The powerful and mysterious brain circuitry that makes us love Google, Twitter, and texting. - By Emily Yoffe - Slate Magazine - 0 views

  • For humans, this desire to search is not just about fulfilling our physical needs. Panksepp says that humans can get just as excited about abstract rewards as tangible ones. He says that when we get thrilled about the world of ideas, about making intellectual connections, about divining meaning, it is the seeking circuits that are firing.
  • Our internal sense of time is believed to be controlled by the dopamine system. People with hyperactivity disorder have a shortage of dopamine in their brains, which a recent study suggests may be at the root of the problem. For them even small stretches of time seem to drag.
  • When we get the object of our desire (be it a Twinkie or a sexual partner), we engage in consummatory acts that Panksepp says reduce arousal in the brain and temporarily, at least, inhibit our urge to seek.

  • But our brains are designed to more easily be stimulated than satisfied. "The brain seems to be more stingy with mechanisms for pleasure than for desire," Berridge has said. This makes evolutionary sense. Creatures that lack motivation, that find it easy to slip into oblivious rapture, are likely to lead short (if happy) lives. So nature imbued us with an unquenchable drive to discover, to explore. Stanford University neuroscientist Brian Knutson has been putting people in MRI scanners and looking inside their brains as they play an investing game. He has consistently found that the pictures inside our skulls show that the possibility of a payoff is much more stimulating than actually getting one.
  • all our electronic communication devices—e-mail, Facebook feeds, texts, Twitter—are feeding the same drive as our searches. Since we're restless, easily bored creatures, our gadgets give us in abundance qualities the seeking/wanting system finds particularly exciting. Novelty is one. Panksepp says the dopamine system is activated by finding something unexpected or by the anticipation of something new. If the rewards come unpredictably—as e-mail, texts, updates do—we get even more carried away. No wonder we call it a "CrackBerry."
  • If humans are seeking machines, we've now created the perfect machines to allow us to seek endlessly. This perhaps should make us cautious. In Animals in Translation, Temple Grandin writes of driving two indoor cats crazy by flicking a laser pointer around the room. They wouldn't stop stalking and pouncing on this ungraspable dot of light—their dopamine system pumping. She writes that no wild cat would indulge in such useless behavior: "A cat wants to catch the mouse, not chase it in circles forever." She says "mindless chasing" makes an animal less likely to meet its real needs "because it short-circuits intelligent stalking behavior." As we chase after flickering bits of information, it's a salutary warning.

  • The Google Wave chatting tool is too complicated for its own good.
  • Chatting on Wave is like talking to an overcurious mind reader.
  • This behavior is so corrosive to normal conversation that you'd think it was some kind of bug. In fact, it's a feature—indeed, it's one of the Wave team's proudest accomplishments.

