Is better learning a click away?

Student response systems, or clickers -- not unlike gadgets used on television game shows -- first appeared in college classrooms over a decade ago and have since spread to just about every college and university in the country, thanks to cheaper and better technology. But as clickers have become commonplace, a divide has emerged over just how sophisticated they should be.

Some professors endorse simple, straightforward devices that stick to multiple-choice questions. Others embrace fancier models or newer applications for smart phones and laptops that allow students to query the professor by text or e-mail during the lecture or conduct discussion with classmates -- without the cost of purchasing a clicker. Those preferring simplicity say pared-down remotes reduce distractions in a multitasking world, while others say fighting the march to smart phones and digital tablets is a losing battle. Clickers first gained popularity in large science lecture halls as a way of gauging whether students understood the material. They have since migrated into smaller classrooms and can be found in nursing and other professional schools. Even middle schools and high schools are using them.

Nation's ed tech chief reacts to budget concerns

Karen Cator, director of education technology for the U.S. Department of Education (ED), has heard the concerns from ed-tech groups about President Obama's 2011 budget proposal, which would fold the largest single source of federal funding for school technology equipment, software, training, and support into a larger grant program that aims to promote effective teaching and learning. The concerns about the lack of a dedicated funding stream for education technology in the 2011 budget are "valid," Cator said. But she defended the administration's approach by noting that it encourages the integration of technology throughout all content areas. "Every pot of money is really an opportunity to purchase technology, or to engage with technologies, to reach the goals of the program," she said.

Broadband Can Close the Education Loop

[Commentary] There is some hope that comprehensive broadband build-out in rural areas could provide rural places with the infrastructure they need to provide the jobs that would give those young people a way to stay. But broadband build-out alone will not solve the employment woes of rural areas.

As long as there continues to be a marked gap between the education levels of urban and rural citizens, we cannot expect highly-skilled, well-paying telework jobs to transfer to rural areas of their own accord. There is the possibility, however, that rural broadband build-out could facilitate not only the infrastructure needed to bring telework positions to rural communities, but also provide the means for rural residents to enroll in distance learning courses that will help them to become more competitive in the national and global marketplace. Why distance learning? Historically, rural communities have sought to close the rural/urban education gap by sending their most promising young students to far-away colleges and universities for post-secondary instruction.

On the face of it, this is a seemingly sound plan. However, this strategy has a few crucial shortcomings.

Navajo Nation bridging broadband divide with LTE

Last Friday, one of the first live long-term evolution sites went live in the US, but it wasn't in New York, San Francisco or any of the other major markets of the country. Nor was the cell site deployed by Verizon Wireless, AT&T, MetroPCS or any of the other major wireless operators. Instead the ZTE base station was switched on in Fort Defiance, Arizona, in the heart of the sprawling Navajo reservation.

The Navajo Tribal Utility Authority (NTUA) has partnered with Commnet Wireless to address one of the starkest examples of the digital divide in the US: the 27,000 square-mile Navajo Nation left largely behind by the digital and broadband revolution. Building a wireline broadband network to cover 400,000 people in what is an almost entirely rural reservation the size of West Virginia would be impossible. So NTUA and Commnet have decided to tackle the problem with wireless. "The Navajo Nation has traditionally suffered from a lack of connectivity," said Monroe Keedo, IT manager for NTUA. "The Navajo Nation will benefit from this project in four big ways: economic development, education, public safety and health care."

Public Interest and Media Justice Groups Ask FCC to Address Diversity Problem in Media

A coalition of media justice and public interest organizations sent a letter to Federal Communications Commission Chairman Julius Genachowski yesterday, calling on the agency to make increased diversity in the media and broadband communications landscape a top priority. The groups issued the following joint statement:

"Historically marginalized communities still face countless barriers to their own members' provision and ownership of communications services. The Communications Act instructs the Commission to examine these barriers and take steps to eliminate them. This Commission has taken strides in this area, yet much work remains to be done to address persistent and growing digital divides. We urge the Commission to implement better data-gathering practices regarding the ownership of media outlets by minorities and women, and to examine diversity in pending proceedings at the Commission. For instance, we ask that extensive studies be conducted regarding the potential impact of the proposed merger between Comcast and NBC Universal on the diversity of voices in ownership and programming."

