Conflict-Free And Easy To Repair, The Fairphone Is The World's Most Ethical Phone | Co.... - 0 views

  •  
    "The Fairphone is a modular handset designed with repairability and ethical sourcing of its materials as headline features. It sold 60,000 units. Amazingly, for what sounds like a nerd-phone, almost half of those buyers had never owned a smartphone before. Now the Fairphone 2 is launching, and with a totally-new, in-house design. The new phone is even easier to repair, and because it was wholly designed by the FairPhone team, its supply chain is even more responsible than ever. The Fairphone is thicker than the latest iPhone or Samsung flagship, but that's the point. Instead of packing everything into a tiny case and keeping it there with glue, the Fairphone is designed to be taken apart. The lightweight magnesium frame supports modules that can be easily replaced by the user. "We have designed it with an aim to last three to five years, looking at making it robust and modular-for repairability," says Fairphone's chief communications officer, Tessa Wernink. "Obviously how long it lasts depends quite heavily on the user, so what we as a company are doing is offering an ecosystem around the phone that supports long-lasting use, first-hand or second-hand." Inside the case (itself one of several options) you'll find the core unit, containing all the chips and radios; a replaceable battery pack; a display that can be snapped off and replaced without any tools (not even a screwdriver); a receiver unit, which contains the front camera, sensors; the headset connector and microphones; a speaker/vibrator unit; and a camera module. These modules are designed to balance manufacturing complexity with repairability. For instance, the display comes as a standalone unit, but less-vulnerable components are bundled into one module. The camera, which people are most likely to upgrade as better versions become available, is also housed in its own module. That way you don't need to toss out your whole phone just to get a better camera. "In fact, the motto from the maker mo

What's Wrong With Latin American Early Education - 0 views

  •  
    "Back in the 1980s, a group of social workers in Jamaica visited low-income homes one hour a week for two years, bearing age-appropriate toys for the kids and advice on child rearing for the parents. Researchers tracked the outcomes, and a generation later, the results are in. The children whose homes were visited by social workers became adults who earn wages that are 25 percent higher than those earned by peers who had not been visited. Their I.Q.s are an average seven points higher, and they are less likely to resort to crime or suffer from depression. Other studies, including several recent ones in the United States, have shown similar results, contributing to a consensus on the importance of early childhood development that has led governments around the world to increase spending on the first five years of life. In Latin America and the Caribbean, a region of longstanding social and economic inequality, several countries have been especially ambitious. Brazil and Chile doubled the coverage of day care services over the past decade, while in Ecuador they grew sixfold. These investments build on historic gains in child nutrition and health. But while Latin American children are now healthier and more likely to attend preschool, they still lag far behind in learning, particularly in the areas of language and cognition, when compared with their counterparts in wealthy countries.

Close Reading and Argument Writing - Authentically Across the Curriculum - Gu... - 0 views

  •  
    "Close Reading and Argument Writing - Authentically Across the Curriculum 7/16/2015 0 Comments Close reading of informational texts and non-fiction articles is not - and should not be - reserved for language arts classes. Every content area would be immensely enhanced if science teachers, social studies teachers, physical education teachers, welding teachers, woodworking teachers (in other words, "all technical subjects," as Common Core states) would not push aside the textbook, but instead embrace it, along with content area and trade articles. Students would then simultaneously learn how to dissect the readings while gaining knowledge in these content areas. What often happens is that teachers feel that students can't handle the text books or can't read the articles independently - and often that is true. However, when teachers instead go into a survival mode, of sorts, and read aloud the whole chapter or article or summarize it with a slideshow, it ends up doing a disservice to students - students are not learning HOW to read these complex texts. They are not learning how to acquire the information on their own. They are not being given the skills to read the sometimes intricate information within a particular content area or even within their possible future trade. They are not being given the opportunity to read, understand, articulate, and discuss or even debate topics within their area of study. Teachers sometimes feel that they can't do these things with students because they are not language arts teachers, or because they don't have time, or simply because they don't know how. Alternatively, a simple solution is to let go of the control and let students do…..with the guidance called close reading. Close reading is a guided reading approach. It is guided because 1) the close reading strategy is reserved for complex texts that are often too high for students to be left with independently and 2) students don't use close reading strateg