  • Even Thomas Friedman would be aghast at some of Jarvis’s cheesy sound-bites
  • What does that actually mean?
  • In Jarvis’s universe, all the good things are technologically determined and all the bad things are socially determined
  • ...7 more annotations...
  • Jarvis never broaches such subtleties. His is a simple world:
  • why not consider the possibility that the incumbents may be using the same tools, Jarvis’s revered technologies, to tell us what to think, and far more effectively than before? Internet shelf space may be infinite, but human attention is not. Cheap self-publishing marginally improves one’s chances of being heard, but nothing about this new decentralized public sphere suggests that old power structures—provided they are smart and willing to survive—will not be able to use it to their benefit
  • Jarvis 1.0 was all about celebrating Google, but Jarvis 2.0 has new friends in Facebook and Twitter. (An Internet intellectual always keeps up.) Jarvis 1.0 wrote that “Google’s moral of universal empowerment is the sometimes-forgotten ideal of democracy,” and argued that the company “provides the infrastructure for a culture of choice,” while its “algorithms and its business model work because Google trusts us.” Jarvis 2.0 claims that “by sharing publicly, we people challenge Google’s machines and reclaim our authority on the internet from algorithms.”
  • Jarvis has another reference point, another sacred telos: the equally grand and equally inexorable march of the Internet, which in his view is a technology that generates its own norms, its own laws, its own people. (He likes to speak of “us, people of the Net.”) For the Technology Man, the Internet is the glue that holds our globalized world together and the divine numen that fills it with meaning. If you thought that ethnocentrism was bad, brace yourself for Internet-centrism
  • Why worry about the growing dominance of such digitalism? The reason should be obvious. As Internet-driven explanations crowd out everything else, our entire vocabulary is being re-defined. Collaboration is re-interpreted through the prism of Wikipedia; communication, through the prism of social networking; democratic participation, through the prism of crowd-sourcing; cosmopolitanism, through the prism of reading the blogs of exotic “others”; political upheaval, through the prism of the so-called Twitter revolutions. Even the persecution of dissidents is now seen as an extension of online censorship (rather than the other way around). A recent headline on the blog of the Harvard-based Herdictproject—it tracks Internet censorship worldwide—announces that, in Mexico and Morocco, “Online Censorship Goes Offline.” Were activists and dissidents never harassed before Twitter and Facebook?
  • Most Internet intellectuals simply choose a random point in the distant past—the honor almost invariably goes to the invention of the printing press—and proceed to draw a straight line from Gutenberg to Zuckerberg, as if the Counter-Reformation, the Thirty Years’ War, the Reign of Terror, two world wars—and everything else—never happened.
  • even their iPad is of interest to them only as a “platform”—another buzzword of the incurious—and not as an artifact that is assembled in dubious conditions somewhere in East Asian workshops so as to produce cultic devotion in its more fortunate owners. This lack of elementary intellectual curiosity is the defining feature of the Internet intellectual. History, after all, is about details, but no Internet intellectual wants to be accused of thinking small. And so they think big—sloppily, ignorantly, pretentiously, and without the slightest appreciation of the difference between critical thought and market propaganda.

  • I don’t think we should at all be talking about “putting courses online.” What we are really faced with is coming up with some quick alternative modes for students to complete course work without showing up on campus. This does not call for apps and vendor solutions, but what the best teachers always do- improvise, change up on the fly when things change.
  • my suggestion an strategy would be… do as little as possible online. Use online for communicating, caring, attending to people’s needs, but not really for being the “course”. Flip that stuff outside.
  • This is why I cringe when what I seem to hear is “Zoom! Zoom! Can we have 30 students in zoom?” Everything you try to do online is going to call on for jumping unfair levels of barriers- access, technology, experience. I’d say recast your activities in ways students can do as much without going online- reading, writing, thinking, practicing, doing stuff away from the screen.
  • ...4 more annotations...
  • The most important things to me are quickly establishing, and having backup modes, for students to be in touch with you, and you with them. As individuals. It might be direct messaging, email, texting. It could be but need not be something Slack-like. I’d really go simplest (email)
  • Get going with web annotation tools
  • We need not have just talking sessions for use of video. Think about drop in hours with Whereby (the new appear.in) – it lacks a need for logins and downloads, and works on mobile.
  • This experiment is going to.. well I bet, go bad in a lot of ways. I don’t know what we can expect of un-experienced teachers and unprepared students, who on top of all the concerns they carry and we rarely see, now have to ponder where they might live and sustain income to live on. It will be interesting… but it need not be awful nor a disaster, if we go about as sharing in the situation.

