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.

Stop Chasing High-Tech Cheaters | Inside Higher Ed - 0 views

  • It has long been academe's dirty little secret that bad instructors and bad assignments create cheating.
  • "In today's information age, where a body of information in all but the narrowest of fields is beyond anyone's ability to master, why aren't colleges teaching students how to research, organize and evaluate the information that is out there?"
  • If, however, processing information is the issue, if creative solutions are being sought, if students are being asked to develop new syntheses, then cheating will be much rarer, and much more difficult, technology use will become essential, and learning will be far more relevant.
  • ...2 more annotations...
  • So schools do not teach effective use of Google, of text-messaging, of instant-messaging. They don't teach collaboration. They barely teach communication outside the stilted prose only academics use. No wonder students are prepared for nothing except more school.
  • There is also the issue of educational discrimination. When schools fight against technology, they are fighting access to education for people who learn and function differently. Technology, from computers to calculators to classroom cellphones, enables a wide variety of students who would otherwise be left out to participate and succeed. Technology in the hands of all students allows disabilities and functional deficits to be invisibly accommodated so that knowledge can be developed, nurtured, and evaluated on terms fair to everyone.So, no, the problem is not cheating. The problem is firmly one of instructional and evaluation technique. It will not be solved until teachers and professors figure out that understanding and the ability to work with knowledge is what counts, and that anything you can instantly Google, or store in your calculator, or retrieve via quick text-message or phone call need not be remembered, nor tested, because, obviously, you will always be able to instantly Google it, or store it in your cellphone, or get someone to text it to you.

ASCD Express 5.18 - Cell Phones Allow Anytime Learning - 0 views

  • She is currently writing a book tentatively titled Cases for Using Students' Cell Phones in Education: A Practical Guide to Using Cell Phones in K–12 Schools, which looks at 11 U.S. and 5 international case studies of teachers integrating students' own cell phones into instruction.
  • One of Larry Cuban's (Teachers and Machines, Oversold and Underused) theories about why ed technology often fails in schools is that we use this top-down approach where administrators or tech coordinators introduce the technologies to the teachers, and they in turn try to introduce and teach it to the students. It's a very foreign concept for the students, as well as the teachers. And often what happens is maybe a handful of teachers end up using this very expensive technology, and students don't have any access to it outside of school. Cuban recommends a much more bottom-up approach to ed technology. Rather than making specialized software and hardware just for school learning, students and society introduce the technologies that schools should be integrating into learning.
  • People who know the history of ed technology know that it hasn't been that successful, long-term, with sustaining learning because it's often attached to a tool that students don't have access to outside of school.
  • ...3 more annotations...
  • For many schools, the hardest part is making it acceptable to turn to technologies that aren't traditionally used in schools. It's a culture that has to be cultivated at the school itself. In the book I'm working on now, many of the teachers in the case studies I discuss approached their administrators with something they'd been using with success outside of school, and their administrators were open to trying it out within school. Kipp Rogers at Passages Middle School in Newport News, Va., has done a phenomenal job modeling that approach and valuing not only his teachers, but also his students, who are involved in planning, as well.
  • Q: From what you've seen in the field, what's the most interesting instructional use of mobile devices happening now? Keren-Kolb: Definitely what's going on in Australia. Teachers are using QR (two-dimensional bar codes) for activities and learning. In the United States, about 60 percent of the phones can do this, but in most other countries, it's almost universal. So, in some Australian schools, this means [that] students come in on the first day of class and their entire syllabus is on a bar code they scan directly into their phone—same thing with some books and homework assignments. They'll scan a code for their homework, and it'll link to video tutorials and activities. So, moving away from textbooks and moving toward paperless learning that's much more interactive. I think that's exciting—how much information you can attach to that little bar code, and use it to extend learning.
  • When students can use whatever tools are around them, obviously, testing changes. It's not just about a right or wrong answer—it's about inquiry, collaboration, and the higher-order thinking skills we want students to do.

Textbooks, E-books, and Online Learning « The Xplanation - 0 views

  • textbooks, with or without the bundled DVDs, are what Judy Baker, of the Community College Consortium for Open Educational Resources, calls “The Hummer of higher education.” Why should we be content with static, rapidly outdated, heavy print textbooks that can cost community college students as much as their tuition, when professors and students can work together to create dynamic, rich-media learning environments instead using free and open source software tools?

