Shilpa stands in front of a mountain range, arms extended. A few seconds later, she’s transported to a city street. Look again and she’s swimming in the ocean. Finally, she’s floating through outer space.
These rapid trips around the universe are happening thanks to the magic of green screen technology, and to take them, Shilpa never once left her classroom in Nashville.
Green screen technology (also known as chroma keying) offers so many engaging opportunities for students to learn. It’s pretty easy to do, it can be done on a very low budget, it works in lots of subject areas and grade levels, and it’s even possible while teaching remotely. In my most recent podcast interview (listen or read the transcript above), I talked with teacher educator Justine Bruyère about the why and the how of green screen videos.
A solid green screen is placed behind the subject of the video, which in many cases is a person. Once the initial filming has been done, special software allows the video editor to replace everything that appears green on the video with a still image or another video.
This video explains the process:
Far from being just a cool novelty, green screen projects have the potential to give students deep, creative learning experiences. Bruyère points out a few key characteristics that make projects that use this technology so special:
For any green screen project, the following components are needed:
Because many of us are currently teaching in remote or hybrid situations, we’ll look at two ways to do this: at home with limited space and little to no budget, or at school with a little more space and slightly bigger budget.
At school, you’ll likely be able to give students access to devices that already have the green screen app loaded, so students will be able to record and edit their videos themselves.
As for the screen, you can still use the green paper option, or look for green tablecloths from a dollar store. If you have a little more money to spend, you could get something designed specifically for this purpose. This backdrop can be hung quickly with the included clips, then taken down when not in use:
If you have space to set up a green screen studio or area, you might want to spring for a full setup like this one that includes a screen, stand, and lights:
When Bruyère conducts a green screen project with students, the project loosely follows these three phases:
Start by modeling use of the green screen app for students. Bruyère will typically create a low-stakes video with students, where she models both how to use the app and her creative process: how the concept is developed, what happens if she makes mistakes, and how she makes improvements and revisions. Because she goes back to the video several times to make changes and improvements, this phase lasts several days. “Just like in a writer’s workshop model,” Bruyère says. “I consider the green screen a form of authoring, a form of writing.”
Students now begin working on their own projects. This process will be time-consuming and messy by design, and to someone passing by your classroom, it may look like things are a little out of control. But this ‘productive struggle,’ as Bruyère calls it, is necessary.
“Trust that mess,” she says. “they’re striving. They’re learning. They’re talking to one another, overcoming. And that is just such a beautiful thing because when a teacher dives in, when we solve the problem, we are taking away all the learning from the students. We’re robbing them of that valuable learning that they can transfer to other domains in the future.”
As students complete their projects, they begin to grow in their understanding of the technology and its possibilities. As you offer opportunities for subsequent projects, you can also share ideas for growth, ways students can stretch into more advanced skills:
The possibilities for projects are extensive and reach across many content areas. Here are just a few for social studies, science, math, and ELA:
At a time when actual travel has become a near impossibility, green screens offer a way for us and our students to keep exploring the world, answering big questions, and stretching ourselves creatively. Consider making them an option for your next classroom project and see what happens.
