News: The Mobile Campus - Inside Higher Ed - 0 views

  • Powell’s experiment, however, demonstrates the current limitations of Abilene Christian’s mobile learning study. Because the experiment took place on such a small scale, the margins of error were sometimes as high as 13 points, making it impossible to render statistically significant findings.
  • Although the university plans to saturate the 4,000-student campus with iPhones and iPod Touches by the fourth year of the study (giving them out to each incoming class), even then it will be difficult to extract good data, said Perkins, the lead researcher. “We could do this study for 10 years, and then maybe we could talk about statistical significance,” he said. “That’s just simply a function of the sample size.” In order to generate data that would comment widely on the uses and effectiveness of mobile technology on campuses, Perkins added, the study would have to partner with other institutions.
  • Since not all the students could necessarily afford AT&T service plans for their iPhones, and U.S. tax law would not permit the university to subsidize service plans for its students, Abilene Christian offered students the alternative of an iPod Touch — a device that shares many of the iPhone’s functions, but requires a wireless network to support Web-surfing.

What we learned from 5 million books | Video on TED.com - 0 views

    • Barbara Lindsey
       
      From YouTube version of this talk: "[Google's digtized books] are very practical and extremely awesome." Erez Lieberman Aiden and Jean-Baptiste Michel from Harvard University use the 15 million books scanned and digitized by Google to show how a visual and quantitative analysis of text can provide insights about fields as diverse as lexicography, the evolution of grammar, collective memory, the adoption of technology, the pursuit of fame, censorship, and historical epidemiology.
  • ELA: There are more sobering notes among the n-grams. For instance, here's the trajectory of Marc Chagall, an artist born in 1887. And this looks like the normal trajectory of a famous person. He gets more and more and more famous, except if you look in German. If you look in German, you see something completely bizarre, something you pretty much never see, which is he becomes extremely famous and then all of a sudden plummets, going through a nadir between 1933 and 1945, before rebounding afterward. And of course, what we're seeing is the fact Marc Chagall was a Jewish artist in Nazi Germany. Now these signals are actually so strong that we don't need to know that someone was censored. We can actually figure it out using really basic signal processing. Here's a simple way to do it. Well, a reasonable expectation is that somebody's fame in a given period of time should be roughly the average of their fame before and their fame after. So that's sort of what we expect. And we compare that to the fame that we observe. And we just divide one by the other to produce something we call a suppression index. If the suppression index is very, very, very small, then you very well might be being suppressed. If it's very large, maybe you're benefiting from propaganda.
  • Now when Google digitizes a book, they put it into a really nice format. Now we've got the data, plus we have metadata. We have information about things like where was it published, who was the author, when was it published. And what we do is go through all of those records and exclude everything that's not the highest quality data. What we're left with is a collection of five million books, 500 billion words, a string of characters a thousand times longer than the human genome -- a text which, when written out, would stretch from here to the Moon and back 10 times over -- a veritable shard of our cultural genome.

  • we're going to release statistics about the books. So take for instance "A gleam of happiness." It's four words; we call that a four-gram. We're going to tell you how many times a particular four-gram appeared in books in 1801, 1802, 1803, all the way up to 2008. That gives us a time series of how frequently this particular sentence was used over time. We do that for all the words and phrases that appear in those books, and that gives us a big table of two billion lines that tell us about the way culture has been changing.
  • You might also want to have a look at this particular n-gram, and that's to tell Nietzsche that God is not dead, although you might agree that he might need a better publicist.
  • JM: Now you can actually look at the distribution of suppression indexes over whole populations. So for instance, here -- this suppression index is for 5,000 people picked in English books where there's no known suppression -- it would be like this, basically tightly centered on one. What you expect is basically what you observe. This is distribution as seen in Germany -- very different, it's shifted to the left. People talked about it twice less as it should have been. But much more importantly, the distribution is much wider. There are many people who end up on the far left on this distribution who are talked about 10 times fewer than they should have been. But then also many people on the far right who seem to benefit from propaganda. This picture is the hallmark of censorship in the book record.
  • ELA: So culturomics is what we call this method. It's kind of like genomics. Except genomics is a lens on biology through the window of the sequence of bases in the human genome. Culturomics is similar. It's the application of massive-scale data collection analysis to the study of human culture. Here, instead of through the lens of a genome, through the lens of digitized pieces of the historical record. The great thing about culturomics is that everyone can do it. Why can everyone do it? Everyone can do it because three guys, Jon Orwant, Matt Gray and Will Brockman over at Google, saw the prototype of the Ngram Viewer, and they said, "This is so fun. We have to make this available for people." So in two weeks flat -- the two weeks before our paper came out -- they coded up a version of the Ngram Viewer for the general public. And so you too can type in any word or phrase that you're interested in and see its n-gram immediately -- also browse examples of all the various books in which your n-gram appears.

