Contemporary Issues in Technology and Teacher Education [Online serial], 4(1). Going Mobile: Debating and Using Cellphones in School George Osodi/Associated PressAt an electronics market in Lagos, Nigeria, cellphones appear in great profusion, as they do throughout poorer lands.Go to related article » Overview | Can cellphones serve as effective instructional tools in the classroom? In what ways can the use of mobile technology support and strengthen curriculum? What are the drawbacks? In this lesson, students learn about innovative uses of cellphone technology and applications in the developing world, then explore how their phones can be used as learning tools. Teachers | Do you use cellphones in your classroom?
New audio coding system solves audio latency problem A new codec (data coding system) called Enhanced Low Delay Advanced Audio Coding (AAC-ELD) developed by researchers at the Fraunhofer Institute for Integrated Circuits IIS has solved a major problem with Skype and other videoconference calls: latency (annoying sound delay between participants). Their new Enhanced Low Delay Advanced Audio Coding (AAC-ELD) allows for latency only about 15 milliseconds. In the process, they also managed to reduce the audio data to less than one-thirtieth of its original size without major loss of sound quality, thus reducing the required bandwidth. The researchers developed an algorithm that requires a certain amount of time to encode data and then decode it again at the other end of the line. The process requires data that is still in the future, as it must wait for the data to arrive. To test the new codec, they developed an app to play games across the borders of cities or countries.
Ushering iPad into the Classroom Mobile Computing | Spotlight Ushering iPad into the Classroom A number of built-in features, tools, and add-ons are helping to propel Apple's iPad into the classroom. Technology analyst Denise Harrison looks at the benefits of iPad in education and predicts some unanticipated applications Tablet devices are hardly new; Apple's own Newton, introduced in 1987, could fairly be called an ancestor to the iPad with its tablet form, tethered pen touch interface, and easy portability.
Sony network breach shows Amazon Cloud’s appeal for hackers The hackers that brought down Sony’s Playstation Network for more than a month used stolen credit cards to rent computing power from Amazon’s Elastic Computing Cloud (EC2) to carry out their attack. Personal information, credit cards, and passwords from millions of customers were seized by hackers during the attack. Because computing power can be rented from EC2 anonymously, hacking using the service can be hard to trace. Tracing the attack may require the FBI seeking a search warrant to access Amazon’s detailed records of which IP addresses accessed the service at which time, and tracing those IP addresses to homes or businesses. The Playstation Network remains down in Japan due to government concerns over its security.

How to tell when someone’s lying Professor of psychology R. Edward Geiselman at the University of California, Los Angeles, has been studying for years how to effectively detect deception to ensure public safety, particularly in the wake of renewed threats against the U.S. following the killing of Osama bin Laden. Geiselman and his colleagues have identified several indicators that a person is being deceptive. The more reliable red flags that indicate deceit, Geiselman said, include: Educational Technology Guy Why the eye is better than a camera This graph of neurotransmitter release shows what happens when cone cells are exposed to a dark spot in a light background (top) under various scenarios, including no feedback (green trace) and only negative feedback from horizontal cells (red trace). Negative feedback to many cones enhances edges, but would decrease detail in dark areas were it not for newly discovered positive feedback that is localized to only a few cone cells (blue trace) (credit: Richard Kramer’s lab, UC Berkeley) The retina’s tricks for improving contrast and sharpening edges without sacrificing shadow detail have been revealed in experiments by neurobiologists at the University of California, Berkeley. The retina in vertebrates is lined with a sheet of photoreceptor cells: the cones for day vision and the rods for night vision. That extra boost preserves the information in individual light detecting cells (rods and cones) thereby retaining faint detail while still enhancing contrast.
