G Andrew Page and Ragnar Purje on a new frontier for educators
The purpose of this article focuses on two questions: What is augmented reality or AR? How can educators leverage this emerging technology for deep and active learning to promote impactful positive learning outcomes?
What is Augmented Reality or AR?
AR combines the real and virtual worlds, the physical and the digital, it is 3-dimensional, and users can interact in real-time. One of the most popular examples of AR is the PokeMon Go interactive game, which featured cartoon characters in the real world. It was the fastest app to get to 500 million downloads to date.
Now, think back to when you were younger and the fascination of “Pop-up Books”. This 3-D experience was low-tech but provided a deeper level of engagement with the story. However, the “Pop-up Books” were static and the interaction was minimal. Now, imagine biology students examining and dissecting a 3-D human heart, or geography students learning the proximal relationships from a earth hologram. AR enhances the learning experience through the interactive environment and creative possibilities.
Learners as young as three and four years of age can use AR to view, manipulate, and enhance the learning experience with not only 3-D images but with interactive sound, movement, and more. Learners can experience a dynamic realm of multi-sensory images, witness relationship of cause and effect, and gain a deeper understanding of the world. This video provides creative examples of how AR can be used in education. https://www.youtube.com/watch?v=rm2skiMTUJ8
Augmented Reality or AR is an emerging technology that enhances the learning experience with applications in subjects such as STEAM (Science, Technology, Engineering, Art, Mathematics) as well as history and the humanities. Augmented Reality began to surface in 1950s with enhancing the cinematic experience to “draw the viewer into the onscreen activity by taking in all the senses in an effective manner” Carmigniani et al 2011, p.352).
AR and Education
AR can enhance the real world in real time by adding virtual objects such as a medical visualisation of the human body for an anatomy course, augmenting the visual acuity for learners with poor vision, and has grown to encompass all subjects. Simply reading about topics such as Geometry and Anatomy can help a learner become cognisant of a topic. AR allows for learners to see and manipulate 3-D solids (tetrahedron, icosahedron etc) or to perform a virtual dissection of the human body. The AR experience can be displayed through handheld devices such as a smartphone, a head mounted display (HMD), or even with an augmented reality headset. Here’s a example of me showing AR e-Book that was created by my wife’s students in Anchorage, Alaska. The goal of this collaboration between these first and fourth year e-book buddies was to create an augmented reality ABC book. The video demonstrates the 3-D nature of AR and shows a Puffin, a bird indigenous to the state of Alaska. Notice how camera lens is used to create the 3-D effect.

How Augmented Reality works
The next article will explore more details on HOW AR works and what tools educators can use to create engaging, active, 3-D lessons in their classroom. Future articles will explore AR Headsets and Hardware peripherals (Link: https://www.youtube.com/watch?time_continue=2&v=v7r_2fYsWn0 Time 0.48), free mobile augmented reality apps for iPhone and Android platforms (Link: https://www.youtube.com/watch?v=s0bt3G5ZAkY (Time 4:03), a case study of a school district that has implemented AR into the curriculum.
