When these learners complete the program, they have competencies relevant to 21c life-- they can communicate, collaborate, access and integrate information from diverse sources using electronic libraries. It is an exciting way to teach and learn and it is the wave of the future so we need to gain the skills needed to make these educational experiences consistently meaningful.

Working with online instruction requires different techniques. An instructor online cannot usually look at a student's face and see that she isn't grasping the point, for example, or when she has fallen asleep. I can see why instructors would miss this type of face-to-face communication; online feedback is both less immediate and in some cases more direct. But a lecture can be truly engaging or enormously incomprehensible even for the student who moves to the front row to try to understand it all. Online learning can also reap huge results or can suffer from another set of equally mind-numbing problems.

I have to agree with jsalmons and bghansel. It's not the fact that a school is online or on-ground that matters. It's the quality of the educator that matters. I, too, have gone to and taught in Ivy League schools and found them to be a mixed bag, just as I've found online schools to be a mixed bag.

Yes, softshellcrab, discussion questions are the backbone of online courses. Are you telling me they don't play a role in on-ground education? Are you telling me that only talking-head lectures educate? Is there something wrong with students doing self-studying? Haven't you seen lecture content in online courses? I'm puzzled as to why you think critical thinking, Socratic reasoning/questioning, and constructivism are bad or can't be done online, but can on-ground.

The most (Stress THE MOST)primary issue with distance education is the degree of affective education taught.

We can use SKYPE, WIMBA or other "video" based education, but what we lose is the subtle differences of students and their interactions with others that makes it difficult to determine their level of character (highest level of affect).

Bill Gates may think we will have less seated instruction in the future (see another Chronicle issue elsewhere), but the backlash against online will be in the form of those who cannot interact and thus not obtain jobs (except in the places where it wont matter because none have any affect in that place).The bottom line is that we are losing a major portion of our education system in a pure online education format. Until we recognize how to better teach affective education with online, and more importantly assess that type of education, we will have major issues not only in higher education, but also in industry/business.And this is an open invitation for Bill Gates to discuss this issue.

"Quality on-line teaching is harder than regular classroom teaching, but poor on-line teaching is easier than regular classroom teaching."

But can I make it more specific - "Quality on-line teaching is harder (taking more time, e.g.)than regular classroom teaching of the same quality (in achieving the same extent of satisfaction in students, e.g.)?"

However, no one has mentioned the preparation required for quality online instruction. Some building blocks of good online programs are high quality/targeted content, flexible tools for development and delivery, engaging and interactive design, attentive and responsive instructors during the class, self motivated learners, and as always outcomes-based curriculum.

It would be interesting to pull the data in from previous decades and see how the elevation has changed in different areas.

@adrian – it’s just raw totals, grouped geographically. These aren’t scientific by any means, I basically took the underlying pattern and extruded it out and smoothed it a bit to make it look “pretty”. But basically each image is the aggregate numbers for a single year of crime data.

@richard – yes, there is some smoothing in effect, which means that the ridge along Shotwell St (for the prostitution map) is indeed a bit smoothed between peaks. That’s not to say that there are only two peaks at Shotwell and 19th and Shotwell and 17th. There are incidents in between as well, but the big peaks at those major intersections does mean that the ridge between them appears higher than the actual incidents along those blocks support. A lot of people have commented on the usefulness of maps like these. I want to stress once again: this was done as an art project much more than a useful visualization. My goal was not to provide useful information that one could act on.

“one trick pony. these maps add nothing of value to a standard color plot.” I disagree: allowing for a third dimension of elevation makes the reality of concentration clearer – and half the point of crime mapping is to measure concentration, not simply “intensity.”

Great idea and nice work on the graphics, but there are at least three improvements you should make to reveal *true* patterns. Forgive me if you already did these. 1) Availability bias – normalize for population density (i.e. per capita activity) 2) Sampling bias – normalize for the number of cops on the beat (geographic and crime type) 2) Frame bias – break it up by daytime and night time

The interwoven characters, relationships, settings, and scenes that result are the stuff of stories, regardless of how closely mapped onto reality they might be; this also distinguishes a Web 2.0 story from other blogging forms, such as political or project sites (except as satire or criticism!).

in sharp contrast to the singular flow of digital storytelling. In the latter form, authors create linear narratives, bound to the clear, unitary, and unidirectional timeline of the video format and the traditional story arc. Web 2.0 narratives can follow that timeline, and podcasts in particular must do so. But they can also link in multiple directions.

So Professor Shankar has begun inserting links to specific portions of Professor Lewin’s course, and, “since any mistake would affect larger numbers of students listening online,” he says, he thinks harder about every topic he teaches in the classroom.

