Your Laptop's Dirty Little Secret - TIME - 1 views

  • Phones and computers contain dangerous metals like lead, cadmium and mercury, which can contaminate the air and water when those products are dumped. It's called electronic waste, or e-waste, and the world produces a lot of it: 20 to 50 million tons a year, according to the UN — enough to load a train that would stretch around the world. The U.S. is by far the world's top producer of e-waste, but much of it ends up elsewhere — specifically, in developing nations like China, India and Nigeria, to which rich countries have been shipping garbage for years.

Using Groups Effectively: 10 Principles « The Window - 12 views

  • Think threefold. Group tasks that produce the best results often have three defining characteristics: 1) they are novel, something students have not done before, 2) they feature a visual component, something that can be represented in nonverbal forms, and 3) they are relational, meaning they require the combining of ideas or components to be accomplished.

Doing Digital Scholarship: Presentation at Digital Humanities 2008 « Digital ... - 0 views

  • My session, which explored the meaning and significance of “digital humanities,” also featured rich, engaging presentations by Edward Vanhoutte on the history of humanities computing and John Walsh on comparing alchemy and digital humanities.
  • I wondered: What is digital scholarship, anyway?  What does it take to produce digital scholarship? What kind of digital resources and tools are available to support it? To what extent do these resources and tools enable us to do research more productively and creatively? What new questions do these tools and resources enable us to ask? What’s challenging about producing digital scholarship? What happens when scholars share research openly through blogs, institutional repositories, & other means?
  • I decided to investigate these questions by remixing my 2002 dissertation as a work of digital scholarship.  Now I’ll acknowledge that my study is not exactly scientific—there is a rather subjective sample of one.  However, I figured, somewhat pragmatically, that the best way for me to understand what digital scholars face was to do the work myself.

  • The ACLS Commission on Cyberinfrastructure’s report points to five manifestations of digital scholarship: collection building, tools to support collection building, tools to support analysis, using tools and collections to produce “new intellectual products,” and authoring tools. 
  • Tara McPherson, the editor of Vectors, offered her own “Typology of Digital Humanities”: •    The Computing Humanities: focused on building tools, infrastructure, standards and collections, e.g. The Blake Archive •    The Blogging Humanities: networked, peer-to-peer, e.g. crooked timber •    The Multimodal Humanities: “bring together databases, scholarly tools, networked writing, and peer-to-peer commentary while also leveraging the potential of the visual and aural media that so dominate contemporary life,” e.g. Vectors
  • My initial diagram of digital scholarship pictured single-headed arrows linking different approaches to digital scholarship; my revised diagram looks more like spaghetti, with arrows going all over the place.  Theories inform collection building; the process of blogging helps to shape an argument; how a scholar wants to communicate an idea influences what tools are selected and how they are used.
  • I looked at 5 categories: archival resources as well as primary and secondary books and journals.   I found that with the exception of archival materials, over 90% of the materials I cited in my bibliography are in a digital format.  However, only about 83% of primary resources and 37% of the secondary materials are available as full text.  If you want to do use text analysis tools on 19th century American novels or 20th century articles from major humanities journals, you’re in luck, but the other stuff is trickier because of copyright constraints.
  • I found that there were some scanning errors with Google Books, but not as many as I expected. I wished that Google Books provided full text rather than PDF files of its public domain content, as do Open Content Alliance and Making of America (and EAF, if you just download the HTML).  I had to convert Google’s PDF files to Adobe Tagged Text XML and got disappointing results.  The OCR quality for Open Content Alliance was better, but words were not joined across line breaks, reducing accuracy.  With multi-volume works, neither Open Content Alliance nor Google Books provided very good metadata.
  • To make it easier for researchers to discover relevant tools, I teamed up with 5 other librarians to launch the Digital Research Tools, or DiRT, wiki at the end of May.