  • The Green Zone: Underappreciated Workhorses Starting with the green zone in the lower left, we have readings with text and images. These types of assignments may not seem exciting, but sharing readings with students in a consistent and organized way provides your online course with a very practical, solid foundation. Email and discussion boards also belong in this quadrant.  Online instructors have been using these three tools—file sharing (for readings and such), email, and discussion boards—for decades. And while that might make them sound boring, you can create some fantastic instructional experiences with just these three tools. 
  • The Blue Zone: Practical Immediacy Moving over to the lower right, we have low-bandwidth tools that can add immediacy to student interactions. If you’ve used Microsoft Office 365 or Google Drive, you’re probably already familiar with some of the features and benefits of collaborative document editors. These tools allow multiple people to edit and comment on the same document, spreadsheet, or presentation slides. Depending on how you structure your assignments, students could collaborate over an extended period of time, or they could go online at the exact same time and write and edit each other’s work simultaneously.  When it comes to group chat/messaging, there are lots of free apps that can be useful in an educational setting. Slack and GroupMe are two popular examples. These mobile-friendly apps allow students to post text-based messages and images without requiring anyone in the group (including you!) to share their phone numbers. These tools allow students to communicate quickly and easily without scheduling an entire day around a formal video conference.
  • Screencasting adds a human element to online courses because your voice creates a sense of presence that plain text can’t. 
  • ...4 more annotations...
  • Students are more likely to watch a series of shorter videos than a single, longer video, which is why I recommend instructors try to divide long screencasts into five-to-ten minute segments (whenever possible)
  • asynchronous discussion with audio and video. If you’re not familiar with this concept, I’m referring to discussion tools that allow students to respond with audio and video instead of just text. One tool that’s been a leader for a long time in this multimedia discussion space is VoiceThread. While VoiceThread’s defining feature is its user-friendly approach to audio-based commenting, it can also be used to create narrated presentations with PowerPoints slides, images, and video. If you find yourself overwhelmed by the interface of a traditional screencasting tool, VoiceThread is worth exploring as a simpler way of recording online lectures and fostering discussions that go beyond plain text
  • tools that require both high bandwidth and high immediacy, and the best examples of this are videoconferencing tools like Zoom or Skype.  Videoconferencing is a great way to engage with students when they truly need to see and hear each other in real time. It can also be useful for online office hours, since it’s easier to feel connected and avoid misunderstandings when you have the benefit of tone of voice, facial expressions, and body language.  Unfortunately, videoconferencing is one of the most inflexible and bandwidth-intensive activities we can ask our students to do. Before you rely on it too heavily, look at the other quadrants and ask yourself if there’s any other way to accomplish your learning objectives without it. 
  • None of this is to say that videoconferencing is inherently bad or that it has no place in an online course. It’s simply a reminder that seemingly small (and sometimes unconscious) choices about the technologies we use can have a big impact on how inclusive and effective our teaching is.

How to Turn Your Syllabus into an Infographic - The Visual Communication Guy - 0 views

syllabi education design infographic access

shared by Ed Webb on 13 Jul 20 - Cached
  • If you’re ever going to turn a syllabus into an infographic, you must, MUST reduce the amount of text you are using. There are, of course, important things you’ll want and must include, but you can’t think of this document as ten pages of paragraphs. Strip down to only the essential information, with a bit of added info where you  think some flare or excitement is needed. Remember: your students are smart people. They can understand documents quickly without a bunch of extra fluff, so remove all the unnecessary stuff.
  • Once you’ve determined the sections, it’s easier to think about what relates to what and how you might organize your syllabus in a way that makes sense for your students.
  • try drawing it out on sketch paper first. While this will seem like an annoying task for most people, trust me when I say that it will save you a lot of time in the long run
  • ...5 more annotations...
  • If there is anything on your syllabus that can be quantified (like percentages for grades or assignments), consider making bar graphs or pie charts to visually represent it. This is helpful, too, so students can visually understand, very quickly, how much weight is given to each project.
  • Remember to only use pictures that you either created yourself (own the copyright) or that you found through creative commons or public domain websites. Don’t use ugly clipart or images that you don’t have permission to use. A great place to find free icons? Flaticon.com.
  • Remember to reduce as much text as possible and supplement what you write with an image. Consider using the images of your required textbooks, for example, and use icons and graphics that relate to each section.
  • Adobe InDesign
  • Don’t get so caught up in designing a cool infographic about your course that you forget to include information about accessibility, Title IX, academic dishonesty, and other related information. I might recommend not going too fancy on the institution-wide policies. You might still keep that in paragraph form, just so that there is no way to misinterpret what your institution wants you to say.

  • the virus will be far more present in far more places when school starts in August than it was when most schools shut down in March
  • I am among the crowd who both believes that online learning can be done quite well, and that there is something irreplaceable about the experiences of face-to-face learning, when that learning is happening under reasonable conditions that is. These are not reasonable conditions. Do not get me wrong. This is a loss. The experience of community is not the same at a distance or over the internet. It is not necessarily entirely absent, but it is not as present.

