The Wild and Amazing World of Augmented Reality

The poster child for a cutting-edge classroom over the years has included computers (back in your mom’s school days), iPads (a surprisingly long time ago), 3D printing, Maker Space, and G Suite. By now, those have all been mainstreamed, with savvy parents asking, “What else do you offer?” In today’s world, “Augmented Reality” is the most popular ending to the sentence that begins, “My school actually has…” Called AR for short, the technology does exactly what the name suggests: It allows students to learn more about what they see.

Using reality inspired by their lesson plan, teachers expand—in fact, they supersize—lessons with motion, color, websites, audio, and other pieces that enrich students’ experience. When students unpack learning via AR, they want more and don’t want to leave. They also develop a willingness to solve complex math problems and understand deep concepts just
so they can see what else comes with augmented reality.

As an affordable boost to educational engagement, AR in theory takes students into Harry Potter’s world where school hallways are lined with interactive paintings. After downloading an Android or iOS AR app, students aim their phones at an image (called a “trigger”) and reveal deeper content layered on top of the physical world. The content can be a student’s discussion of a book they read or the inspiration behind their artwork. Unlike QR codes or other embedded link technologies, AR content is superimposed onto existing materials in the student’s own real-time environment.

How is AR Different From Virtual Reality?

Ask anyone about AR, and the usual answers will conflate it with Virtual Reality (VR), which is a wonderful education tool in its own right. But there are important distinctions between the two. Kathy Schrock, Adobe Education Leader, Google Certified Teacher, Sony Education Ambassador, Discovery Education STAR and a DEN Guru, and columnist for Discovery Education (just to name a few of her accolades) said it best:

“Augmented reality layers computer- generated enhancements on top of an existing reality to make it more meaningful through the ability to interact with it.”

“Virtual reality is a computergenerated simulation of real life… It immerses users by making them feel they are experiencing the simulated reality firsthand.”

How to Use AR

While AR isn’t difficult or expensive to use (especially when compared to 3D printing or makerspaces), it does require forethought and planning. You’ll need a smartphone or tablet with a back-facing camera, an augmented reality app (many free versions are available), a trigger image (you can create one yourself, probably for free), and an Internet connection. Then, scan the trigger image with a mobile device app and see what happens!

10 Ways to Use Augmented Reality in the Classroom

I collected the best ways to use AR in the classroom from colleagues and edtech websites (like Edutopia) to provide a good overview of the depth and breadth of education now being addressed with AR-infused projects:

Book Reviews: Students record themselves giving a brief review of a novel that they just finished, and then attach digital information to a book. Afterward, anyone can scan the cover of the book and instantly access the review.

Classroom Tour: Make a class picture image trigger a virtual tour of a classroom.

Faculty Photos: Display faculty photos so visitors can scan the image of an instructor and see it come to life with their background.

Homework Mini-Lessons: Students scan homework to reveal information that will help them solve a problem.

Lab Safety: Put triggers around a science laboratory that students can scan to learn safety procedures.

Parent Involvement: Record parents encouraging their child, and attach a trigger image to the child’s desk.

Requests: Trigger to a Google form to request time with the teacher, librarian, or other educator.

Sign Language Flashcards: Create flashcards that contain a video overlay showing how to sign a word or phrase.

Word Walls: Students record themselves defining vocabulary words. Classmates scan them to get definitions and sentences using the word.

Yearbooks: So many ways, just know AR will energize any yearbook.

AR is the next great disruptive force in education. If your goal is to create lifelong learners inspired by knowledge, AR, in its infancy, holds the seeds for meeting that goal.
