    What is really happening in schools around the world? How many are being attacked? Why do people attack schools? If you want to understand the true nobility of teaching -- see this article. We are viewed as symbols of progress and community leadership. Attack us and you attack a community. It is heartbreaking but also at the same time, cognizant of the true leadership of teachers in our world today.

    What's a hashtag? Hashtags are a community-driven convention for adding additional context and metadata to your tweets. They're like tags on Flickr, only added inline to your posts. Hashtags can be created by anyone simply by prefixing a word with a hash symbol: #myhashtag.

  • For the home user, however, password safety requires more than on-the-fly thinking. Pacheco suggests a system built around a main word for all instances. The distinction is that the name of the site is added somewhere. For example, if the main word is "eggplant," the password might be "eggyyplant" Yahoo, "eggplantgg" for Google or "wleggplant" for Windows Live. He suggests listing the variations in an Excel spreadsheet.
  • Password security is a big deal, and if you don't think it is, then someone might be hacking into your computer even as you read this. A strong password isn't foolproof, but it proves that you're no fool. And it might protect you from compromised data, a broken computer or identity theft. Your bank account, your personal e-mails and lots of other stuff are at risk with weak passwords.
  • "A good password is the most important part of Internet security," said Robert Pacheco, the owner of Computer Techs of San Antonio. "It's the beginning and end of the issue. You can't stop it (hacking). You do what you can do to prevent it. You just try to stop most of it." A strong firewall, as well as spyware -- and virus-detection software -- protect a computer's so-called "back door," Pacheco said, where a hacker can gain access through various cyber threats. Those threats include infected e-mail attachments; phishing Web pages that exploit browser flaws; downloaded songs or pictures with hidden trojans; or plain ol' poking-and-prodding of a computer's shields. But passwords protect information from a frontal assault by way of the computer's keyboard.

  • Other people use easy-to-remember passwords. Trouble is, Rogers said, they're easy-to-guess passwords, too. Good examples of bad passwords are your name, your family's names, your pet's name, the name of your favorite team, your favorite athlete or your favorite anything. Get to know the person -- a technique that geeks refer to as "social engineering" -- and the password is easy to guess. There are message-board stalkers who can guess passwords in a half-dozen tries. Hackers rely on a lot of methods. Some, Rogers said, employ "shoulder surfing." That means what it sounds like -- looking over someone's shoulder as that person is typing in a password.

  • The type of hardware being used can be a clue, said Rogers, a senior technical staffer in the CERT Program, a Web security research center in Carnegie-Mellon University's software engineering institute. It's easy to find a default password, typically in the user's manual on a manufacturer's Web site. If the user hasn't changed the default, that's an easy break-in.

  • Most of the password hacking activity these days goes on at homes, in school or in public settings. These days, many workplaces mandate how a password is picked.
  • The idea is to choose a password that contains at least one uppercase letter, one numeral and at least eight total characters. Symbols are good to throw in the mix, too. Many companies also require that passwords be changed regularly and that pieces of older ones can't be re-used for months. And user names cannot be part of the password. Examples: Eggplant99, 99eggpLanT, --eggp--99Lant. For the next quarter, the password might change to variations on "strawberry.

  • To refuse to try, to stick (97) blindly to tradition, because the search for the truth involves experimentation in the region of the unknown, is to refuse the only step which can introduce rational conviction into education.

      great quote
  • It should also be stated that practically it has not as yet been possible, in many cases, to act adequately upon the best ideas obtained, because of administrative difficulties, due to lack of funds —difficulties centering in the lack of a proper building and appliances, and in inability to pay the amounts necessary to secure the complete time of teachers in some important lines. Indeed, with the growth of the school in numbers, and in the age and maturity of pupils, it is becoming a grave question how long it is fair to the experiment to carry it on without more adequate facilities.
  • The aim, then, is not for the child to go to school as a place apart, but rather in the school so to recapitulate typical phases of his experience outside of school, as to enlarge, enrich, and gradually formulate it.