  • One of the most interesting changes that I saw in terms of online learning was the use of WhatsApp, a text and voice messaging app that is very popular in South Africa. Through the app’s group chat feature, instructors can moderate the discussion and students can leave voice notes, which gives them the ability to have their voices heard asynchronously
  • I’ve imagined a north–south dialogue. Now, due to COVID-19, it’s happening organically, and I’m in the process of reimagining the course I would have been teaching in Vancouver this summer as an online course. I need to factor in which apps to use, how to prepare for students who only have cellphones, and the reality that many students come from other countries to study at Emily Carr, and now they’ll be learning remotely. It’s fascinating that the forced global aspect of the classroom will influence the way I design the educational technology for my program
  • In the past, some educators might have been excited to tear everything apart and build it back up with a goal of helping students learn in a better way, but the institutions wouldn’t be able to support it. Not because they didn’t want to, but because it was difficult for them to do it. Now there’s an opportunity for institutions to let the reins go and encourage creative and new approaches. It’s scary, but it’s also inspiring for educators to have that freedom. The research is available, the interest is there, and the resources are open, so now is the time to make it happen
  • ...9 more annotations...
  • “What surprised me was the resurgence of many of the zombie ideas about online learning creeping into the discussions, such as the idea that online learning isn’t as personal, or that you can’t have interactivity, or that it just doesn’t work. And while it is true you need to change how you think about your course — you can’t just replicate what you used to do in the classroom — there’s an opportunity to evolve your teaching practices and create a better learning experience for your students.”
  • What’s happening now is going to reshape education for years, if not decades.
  • People want the old normal, not the new normal. We will, to some degree, get back to what we know and love, but it won’t ever look like it did before
  • “Like your physical buildings on campus, you also have a somewhat invisible set of resources called your educational technology. If you don’t understand it well and don’t treat it as important infrastructure, your ability to move online sustainably will be challenged. Sometimes institutions see eLearning as a project, not a strategy. Online learning isn’t a fly-by-the-seat-of-your-pants project; it has to be integrated into your academic plan and institutional strategy. I hope that COVID-19 underlined that for institutions.”
  • “We’ve known for over 30 years now that one-hour lectures are not a great way to teach: you can have a good one-hour session, but can you have 13 over a semester? It’s about cognitive load, and students can’t focus for more than 15 to 20 minutes at a time without being distracted. There’s room for synchronous discussion, but we can do it better. There’s a huge amount of research into online learning and what happens when students have access to online learning whenever they want it. And just like in real life, you have to know how to do both synchronous and asynchronous interactions well.”
  • We need to make space for the voices of communities who haven’t traditionally been heard: non-traditional learners, students who are food or housing insecure, students who are neurodivergent, students of colour, and Indigenous students. We must think of all these populations and the degree to which our educational system — our technology, our platforms — has not been built for them. We do a lot of work to make our methods accessible, but at the core, our systems, institutions, and platforms aren’t really built for — or by — those students
  • s challenging as it is, I’m seeing online pedagogy’s focus on equity and care resonating with many of those new to the medium
  • I’ve used really experimental styles over the past few years, but I won’t be doing that as much over the coming year because I shouldn’t. My classes are traditionally where students get to work with tools and platforms outside of the norm. If everyone moving online treats it that way, the cognitive load on the students will be absolutely overwhelming. My right to flex my academic freedom regarding platforms should be superseded by care and consideration for my students’ cognitive loads across a program. Navigating different platforms and tools is hard and distracting.
  • “One of the most vital tools and resources that I’ve seen people using is their human capacities for compassion and patience — the degree to which faculty are stepping up and approaching their students from a place of care, and a place of genuine desire for students to feel a sense of hope, safety, and flexibility.”

This included PII, entire poems, “cryptographically-random identifiers” like Bitcoin addresses, passages from copyrighted scientific research papers, website addresses, and much more.
  • The researchers wrote that they spent $200 to create “over 10,000 unique examples” of training data, which they say is a total of “several megabytes” of training data. The researchers suggest that using this attack, with enough money, they could have extracted gigabytes of training data.
