      Is hydrogen sustainable? depends on the source. see this highlight.
  • While methods of hydrogen production that do not use fossil fuel would be more sustainable
  • The challenges facing the use of hydrogen in vehicles include production, storage, transport and distribution.
  • ...3 more annotations...
  • The hydrogen infrastructure consists mainly of industrial hydrogen pipeline transport and hydrogen-equipped filling stations like those found on a hydrogen highway. Hydrogen stations which are not situated near a hydrogen pipeline can obtain supply via hydrogen tanks, compressed hydrogen tube trailers, liquid hydrogen tank trucks or dedicated onsite production.
  • Hydrogen use would require the alteration of industry and transport on a scale never seen before in history. For example, according to GM, 70% of the U.S. population lives near a hydrogen-generating facility but has little access to hydrogen, despite its wide availability for commercial use.[64] The distribution of hydrogen fuel for vehicles throughout the U.S. would require new hydrogen stations that would cost, by some estimates approximately 20 billion dollars[65] and 4.6 billion in the EU.[66] Other estimates place the cost as high as half trillion dollars in the United States alone.[67]
  • Hydrogen fuel does not occur naturally on Earth and thus is not an energy source, but is an energy carrier. Currently it is most frequently made from methane or other fossil fuels. However, it can be produced from a wide range of sources (such as wind, solar, or nuclear) that are intermittent, too diffuse or too cumbersome to directly propel vehicles. Integrated wind-to-hydrogen plants, using electrolysis of water, are exploring technologies to deliver costs low enough, and quantities great enough, to compete with traditional energy sources.[2]

    "Joyce Valenza Ph.D On the librarian: What's the point . . ? The Twitter conversation April 30, 2009 @karlfisch: What's the point of having a media specialist if they aren't specialists in the media forms of the day? I was nearly finished copying and pasting, figuring out how best to post Tuesday's Twitter conversation, when I discovered that Karl Fisch (@karlfisch), who kinda started it all, already took care of that. (You likely know of Karl's very popular and provocative videos.) I am still not sure how best to frame this conversation on the place of the information/media specialist in today's school. What is clear is that a lot of smart people--people who are out there teaching, speaking, moving, and shaking--are disappointed in what they see when they see school librarians. Either we have a perception problem or we need to do some serious retooling. I'd say we have to deal with both. In a hurry. Being an information (or media) specialist today means being an expert in how information and media flow TODAY! It is about knowing how information and media are created and communicated. How to evalute, synthesize, and ethically use information and media in all their varied forms. It is about being able to communicate knowlege in new ways for new audiences using powerful new information and communication tools. Forgive me if it hurts. In my mind, if you are not an expert in new information and communication tools, you are NOT a media specialist for today. Tuesday's conversation happened in the open, on Twitter. We need to be aware that these conversations are happening where we cannot hear them--at conferences, at Board and cabinet meetings. We also need to make sure that our voices are heard and that we hear the voices of others in places like Twitter, where so many educational leaders and thinkers are chatting about us and many other things. I've selected the remarks that resonated loudest for me. (I've shuffled a bit, but you can visit Karl'

  • Social relations—not simply physical space—structure the social worlds of youth.

