Augmented reality can be a powerful learning tool

What do a skillet, a grand piano and a computer have in common? They are all types of tools, of course. Sitting idly, they just take up space. But a skillet in the hands of Julia Child or Wolfgang Puck becomes a vehicle for delicious meals. A piano played by Rachmaninoff or Elton John can provide beautiful music. A computer in the hands of you and your students can lead to adventures and learning opportunities never before possible.

Using a mobile device, augmented reality (AR) superimposes computer-generated images, videos and animation onto the real world. I like to think of AR as another tool for enhancing curricula and inspiring creativity. Yes, it can be engaging. Pointing your mobile device at an object that then comes to life can be downright enthralling. But if it does not support an educationally sound lesson or prompt young students to create their own original and thought-provoking auras, then I’m not interested.

There are many reasons to incorporate AR into classrooms. As AR is catching on, more content is being developed in all subject areas and for all grade levels. Large organizations, such as NASA and National Geographic, are adding value to their already robust educational resources with well-documented explorations and thought-provoking activities. Also, teachers and students are taking advantage of easy-to-use cameras and apps to create their own customized auras.

An aura consists of a trigger and an overlay. The trigger is what your mobile device is pointed at. It can be a two-dimensional image or a three-dimensional object. An overlay can be a video, still image, text or animation that is visible when your device is pointed at the trigger. Many people, not sure of what AR is, light up with recognition when told that Pokemon Go is an example.

Although AR has been around for a while, 2017 may be the year that promising content will raise awareness of the possibilities in classrooms. In The International Business Times article “The next big thing in tech: Why augmented reality will dominate 2017,” David Gilbert provides evidence that AR will improve everyday tasks and help students with activities such as learning to code.

The following examples demonstrate three AR efforts that will impact the way we learn about the world.  

A corporation-supported STEM initiative
Many large organizations are committing resources to the development of AR apps that go beyond games and entertainment. In January, the New York Times announced its new app T Brand Studio AR, which is free in the Apple and Google Play stores.

Outthink Hidden was inspired by the movie “Hidden Figures” about African-American women working at NASA in the 1960s, but includes a far-reaching collection of “unsung heroes of innovation in STEM fields.”

An example is Abraham Nemeth, a blind mathematician who developed a Braille-based numerical writing system to give the visually impaired a way to participate in the field of mathematics. The claim is that “overlooked heroes from technology’s early days inspire tomorrow’s STEM leaders.” Download the app, then visit IBM.com/hiddenfigures to reveal photos, video and audio content. You can also visit over 150 statues, monuments and geofenced locations around the United States and learn about the individuals whom they honor.

A way to add experiential learning to literature
Traditional books, with hard or soft covers and pages to turn, can include target images prompting experiences related to the story. The Fantastic Flying Books of Mr. Morris Lessmore by William Joyce began as a book, was produced as an Academy Award winning short film and, with a free app, explodes off the page with enchanting, action-packed images, animation and sound effects. It is a story of a man who loves books, and the books that love him back. With so many variants on the way the story is told, the experience will appeal to multiple learning styles and, hopefully, entice and engage young readers, encouraging their own love of reading.

For older children and adults, bestsellers like A Tale for the Time Being by Ruth Ozeki offer media-rich enhancements, such as innovative book trailers and author commentaries. In a December 2016 article, Christian Howard, a scholar of contemporary literature, used the term “hybrid literature” to describe what he refers to as a “pioneering work in terms of experimental publication.” A Tale for the Time Being’s paperback cover is interactive, transformed into a 15-second animation using a Blippar AR app. Other authors and publishers are adding AR features to appeal to younger, technology-savvy readers.

Exploring scientific concepts with AR
Daqri’s Human Body and The Heart apps transform printed black-and-white coloring book type documents into animated anatomy demonstrations. You can explore the circulatory, lymphatic, and skeletal systems. You will see and hear the heart beating and can click on a selection of words including veins, right and left atrium, ventricle and valves, and the parts of the heat will be highlighted.

With Elements, another Daqri product, black-and-white printouts, folded into cubes, represent 26 elements. Examined with the AR app, “CU” becomes copper and “AU” turns into a shiny gold cube. The elements can be pushed together to form chemical reactions. Students use previous knowledge, and some trial and error, to create the chemical reactions, and their efforts result in animated and colorful responses. Hydrogen and oxygen become water, and chlorine and sodium turn into sodium chloride, or salt.

Scientific experiments are often too dangerous or difficult to perform in classrooms. The iScience: Elements, Forces and Explosive Experiments! is part of a series from Carlton Books, and another example of bringing traditional books to life with photographs, diagrams and illustrations that are triggers for AR. It covers scientific principles, such as sound waves, gravity, nuclear fission and reactants. With the AR app, you can split an atom in the palm of your hand or experiment with static electricity, complete with realistic animation and sound effects.

AR and children’s learning
While fascinated and intrigued by these new realities, I also have questions. How does this hyper reality impact student learning? Will it inhibit or inspire creativity? Some AR apps merely display content in a different format, while other AR apps provide robust, interactive and realistic experiences that would not otherwise be possible in a classroom. As with any technology, teachers need to decide what will work best with their students. Many teachers have already seen the excitement in their students’ eyes as they make books come alive, meet inspiring people, split atoms and let their imaginations run wild.

Maureen Brown Yoder, Ed.D., is a professor of educational technology at Lesley University in Cambridge, Massachusetts. A former classroom teacher, she currently works with inservice educators and teaches an online course on emerging technologies. She coined the term electronic constructivism and has written extensively on how to thoughtfully and creatively integrate emerging technologies into existing curricula.
