Remember the days of students sitting in grid-like classroom rows with a teacher sitting behind a desk glued to a laptop screen? Those days are going, going, soon to be gone, said Jason Meyer, senior product manager, Epson America. So what’s next?
“Moveable furniture, multiple monitors, document cameras, and interactive projectors—that’s what the future classroom looks like,” he said. “In other words, it’s about ‘active learning,’ introduced as a collaborative learning space promoting both creativity and critical thinking, with an aim to provide equal visual and auditory accessibility for students, regardless of where they are sitting in the classroom. As the idea continues to grow in popularity and expand in capabilities, the need for collaboration-enabling technology will be crucial.”

With wireless device connectivity, students and teachers are already using tablet devices in the classroom, Meyer added. “With Epson education presentation displays, students can also project content from their devices onto entire walls and surfaces, and annotate on the wall in real time using their fingers with BrightLink devices. Teachers can see and display up to four devices simultaneously from a maximum of 50 connected student devices, or easily compare students’ work side-by-side for an engaging, collaborative learning experience. As the technology landscape develops, whether its high-speed networks, 3D printing, or high-resolution visualization, so will classrooms.”
When the term “active learning” was coined in the mid-1990s, it was to drive more advanced critical thinking through enhanced engagement, noted Michael DiBella, director of product marketing, Kramer.
“What is interesting is how drastically students have altered how they engage with content and each other,” he said. “Now it’s IM, social media, video, etc. So the ‘what’s next’ is integrating collaboration, wireless connectivity, and IoT into the room for all to use, not just the teacher. Rooms need to support how students communicate with each other for teachers to be able to blend those behaviors into their curriculum.”
When primitive digital whiteboards first entered the education space, they were used primarily to display content from the web, offering little opportunity for interaction with students, added Pippa Edelen, director of worldwide PR and social media, InFocus.
“Now, as capacitive touchscreens, wireless casting ability, and faster processing are available on these devices, teachers can use them to have students collaborate on their work, create diagrams, and perform other work on a touchscreen and interact with rich content such as videos and games,” she explained. “As these advancements continue, we’ll see teachers being able to incorporate more interactive elements into their lessons.”
Talk Before Action
Active learning is an approach, a pedagogy, and not, first and foremost, a type of room or a type of technology, noted Gina Sansivero, director of business development, education, FSR.
“The methodology has to be discussed during room planning, and not as a result of room planning or after the plan has been implemented and the technology and furniture installed,” she said. “The reevaluation of both existing and new spaces should start prior to the room design by understanding the teaching style most likely to be used in that room.”
Points to be discussed early on include goals of the particular classroom(s), as well as department and school goals. “Then you can bring the whole team together, including designers, integrators, technology managers, instructors, instructional designers or trainers, administrators, and, if possible, student advisors,” Sansivero explained. “Optimal usage of classroom technologies and increased successful student outcomes are reliant on well designed spaces, intuitive equipment, minimal training, and a complete overhaul of traditional pedagogy. Instructors who are entrenched in traditional teaching methods will not utilize modern, technology-rich learning spaces in the way they were designed, and this could result in awkward and ineffective spaces.”

Going the Distance
Distance learning continues to grow as educational facilities adopt videoconferencing as an important tool for their programs, Edelen said. “As it’s become easier to use and more accessible, educators are seeing the value of videoconferencing for working with students and teaching from a distance. With more videoconferencing for online lessons in place of static online materials like webcasts and recorded PowerPoints, students and teachers who are in online environments can interact the way they would in a true classroom. This isn’t standard for distance learning just yet, but we think we will see improvement as it becomes more widespread, bringing the digital learning space up to speed with what happens in face-to-face learning environments.”
Distance learning really needs to be broken into two groups, K-12 and higher ed, DiBella advised. “K-12 is tricky. You’re primarily leaning on tax dollars, and there is a greater premium to get a student into a classroom. Whereas higher ed values the ability to drive additional revenue by reaching students who are remote. They also use that as a value-add for students who may just want to log into a class from their dorm. I think you’ll definitely see greater adoption here in higher ed for that reason.”
For AV, IT, and infrastructure support professionals, there are some fundamental technology considerations when designing a distance learning program, Sansivero said. These include a school’s overall definition of and requirements for e-learning and how students will retrieve independent study materials from the school site and submit projects via email.
|Figuring out how to integrate collaboration, wireless connectivity, and IoT into a classroom, and making sure everyone uses the technology is key. “Rooms need to support how students communicate with each other for teachers to be able to blend those behaviors into their curriculum,” said Kramer’s Michael DiBella.|
“Will it be a combination of independent work and collaborative activities?” she asked. “Teachers and administrators may have to develop lesson plans, lectures, and projects in advance for remote learning; their buy-in for this is paramount to successful e-learning/distance learning programs. Does the school’s technology infrastructure support the previously defined continuity of learning program? Does it have the bandwidth and supporting software to be able to allow for downloadable content, videoconferencing/Skype sessions, lecture capture and retrieval, and digital communications?”
And finally, Sansivero advised determining the technological demographic of the student body and educators. “What percentage of students and teachers have internet access at home?” she asked. “How many have personal computers or connected devices? And are there any special technology requirements for disabled K-12 students or students under IEP? There will be tech related questions, and someone has to field those questions. Will you set up a technology support hotline during school hours that can route to your IT staff?”
The bottom line is that the technology in active-learning classrooms will continue to evolve, Sansivero concluded. “Specifically, collaboration systems and software are increasingly being used to support student and instructor cooperation and content sharing. Active learning rooms, as we seem to define them, have more fixed installations that typically result in fewer student seats per square footage. We are seeing a lot of schools redefining active learning spaces by allowing for more flexibility in movement around the room, and therefore the potential for more seats than a fixed install active learning room. In this way, wireless sharing has become a convenient technology for student collaboration. Access to power, however, is usually a challenge in these rooms and has to be addressed critically and creatively.”

The Security Issue
Cybersecurity issues don’t stop at the classroom door. In fact, as more technology is brought into a classroom, it’s natural for educational facilities to be concerned about the security of the equipment and the safety of its users, said Pippa Edelen of InFocus. “Schools are preparing for this with high encryption, the latest software and updates, and secure systems for wireless sharing.”
According to Educause, information security is the number-one issue for higher ed, Michael DiBella of Kramer shared. “Obviously, the very public data breaches in top universities are driving national attention,” he said. “It makes sense, too; a school is comprised of people who have to depend on mobile technology.”
Schools need to bring in thousands of kids, each with two or three devices, DiBella noted. “So with threats like phishing, and identity and access management, and with so many devices being networked together, you can see all these vulnerabilities to data breaches.”
Add in the need to invest in room technologies to drive enrollment to hundreds of classrooms, the library, student center, and other meeting spaces, and it becomes a huge challenge to keep up with the backend infrastructure to secure the network, he concluded. “To add further complexity to this issue, most engineering classes teach students how to hack and packet sniff.”