Eleven Ways to Improve Online Classes - 0 views

  •  
    "It has me thinking about what it would mean to improve online classes. A few ideas come to mind: Use multiple platforms. I'm not against using an LMS as a central hub. However, I think it's valuable to experiment with the types of productivity tools you will actually use outside of a classroom. Use Google Docs to share ideas, create surveys, and ask questions. Use Google Hangouts to meet as a group. Go project-based. I haven't figured this out entirely with my first class but my hope is that we can go fully project-based in the same way that my face-to-face class is. In fact, the asynchronous nature of online classes actually means there is a better potential of creating a project-based culture that mirrors the way people actually work on projects. Make something together. I use a collaboration grid with co-creating and communicating on separate spectrums (x-axis) and multimedia and text on another spectrum (y-axis). This has been an effective way to think through collaborative tools that allow students to co-create. Embrace a synchronous/asynchronous blend: I love using Voxer because students can speak back and forth in the moment. However, if they miss it, they can listen to it later. The same is true of using a Google Hangouts On Air. Make it more connective. We tend to treat online instruction as if it is a linear process and we don't do enough to link things back and forth and connect ideas, resources, discussions and content creation in a seamless, back-and-forth nature. Incorporate multimedia. It's a simple idea, but I create a short video at the beginning of each week and I encourage students to create video and audio as well. This has a way of making things more concrete. There's something deeply human about hearing an actual human voice. I know, crazy, right? Go mobile. I don't simply mean use a smart phone. I mean assign some things that allow students to get out in the world and create videos, snap pictures,

Although many can turn their blogs into a revenue stream by offering goods and services somewhere in the mix, there are various reasons you might not be in a position to do so. For example, you may not be running a commercial business. You could be managing a non-profit organization or have no current goods or services to monetize. Many designers, writers, and voluntary groups find themselves in this situation and need to explore alternative sources of income. Donations are one of the most common ways to do just that, and they can sometimes even be more effective than ads or sponsored posts. If your readers are ready to put their hands in their pockets, you just need to provide the means. In this article, we've gathered together five of the best WordPress donation plugins to help you make that process simple. Why Use a Tip Jar? At first you might have some reservations about placing a donation button on your website. Some might feel it's in poor taste - as if you're begging your readers for help. Others doubt that it'll work, thinking readers will automatically ignore it. But the truth is that a tip jar is a great way to garner support for your WordPress site. It can provide supplemental income if you're a freelance designer or developer, and the amount brought in over the course of a month or year can offset hosting costs for your website. Furthermore, with the growing use of ad blockers, donations can be more effective than traditional online revenue streams. For startups and non-profit groups, donations are a vital means of funding campaigns. Other sites may choose to use tip jar

Small Changes in Teaching: The Last 5 Minutes of Class - 0 views

  •  
    "The Minute Paper comes in many variations, but the simplest one involves wrapping up the formal class period a few minutes early and posing two questions to your students: What was the most important thing you learned today? What question still remains in your mind? Taken together, those two questions accomplish multiple objectives. The first one not only requires students to remember something from class and articulate it in their own words (more about that in a moment), but it also requires them to do some quick thinking. They have to reflect on the material and make a judgment about the main point of that day's class. The second question encourages them to probe their own minds and consider what they haven't truly understood. Most of us are infected by what learning theorists sometimes call "illusions of fluency," which means that we believe we have obtained mastery over something when we truly have not. To answer the second question, students have to decide where confusion or weaknesses remain in their own comprehension of the day's material. Closing connections. If we want students to obtain mastery and expertise in our subjects, they need to be capable of making their own connections between what they are learning and the world around them - current events, campus debates, personal experiences. The last five minutes of class represent an ideal opportunity for students to use the course material from that day and brainstorm some new connections.The metacognitive five. We have increasing evidence from the learning sciences that students engage in poor study strategies. Likewise, research shows that most people are plagued by the illusions of fluency. The solution on both fronts is better metacognition - that is, a clearer understanding of our own learning. What if all of us worked together deliberately to achieve that?Close the loop. Finally, go back to any of the strategies I introduced in my recent column on the first five minutes of clas