Seth's Blog: The future of the library - 15 views

  • They need a librarian more than ever (to figure out creative ways to find and use data). They need a library not at all.
  • Librarians that are arguing and lobbying for clever ebook lending solutions are completely missing the point. They are defending library as warehouse as opposed to fighting for the future, which is librarian as producer, concierge, connector, teacher and impresario.
  • Post-Gutenberg, the scarce resource is knowledge and insight, not access to data.
  • ...2 more annotations...
  • The next library is a house for the librarian with the guts to invite kids in to teach them how to get better grades while doing less grunt work. And to teach them how to use a soldering iron or take apart something with no user servicable parts inside. And even to challenge them to teach classes on their passions, merely because it's fun. This librarian takes responsibility/blame for any kid who manages to graduate from school without being a first-rate data shark.
  • The next library is filled with so many web terminals there's always at least one empty. And the people who run this library don't view the combination of access to data and connections to peers as a sidelight--it's the entire point.

Why hard work and specialising early is not a recipe for success - The Correspondent - 0 views

  • dispelling nonsense is much harder than spreading nonsense.
  • a worldwide cult of the head start – a fetish for precociousness. The intuitive opinion that dedicated, focused specialists are superior to doubting, daydreaming Jacks-of-all-trades is winning
  • astonishing sacrifices made in the quest for efficiency, specialisation and excellence
  • ...20 more annotations...
  • Most things that people want to learn do not resemble language, golf or chess, but rather a game in which the generalist has an advantage. A hostile learning environment
  • Seemingly inefficient things are productive: expanding your horizons, giving yourself time, switching professions. 
  • early specialisation is a good idea if you want to become successful in certain fields, sports or professions. In fact, in some cases, it’s the only option. Take chess, for example: if you don’t start early, you won’t stand a chance at glory.
  • learning chess is not a good model for learning other things. Epstein explains this using the work of psychologist Robin Hogarth, who makes the distinction between friendly (kind) and unfriendly or hostile (wicked) learning environments.
  • In a friendly learning environment, such as chess, the rules are clear, the information is complete (all pieces are visible on the board), and you can (ultimately) determine the quality of every move. In other words, the feedback loop
  • friendly learning environments are the exception. The world is not as clear-cut as golf or chess. So early specialisation is often a bad idea. 
  • In hostile learning environments without repetitive patterns, mastery is much harder to achieve. The feedback loop is insidious. Unlike chess, experience does not necessarily make you better. You may stick with the wrong approach because you’re convinced it’s the right one. 
  • The better a teacher scored on their own subject (i.e., the higher the grades their students got in that subject), the more mediocre students’ scores were across the complete programme (all modules). The explanation? Those teachers gave their students rigidly defined education, purely focused on passing exams. The students passed their tests with high marks – and rated their teachers highly in surveys – but would fail later on. 
  • In learning environments without repetitive patterns, where cause and effect are not always clear, early specialisation and spending countless hours does not guarantee success. Quite the opposite, Epstein argues. Generalists have the advantage: they have a wider range of experiences and a greater ability to associate and improvise. (The world has more in common with jazz than classical music, Epstein explains in a chapter on music.)
  • Many modern professions aren’t so much about applying specific solutions than they are about recognising the nature of a problem, and only then coming up with an approach. That becomes possible when you learn to see analogies with other fields, according to psychologist Dedre Gentner, who has made this subject her life’s work.
  • Another advantage generalists and late specialists have is more concrete: you are more likely to pick a suitable study, sport or profession if you first orient yourself broadly before you make a choice.
  • Greater enjoyment of the game is one of the benefits associated with late specialisation, along with fewer injuries and more creativity.
  • which child, teenager or person in their 20s knows what they will be doing for the rest of their lives?
  • Persevering along a chosen path can also lead to other problems: frustrations about failure. If practice makes perfect, why am I not a genius? In a critical review,
  • The tricky thing about generalist long-term thinking versus specialist short-term thinking is that the latter produces faster and more visible results.
  • specialising in short-term success gets in the way of long-term success. This also applies to education.
  • (Another example: the on-going worry about whether or not students’ degree choices are "labour market relevant".)
  • Teachers who taught more broadly – who did not teach students readymade "prescribed lessons” but instilled "principles" – were not rated as highly in their own subject, but had the most sustainable effect on learning. However, this was not reflected in the results. These teachers were awarded – logically but tragically – lower ratings by their students.
  • the 10,000 hour gang has considerable power with their message "quitters never win, winners never quit".Epstein’s more wholesome message seems weak and boring in comparison. Some things are simply not meant for everyone, doubt is understandable and even meaningful, you can give up and change your choice of work, sports or hobby, and an early lead can actually be a structural disadvantage. 
  • "Don’t feel behind." Don’t worry if others seem to be moving faster, harder or better. Winners often quit.