His intense, animated ruminations — the title of his course is “Death” — have brought fan mail from Mexico, Iraq, Korea and China. Several months ago, he got a response from somebody suffering from a brain injury and who was using the lectures to exercise his mind. “I don’t think anyone knows what this will do to education 15 years from now,” Professor Kagan says. “But even if it does nothing more than that, that’s enough.”

The backers of free courseware acknowledge the benefit of self-enrichment. Still, they say they expect open education not only to expand access to information but also to lead to success in higher education, particularly among low-income students and those who are first in their family to go to college.

Carnegie Mellon’s Open Learning Initiative is working with teams of faculty members, researchers on learning and software engineers to develop e-courses designed to improve the educational experience.

Carnegie Mellon is working with community colleges to build four more courses, with the three-year goal of 25 percent more students passing when the class is bolstered by the online instruction.

The intended user is the beginning college student, whom Dr. Smith describes as “someone with limited prior knowledge in a college subject and with little or no experience in successfully directing his or her own learning.”

. “We now have the technology that enables us to go back to what we all know is the best educational experience: personalized, interactive engagement,” Dr. Smith says.

That won’t happen, and in the terms-of-use section of Open Yale Courses, the university makes that clear. Besides not granting degrees or certificates, open courses do not offer direct access to faculty. They, in other words, are strictly “for those who wish to learn,” as the Web site says. “Its purpose is not to duplicate a Yale education.”

Open courseware is a classic example of disruptive technology, which, loosely defined, is an innovation that comes along one day to change a product or service, often standing an industry on its head. Craigslist did this to newspapers by posting classified ads for free. And the music industry got blindsided when iTunes started unbundling songs from albums and selling them for 99 cents apiece.

Mr. Schonfeld sees still more potential in “unbundling” the four elements of educating: design of a course, delivery of that course, delivery of credit and delivery of a degree. “Traditionally, they’ve all lived in the same institutional setting.” Must all four continue to live together, or can one or more be outsourced?

P2PU’s mission isn’t to develop a model and stick with it. It is to “experiment and iterate,” says Ms. Paharia, the former executive director of Creative Commons. She likes to talk about signals, a concept borrowed from economics. “Having a degree is a signal,” she says. “It’s a signal to employers that you’ve passed a certain bar.” Here’s the radical part: Ms. Paharia doesn’t think degrees are necessary. P2PU is working to come up with alternative signals that indicate to potential employers that an individual is a good thinker and has the skills he or she claims to have — maybe a written report or an online portfolio.

David Wiley, associate professor of instructional psychology and technology at Brigham Young University, is an adviser to P2PU. For the past several years, he has been referring to “the disaggregation of higher education,” the breaking apart of university functions. Dr. Wiley says that models like P2PU address an important component missing from open courseware: human support. That is, when you have a question, whom can you ask? “No one gets all the way through a textbook without a dozen questions,” he says. “Who’s the T.A.? Where’s your study group?” “If you go to M.I.T. OpenCourseWare, there’s no way to find out who else is studying the same material and ask them for help,” he says. At P2PU, a “course organizer” leads the discussion but “you are working together with others, so when you have a question you can ask any of your peers. The core idea of P2PU is putting people together around these open courses.”

Mr. Reshef’s plan is to “take anyone, anyone whatsoever,” as long as they can pass an English orientation course and a course in basic computer skills, and have a high school diploma or equivalent. The nonprofit venture has accepted, and enrolled, 380 of 3,000 applicants, and is trying to raise funds through microphilanthropy — “$80 will send one student to UoPeople for a term” — through social networking.

Mr. Reshef has used $1 million of his own money to start the University of the People, which taps open courses that other universities have put online and relies on student interaction to guide learning; students even grade one another’s papers.

"It is a sea change in the way the industry works," says Omar Tawakol, CEO of BlueKai. "Advertisers want to buy access to people, not Web pages."

The Journal found that Microsoft Corp.'s popular Web portal, MSN.com, planted a tracking file packed with data: It had a prediction of a surfer's age, ZIP Code and gender, plus a code containing estimates of income, marital status, presence of children and home ownership, according to the tracking company that created the file, Targus Information Corp.

Tracking is done by tiny files and programs known as "cookies," "Flash cookies" and "beacons." They are placed on a computer when a user visits a website. U.S. courts have ruled that it is legal to deploy the simplest type, cookies, just as someone using a telephone might allow a friend to listen in on a conversation. Courts haven't ruled on the more complex trackers.

tracking companies sometimes hide their files within free software offered to websites, or hide them within other tracking files or ads. When this happens, websites aren't always aware that they're installing the files on visitors' computers.

Often staffed by "quants," or math gurus with expertise in quantitative analysis, some tracking companies use probability algorithms to try to pair what they know about a person's online behavior with data from offline sources about household income, geography and education, among other things. The goal is to make sophisticated assumptions in real time—plans for a summer vacation, the likelihood of repaying a loan—and sell those conclusions.

