With school enrollment projected to increase at record levels through 2013, and spending on school construction, renovation and maintenance expected to total nearly $30 billion annually, the need to transform our schools has never been more urgent. To learn how you can help schools make better design decisions, attend the Schools of the 21st Century Symposium on March 28, 2008, in Orlando, Florida. The event is presented by Architectural Record with the support of McGraw-Hill Education and the American Architectural Foundation.

In some cases, the difficulties of hardwiring old schools can be eased by portable devices and digitally based curricula

The firewall factor
Portable technology, however, brings its own security issues. Mario Sanchez, a technology consultant with Los Angeles-based EQ International (part of RTKL Architects), says that as schools establish virtual private networks (VPNs) to allow students’ laptops to access school networks from home, care should be given to implement appropriate security through smart cards or thumbprint identification to ensure computers are used only by the students. “You can install software to automatically lock down a laptop if a student stops attending school,” Sanchez says. With encryption software, automatically updated Internet filtering, and stronger firewalls, he says, the concerns that outsiders might access wireless networks or students could download inappropriate material are lessened considerably.
There are also security concerns with power outages and emergencies. Sanchez says that rack-mounted, uninterruptible power sources are commonly only sufficient to allow for server shutdown, not continuous use of the network. Schools typically provide power backup only for telecommunications systems. But backing up servers makes loss of data due to a power loss less of a problem. And, the drop in digital storage costs has made the idea of backing up a student’s entire academic career less far-fetched than it once would have been. Why would anyone bother with a CD, Sanchez asks, when server-based storage provides security and continuity between grades.

The big picture on small devices
While going to Wi-Fi-enabled laptops and PDAs may help to ease the problems of adding cable to older buildings, school technology administrators say infrastructure upgrades are useless without a comprehensive e-learning plan. That can mean anything from curricula changes in specific subjects to offering a high school diploma program solely via website. For example, introducing PDAs into a science lab means students can connect them to probes for testing things like the PH level of a river. At Littleton, Colorado schools, the district implemented a web-based learning program to help students with special circumstances complete their high school coursework. Using a well-known platform software called Blackboard K-12 Starter Edition, Littleton offers a wide selection of classes students access on-line or at a computer lab set up at the city’s Arapahoe Community College. Course content is provided by www.class.com, but the district could use its own class materials eventually. The program is tailored to help students transition either directly to jobs or to classes at Arapahoe. David Yaskin, a vice president with Washington D.C.-based Blackboard, says the program’s ability to expand instruction—using discussion forums, parental involvement, and additional resources—has been a boon to high schools.
Melinda Ness, Littleton’s coordinator for gifted and talented students, says the district hopes the pilot Blackboard program could be expanded to offer professional development courses for teachers, a common feature for other districts. Blackboard has been implemented in nearly 1,200 K-12 schools, many of which rely on the web for offering specialized classes for students in isolated locations. Students in some Alaskan districts, for example, can access Advanced Placement courses through Blackboard without resorting to the previous vogue in distance learning that relied on expensive and complicated teleconferencing facilities and instructor availability. And with Blackboard, like other web-based programs, assessment is instant and can be shared with a wider community of teachers, parents, administrators, and fellow students.
Tech transparency
“With Blackboard, we can track what students are doing, what assignments they are missing, and keep our finger on the pulse of where they are in the course,” Ness says. While parents haven’t been provided access to the site yet, the Littleton district’s own website allows them to see their student’s grades.
Although Littleton helped pay for its program by partnering with the community college, schools can apply for a grant for such initiatives through the U.S. Department of Education’s Star Schools program, begun in 2000. Star Schools, which requires a matching funds commitment from the schools, encourages schools to develop distance learning programs and offers funding for equipment, facilities, coursework, and support staff (see www.ed.gov).
Technology consultants and administrators almost uniformly point to so-called smartphones as the next wave in education. Like Palm’s Treo and other such devices, smartphones would allow students total connectivity while combining nearly every function they might use: phone, e-mail, and the Internet. Some school administrators already rely on smartphones to augment their work. If a principal catches a student wandering the halls during class, a quick name check on a smartphone—one that is Internet-enabled and connected to the school’s student database—could pull up the student’s photograph, class schedule, tardiness record, and parent’s e-mail address. Cutting class now has its digital risks.
