If you want to prepare for the future of educational technology, start by exploring the past. Look at the word “educate” and its Latin root educat; according to Merriam-Webster, the origin meant “led out.” If educate means to bring out rather than impose or give, how can audiovisual (AV) technologies help digitally savvy students make surprising connections or answer questions on their own? What are the AV trends that can help teachers draw insights from learners today and tomorrow?
There is no shortage of projectors, microphones, and lecture capture devices available to school districts, but there is a crop of new AV products designed with the mission to support more engaging and active learning environments. Here is a sample of case studies that illustrate how AV can turn K-12 spaces into student-driven hubs.
1 AV TECHNOLOGY FOR SOFT SKILLS AND DESIGN THINKING
“The Role of Education in Building Soft Skills,” a Wainhouse Research K-12 report from 2015, revealed that problem-solving and collaborative skills are the primary soft skills on which schools should be focusing in the next decade.
“Educators, parents, and students find that the benefits of a focus on collaboration are many, from encouraging active participation among learners to encouraging learners to take ownership of their education,” the Wainhouse Research analysts observed.
“Collaboration” and “creative problem-solving” are terms that are often overused and misunderstood, but deployed carefully they can complement rigorous K-12 pedagogies. According to the International Society of Technology in Education (ISTE), collaborative technologies are “applications that facilitate teamwork and collaboration between students and experts around the globe; for example, knowledge-sharing tools, videoconferencing, digital project spaces/sites, chats, and collaborative schedulers.”
As AI and automation seep into more of our daily tasks, it is creativity, emotional intelligence, and empathy that will give students and professionals the edge. Creating a framework for critical problem solving earlier rather than later is beneficial.
One example of a project that has sparked new ways of thinking in students is the 2018 collaboration between Riverview High School in New Brunswick, Canada, and Pheasey Park Farm Primary School in Birmingham, UK. Both schools, separated by a vast ocean and thousands of miles, worked closely together, as if they were in the very same room, thanks to the Nureva Span visual collaboration solution and the HDL300 audio conferencing system. In six sessions over three months, 12th grade students at Riverview High School and 4th grade students at Pheasey Park Farm Primary School jointly explored a profound question: “What does it mean to be human?” They exchanged ideas, hopes, and fears about how artificial intelligence and other technological innovations will impact their lives. According to Nureva, “the older students were brought together with the younger students to explore their divergent views when discussing these complex topics.”
Each learning space for the unique project is equipped with a 20-foot 2-inch wide Nureva Wall system, cloud-based Span visual collaboration software, and an HDL300 audio conferencing system. Combined, this enables students to share and develop their ideas together, as if they were in the same classroom. What’s more, Nureva stated that design thinking is what drives the collaboration, “providing a framework where participants identify problems and develop, test and refine solutions.”
The emphasis on soft skills doesn’t demote the importance of curriculum fundamentals like reading, writing, and arithmetic. New AV technologies, such as the ClickShare wireless presentation systems from Barco and wePresent, huddle systems from Mersive, Crestron, and Harman, and interactive displays from the likes of InFocus, Nureva, Google, Cisco, and Avocor, put more power in the hands of learners. Instructional designers and teachers are playing ever important roles as they design syllabi and curricula enriched with technology that puts school district learning objectives first.
2 IMMERSIVE, INTERACTIVE VIDEO INSPIRES CREATIVE SYNTHESIS
Reading about Paleolithic cave art is one thing, but touring it in 360-degree video, with the ability to pan, tilt, and zoom in on a brushstroke is another. The latest iterations of 360 video, interactive whiteboards with high-touch functions, and laser projectors are giving K-12 teachers and technology directors more and brighter ways to inspire and empower students.
At the Castleberry Independent School District (ISD) in Fort Worth, Texas, multi-touch interactive displays are supporting rigorous and engaging pedagogy. Containing seven campuses with three elementary schools, a middle school, a high school, an alternative school, and a learning center, Castleberry ISD is an educational leader that is committed to supporting “lifelong learning” in a diverse, changing world, according to the school. Advanced technology is integral to the school’s mission as it enables collaboration and interactivity. The school district’s IT department regularly evaluates its technology to ensure that it is meeting the highest standards set forth in the district’s technology vision. Most recently, this included replacing older whiteboards and failing projectors in the ISD’s three elementary schools with new BenQ RP653 Interactive Flat Panels (IFPs). The results have been compelling.