Consumer tracking is the foundation of an online advertising economy that racked up $23 billion in ad spending last year. Tracking activity is exploding. Researchers at AT&T Labs and Worcester Polytechnic Institute last fall found tracking technology on 80% of 1,000 popular sites, up from 40% of those sites in 2005.

The Journal found tracking files that collect sensitive health and financial data. On Encyclopaedia Britannica Inc.'s dictionary website Merriam-Webster.com, one tracking file from Healthline Networks Inc., an ad network, scans the page a user is viewing and targets ads related to what it sees there.

Beacons, also known as "Web bugs" and "pixels," are small pieces of software that run on a Web page. They can track what a user is doing on the page, including what is being typed or where the mouse is moving.

The majority of sites examined by the Journal placed at least seven beacons from outside companies. Dictionary.com had the most, 41, including several from companies that track health conditions and one that says it can target consumers by dozens of factors, including zip code and race.

After the Journal contacted the company, it cut the number of networks it uses and beefed up its privacy policy to more fully disclose its practices.

Flash cookies can also be used by data collectors to re-install regular cookies that a user has deleted. This can circumvent a user's attempt to avoid being tracked online. Adobe condemns the practice.

Most sites examined by the Journal installed no Flash cookies. Comcast.net installed 55.

Wittingly or not, people pay a price in reduced privacy for the information and services they receive online. Dictionary.com, the site with the most tracking files, is a case study.

Think about how these technologies and the associated analytics can be used in other industries and social settings (e.g. education) for real beneficial impacts. This is nothing new for the web, the now that it has matured, it can be a positive game-changer.

Media6Degrees Inc., whose technology was found on three sites by the Journal, is pitching banks to use its data to size up consumers based on their social connections. The idea is that the creditworthy tend to hang out with the creditworthy, and deadbeats with deadbeats.

"There are applications of this technology that can be very powerful," says Tom Phillips, CEO of Media6Degrees. "Who knows how far we'd take it?"

Hidden inside Ashley Hayes-Beaty's computer, a tiny file helps gather personal details about her, all to be put up for sale for a tenth of a penny.

"We can segment it all the way down to one person," says Eric Porres, Lotame's chief marketing officer.

One of the fastest-growing businesses on the Internet, a Wall Street Journal investigation has found, is the business of spying on Internet users.

Yahoo Inc.'s ad network,

"Every time I go on the Internet," she says, she sees weight-loss ads. "I'm self-conscious about my weight," says Ms. Reid, whose father asked that her hometown not be given. "I try not to think about it…. Then [the ads] make me start thinking about it."

Information about people's moment-to-moment thoughts and actions, as revealed by their online activity, can change hands quickly. Within seconds of visiting eBay.com or Expedia.com, information detailing a Web surfer's activity there is likely to be auctioned on the data exchange run by BlueKai, the Seattle startup.

Language content makes up about 95 percent of the downloads from the Emory iTunes U site.

the most popular content is audio and video files that were originally developed not for a general audience, but by professors as supplements to college-level coursework,

Because language demonstrations often require audio and sometimes video components (e.g., tutorials on how to write in a character-based alphabet), and students often like to practice while on the move, iTunes is in many ways an ideal vehicle for language-based instructional content.

what we do offer is an online supplement that enhances what happens both in the classroom and in foreign study in the culture — and it is always there as a resource for our students, because it’s online.”

To Orange, I will show an actual example of a map in my next full post and explain more about the parameters that are given and what the students fill in themselves. You raise a much more important question though, about the necessity of simplifying in order for the simulation to work. This aspect of the simulation almost led me to abandon the whole thing as I started to think it through and plan for it. Instead I found two ways to deal with it: 1. I challenge my students to tell me where the simulation is oversimplified and make their own case for how the simulation should change for the next time it is performed. This way they are not simply accepting our imaginary world “as is” and are instead actively thinking about how the real world works and how we may have misrepresented it in our simulation. (Even if the simulation fails miserably, it has succeeded in getting students to think about how the world works!) 2. I encourage the students to use the simplification as a canvas on which they can build and/or interpret complexity. In a lecture format I only have so much time to cover the effects of colonization – perhaps 50 minutes – not enough to really explore all of the different facets. In the World Simulation I can encourage each student to think about how colonization would affect their culture in multiple ways and at multiple levels (e.g. infrastructure, social structure, superstructure). Sometimes this is to complex to be incorporated into the simulation, but they are asked to do a reflection paper immediately following the simulation in which they write their own “cultural history.” This written format allows them to explore some complexities they might not have had the time or means to express in the simulation.
