的Lightboard
的Lightboard from 教学技术 is a tool that can be used to create written or visual demonstrations for instructional videos. It functions like a see-through whiteboard; you write on one 一边 of it, and a camera records you from the other 一边. 的Lightboard is a large piece of glass enclosed in a frame that has LEDs embedded into it. The LEDs illuminate the writing which makes it stand out and look like it’s floating.
One of the main uses of the Lightboard is to demonstrate complicated material, such as a mathematical formula or diagram. The presenter can write or draw as they explain the content, providing helpful visuals that can improve understanding.
视频的优势
观看者可以暂停, 快进, 倒带视频, which gives them the control to learn at their own pace. These unique functionalities are an advantage that video has over live in-class instruction. Instructor-created videos are also personal; the presenter speaks and looks directly into the camera, simulating a one-on-one conversation. This presence increases engagement as the viewer can connect with the material and instructor more deeply.
了学习
Recorded lectures with the Lightboard can be helpful in 了学习. In 了学习, students receive instruction out一边 of the classroom, such as through 酒井法子. Class time is then reserved for discussion or activities in which students apply concepts and engage with the subject matter. Students can watch Lightboard videos of instructional content out一边 of class, 开放上课时间.

设计
的Lightboard is designed with the following components:
- 玻璃: 72″x36”x0.25″回火星.
- Frame & led灯: Grooves within the frame hold the glass and LED 带s. Power for the LEDs exits the bottom of the frame.
- 腿: The design, called a “theater” or “scene” jack, prevents the Lightboard from tipping over.
- 锁定脚轮: Installed on the bottom of the legs to add mobility.
- 支持梁: 连接腿以保持稳定.
- 沙袋: Placed on the feet to increase stability.
记录设置
Lightboard videos are created with the following equipment:
- 相机
- 照明
- 麦克风
- 黑色背景
- 霓虹灯窗户彩笔
To set up, the presenter stands behind the Lightboard. The camera is placed in 前面 and records them through the glass, as well as their writing. Lights are placed behind the Lightboard and pointed toward the presenter to illuminate them. We recommend placing a microphone behind the board to capture audio, as built-in camera mics are low quality and sound doesn’t travel through the glass well. The whole setup is a few feet in 前面 of a black background, which helps the presenter and writing stand out.
项目背景
The iTech Lightboard project was inspired by Dr. Katrina Hay, the first person at 欧洲杯足彩竞猜 to produce a Lightboard video. Dr. Hay built her own homemade Lightboard to create videos for her physics classes, 哪些对她的学生很有帮助. 想了解更多关于Dr. 海氏光板，去拜访她 教师聚焦页面.
在了解了这个工具之后, iTech applied for and received a grant from the Northwest Academic and Computing Consortium (NWACC) to create their own Lightboard. 看到 Lightboard建设 我们的过程的博客页面.
成本 & 材料
Our goal was to construct a low-cost (<$500) Lightboard that instructors can use as a model to create their own. The piece that put us over our goal was the see-through material for the writing. We tried to use an acrylic sheet (plexiglass), but the LEDs illuminated dust and inclusions within the material, which made it foggy and hard to see through. For clarity and quality, we went with Starphire glass. We hope that our design can be used an economical option for other institutions, as pre-built Lightboards are thousands of dollars.