      A critical conclusion to be realized that can inform our assumptions as educators.
  • When teens are involved in friendship-driven practices, online and offline are not separate worlds—they are simply different settings in which to gather with friends and peers
  • these dynamics reinforce existing friendship patterns as well as constitute new kinds of social arrangements.
  • ...43 more annotations...
  • Homophily describes the likelihood that people connect to others who share their interests and identity.
  • One survey of Israeli teens suggests that those who develop friendships online tend toward less homogenous connections than teens who do not build such connections
  • Teens frequently use social media as additional channels of communication to get to know classmates and turn acquaintances into friendships.
  • Some teens—especially marginalized and ostracized ones—often relish the opportunity to find connections beyond their schools. Teens who are driven by specific interests that may not be supported by their schools, such as those described in the Creative Production and Gaming chapters, often build relationships with others online through shared practice.
  • there are plenty of teens who relish the opportunity to make new connections through social media, this practice is heavily stigmatized
  • the public myths about online “predators” do not reflect the actual realities of sexual solicitation and risky online behavior (Wolak et al. 2008). Not only do unfounded fears limit teenagers unnecessarily, they also obscure preventable problematic behavior
  • As she described her typical session on Photobucket, it became clear that a shared understanding of friendship and romance was being constructed by her and other Photobucket users:
  • The fact that they draw from all of these sources suggests that youth’s friendship maintenance is in tune with a discourse of love and friendship that is being widely displayed and (re)circulated.
  • “It’s like have you noticed that you may have someone in your Top 8 but you’re not in theirs and you kinda think to yourself that you’re not as important to that person as they are to you . . . and oh, to be in the coveted number-one spot!”
  • Taking someone off your Top 8 is your new passive-aggressive power play when someone pisses you off.
  • Top Friends are persistent, publicly displayed, and easily alterable. This makes it difficult for teens to avoid the issue or make excuses such as “I forgot.” When pressured to include someone, teens often oblige or attempt to ward off this interaction by listing those who list them
  • Other teens avoid this struggle by listing only bands or family members. While teens may get jealous if other peers are listed, family members are exempt from the comparative urge.
  • to avoid social drama with her friends:
  • The Top Friends feature is a good example of how structural aspects of software can force articulations that do not map well to how offline social behavior works.
  • teens have developed a variety of social norms to govern what is and is not appropriate
  • The problem with explicit ranking, however, is that it creates or accentuates hierarchies where they did not exist offline, or were deliberately and strategically ambiguous, thus forcing a new set of social-status negotiations. The give-and-take over these forms of social ranking is an example of how social norms are being negotiated in tandem with the adoption of new technologies, and how peers give ongoing feedback to one another as part of these struggles to develop new cultural standards.
  • While teen dramas are only one component of friendship, they are often made extremely visible by social media. The persistent and networked qualities of social media alter the ways that these dramas play out in teen life. For this reason, it is important to pay special attention to the role that social media play in the negotiation of teen status.
  • primarily a continuation of broader dramas.
  • social media amplify dramas because they extend social worlds beyond the school.
  • Gossip and rumors have played a role in teen struggles for status and attention since well before social media entered the scene
  • social media certainly alter the efficiency and potential scale of interactions. Because of this, there is greater potential for gossip to spread much further and at a faster pace, making social media a culprit in teen drama. While teen gossip predates the Internet, some teens blame the technologies for their roles in making gossip easier and more viral
  • That’s what happened with me and my friends. We got into a lot of drama with it and I was like, anyone can write anything. It can be fact, fiction. Most people, what they read they believe. Even if it’s not true (C.J. Pascoe, Living Digital).
  • finds the News Feed useful “because it helps you to see who’s keeping track of who and who’s talking to who.” She enjoys knowing when two people break up so that she knows why someone is upset or when she should reach out to offer support. Knowing this information also prevents awkward conversations that might reference the new ex. While she loves the ability to keep up with the lives of her peers, she also realizes that this means that “everybody knows your business.”
  • Some teens find the News Feed annoying or irrelevant. Gadil, an Indian 16-year-old from Los Angeles, thinks that it is impersonal while others think it is downright creepy. For Tara, a Vietnamese 16-year-old from Michigan, the News Feed takes what was public and makes it more public: “Facebook’s already public. I think it makes it way too like stalker-ish.” Her 18-year-old sister, Lila, concurs and points out that it gets “rumors going faster.” Kat, a white 14-year-old from Salem, Massachusetts, uses Facebook’s privacy settings to hide stories from the News Feed for the sake of appearances.
  • While gossip is fairly universal among teens, the rumors that are spread can be quite hurtful. Some of this escalates to the level of bullying. We are unable to assess whether or not bullying is on the rise because of social media. Other scholars have found that most teens do not experience Internet-driven harassment (Wolak, Mitchell, and Finkelhor 2007). Those who do may not fit the traditional profile of those who experience school-based bullying (Ybarra, Diener-West, and Leaf 2007), but harassment, both mediated and unmediated, is linked to a myriad of psychosocial issues that includes substance use and school problems (Hinduja and Patchin 2008; Ybarra et al. 2007).