Jacob Bowser, IT operations manager for Castleberry ISD, explained that the new BenQ system is easy to use for both teachers and students. “When training our teachers around new technology, they do an incredible job of incorporating it into their classrooms,” he said in a release. “It becomes an integral part of their lessons, so it’s essential everything is always up and running.” With the RP653 IFPs, guesswork is eliminated. Additionally, the system’s 20-point multi-touch interface allows multiple students to work side by side at the 65-inch screen. Learners can simultaneously touch the screen with virtually no delay in response.
Tracie Bryant-Cravens, vice president of sales, state/local government and education, AVI-SPL, agrees that interactivity and multi-touch features are key AV trends in K-12 projects. “Interactive teaching and presentation systems are hot, as are 4K UHD interactive displays and active learning/makerspaces. We are seeing a, decline in projection in favor of high-resolution interactive displays placed throughout the classroom rather than at the front of the room. Makerspaces and active learning spaces are trending, with a focus on high-touch collaboration, meaning small groups huddled together leveraging technology with the teacher facilitating, aligning technology with their curriculum.”
Another inspiring example of interactive display technology in K-12 is in Beaverton, Oregon. Recipient of “Future Ready” and “Positive Change” grants, Beaver Acres Elementary School teacher Heather Hoxie is using one-to-one (1:1) devices and an interactive touch display to individualize class instruction. Hoxie replaced her classroom’s whiteboard with the InFocus JTouch Interactive Display. The display is bright enough to use at any time, even with all the classroom lights on. Each of her student’s individual devices is equipped with InFocus Lightcast software so they can wirelessly share or cast content to the JTouch for higher-level collaboration with no lag time or VGA cables.
Interactive display solutions like the Microsoft Surface Hub and Google Jamboard are popular on the enterprise level; in K-12, affordability and scale are critically important. Interactive whiteboards that are easy to use, offer cloud access, and have more budget-friendly price points appeal to modern school districts that may want to standardize.
While some AV integrators like Bryant-Cravens see interactive flat-panels on trend in K-12, the projection market has never been stronger. Just look at the new Optoma ZH420UST laser projector. This protean 1080p device incorporates a laser light source, 4,000 ANSI lumens, 100,000:1 contrast, and 0.25:1 ultra short-throw ratio. Warping adjustment and automatic edge blending are built in. When combined with an Optoma Projected Capacitive Touch (PCT) screen, multiple participants can interact with the content.

VR IN K-12
ClassVR Case Study: St Wilfrid’s C of E Academy (Blackburn, UK)
3 AGILE VIDEO MEETS LEARNERS ANYWHERE
From a school play to a band concert, video streaming is helping broader communities connect with and support more student activities. Family and friends who cannot attend in person can feel the pride of graduation or the excitement of a production of “The Music Man” with Facebook Live, YouTube, or Periscope via smartphones. At the heart of professional-grade streaming systems are recording, encoding, decoding, and multi-platform distribution solutions. While these systems used to be relatively costly, they are becoming more affordable, they offer more automated features, and they are coming in more compact chassis designs.
A smart video broadcast and streaming solution is literally making dreams come true at the Plum Borough School District in Pennsylvania. Plum Borough runs the biggest school fundraiser for the Make-A-Wish Foundation, due in large part to its energetic, student-produced annual telethon. Plum Senior High School students produce the telethon under the direction of TV Production teacher Rick Berrott; the broadcast reaches the broader Pittsburgh region via community access channels and the school district’s YouTube channel.
