New Technologies and Education: Transparent Lightboard

Abstract

Birla Institute of Technology & Science, Pilani, conducts Work Integrated Learning Programmes (WILP) as a means of continuing education for employed professionals. WILP introduced the Transparent Lightboard in 2017 with the objective of enhancing student engagement. The “lightboard” is a transparent board that is placed between the instructor and the camera and enables the instructor to face the camera while delivering lectures. The instructor can note the key points, write equations, and draw relevant diagrams on the transparent whiteboard using a special neon marker. LEDs are placed along the edges of the “lightboard” such that it illuminates the board and makes the writing “pop out”, using a Physics principle called total internal reflection of light. The camera image is “flipped” using either a mirror or via technology, enabling instructors to make eye contact with students leading to a more engaging delivery. The lightboard makes it easy to demonstrate things and facilitates experiential learning. Initial feedback suggests that students like the enhanced level of interaction/ engagement with the instructor. Our study has found that there is a positive impact of the Lightboard on student engagement.