  • Measuring “cyberbullying” or Internet harassment is difficult, in part because both scholars and teens struggle to define it. The teens we interviewed spoke regularly of “drama” or “gossip” or “rumors,” but few used the language of “bullying” or “harassment” unless we introduced these terms. When Sasha, a white 16-year-old from Michigan, was asked specifically about whether or not rumors were bullying, she said: I don’t know, people at school, they don’t realize when they are bullying a lot of the time nowadays because it’s not so much physical anymore. It’s more like you think you’re joking around with someone in school but it’s really hurting them. Like you think it’s a funny inside joke between you two, but it’s really hurtful to them, and you can’t realize it anymore. Sasha, like many of the teens we interviewed, saw rumors as hurtful, but she was not sure if they were bullying. Some teens saw bullying as being about physical harm; others saw it as premeditated, intentionally malicious, and sustained in nature. While all acknowledged that it could take place online, the teens we interviewed thought that most bullying took place offline, even if they talked about how drama was happening online.
  • it did not matter whether it was online or offline; the result was still the same. In handling this, she did not get offline, but she did switch schools and friend groups.
  • Technology provides more channels through which youth can potentially bully one another. That said, most teens we interviewed who discussed being bullied did not focus on the use of technology and did not believe that technology is a significant factor in bullying.
  • They did, though, see rumors, drama, and gossip as pervasive. The distinction may be more connected with language and conception than with practice. Bianca, a white 16-year-old from Michigan, sees drama as being fueled by her peers’ desire to get attention and have something to talk about. She thinks the reason that people create drama is boredom. While drama can be hurtful, many teens see it simply as a part of everyday social life.
  • Although some drama may start out of boredom or entertainment, it is situated in a context where negotiating social relations and school hierarchies is part of everyday life. Teens are dealing daily with sociability and related tensions.
  • Tara thinks that it emerges because some teens do not know how to best negotiate their feelings and the feelings of others.
  • Teens can use the ability to publicly validate one another on social network sites to reaffirm a friendship.
  • So, while drama is common, teens actually spend much more time and effort trying to preserve harmony, reassure friends, and reaffirm relationships. This spirit of reciprocity is common across a wide range of peer-based learning environments we have observed.
  • From this perspective, commenting is not as much about being nice as it is about relying on reciprocity for self-gain
  • That makes them feel like they’re popular, that they’re getting comments all the time by different people, even people that they don’t know. So it makes them feel popular in a way (Rural and Urban Youth).
  • Gossip, drama, bullying, and posing are unavoidable side effects of teens’ everyday negotiations over friendship and peer status. What takes place in this realm resembles much of what took place even before the Internet, but certain features of social media alter the dynamics around these processes. The public, persistent, searchable, and spreadable nature of mediated information affects the way rumors flow and how dramas play out. The explicitness surrounding the display of relationships and online communication can heighten the social stakes and intensity of status negotiation. The scale of this varies, but those who experience mediated harassment are certainly scarred by the process. Further, the ethic of reciprocity embedded in networked publics supports the development of friendships and shared norms, but it also plays into pressures toward conformity and participation in local, school-based peer networks. While there is a dark side to what takes place, teens still relish the friendship opportunities that social media provide.
  • While social warfare and drama do exist, the value of social media rests in their ability to strengthen connections. Teens leverage social media for a variety of practices that are familiar elements of teen life: gossiping, flirting, joking around, and hanging out. Although the underlying practices are quite familiar, the networked, public nature of online communication does inflect these practices in new ways.
  • Adults’ efforts to regulate youth access to MySpace are the latest example of how adults are working to hold on to authority over teen socialization in the face of a gradual erosion of parental influence during the teen years.
  • learning how to manage the unique affordances of networked sociality can help teens navigate future collegiate and professional spheres where mediated interactions are assumed.
  • articulating those friendships online means that they become subject to public scrutiny in new ways;
  • This makes lessons about social life (both the failures and successes) more consequential and persistent
  • make these dynamics visible in a more persistent and accessible public arena.
  • co-constructing new sets of social norms together with their peers and the efforts of technology developers. The dynamics of social reciprocity and negotiations over popularity and status are all being supported by participation in publics of the networked variety as formative influences in teen life. While we see no indication that social media are changing the fundamental nature of these friendship practices, we do see differences in the intensity of engagement among peers, and conversely, in the relative alienation of parents and teachers from these social worlds.