  • His experiments are modes of active doing—almost as much so as his play and games. Later he tries to find out how various materials or agencies are manipulated in order to give certain results. It is thus clearly distinguished from experimentation in the scientific sense—such as is appropriate to the secondary period —where the aim is the discovery of facts and verification of principles.

  • These subjects are social in a double sense. They represent the tools which society has evolved in the past as the instruments of its intellectual pursuits. They represent the keys which will unlock to the child the wealth of social capital which lies beyond the possible range of his limited individual experience. While these two points of view must always give these arts a highly important place in education, they also make it necessary that certain conditions should be observed in their introduction and use. In a wholesale and direct application of the studies no account is taken of these conditions. The chief problem at present relating to the three R's is recognition of these conditions and the adaptation of work to them.
  • 1) The need that the child shall have in his own personal (105) and vital experience a varied background of contact and acquaintance with realities, social and physical. This is necessary to prevent symbols from becoming a purely second-hand and conventional substitute for reality.
  • The need that the more ordinary, direct, and personal experience of the child shall furnish problems, motives, and interests that necessitate recourse to books for their solution, satisfaction, and pursuit. Otherwise, the child approaches the book without intellectual hunger, without alertness, without a questioning attitude, and the result is the one so deplorably common: such abject dependence upon books as weakens and cripples vigor of thought and inquiry, combined with reading for mere random stimulation of fancy, emotional indulgence, and flight from the world of reality into a make-belief land.
  • The final use of the symbols, whether in reading, calculation, or composition, is more intelligent, less mechanical; more active, less passively receptive; more an increase of power, less a mere mode of enjoyment.

    dynamic mathematics software for all levels of education that joins arithmetic, geometry, algebra and calculus. It offers multiple representations of objects in its graphics, algebra, and spreadsheet views that are all dynamically linked. While other interactive software (e.g. Cabri Geometry, Geometer's Sketchpad) focus on dynamic manipulations of geometrical objects, the idea behind GeoGebra is to connect geometric, algebraic, and numeric representations in an interactive way. You can do constructions with points, vectors, lines, conic sections as well as functions and change them dynamically afterwards. Furthermore, GeoGebra allows you to directly enter and manipulate equations and coordinates. Thus you can easily plot functions, work with sliders to investigate parameters, find symbolic derivatives, and use powerful commands like Root or Sequence. Workshops You are interested in visiting or giving workshops about GeoGebra? Here is the right place for you with dates, addresses and materials: * GeoGebra Workshops

    For students to make connections in algebraic thinking in problem solving situations, it is important they learn to use algebra symbolism to represent known and unknown information. To this end they must express problem solving situations as linear, quadratic, or exponential models. This way of thinking also requires students to model, represent, analyze, and generalize contextualized problems in a variety of problem solving situations as they begin to think algebraically.

    Learning algebra is difficult for most students. Ask any student what they are learning in algebra and you will probably receive an answer similar to this (after - Why do I need to know this?). "Using Xs and Ys a lot, a bunch of numbers and symbols, and memorizing a lot of rules." This often comes with learning algebra without connection to anything students can relate to. When students learn basic math, they can make a lot of connections.

    "August 1, 2011, 5:51 pm By Rachel Wiseman College students with very poor vision have had to struggle to see a blackboard and take notes-basic tasks that can hold some back. Now a team of four students from Arizona State University has designed a system, called Note-Taker, that couples a tablet PC and a video camera, and could be a major advance over the small eyeglass-mounted telescopes that many students have had to rely on. It recently won second place in Microsoft's Imagine Cup technology competition. (...) The result was Note-Taker, which connects a tablet PC (a laptop with a screen you can write on) to a high-resolution video camera. Screen commands get the camera to pan and zoom. The video footage, along with audio, can be played in real time on the tablet and are also saved for later reference. Alongside the video is a space for typed or handwritten notes, which students can jot down using a stylus. That should be helpful in math and science courses, says Mr. Hayden, where students need to copy down graphs, charts, and symbols not readily available on a keyboard. (...) But no tool can replace institutional support, says Chris S. Danielsen, director of public relations for the [NFB]. "The university is always going to have to make sure that whatever technology it uses is accessible to blind and low-vision students," he says. (Arizona State U. has gotten in hot water in the past in just this area.) (...) This entry was posted in Gadgets."

