How will future technology change the classroom?

To see the future of technology in the classroom -- and how it will change the way classes look -- we should probably start with college. Although we can't predict how technology will change, we can make some assumptions about how it will trickle down. Of course, university students are now almost uniformly armed with laptops. But they also often work with Learning Management Systems like Blackboard to post papers, receive instructions or discuss assignments or lectures. This is already starting to show up in lower grades; not just to monitor school work, but to allow parents to keep up and keep tabs on students' grades, homework and progress.

This speaks to a larger trend that technology might lead to in the future. Customizing the student's learning experience has become a hot (and debated) topic. Chris Dede and John Richards are Harvard University professors who propose a digital teaching platform called Time to Know that allows teachers to formulate large and small group learning, as well as individual education. They envision a classroom where each student has a computer, but the teacher can press a button to make all devices freeze, capturing a large group's attention. Beyond that, the teachers would use the broader big-group lessons to let each child find an individual understanding of how that lesson impacts them, personally [source: Dede and Richards]. But how would that occur?

As Dede and Richards point out, our classrooms don't lack content. With the Internet and the technology that lets us connect to resources around the world, what teachers now need is a system to assess what content is going to be most valuable to their class. These digital teaching platforms will have assessments that will theoretically help teachers determine a curriculum that's best for their community, classroom and even each individual student, in real time.

This idea of customization through digital teaching platforms is interesting, but let's consider some of the actual tools that might be used in the future classroom -- as well as some warnings about how technology might impact education negatively.

There are some pretty impressive ideas about how technology will begin trickling into our classrooms. And we're not just talking about a laptop for every kid. Consider a biometric technology that can measure a kid's breathing, facial expression -- even how fast they're typing -- to let teachers know how they're reacting to lessons or the learning environment.

There's also been a fair amount of attention to giving augmented reality glasses to kids in classrooms. The glasses act as a screen that projects information or images on them, supplementing, say, a book or map. Even better, augmented reality glasses could provide a video of the teacher giving instructions to each kid at a time.

But increasingly, there have been concerns about what technology in the classroom might take away from education. For one, there's the concern that technology in the classroom has had no real impact on student achievement or test scores [source: Richtel]. There's the fear that instead of spending money on research that would lead to a better understanding of learning, districts and schools will be forced to upgrade technology with little idea of how it's best used or if it's being implemented at the expense of basic reading, writing and math skills. Even worse, that money would be drained from the pockets of teachers and education professionals.

With that comes the worry that teachers will become obsolete, and the classroom will become an entirely automated experience. Already there is a concern that dependence on technology allows students to have a lot more information at hand, but to collect it too easily. Having a broad, easily accessible wealth of knowledge might harm the deeper understanding that comes from a careful analytical research process [source: Hopkins].

Technology will no doubt play a large part in the education system -- whether you have the technology or not.

With talk of biometrics, customized digital content and holographic teachers, it's easy to be intimidated by how far technology in the classroom can go. But I can't help but wonder who will get access to this technology and which kids will still have to scrape by. While "The Classroom of the Future" sounds like it could contain a dazzling display of technology, I'm more concerned with the teachers of today who don't make what they deserve yet still have to buy supplies out of pocket and students who are left with antiquated textbooks and rundown schools.