Male Singing To Female That Will Never Come | Racing Extinction - 1 views

    "The Kaua Moho was the last species of it's entire genus and it was the last genus in it's family. This male was not just the last of his kind, he was the last being on his entire branch of the evolutionary tree, there was nothing left on the planet that was even close to being like him. That kind of loneliness is unimaginable. No other avian family has had every single species within it go completely extinct in modern times. Different species of Moho lived on each island of Hawaii and their evolutionary cousins the kioea birds lived alongside them, but starting in 1800 (about the time Europeans started arriving to the islands in significant numbers and also about the time the native human population of Hawaii also got decimated by diseases) one by one they died out due to the introduction of foreign avian diseases and parasites, habitat loss, and hunting for their plumage. 2 hurricanes within 10 years of each other finished them off. They are all gone and that song or any song like it will never be heard again save for in recordings. The hurricanes dealt the final blow, but 95% of it was humanity's fault. This has become common in Hawaii due to having so many species that only exist there. A LOT of those species are gone now because the arrival of Europeans brought disease, invasive species, and people straight up killed them or destroyed their habitats. It is a similar situation on every isolated island or area in the world as humans have expanded and explored every nook and cranny on the planet, no matter how hard it is to get to or how little business we have there we feel the need to interfere in even the most delicate and tiny ecosystem. Even the large, continent sized ecosystems are suffering. It doesn't matter if there are millions or even billions of an animal or plant, we will find some way to kill them all. It is only in the last few decades that serious steps have finally been taken to preserve the few areas on this world that we have not destroyed, but

Poverty Impedes Cognitive Function | Science - 0 views

  •  
    "Burden of Poverty Lacking money or time can lead one to make poorer decisions, possibly because poverty imposes a cognitive load that saps attention and reduces effort. Mani et al. (p. 976; see the Perspective by Vohs) gathered evidence from shoppers in a New Jersey mall and from farmers in Tamil Nadu, India. They found that considering a projected financial decision, such as how to pay for a car repair, affects people's performance on unrelated spatial and reasoning tasks. Lower-income individuals performed poorly if the repairs were expensive but did fine if the cost was low, whereas higher-income individuals performed well in both conditions, as if the projected financial burden imposed no cognitive pressure. Similarly, the sugarcane farmers from Tamil Nadu performed these tasks better after harvest than before. Abstract The poor often behave in less capable ways, which can further perpetuate poverty. We hypothesize that poverty directly impedes cognitive function and present two studies that test this hypothesis. First, we experimentally induced thoughts about finances and found that this reduces cognitive performance among poor but not in well-off participants. Second, we examined the cognitive function of farmers over the planting cycle. We found that the same farmer shows diminished cognitive performance before harvest, when poor, as compared with after harvest, when rich. This cannot be explained by differences in time available, nutrition, or work effort. Nor can it be explained with stress: Although farmers do show more stress before harvest, that does not account for diminished cognitive performance. Instead, it appears that poverty itself reduces cognitive capacity. We suggest that this is because poverty-related concerns consume mental resources, leaving less for other tasks. These data provide a previously unexamined perspective and help explain a spectrum of behaviors among the poor. We discuss some implications for poverty policy."

