in class or at home. Just ask a high school teacher…or a teenage boy. While it's not true that all teenage boys dislike reading, there is a growing trend of many becoming unmotivated readers. Obviously, students who are resistant to reading are unlikely to get better at it. Here are four ideas for motivating adolescent male readers."

"Imagine you could create a single button on your iPhone that does whatever you want. Want to order an Uber for your next Calendar event? Easy. Want a button designated for calling mom? Done. Wish you could tap a button and get directions to the nearest coffee shop? Who wouldn't? Want to tweet the last photo you took or song you're listening to? Just drag and drop each step of the process inside of Workflow and it turns into its own app. That's the concept behind Workflow, a new app designed to save you time by allowing you to string together various tasks and combine them into one action. You can then turn that action into an app on your homescreen or add it to your iPhone's share screen so you always have quick access."

"As the beginning of another school year approaches, students face the dreading reality of putting the sunny, less-stress summer days behind and preparing for the next 10 months of deadlines, papers, homework assignments, tests, grades and teachers that seem to not understand what it's like to be a student in 2014. While some students anticipate the teacher that gives less homework, is humorous, easy-going and fair, other students cross their fingers in hopes of the teacher that will understand and accept them for being quiet."

"I have always believed that teachers (and people in general) MUST have an open midset; one that tolerates and celebrates mistakes and errors; one that looks at failure as an opportunity for a better beginning. It is through falling down that we stand up robust and it is through misfortunes that we gather our strength to live the life we want and pursue our dreams. If we want to raise up socially and  emotionally strong students who can face up and overcome  the hardships of life, an important key in this is to teach (and model) them about failure. We need to show them that failure is a healthy sign and a good omen for a healthy life experience. They need to view failure as an attempt for deep reflection and meditation about what work or did not work. They also need to be reminded that failure has been a common denominator behind most of the historical achievements and invention in the history of humankind."

"If you are planning to incorporate iPad in your classroom teaching then you definitely need to work on some preliminary stuff before anything else. These are basically formalities and conventions students need to abide by when using iPad in class. Making students explicitly aware of their responsibilities behind using iPad in class will certainly help you tap into the full educational potential of this versatile gadget. I have gone through my archive and picked out these handy visuals for you to use with your students."

"On a number of occasions I've blogged about the incredible possibilities that a large screen display brings to a PE practical classroom. With this in mind, I thought I would create a video exploring 10 ways can use a large screen display in your PE Classes. I also go behind the setup at my School and the various ways I've used it to enhance my teaching and my students learning. You can watch the video below"

"I've previously posted several times about how much I love the Shadow Puppet app - there isn't anything out there that's an easier tool for creating a quick audio-narrated slideshow. It's perfect for English Language Learners. Today, the company behind Shadow Puppet has just released another new and free educational app that looks like it could be very useful. It's called Seesaw, and basically lets students easily create digital portfolios that can be shared with teachers and parents. It's free for teachers and students, and has a free and paid version for parents."

""Failing Forward" is a relatively recent entry into our cultural lexicon-at least as far has headlines go anyway-that has utility for students and teachers. Popularized from the book of the same name, the idea behind failing forward is to see failing as a part of success rather than its opposite. Provided we keep moving and pushing and trying and reflecting, failure should, assuming we're thinking clearly, lead to progress, So rather than failing and falling back, we fail forward. Tidy little metaphor. So what might this look like in your classroom?"