Presentation Zen Bento Box - dr. jude rathburn's posterous - 0 views

  • Take an hour to show Garr's award winning Presentation Zen video (included in the bento box) so that people can see the principles in action before trying to design their own presentations. 
  • since viewers are not familiar with the approach, I found it is helpful to take some time to discuss each element.
  • rovide risk-free (i.e. low stakes) opportunities for learners to practice various elements of the Presentation Zen approach, share the results and provide peer reviews.
  • ...5 more annotations...
  • In my senior level strategic management seminar I asked people to break up into groups of three and then distributed a Fortune article about a local firm so that we would all be working with the same course-related content.  I gave them class time to read the article and also provided an organizing framework to help them focus on the main themes regarding the company's business strategy.  I also printed out a blank storyboard using the 3-slide handout feature in MSPowerPoint and distributed a few copies to each group.  Their task was to come to some consensus about the most interesting aspect of the company's strategy and identify the one central point that they wanted to get across in their 2-3 minute presentation.  The only other constraints were that they had to include one slide that highlighted some data that supported their central point and they had to create their storyboard and script in analog form before they opened their laptops. 
  • I asked each group to create a narrated presentation using either Keynote or PowerPoint, which they then uploaded to a discussion forum in our web-based course management system.  Each student also reviewed at least one other group's presentation, providing feedback on content, as well as the application of the Presentation Zen approach.  I provided feedback in the forum as well, commenting on the presentations themselves and the peer reviews.  Everyone who participated got full credit, which is why I referred to the practice presentation and peer review as a risk-free or low stakes activity.
  • Provide an example of a presentation that used the Presentation Zen approach, along with the storyboard and script
  • It also opens the door for viewers to give me feedback on the effectiveness of the design decisions I made and offer suggestions on how to improve my presentation.  I have found that opening up the conversation and giving students permission to review my work helps to strengthen our connection and improves my practice at the same time.  It also helps me demonstrate that it takes time and practice to implement the PZ approach - we are all a work in progress!
  • My final tip, at least for now, is to give people plenty of opportunities to practice using the Presentation Zen approach and give and receive feedback.  My students decided they wanted to create at least four presentations throughout the course to demonstrate their understanding of course concepts and their ability to apply those concepts to real world examples.

When college students reinvent the world - CSMonitor.com - 0 views

  • Cultural anthropology professor Michael Wesch came up with “World Sim” to push students to stop asking, “What’s going to be on the test?” and to contemplate bigger questions: Why are some people poor and some rich? How does the world work?
  • The goal, he says, is to create an environment where students can expand their capacity for empathizing with and loving those who are different from them.
  • Professor Wesch sets up the simulation by giving each culture a certain amount of power in the beginning – symbolized by playing cards. Then, based on a complex set of rules the class has devised together, students go through each round of the game – striking alliances, trading cards, and sometimes starting “wars” over resources.

News: The Evidence on Online Education - Inside Higher Ed - 0 views

  • The study found that students who took all or part of their instruction online performed better, on average, than those taking the same course through face-to-face instruction. Further, those who took "blended" courses -- those that combine elements of online learning and face-to-face instruction -- appeared to do best of all. That finding could be significant as many colleges report that blended instruction is among the fastest-growing types of enrollment.
  • While the new study provides a strong endorsement of online learning, it also notes findings about the relative success (or lack thereof) of various teaching techniques used in online courses. The use of video or online quizzes -- frequently encouraged for online education -- "does not appear to enhance learning," the report says.
  • But noting the caveats in the report about factors other than medium of instruction, he said that "we should not take the report as saying it is simply better to move to online learning. These results demonstrate why more research is needed -- broadly based research that moves well beyond case studies conducted by distance education practitioners, research focused on student retention in online environments and especially research that looks behind the instructional medium to isolate the characteristics of instruction that produce positive results. Successful education has always been about engaging students whether it is in an online environment, face to face or in a blended setting. And fundamental to that is having faculty who are fully supported and engaged in that process as well."

  • "Despite what appears to be strong support for online learning applications, the studies in this meta-analysis do not demonstrate that online learning is superior as a medium," the report says. "In many of the studies showing an advantage for online learning, the online and classroom conditions differed in terms of time spent, curriculum and pedagogy. It was the combination of elements in the treatment conditions (which was likely to have included additional learning time and materials as well as additional opportunities for collaboration) that produced the observed learning advantages. At the same time, one should note that online learning is much more conducive to the expansion of learning time than is face-to-face instruction."
  • Using technology to give students "control of their interactions" has a positive effect on student learning, however. "Studies indicate that manipulations that trigger learner activity or learner reflection and self-monitoring of understanding are effective when students pursue online learning as individuals," the report says.Notably, the report attributes much of the success in learning online (blended or entirely) not to technology but to time. "Studies in which learners in the online condition spent more time on task than students in the face-to-face condition found a greater benefit for online learning," the report says.