The signatories to the letter include Afro-Netizen; Alliance for Community Media; Benton Foundation; Professor Angela Campbell of Georgetown Law; the Center for Media Justice; the Center for Rural Strategies; Free Press; Main Street Project; Media Access Project; Media Alliance; Mountain Area Information Network; the National Alliance for Media Arts & Culture; the National Association of Hispanic Journalists; the National Federation of Community Broadcasters; Public Knowledge; Reclaim the Media; Texas Media Empowerment Project; United Church of Christ Office of Communication, Inc.; and U.S. Public Interest Research Group.

Hate Paying for Cable? Here's Why.

[Commentary] SNL Kagan has provided some data showing that, when it comes to cable, you are paying a lot for channels you probably never watch.

You'll find this particularly upsetting if you don't watch sports. Because sports channels account for about 40 percent of cable fees. And you'll also be upset once you realize that the broadcast networks -- GE's NBC, News Corp.'s Fox, Disney's ABC and CBS -- are going to get added to this list over the next year or so. Even though anyone who doesn't pay for cable gets them for free.

Consumers In The Dark Over Their Broadband Speeds

Experts say the broadband speeds consumers experience at home are typically 10 percent to 20 percent below the limit that they pay for.

"With broadband, we have allowed ourselves to get into the equivalent of a legitimized con game," says Craig Settles, an industry consultant based in Oakland, Calif. "All of the advertised speeds are speeds that you can't be sure you would get on an average day. It is a theoretical ceiling, if you will, and baseline."

In other words, that 6 megabit DSL connection that you just bought has a potential maximum of 6 megabits. But it's almost certain that you're going to be 10 percent or 20 percent below that limit. Fortunately, there are Web sites like Speedtest.net that you can use to analyze your Internet connection.

Schneier: Fight for online privacy or kiss it good-bye

If the public wants online privacy it had better fight now for laws to protect it because businesses won't and individuals don't have the clout, security expert Bruce Schneier told RSA Conference.

The longer information-privacy policies go unset, the more likely it is that they never will be set, says Schneier, an author of books about security and CTO of security consultant BT Counterpane. As young people grow up with broad swaths of information about them in the public domain, they will lose any sense of privacy that older generations have. And they will have no appreciation that lack of privacy shifts power over their lives from themselves to businesses or governments that do control their information. Laws protecting digital data that is routinely gathered about people are needed, he says. "The only lever that works is the legal lever," he says. "How can we expect the younger generation to do this when they don't even know the problem?"

Supreme Court to Decide Case Involving 'Right of Informational Privacy'

The Supreme Court has agreed to decide whether the First Amendment protects demands for personal information from government contract workers at NASA's Jet Propulsion Laboratory. The case asks whether the Constitution protects a "right of informational privacy."

The Supreme Court mentioned such a right in a 1977 decision, and has seldom mentioned it since. A panel of the San Francisco-based 9th U.S. Circuit Court of Appeals issued an injunction halting the background checks while the suit goes forward, and the full appeals court refused to rehear the case in June. The 9th Circuit's chief judge, Alex Kozinski, highlighted the legal issue when he dissented from the decision not to rehear the case. "Is there a constitutional right to informational privacy? Thirty-two terms ago, the Supreme Court hinted that there might be and has never said another word about it," Judge Kozinski wrote. "With no Supreme Court guidance except this opaque fragment, the courts of appeals have been left to develop the contours of this free-floating privacy guarantee on their own. It's a bit like building a dinosaur from a jawbone or a skull fragment, and the result looks more like a turducken. We have a grab bag of cases on specific issues, but no theory as to what this right (if it exists) is all about."

Facebook Will Allow Users to Share Location

Starting next month, the more than 400 million Facebook users could begin seeing a new kind of status update flow through their news feed: the current locations of their friends.

Facebook plans to take the wraps off a new location-based feature in late April at f8, the company's yearly developer conference, according to several people briefed on the project, who spoke on condition of anonymity because they were not authorized to discuss unannounced services. In preparation for the launch, Facebook updated its privacy policy last November.

The new policy states: "When you share your location with others or add a location to something you post, we treat that like any other content you post."

At that time, the company also offered some foreshadowing of the new feature: "If we offer a service that supports this type of location sharing we will present you with an opt-in choice of whether you want to participate."
