When it comes to learning material, many of us still think of two-dimensional content consisting of text, images, video and multimedia viewed on a screen or printed on paper. Among the many, there are a growing few who have started to see teaching and learning in 3D where materials are either made virtual or augmented to create far richer and immersive learning experiences. Increasingly, many governments and institutions around the world are making major investments in virtual reality (VR) and augmented reality (AR) technologies for education under the broader umbrella of artificial intelligence (AI). However, many of these investments remain isolated pilot projects which tease at what education could look like in the near future but likely won’t due to scalability.
Recently, I was invited to visit the Emerging Media Lab of the University of British Columbia in Canada to experience hands-on some of their AR and VR projects which tackled real world learning scenarios. In VR, the Stanley Park Geography VR Field Trip allowed me to walk through a popular public park in Vancouver and interact with various objects along the way. An interesting feature of this VR project was its use of 360-degree videos within the VR environment to augment the digital world with real-world immersive videos of Stanley Park. The AR project HoloBrain was no less impressive. Using a “HoloLens”, a mixed reality headset offering the unique ability to blend virtual 3D content with the real world, I was able to interact with a larger than life model of the human brain floating in the air in front of me. Using gesture and voice commands, I could access multiple views and layers of the brain to learn more about how it functioned. Although in awe at what technology can offer future learners, a sobering thought crossed my mind at this point about how this can be scaled up and sustained.
With consumer electronics getting cheaper by the day supplemented by the wide use of free and open source software (FOSS), experiencing AR and VR have become much more affordable. Growing access to high-end smart phones running FOSS operating systems and build it yourself VR equipment such as Google Cardboard promise, at least in theory, some AR and VR interactions in all future classrooms even in the developing world. However, just having access to technology which support immersive experiences doesn’t amount to much if the content is lacking. Therein lies the dilemma of technology-enhanced learning where AR and VR are no exceptions.
Arguably, creating AR and VR experiences is no mean feat. Even a small interactive experience can take teams of people months to perfect spending thousands of dollars. Yet many of these experiences can be categorized as tiny learning objects in the larger scheme of teaching and learning. For example, the interactive VR experience of the Stanley Park field trip could potentially be a sub unit of a geography or history course whereas the HoloBrain experience could be a subunit of a biology or medical course. Scaling up, it is almost unimaginable the amount of effort, time and money needed to create an entire course based on AR and VR using current technology; but what if AR and VR are looked upon as OER?
The Ljubljana OER action plan 2017 defines open educational resources (OER) as
“teaching, learning and research materials in any medium – digital or otherwise – that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation and redistribution by others with no or limited restrictions.”
Bound by the same principles, if AR and VR projects are released into the public domain or under an open license, governments, institutions, teachers and learners would be able to use, adapt and redistribute these immersive experiences to benefit their teaching and learning. Further, collaboration among AR and VR content creators will result in the development of more comprehensive content and new pedagogies which will propel the use of low cost AR and VR into the mainstream. This present drive towards VR and AR in education has provided us with a unique and historical opportunity to get it right the first time by promoting open practices among content creators from the outset. As proponents of all things open, we should capitalize on this trend to ensure a future where isolated projects, such as the HoloBrain from Canada, are developed into complete human anatomies freely used by thousands of teachers to inspire millions of learners forming the basis of a much wiser human race.