Xerox stepping into grading school papers - 1 views

  •  
    Grading handwritten answers by students as a feature of a copier? Producing data analytics as a result. IF this works, it will not only sell more copiers, but also make handwritten work more of a commodity. Maybe if a computer can quickly grade the easy stuff, teachers can spend more time assessing project based learning and other work that computers cannot do. This won't help me much - except when I teach binary numbers and memory conversion which do require me to check work (I never do multiple choice.) I could see how math teachers would be thrilled. "Xerox later this year plans to roll out Ignite, a software and web-based service that turns the numerous copiers/scanners/printers it has in schools across the United States into paper-grading machines. Unlike such staples of the educational system as Scantron, which uses special forms where students choose an answer and fill in the corresponding bubble, Ignite will grade work where the answers are written in by the students, such as the numeric answer to a math problem. Ignite takes right and wrong answers and turns them into web-accessible data for teachers with reports that say whether a student or groups of students are consistently having more trouble with certain kinds of math problems. Those reports can be used by teachers to tailor what they're teaching - such as by identifying what group of students needs more help with a certain topic - or given to students so they know where they should focus their studying. It also opens the door to specific tests or homework assignments for specific students becoming more the norm, each tailored to academic strengths and weaknesses."

Parents' maths skills 'rub off' on their children - 0 views

  •  
    Parents who excel at maths produce children who excel at maths. This is according to a recently released University of Pittsburgh study, which shows a distinct transfer of math skills from parent to child. The study specifically explored intergenerational transmission-the concept of parental influence on an offspring's behaviour or psychology-in mathematic capabilities.

Salute to Teachers - 3 views

  •  
    The GLOBE Program (http://www.globe.gov) is taking this opportunity to salute teachers everywhere----for all of the things you do----for inspiring your students and cultivating the love of learning. Teachers are the backbone of our educational system. They encourage, inspire and challenge us to reach new heights and dream without boundaries. The GLOBE Program Office in Boulder, Colorado produced this video for teachers everywhere. We encourage you to watch it, send it to your fellow (or favorite) teachers, school administrators, friends and family members. Encourage them to share it with their network as well so that everyone may pause for a moment and truly appreciate the teachers who made a difference in their lives.

Chile's Student Uprising: 'There's a Story to Be Told' | International Political Forum - 0 views

  •  
    Increasingly activists are becoming filmmakers because video is the modern essay - traveling further than pamphlets by Patrick Henry, showing people in action fighting for freedom - or, in this case, free education in Chile, tends to cause change. Fascinating read and case study. "Roberto's son Pablo, born and raised in the UK, has worked on several documentaries on Latin America. He produced the documentary 'Inside the Revolution: A Journey Into the Heart of Venezuela', released in August 2009 by Alborada Films, and 'The Colombia Connection', released in November 2012. He has covered Latin America for various media outlets, including Al Jazeera English, the Guardian and the BBC. I spoke to Pablo about their forthcoming documentary on Chile's student movement and their crowdfunding campaign."
