Robots in Education

Robots are increasingly becoming ubiquitous in education. The Google Lunar X Prize, a $30 million contest to design a robot capable of traveling to the moon, is being envisioned for children by the X Prize Foundation, Google, Lego Systems, and National Instruments on MoonBots. The winner of the Google Lunar X prize can send his or her robot to the moon to gather information, photographs, and video footage to send back to Earth. Children can assemble robots that imitate the same tasks using a Lego Mindstorm kit. The Franklin W. Olin College of Engineering has a Senior Capstone Program in Engineering (Scope) that asks students to work on a large engineering project that simulates the kind of problems they would tackle in the corporate world. Vision Robotics Corp (VRC) has asked the Scope group to help them design fruit-picking robots. The first robot finds the fruit, and the second picks it. The team of seniors designed an end effector that can select the fruit, and the device has been added to a working model of the fruit-picker. Researchers from Nanyang Polytechnic, Schmid Engineering, and Analog Devices--from Singapore, Switzerland, and the U.S., respectively--have put together a spider robot that can crawl into small places and across difficult surfaces. Equipped with six legs, the robot can move in any direction, either slowly with all six of its limbs or more quickly with just three. Scope director David Barrett says that robots are the new groundbreaking technology, in use today "in the military, in industries and the consumer level."

Open Web Education Alliance

The World Wide Web Consortium (W3C) is creating the Open Web Education Alliance (OWEA), a new body designed to help ensure that educational institutions around the world are providing Web professionals and information technology graduates with the skills the industry needs. OWEA co-chair John Allsopp says students might learn things that are relevant to their role in the industry, but the fast-evolving nature of the Web often requires Web practitioners to teach themselves new skills. "The goal is to create a sustainable organization to promote best practices in education for Web professionals, working to both develop curricula itself and promote this within universities, colleges, private education providers, and inside large organizations," Allsopp says. "There's a strong belief within the industry that something like this is really needed and we are currently investigating different models of sustainability for the organization." OWEA, which is expected to launch in 2010, is preparing a white paper on its operational plans for the W3C. A dozen international Web professionals are involved with OWEA, which also is backed by Microsoft, Adobe, and Opera Software.

Wimax: City-Wide Wireless Service

Cities will be transformed by WiMax, smart grids, social networks, and other emerging technologies, once they are cohesively integrated. WiMax is seen as a critical tool for supporting city-wide wireless services. WiMax offers more ubiquitous access than Wi-Fi, because WiMax is available throughout a given area while Wi-Fi hot spots require users to search for them. The notion of the smart grid is oriented around the idea of using electricity when it is available at low cost rather than at peak periods, and the integration of renewable energy sources into the grid via two-way communication between utility companies and the businesses and individuals who use their power. There might be a central command center for overseeing and adjusting power usage and for delivering information technology (IT) services through WiMax, but the actual IT operation could reside in the computing cloud rather than in the city's data center. Social networking technology also is being tapped to provide online services through which citizens can keep up with local developments and comment on neighborhood issues. For example, Dublin, Ohio, uses networking software to operate a portal where government officials can post blogs, engage in dialogue via instant messaging, and share documents. Dublin plans to make the private network accessible to all citizens over the next several months.

LifeLogging

Pioneering Microsoft researcher Gordon Bell has been recording and storing virtually every aspect of his daily life in an effort to build a searchable electronic memory for everyone, and he speculates that increasing numbers of people will be doing the same in the future. He envisions the practice of lifelogging as the logical next step up from social networking. The cell phone is already a rudimentary instrument for lifelogging, and support of the practice is increasing as phones add more features to record daily activities. Concurrent with this trend is the development of specialized devices and Web services geared toward lifelogging enthusiasts. For example, Zeo is a sleep-monitoring gadget that maps out the patterns and quality of each night's sleep, while an accompanying Web service helps users optimize their sleep habits. Livescribe, meanwhile, is a digital pen that converts notes and sketches into image files and records the sound of conversations, lectures, and conferences. Analyst Esther Dyson forecasts that markets will open for software to "extract order and meaning from the chaos of proliferating data."

Scala Programming Language

The Scala programming language, which runs on the Java Virtual Machine, could become the preferred language of the modern Web 2.0 startup, according to a Twitter developer. Scala creator Martin Odersky says the name Scala "means scalable language in the sense that you can start very small but take it a long way." He says he developed the language out of a desire to integrate functional and object-oriented programming. This combination brings together functional programming's ability to build interesting things out of simple elements and object-oriented programming's ability to organize a system's components and to extend or adapt complex systems. "The challenge was to combine the two so that it would not feel like two languages working side by side but would be combined into one single language," Odersky says. The challenge lay in identifying constructs from the functional programming side with constructs from the object-oriented programming side, he says. Odersky lists the creation of the compiler technology as a particularly formidable challenge he faced in Scala's development. He notes that support of interoperability entailed mapping everything from Java to Scala, while another goal of the Scala developers was making the language fun to use. "This is a very powerful tool that we give to developers, but it has two sides," Odersky says. "It gives them a lot of freedom but with that comes the responsibility to avoid misuse."

Online vs Clasroom Education

Students' performance in online education settings tended to trounce that of those receiving face-to-face instruction, according to a study SRI International carried out for the U.S. Education Department. The study analyzed the comparative research on traditional versus online education over a 12-year period, with the bulk of the studies done in colleges and various adult continuing-education programs. The report found 99 studies in which there were quantitative comparisons of online and classroom performance for the same courses, and an analysis determined that students doing some or all of the course online would rank in the 59th percentile in tested performance on average, versus the average classroom student scoring in the 50th percentile. Lead study author Barbara Means says the report indicates that online learning often outclasses traditional instruction, and the report suggests that online education could experience sharp growth during the next several years. Experts say the real promise of online education is delivering learning experiences that are more customized to individual students than classrooms, which facilitates more learning by doing. Philip R. Regier, with Arizona State University's Online and Extended Campus program, expects continuing education programs to exhibit the most growth in the near term, and he also predicts that online education will continue to gain ground in the transformation of college campuses. Regier says the growing use of social networking technology will hasten the evolution of online learning into a model where students help and teach each other by creating new forms of learning communities.

International Symposium on Wikis

The explosive growth of the Wikipedia online encyclopedia is petering out, while a less welcoming attitude toward new contributors could negatively affect the archive's quality in the long term, according to a team of Palo Alto Research Center (PARC) researchers. The number of articles added to the Web site per month reached a plateau at 60,000 three years ago and has since fallen by about one-third, while the number of edits made every month and the number of active editors both stopped expanding in 2007. Occasional editors' power has thinned as more active and established editors come to dominate, and infrequent contributors have a greater percentage of their additions deleted or reverted by other editors than they did before. "This is evidence of growing resistance from the Wikipedia community to new content," says the PARC team. PARC researcher Ed Chi cautions that this resistance could hurt Wikipedia in the longer term by discouraging participation by new editors, thus reducing the number of editors available to identify and repair vandalism. "Over time the quality may degrade," Chi says. The PARC researchers will present their findings at the International Symposium on Wikis and Open Collaboration in October. Blue Oxen Associates' Eugene Eric Kim, who is helping to lead a review of Wikipedia launched by the Wikimedia Foundation, says there are several possible reasons for the changes Wikipedia has undergone. He posits, for example, that the increasing use of spam software that embeds promotional text in articles may actually be responsible for the high number of reverts.