CHRISTIE HEMM KLOK/WIRED SO YOU'RE A parent, thinking about sending your 7-year-old to this rogue startup of a school you heard about from your friend's neighbor's sister. It's prospective parent information day, and you make the trek to San Francisco's South of Market neighborhood. You walk up to the second floor of the school, file into a glass-walled conference room overlooking a classroom, and take a seat alongside dozens of other parents who, like you, feel that public schools-with their endless bubble-filled tests, 38-kid classrooms, and antiquated approach to learning-just aren't cutting it. At the same time, you're thinking: this school is kind of weird. On one side of the glass is a cheery little scene, with two teachers leading two different middle school lessons on opposite ends of the room. But on the other side is something altogether unusual: an airy and open office with vaulted ceilings, sunlight streaming onto low-slung couches, and rows of hoodie-wearing employees typing away on their computers while munching on free snacks from the kitchen. And while you can't quite be sure, you think that might be a robot on wheels roaming about. Then there's the guy who's standing at the front of the conference room, the school's founder. Dressed in the San Francisco standard issue t-shirt and jeans, he's unlike any school administrator you've ever met. But the more he talks about how this school uses technology to enhance and individualize education, the more you start to like what he has to say. And so, if you are truly fed up with the school stat

  • Students should never use information in Wikipedia (or any other online encyclopedia) for formal purposes (such as school essays) until they have verified and evaluated the information based on external sources. For this reason, Wikipedia, like any encyclopedia, is a great starting place for research but not always a great ending place.
  • It is possible for a given Wikipedia article to be biased, outdated, or factually incorrect. This is true of any resource. One should always double-check the accuracy of important facts, regardless of the source. In general, popular Wikipedia articles are more accurate than ones that receive little traffic, because they are read more often and therefore any errors are corrected in a more timely fashion. Wikipedia articles may also suffer from issues such as Western bias, but hopefully this will also improve with time. For more information

  • It is for this reason that readers must be particularly diligent in verifying Wikipedia against its external sources, as discussed above. It is also a good idea, if you feel uncomfortable about an article, to check its history for recent "bad-faith" edits.

  • Wikipedia can be an excellent starting place for further research.
  • Students can compare information in Wikipedia with information in other encyclopedias or books in the library. As a general rule, contributors to Wikipedia are encouraged to cite their sources, but, of course, not all do. For the sake of verifiability, it is advisable to cite an article that has listed its sources.

  • The Method of Loci (plural of Latin locus for place or location), also called the memory palace, is a mnemonic device introduced in ancient Roman and Greek rhetorical treatises (in the anonymous Rhetorica ad Herennium, Cicero's De Oratore, and Quintilian's Institutio oratoria). The items to be remembered in this mnemonic system are mentally associated with specific physical locations.[1] It relies on memorized spatial relationships to establish, order and recollect memorial content. The term is most often found in specialised works on psychology, neurobiology and memory, though it was used in the same general way at least as early as the first half of the nineteenth century in works on rhetoric, logic and philosophy.[2]

  • If our ideas seem smaller nowadays, it’s not because we are dumber than our forebears but because we just don’t care as much about ideas as they did. In effect, we are living in an increasingly post-idea world — a world in which big, thought-provoking ideas that can’t instantly be monetized are of so little intrinsic value that fewer people are generating them and fewer outlets are disseminating them, the Internet notwithstanding. Bold ideas are almost passé.
  • we live in a post-Enlightenment age in which rationality, science, evidence, logical argument and debate have lost the battle in many sectors, and perhaps even in society generally, to superstition, faith, opinion and orthodoxy. While we continue to make giant technological advances, we may be the first generation to have turned back the epochal clock — to have gone backward intellectually from advanced modes of thinking into old modes of belief.
  • Post-Enlightenment refers to a style of thinking that no longer deploys the techniques of rational thought. Post-idea refers to thinking that is no longer done, regardless of the style.

  • In the past, we collected information not simply to know things. That was only the beginning. We also collected information to convert it into something larger than facts and ultimately more useful — into ideas that made sense of the information. We sought not just to apprehend the world but to truly comprehend it, which is the primary function of ideas. Great ideas explain the world and one another to us.
  • These ideas enabled us to get our minds around our existence and attempt to answer the big, daunting questions of our lives.
  • But if information was once grist for ideas, over the last decade it has become competition for them.
  • In effect, we are living within the nimbus of an informational Gresham’s law in which trivial information pushes out significant information, but it is also an ideational Gresham’s law in which information, trivial or not, pushes out ideas.
  • We prefer knowing to thinking because knowing has more immediate value. It keeps us in the loop
  • For one thing, social networking sites are the primary form of communication among young people, and they are supplanting print, which is where ideas have typically gestated. For another, social networking sites engender habits of mind that are inimical to the kind of deliberate discourse that gives rise to ideas.
  • Indeed, the gab of social networking tends to shrink one’s universe to oneself and one’s friends, while thoughts organized in words, whether online or on the page, enlarge one’s focus.
  • But because they are scientists and empiricists rather than generalists in the humanities, the place from which ideas were customarily popularized, they suffer a double whammy: not only the whammy against ideas generally but the whammy against science, which is typically regarded in the media as mystifying at best, incomprehensible at worst. A generation ago, these men would have made their way into popular magazines and onto television screens.

