I am skeptical that distance education based on asynchronous Internet technologies (i.e., prerecorded video, online forums, and email) is a substitute for live classroom discussion and other on-campus interaction. Distance education students can't raise their hands to ask instructors questions or participate in discussions, and it's difficult or impossible for them to take advantage of faculty office hours. Teaching assistants don't always respond to email, and online class discussion boards can be neglected by students and faculty alike. In this sense, the "process of dialogue" is actually limited by technology.

In the online math class, there was almost no meaningful student/teacher or student/student interaction. To equate this type of online learning with a real-world classroom experience is a major stretch.

The most effective learning takes place in the classroom, where you can easily raise your hand, engage in spontaneous discussions with classmates and faculty, turn to the person next to you to ask for clarification, or approach the professor after class or during office hours to ask questions or exchange viewpoints in a way that practically guarantees an instant response and is not constrained by typing, software interfaces, or waiting for a response.

Not only are we digital immigrants, we are also media dinosaurs. We enjoy thumbing through glossy magazines, and maybe still subscribe to a daily newspaper. We schedule at least one evening per week around a favorite TV program, created by one of the major television or cable networks. We can name at least one local or national news anchor. And scattered around our homes and offices are veritable graveyards of physical media — old tapes, vinyl records, floppy disks, and magazines — that we insist on keeping, even though we'll probably never use them again.

Old media companies will be further challenged in the next 15 years, as a new wave of user-generated content washes over the Internet, thanks to the increasing availability and affordability of portable, digital-based electronic devices. The cameraphones which seemed like such novelties just a few years ago will be in everyone's purse and pocket a few years from now.

Get used to the idea of significant portion of the population walking around with high-speed Internet connections on their person, with sophisticated video cameras built in. They will be shooting all kinds of events all the time. Crime. Crashes. Speeches. Sports. And the footage won't be the short, sanitized and safe versions we usually see on television, courtesy of the old media gatekeepers. The user-generated pictures and video will be raw and real. It will be disturbing, yet illuminating. And it will be shared over the 'Net almost as it happens, and available for everyone to see.

Manuscript editions didn't immediately die out with the printing explosion that burst across Europe in the 1460s and 1470s. Manuscripts continued to be produced into the 16th century, many decades after presses had spread to most minor cities in Western Europe.

In business presentations, positive impressions can help make a sale or win over an audience.

Twitter is more than just a collection of fleeting observations about everyday life. Twitter can connect people to events, information and each other in ways that have never been experienced before.

Tweets about the mundane aspects of your life contain something that is vitally important to gaining followers and taking part in discussions: Authenticity.

The starting point for ‘discounts’ may be the manufacturer’s suggested retail price (MSRP), an arbitrarily high price that no one will ever pay. By crossing out the high MSRP, retailers are handing shoppers a psychological victory that will make them feel good about the purchase, even if the discounted price is still expensive.

At the end of the day, taking 50% off a $250 dress still means walking out of the store $125 poorer.