Opportunities for Creating the Future of Learning - 2020 Forecast: Creating the Future ... - 0 views

  • It remains to be seen whether new learning agents and traditionally certified teachers will cooperate or compete.
  • Secondly, it emphasizes the need for learning to be an ongoing process whereby we all become engaged citizens of a global society. T
  • By embracing technologies of cooperation, prototyping new models of learning, and cultivating open and collaborative approaches to leadership, “amplified” educators and learners will become the organizational “superheroes” of schools and districts.

  • The globalization of open learning systems characterized by cooperative resource creation, evaluation, and sharing will change how educational institutions view their roles and will offer new forms of value in the global learning ecosystem.
  • The result will be an emerging toolset for designing personalized, learner-centered experiences and environments that reflect the differentiation among learners instead of forcing compliance to an average learning style and level of performance.
  • As the hierarchical structure of education splinters, traditional top-down movements of authority, knowledge, and power will unravel. Before new patterns get established, it will seem as if a host of new species has been introduced into the learning ecosystem. Authority will be a hotly contested resource, and there will be the potential for conflict and distrust.
  • Learning geographies will be accessible to communities through a range of key tools, such as data aggregated from disparate sources, geo-coded data linking learning resources and educational information to specific community locations, and visualization tools that help communicate such information in easily understood visual and graphic forms. Such information will often contain multiple layers of data (for example, school performance statistics, poverty rates, and the degree of access to fresh food).
  • These new dimensions of learning geographies will require new core skills. Among them will be navigating new visual cartographies, identifying learning resources in previously unexpected places, leveraging networks to take advantage of learning opportunities, and creating flexible educational infrastructures that can make use of dispersed community resources. Through enhanced visibility and accessibility, learning geographies will bring new transparency to issues of equity in learning.

2010 Horizon Report » Technologies to Watch - 0 views

  • The near-term horizon assumes the likelihood of entry into the mainstream for institutions within the next twelve months; the mid-term horizon, within two to three years; and the far-term, within four to five years. It should be noted that the Horizon Report is not a predictive tool. It is meant, rather, to highlight emerging technologies with considerable potential for our focus areas of teaching, learning, and creative inquiry.
  • virtually all higher education students carry some form of mobile device, and the cellular network that supports their connectivity continues to grow. An increasing number of faculty and instructional technology staff are experimenting with the possibilities for collaboration and communication offered by mobile computing. Devices from smart phones to netbooks are portable tools for productivity, learning, and communication, offering an increasing range of activities fully supported by applications designed especially for mobiles.
  • Far more than a collection of free online course materials, the open content movement is a response to the rising costs of education, the desire for access to learning in areas where such access is difficult, and an expression of student choice about when and how to learn.

  • Already in the mainstream of consumer use, electronic books are appearing on campuses with increasing frequency.
  • applications for laptops and smart phones overlay digital information onto the physical world quickly and easily.
  • Devices that are controlled by natural movements of the finger, hand, arm, and body are becoming more common. Game companies in particular are exploring the potential offered by consoles that require no handheld controller, but instead recognize and interpret body motions.
  • Visual data analysis is an emerging field, a blend of statistics, data mining, and visualization, that promises to make it possible for anyone to sift through, display, and understand complex concepts and relationships.

t r u t h o u t | Dumbing Down Teachers: Attacking Colleges of Education in the Name of... - 0 views