  • Uncertainty is an inherent part of new ideas, and it’s also something that most people would do almost anything to avoid. People’s partiality toward certainty biases them against creative ideas and can interfere with their ability to even recognize creative ideas.
  • Unfortunately, the place where our first creative ideas go to die is the place that should be most open to them—school. Studies show that teachers overwhelmingly discriminate against creative students, favoring their satisfier classmates who more readily follow directions and do what they’re told.
  • It’s ironic that even as children are taught the accomplishments of the world’s most innovative minds, their own creativity is being squelched.
  • All of this negativity isn’t easy to digest, and social rejection can be painful in some of the same ways physical pain hurts. But there is a glimmer of hope in all of this rejection. A Cornell study makes the case that social rejection is not actually bad for the creative process—and can even facilitate it.
  • Truly creative ideas take a very long time to be accepted. The better the idea, the longer it might take.
  • Most people agree that what distinguishes those who become famously creative is their resilience. While creativity at times is very rewarding, it is not about happiness. Staw says a successful creative person is someone “who can survive conformity pressures and be impervious to social pressure.”

  • Blended learning, with its mix of technology and traditional face-to-face instruction, is a great approach. Blended learning combines classroom learning with online learning, in which students can, in part, control the time, pace, and place of their learning. I advocate a teacher-designed blended learning model, in which teachers determine the combination that's right for them and their students.
  • Tip 1: Think big, but start small.
  • Tip 2: Patience is a virtue when trying something new.
  • ...17 more annotations...
  • Tip 3: Technology shouldn't be just a frill.
  • Tip 4: Weaving media together makes them stronger.
  • Tip 5: Students need to know where they can get online.
  • Student-centered classrooms are the goal of my teacher-designed blended learning model. Giving students control over the learning process requires that they know how to communicate, collaborate, and solve problems in groups, pairs, and individually. This work can be messy, loud, and disorganized, but in the end, the learning is much more meaningful.
  • Then I found Collaborize Classroom, a free, dynamic discussion platform. I used it to replace many of my pen-and-paper homework assignments with vibrant online debates, discussions, writing assignments, and collaborative group work.
  • Remember that mistakes lead to learning. The best resources I've designed and the most effective strategies I've developed were all born from and refined through mistakes.
  • I anticipated that students might hit some bumps as they navigated their first TED-Ed lesson, so I set up a TodaysMeet back channel so students could ask questions, make comments, and access a support network while going through the online lesson. A back-channel tool makes it possible for people to have a real-time conversation online while a live presentation or real-time discussion is taking place.
  • I asked students to reference specific details to support their assertions, as did one student who commented on the town's poverty by noting that the local doctor often took potatoes as payment for his work. She also showed how the characters nevertheless reflected the country's "cautious optimism" about its future: That same doctor was still able to support himself, she pointed out, and he enjoyed his work. Students posted their responses, complimenting strong points made, asking questions, and offering alternative perspectives.
  • I asked students to analyze examples of strong discussion posts and revise weaker posts. I also realized that I needed to embed directions into our discussion topics to remind students to respond to the questions and engage with their peers. I started requiring them to thoughtfully reply to at least two classmates' posts, in addition to posting their own response to the topic.
  • It's crucial for students to see that the work they do in the online space drives the work they do in the classroom so they recognize the value of the online conversations.
  • For example, during the To Kill a Mockingbird unit, we researched and discussed the death penalty in preparation for writing an argument essay. The students debated online such issues as cost, morality, and racial inequality and then delved into these topics more deeply face-to-face in class.
  • In the classroom, the teacher might give small groups various topics to research. Then he or she could ask students to go online to research and discuss their topic on a shared Google Doc and create a presentation using Glogster, Prezi, or Google Presentation Maker.
  • When we read Romeo and Juliet, I use this strategy to encourage students to research such topics as the monarchy, entertainment, and gender roles in Elizabethan England so they have a better understanding of the historical context in which Shakespeare wrote. Back in the classroom, each group then presents its findings through an oral presentation.
  • Compared with traditional in-class group work, which typically yields a disappointing finished product, online work provides the time necessary for students to complete quality work together.
  • Some teachers think that incorporating online work means they have to be available 24 hours a day. This is not the case. When students are connected online, they have a network of peers they can reach out to for support, and they begin to see one another as valuable resources in their class community.
  • I've embedded a Google map in my website that has pins dropped in all the locations on our campus and in our community where there are computers with public access to the Internet.
  • I even wrote the local computer recycling center to request a computer for my class.