The Progressive Stack and Standing for Inclusive Teaching - The Tattooed Professor - 2 views

pedagogy inclusion

shared by Ed Webb on 15 May 20 - Cached
  • There are two fundamental truths about Inclusive Pedagogy: it is an eminently desirable set of practices for teaching in higher ed, and it is an eminently difficult set of practices for teaching in higher ed
  • Put simply, the Progressive Stack is a method of ensuring that voices that are often submerged, discounted, or excluded from traditional classroom discussions get a chance to be heard
  • There are personal, cultural, learning, and social reasons people don’t speak up in class.  Students of color and women of all races, introverts, the non-conventional thinkers, those from poor previous educational backgrounds, returning or “nontraditional students,” and those from cultures where speaking out is considered rude not participatory are all likely to be silent in a class where collaboration by difference is not structured as a principle of pedagogy and organization and design.   Who loses?  Everyone.  Arguments that are smart and valuable and can change a whole conversation get lost in silence and, sometimes, shame.  When that happens, we don’t really have discussion or collaboration.  We have group think–and that is why we all lose.

  • Taking “stack” just means keeping a list of people who wish to participate—offer a question or comment—during the Q & A. Rather than anxiously waving your hand around and wondering if you’ll be called on, if you would like to participate, signal to me in some way (a gesture, a dance move, a traditional hand-in-the-air, meaningful eye contact, etc.) and I will add you to the list. However, we’re not just going to take stack, we are going to take progressive stack in an effort to foreground voices that are typically silenced in dominant culture. According to Justine and Zoë, two self-identified transwomen who were active in the movement, progressive stack means that “if you self-identify as trans, queer, a person of color, female, or as a member of any marginalized group you’re given priority on the list of people who want to speak – the stack. The most oppressed get to speak first.” As I take stack, I will also do my best to bump marginalized voices and those who haven’t yet had a chance to participate to the top.
  • As with any tool that confronts the effects of privilege and power head-on, the Progressive Stack makes some people uncomfortable
  • In a complete social and historical vacuum, level-playing-field equality is an excellent proposition. But in the actual lived world of our history, experiences, and interactions the idea of treating everyone uniformly “regardless of gender” or without “seeing color” simply strengthens already-entrenched inequalities
  • As the increasing number of targeted online harassment campaigns has shown us, once a concept or issue has traveled through the right-wing Outrage-Distortion Complex, there is little hope of reclaiming rational discussion. It’s been permanently stained. One might dismiss the frothing lamentations of white-genocide-via-classroom-pedagogy that bubble up from a subreddit, but the insidious trope of “reverse racism” has put its thumb on the scale enough to have distorted the conversation around the Progressive Stack
  • because the Progressive Stack calls attention to existing structures of inequality by replacing them with another structure entirely, it forces those of us who identify as white (and, particularly, male) to confront the ways in which we have been complicit in maintaining inequality
  • When you’re accustomed to privilege, even the suggestion of equality will feel like oppression
  • google “progressive stack.” Almost every result you get will take you to the fever swamps of right-wing Reddit and warmed-over piles of gamergate droppings. The common denominator is that “Progressive Stack” is simply anti-white “racism” dressed in fancy intellectual clothes
  • Giving up power, it turns out, is hard for some people. Especially when that power has been historically-constructed to be so pervasive as to render it unquestioned and indeed unseen in its hegemonic sway. Pierre Bourdieu calls this symbolic power: “For symbolic power is that invisible power which can be exercised only with the complicity of those who do not want to know that they are subject to it or even that they themselves exercise it”
  • It means there will be times when people who are not accustomed to their identity being a source of discomfort and exclusion will have to learn–in a managed and intentional space–what that feels like.
  • there will be friction and messiness and uncomfortable adjustments, because any education worth the name involves friction and messiness and uncomfortable adjustments
