Video tutorials in the style made famous by Sal Khan of the Khan Academy changed the face of education, empowering anywhere, anytime learning. However, they were Tutorials 1.0. We now have Tutorials 2.0. The LightBoard has arrived.
A Giant Leap Forward to More “Human” Online Learning
This next stage of evolution of tutorials allows students to get an enhanced experience with a more personal connection between the student and the teacher. Students no longer view only writing with a disembodied voice. They now get to see their teacher, complete with facial expressions, gestures and all the “human” things that make person-to-person explanations appealing. While nothing can replace a one-to-one, face-to-face explanation, this is better than anything in the past.
This type of tutorial is simple to make; any teacher who can stand at a board, write with a standard marker and explain a concept can now make tutorials—no digital pens and touch-enabled devices needed, and almost no technical knowledge required.
Video of Patrick Dare, a Mathematics teacher at Saint Stephen’s College, explaining some theory in a video tutorial created using the LightBoard:
That’s because the LightBoard is a sheet of glass flooded internally with light. The teacher stands at the “board” and writes with colored markers as a camera records the tutorial.
Creating the LightBoard Environment
I initially heard about this concept at a conference, and then developed the board in stages:
1. Research–There is plenty of information on the internet. The information provided by Michael Peshkin from Northwestern University at lightboard.info is really valuable. It was our guide. He provides all the information you will need, from materials and design through to lighting and tips for use.
2. Materials and cost–We then took the design information and built a list of materials to estimate costs:
- The “extras”–things needed to support the recording of the LightBoard–were relatively easy to source. Their cost was a few hundred dollars. We purchased LED strips for the top and bottom of the board, LED studio lighting, a studio microphone, black material to line the walls of the recording area and more. All are available online. Our school already had a suitable video camera that accepted an external microphone.
- The LightBoard itself required more effort. We decided to make our board about the size of a 65-inch television. However, a piece of glass of that size required dealing with a glass specialist. After a bit of searching, we found a company that was happy to take the design information from lightboard.info to supply the special formula glass, build a custom stand, mount the glass on the stand, and add metal channels at the top and bottom of the board through which we could thread the LED strips needed to flood the glass with light. This process from start to finish took several weeks as it was a custom build, and was a new experience for both the glass supply company and my school. The sheet of glass is mounted professionally on a stable custom made aluminium frame, and the cost was a few thousand dollars.
- The recording area needs to be in a separate room. A LightBoard is not something that can be moved from room to room easily, and equipment (lighting, microphones, video camera, a black backdrop, curtains etc.) needs to be positioned optimally and then left in place. Finding a spare room may be a problem for some. Luckily, we have been building an organization-wide online learning environment for over five years and filming tutorials by teachers in some form was always on the agenda.