  • The central paradox of the machines that have made our lives so much brighter, quicker, longer and healthier is that they cannot teach us how to make the best use of them; the information revolution came without an instruction manual.
  • The only way to do justice to our onscreen lives is by summoning exactly the emotional and moral clarity that can’t be found on any screen.
  • MAYBE that’s why more and more people I know, even if they have no religious commitment, seem to be turning to yoga, or meditation, or tai chi; these aren’t New Age fads so much as ways to connect with what could be called the wisdom of old age.

  • Other friends try to go on long walks every Sunday, or to “forget” their cellphones at home. A series of tests in recent years has shown, Mr. Carr points out, that after spending time in quiet rural settings, subjects “exhibit greater attentiveness, stronger memory and generally improved cognition. Their brains become both calmer and sharper.”
  • I noticed that all their talk was of sailing — or riding or bridge: anything that would allow them to get out of radio contact for a few hours.
  • empathy, as well as deep thought, depends (as neuroscientists like Antonio Damasio have found) on neural processes that are “inherently slow.” The very ones our high-speed lives have little time for.
  • I’ve yet to use a cellphone and I’ve never Tweeted or entered Facebook. I try not to go online till my day’s writing is finished, and I moved from Manhattan to rural Japan in part so I could more easily survive for long stretches entirely on foot, and every trip to the movies would be an event.
  • Nothing makes me feel better — calmer, clearer and happier — than being in one place, absorbed in a book, a conversation, a piece of music.
  • For more than 20 years, therefore, I’ve been going several times a year — often for no longer than three days — to a Benedictine hermitage, 40 minutes down the road, as it happens, from the Post Ranch Inn. I don’t attend services when I’m there, and I’ve never meditated, there or anywhere; I just take walks and read and lose myself in the stillness, recalling that it’s only by stepping briefly away from my wife and bosses and friends that I’ll have anything useful to bring to them.

  • Like the slur "anchor baby" itself, each of these claims is a fallacy. Far from "anchoring" their parents to US soil, many children born to undocumented immigrants are seeing them be deported. And for all the rhetoric spewed by the right about the need for tough new legislation to combat the immigrant "invasion," laws governing immigration to the United States have gotten more restrictive in the past fifteen years. Today, a citizen must be 21 in order to sponsor the green card application of a parent or an immediate relative. The applicant must then show documentation proving that he or she has not been in the United States unlawfully for more than one year. Barring such proof—the primary obstacle most immigrants face—the parent must return to the country of origin for ten years before being allowed to lawfully re-enter the United States and resume the application process. This is commonly referred to as the "touchback rule," explains María Blanco, director of the Earl Warren Institute at the UC, Berkeley, School of Law, and it is among the most insurmountable restrictions placed on the legal naturalization process in the name of "immigration reform" passed in 1996.

MOOC credentials education higher education

shared by Tracy Tuten on 09 Aug 12 - Cached
  • Is there a model out there, or an institution/student mix that could effectively utilize MOOCs in such a way as to get around this flaw? It’s hard to tell. Recent articles on Inside Higher Ed have suggested that distance education providers (like the University of Maryland’s University College – UMUC) may opt to certify the MOOCs that come out of these elite schools and bake them into their own online programs. Others suggest that MOOCs could be certified by other schools and embedded in prior learning portfolios.
  • The fatal flaw that I referred to earlier is pretty apparent:  the very notions of "mass, open" and selectivity just don’t lend themselves to a workable model that benefits both institutions and students. Our higher education system needs MOOCs to provide credentials in order for students to find it worthwhile to invest the effort, yet colleges can’t afford to provide MOOC credentials without sacrificing prestige, giving up control of the quality of the students who take their courses and running the risk of eventually diluting the value of their education brand in the eyes of the labor market.
  • In other words, as economists tell us, students themselves are an important input to education. The fact that no school uses a lottery system to determine who gets in means that determining who gets in matters a great deal to these schools, because it helps them control quality and head off the adverse effects of unqualified students either dropping out or performing poorly in career positions. For individual institutions, obtaining high quality inputs works to optimize the school’s objective function, which is maximizing prestige.