    "Call it counterintuitive clickbait if you must, but Forbes' Pascal-Emmanuel Gobry made an intriguing argument when he granted the title of "Language of the Future" to French, of all tongues. "French isn't mostly spoken by French people and hasn't been for a long time now," he admits," but "the language is growing fast, and growing in the fastest-growing areas of the world, particularly sub-Saharan Africa. The latest projection is that French will be spoken by 750 million people by 2050. One study "even suggests that by that time, French could be the most-spoken language in the world, ahead of English and even Mandarin." I don't know about you, but I can never believe in any wave of the future without a traceable past. But the French language has one, of course, and a long and storied one at that. You see it visualized in the information graphic above (also available in suitable-for-framing prints!) created by Minna Sundberg, author of the webcomic Stand Still. Stay Silent. "When linguists talk about the historical relationship between languages, they use a tree metaphor," writes Mental Floss' Arika Okrent.

A recent Pew Research Center survey found that 58% of U.S. teachers own smartphones - 10 percentage points higher than the national average for adults.

    "Contents:Notebook of Leonardo da Vinci ('The Codex Arundel'). A collection of papers written in Italian by Leonardo da Vinci (b. 1452, d. 1519), in his characteristic left-handed mirror-writing (reading from right to left), including diagrams, drawings and brief texts, covering a broad range of topics in science and art, as well as personal notes. The core of the notebook is a collection of materials that Leonardo describes as 'a collection without order, drawn from many papers, which I have copied here, hoping to arrange them later each in its place according to the subjects of which they treat' (f. 1r), a collection he began in the house of Piero di Braccio Martelli in Florence, in 1508. To this notebook has subsequently been added a number of other loose papers containing writing and diagrams produced by Leonardo throughout his career. Decoration: Numerous diagrams. "

Small Changes in Teaching: The First 5 Minutes of Class - 0 views

  •  
    "Open with a question or two. Another favorite education writer of mine, the cognitive psychologist Daniel Willingham, argues that teachers should focus more on the use of questions. "The material I want students to learn," he writes in his book Why Don't Students Like School?, "is actually the answer to a question. On its own, the answer is almost never interesting. But if you know the question, the answer may be quite interesting." My colleague Greg Weiner, an associate professor of political science, puts those ideas into practice. At the beginning of class, he shows four or five questions on a slide for students to consider. Class then proceeds in the usual fashion. At the end, he returns to the questions so that students can both see some potential answers and understand that they have learned something that day. What did we learn last time? A favorite activity of many instructors is to spend a few minutes at the opening of class reviewing what happened in the previous session. That makes perfect sense, and is supported by the idea that we don't learn from single exposure to material - we need to return frequently to whatever we are attempting to master.But instead of offering a capsule review to students, why not ask them to offer one back to you?Reactivate what they learned in previous courses. Plenty of excellent evidence suggests that whatever knowledge students bring into a course has a major influence on what they take away from it. So a sure-fire technique to improve student learning is to begin class by revisiting, not just what they learned in the previous session, but what they already knew about the subject matter.Write it down. All three of the previous activities would benefit from having students spend a few minutes writing down their responses. That way, every student has the opportunity to answer the question, practice memory retrieval from the previous session, or surface their prior knowledge - and not just the students most likely to

The UAE is investing $100 million in indoor farming - 0 views

    "With little water, scorching temperatures, and not much arable land, the UAE currently imports 80% of its food. Can it go local? In an industrial park built off a highway in the arid land between Abu Dhabi and Dubai, a sprawling new indoor farm will soon grow tomatoes under LED lights in a climate-controlled warehouse near a plastic production facility and other factories. The farm, the first in the world to commercially grow tomatoes solely under artificial light, is one part of a push to transform food production in the United Arab Emirates, where 80% of food is imported. The government realizes that to be resilient, it will need to find new ways to grow food in a desert climate with little rain and temperatures that regularly stay above 100 degrees."

    "Max Roser (2016) - 'World Poverty'. Published online at OurWorldInData.org. Retrieved from: http://ourworldindata.org/data/growth-and-distribution-of-prosperity/world-poverty/ In the past only a small elite lived a life without poverty. Since the onset of industrialization - and as a consequence of this, economic growth1 - the share of people living in poverty started decreasing and has kept on falling ever since. But as a consequence of falling poverty, the health of the population improved dramatically over the last two centuries, and the population started to grow.2 The growth of the population caused the absolute number of poor people in the world to increase; only recently has the absolute number of people living in poverty started to fall as well.