  • the Obama administration's educational policy under the leadership of Arne Duncan lacks a democratic vision and sense of moral direction
  • Almost all of Duncan's polices are indebted to the codes of a market-driven business culture, legitimated through discourses of measurement, efficiency and utility. This is a discourse that values hedge fund managers over teachers, privatization over the public good, management over leadership and training over education. Duncan's fervent support of neoliberal values are well-known and are evident in his support for high-stakes testing, charter schools, school-business alliances, merit pay, linking teacher pay to higher test scores, offering students monetary rewards for higher grades, CEO-type management, abolishing tenure, defining the purpose of schooling as largely job training, the weakening of teacher unions and blaming teachers exclusively for the failure of public schooling.[4]
  • Duncan has expanded the reach of his educational reform policies and is now attempting to rewrite curricular mandates. Emphasizing the practical and experiential, he seeks to gut the critical nature of theory, pedagogy and knowledge taught in colleges of education. This is an important issue to more than just teachers who are denied a voice in curricular development; it also affects whole generations of youth. Such a bold initiative reveals in very clear terms the political project that drives his reforms and what he fears about both public schooling and the teachers who labor in classrooms every day.

  • According to Duncan, the great sin these colleges have committed in the past few decades is that they have focused too much on theory and not enough on clinical practice; and by theory he means critical pedagogy, or those theories that enable prospective teachers to situate school knowledges, practices and modes of governance within wider critical, historical, social, cultural, economic and political contexts. Duncan wants such colleges to focus on practical methods in order to prepare teachers for an outcome-based education system, which is code for pedagogical methods that are as anti-intellectual as they are politically conservative.
  • Rather than provide the best means for confronting "difficult truths about the inequality of America's political economy," such a pedagogy produces the swindle of "blaming inequalities on individuals and groups with low test scores."[7] This is a pedagogy that sabotages any attempt at self-reflection and quality education, all the while providing an excuse for producing moral comas and a flight from responsibility.
  • Duncan's insistence on banishing theory from teacher education programs in favor of promoting narrowly defined skills and practices foreshadows the preparation of teachers as a subaltern class who believe that the purpose of education is only to train students to compete successfully in a global economy. This model of teaching being celebrated here is one in which teachers are constructed as clerks and technicians who have no need for a public vision in which to imagine the democratic role and social responsibility that schools, teachers or pedagogy might assume for the world and future they offer to young people.
  • Duncan then goes on to praise Louisiana as a model for building longitudinal data systems that track the impact of new teachers on student achievement. For Duncan, Louisiana represents a beacon for how schools should be redefined, largely as sites of management and data collection, and advances the notion that teachers should be trained to operate proficiently in such sites.
  • the overuse of harsh discipline disproportionately affects some Louisiana school children over others. African American students make up 44% of the statewide public school population, but 68% of suspensions and 72.5% of expulsions. And in school districts with a larger percentage of African American and low-income students, there are higher rates of suspension and expulsion. These districts tend to have fewer resources for positive interventions.
  • Duncan's collusion with the growing corporatization and militarizing of public schools, along with the increased use of harsh disciplinary modes of punishment, surveillance, control and containment, especially in schools inhabited largely by poor minorities of color, reveals his unwillingness to address the degree to which many schools are dominated by a politics of fear, containment and authoritarianism, even as he advances reform as a civil rights issue.[12] Schools are not merely places where potential workers learn the marketable skills and abilities necessary to secure a decent job, they are also, as Martha C. Nussbaum pointed out, key institutions of the public good and are "crucial to both the health of democracy and to the creation of a decent world culture and a robust type of global citizenship."[13]
  • The diverse range of political, economic, racial and social forces that influence all aspects of schooling need to be critically engaged and rearticulated in the interest of justice, human development, freedom and equal opportunity. These are not merely political issues, they are also pedagogical concerns and the former cannot be separated from the latter, just as equity cannot be separated from matters of excellence. Defining schools exclusively in terms of mathematical coordinates and statistical formulas suggests that Duncan has no language for addressing schools as sites or teachers as engaged intellectuals that mediate, accommodate, reproduce and sometimes challenge the diverse and often anti-democratic forces that bear down on them.
  • What does it mean to ignore the increasing corporatization, privatization and militarization of schools at a time when all aspects of public life are under siege by corporate and market-driven forces? How can schools fulfill their democratic mission when they are shaped by a social order characterized by massive inequalities in wealth and power?