  • We also know that there are plenty of low- to no-cost learning options available to people on a daily basis, from books on nearly every academic topic at the local library and on-the-job experience, to the television programming on the National Geographic, History and Discovery channels. If learning can and does take place everywhere, there has to be a specific reason that people would be willing to spend tens of thousands of dollars and several years of their life to get it from one particular source like a college. There is, of course, and again it’s the credential, because no matter how many years I spend diligently tuned to the History Channel, I’m simply not going to get a job as a high-school history teacher with “television watching” as the core of my resume, even if I both learned and retained far more information than I ever could have in a series of college history classes.

When the 'A' in U.C.L.A. Stands for 'Achievement' - Campaign Spotlight - NYTimes.com - 0 views

  • The campaign, now getting under way, is for the University of California, Los Angeles. The campaign proclaims that U.C.L.A. is the home of “the optimists,” people who are risk-takers, rule-breakers and game-changers.
  • The campaign is the first for U.C.L.A. from an agency named 160 Over 90, which is based in Philadelphia and recently opened an office in Newport Beach, Calif.
  • That work underscores the growing presence of universities and colleges as advertisers in the media. Their goals include selling themselves to prospective students and the parents of those students, seeking donations from alumni, recruiting faculty members and improving their standings in various surveys.
  • ...7 more annotations...
  • The agency has also created ads for institutions of higher learning like Michigan State University, Loyola University Maryland and the University of Dayton.
  • The campaign has a section devoted to it on the U.C.L.A. Web site, ucla.edu/optimists, and is getting shout-outs on the U.C.L.A. fan page on Facebook and on the U.C.L.A. Twitter feed, where those who send messages are asked to use the hashtag #optimists.
  • The U.C.L.A. campaign has a small budget, estimated at less than $500,000, for a couple of reasons. One is that much of the campaign is appearing online; there is also print advertising, in newspapers.
  • The video clip can also be watched on YouTube.
  • The new campaign is meant to celebrate “the optimism that abounds on our campus,” she adds, “even in challenging times,” and shine a spotlight on “the dynamism and vitality” as well as the history and legacy of the university.
  • The way to do that, Ms. Turteltaub says, is to focus on “the icons” from U.C.L.A. “who made their mark in whatever fields they choose” and describe their “accomplishment, success, barrier-breaking.”
  • “This is the place that gives you the opportunity to be a game-changer,” Ms. Turteltaub says, “and you’ll choose the game.”

  • So why do I use Diigo?   I like its ability to enhance my bookmarking with highlights and sticky notes, that are retained with the page when I go back to it. I like that you can highlight and publish easily from Diigo to you blog or an email, and a reference appears automatically along with the posting. I like the ability to create lists on specific topics that can be shared. I like the ability to create groups to pool resources for specific subjects. I recently joined a few Diigo groups and have had some very useful sites brought to my attention. I like that you can access and search the bookmarks anywhere by full-text and tags. I like to search for the most popular bookmarks on a particular subject. I like the different ways to share and aggregate information that  Diigo offers. I have set it up so that a list of my new bookmarks appears on this blog on a weekly basis but this is just one option. You can now choose to automatically The tool bar is easy to download and makes it easy to use and aspect of Diigo whenever you are on line.
  • Of course you can keep things private if you choose to but that is really defeating the purpose of Diigo in the first place. Diigo also began offering, on Sept 19th, a Diigo Education Account Facility. I haven’t investigated this yet but a post about it was put onto the SLAV Bright Ideas blog. It is worth looking at. From Diigo ‘The Diigo Educator Accounts offer a suite of features that makes it incredibly easy for teachers to get their entire class of students or their peers started on collaborative research using Diigo’s powerful web annotation and social bookmarking technology.’ For an educator account, you do have to apply and fill out how/why you want to use Diigo in your school.