    "Max Roser (2016) - 'World Poverty'. Published online at OurWorldInData.org. Retrieved from: http://ourworldindata.org/data/growth-and-distribution-of-prosperity/world-poverty/ In the past only a small elite lived a life without poverty. Since the onset of industrialization - and as a consequence of this, economic growth1 - the share of people living in poverty started decreasing and has kept on falling ever since. But as a consequence of falling poverty, the health of the population improved dramatically over the last two centuries, and the population started to grow.2 The growth of the population caused the absolute number of poor people in the world to increase; only recently has the absolute number of people living in poverty started to fall as well. This data entry chronicles the falling poverty over the last centuries."

France to End Disposal of $900 Million in Unsold Goods Each Year - 0 views

  •  
    "France plans to outlaw the destruction of unsold consumer products, a practice that currently results in the disposal of new goods worth 800 million euros, or more than $900 million, in the country each year. By 2023, manufacturers and retailers will have to donate, reuse or recycle the goods, Prime Minister Édouard Philippe said on Tuesday of the measure, which the government billed as the first of its kind. "It is waste that defies reason," Mr. Philippe said at a discount store in Paris, according to Agence France-Presse, and he called the practice "scandalous." Under a new measure that will be part of a bill set to be debated by the government in July, destroying unsold goods could result in financial penalties or prison time. The practice - widespread across the retail and consumer industry as a way to free up warehouse space or prevent unwanted items from being sold at a significant discount - has received bad press in France recently. ..."

ECO - Announcing A New World - Strange Loop Games - 0 views

    "What does that mean exactly? It means you play in a multiplayer world that has the possibility of being permanently destroyed, resulting in server-wide perma death. What's more, the reason it's destroyed would be the players' own fault. It's not that different from our own world in that way. "This ecosystem is your only lifeline in a race against time." It works like this: a new server is started, and players enter at the beginnings of civilization. There's a world-destroying cataclysm looming, like a drought or a flood or a meteor heading for the Earth, several real-time weeks away. In order to prevent that catastrophe from happening, you need to build a civilization and advance technology and resources to the point that the crisis can be averted. However you're not alone in this world. Besides the other players, you'll be sharing the world with a detailed wilderness simulation full of plants and animals. They simulate 24 hours a day, living out their lives with or without human interaction, growing, feeding and reproducing. Together they form an ecosystem rich with resources, resources that you must use to survive and develop a civilization."

Cloud Loss Could Add 8 Degrees to Global Warming - 0 views

    "A state-of-the-art supercomputer simulation indicates that a feedback loop between global warming and cloud loss can push Earth's climate past a disastrous tipping point in as little as a century. On a 1987 voyage to the Antarctic, the paleoceanographer James Kennett and his crew dropped anchor in the Weddell Sea, drilled into the seabed, and extracted a vertical cylinder of sediment. In an inch-thick layer of plankton fossils and other detritus buried more than 500 feet deep, they found a disturbing clue about the planet's past that could spell disaster for the future. Lower in the sediment core, fossils abounded from 60 plankton species. But in that thin cross-section from about 56 million years ago, the number of species dropped to 17. And the planktons' oxygen and carbon isotope compositions had dramatically changed. Kennett and his student Lowell Stott deduced from the anomalous isotopes that carbon dioxide had flooded the air, causing the ocean to rapidly acidify and heat up, in a process similar to what we are seeing today."

    These 'warming stripe' graphics are visual representations of the change in temperature as measured in each country over the past 100+ years. Each stripe represents the temperature in that country averaged over a year. For most countries, the stripes start in the year 1901 and finish in 2018. For the UK, USA, Switzerland & Germany, the data starts in the late 19th century.