Last year, however, the school’s standard-definition (SD) video production equipment was failing, so Berrott needed a new solution. Working together with Jeff Waller and his team at the Production Consulting Group of Wexford, Pennsylvania, they implemented a NewTek TriCaster 460 to produce the telethon as well as morning announcements that are broadcast live every school day. A TriCaster Mini was also purchased for school board meetings and sports events. With three to four students available to produce each broadcast, Berrott says the TriCaster is easier to operate than their SD system since it allows them to quickly adjust their JVC ProHD cameras using the position icon. “The TriCaster is so much more powerful and also hands-on,” he said. “It’s not just a studio in a box, it’s like having a production team in a box.”
4 EMERGING TECHNOLOGIES FOR MEMORABLE K-12 EXPERIENCES
2018 is a banner year for artificial intelligence on the consumer level; some of the most notable offerings are Alexa, Echo, Invoke, and IBM Watson. Now there is Watson Assistant, a customizable voice assistant for potential to help classroom designers create systems that respond to individual commands or requirements for each room and/or instructor. They can also be automated and customized.
While AI is increasingly present in AV and classrooms, the broader adoption of Augmented Reality (AR), Virtual Reality (VR), Mixed Reality (MR), and Internet of Things (IoT) in K-12 is not quite there yet, according to AVISPL’s Tracie Bryant-Cravens. “Most of AR and VR is leveraged today in higher education.” She believes that gamification is the “first step” for K-12 and Virtual Reality.
“Augmented Reality is moving more quickly, thanks to tools like Amazon Echo. You used to have information at your fingertips—with Google, for example. But now you have information at your ‘lips.’ I used to have to look up my vocabulary words in the dictionary;now my eight-year-old daughter asks Alexa how to spell and define her vocabulary words.”
In England, however, there are already exciting use cases of VR in K-12 environments. As NewBay editor Michael Garwood reported from the ed tech trade event BETT2018, “One of the most prominent and busiest stands at the show belonged to AVANTIS—a specialist in educational technology for over 20 years—who was showcasing the benefits of its ClassVR solution.” At St Wilfrid’s Academy in Blackburn, UK, the ClassVR portal is enabling teachers to see students’ VR headsets in real time, and deliver and shape VR experiences collaboratively with groups. Since studies show that 90 percent of people remember what they experience at far higher rates than what they hear, read, or see, experiences can help transform learning, from immersing a student in the trenches of World War I to marching in Selma for civil rights. The possibilities are endless.
These “a-ha moments” have the potential to unfold in students’ minds long after the school year ends. After all, aren’t the most surprising discoveries the ones we make about ourselves?
5 INTERACTIVE PROJECTORS ENHANCE ACCESS TO ALL TECH
The mission of Parkland School District in Allentown, Pennsylvania, is to ensure that students are empowered with success strategies for lifelong learning. That’s why Robert Uhl, telecommunication specialist, has worked to fit eight of eleven schools with smart classrooms including Hitachi’s CP-TW2505 interactive projectors.
Parkland School District is made up of eleven schools including eight elementary schools, two middle schools and one high school and Uhl oversees the classroom and other AV equipment for the entire district. On top of the eight schools with smart classroom technology, Uhl also helps with the technology in the TV studios for the student-produced morning show and the digital signage used throughout the schools.
“We’ve been involved with Hitachi for well over a decade,” says Uhl. “Before the CPTW2505s, we had other Hitachi projectors tied into the Hitachi’s Starboard technology that we installed about ten years prior. The new projectors give us many more options with how it interacts with other technology. We often use Video Over IP in some classrooms for the morning shows, and also use the projector to watch cable networking throughout the day. We still use standard TVs in most classrooms, but all classrooms are smart.”
Uhl says that one of the best parts of the upgrade for teachers is that they get to utilize the entirety of their whiteboards again. “With the Starboard program we were using before, we had to mount it onto the whiteboard in the classroom, which took away a considerable amount of whiteboard space. Now, teachers are able to enjoy the benefits of an interactive projector while also utilizing their entire whiteboard space.”
Right now, Parkland School District has well over 200 Hitachi projectors including approximately 180 interactive and 30 standard projectors. This summer, Uhl is looking to complete the upgrade in the last three schools in the district.
