Clarksville, TN – Austin Peay State University (APSU) chemistry professor Dr. Leslie Hiatt spent some of the summer transforming a scrapped glass door into a learning tool for students forced to take online classes during the COVID-19 Coronavirus pandemic.
She turned the glass door – donated by Nashville’s Flow Construction – into a light board, a teaching tool she uses to make YouTube videos to help connect her online students to the classroom.
“This is one more tool that makes it so that they’re able to conceptually understand the chemistry,” Hiatt said. “I knew the challenges (of learning during the pandemic) – just getting used to technology was going to be hard for students – so I wanted to do everything I could to make it easier for them.”
Hiatt needed about 20 hours to turn the glass door into a light board. She turned the door on its side, lined it with high-luminosity LED lights and bracketed it onto a homemade wooden stand. Two holes remain where the door’s handle used to be, but the resulting light board helps Hiatt craft compelling videos to help her students learn chemistry.
The lights work with the pens to deliver a vibrancy to the lessons and allow online students to see Hiatt’s face as she delivers the lecture (instead of seeing her back while she writes on a white board).
“I want them to have an equivalent experience with previous years, but watching me via Zoom is not the same as having me in the room with them,” Hiatt said.
Hiatt has made more than 30 videos this semester, mostly for her general chemistry students. She followed APSU Distance Education’s advice and tries to keep the videos short, between 5 and 10 minutes.
“I think it’s working, and I feel like the students are getting in there, they’re doing good,” she said. “They’ve all had very good attitudes about it. They’re all working hard.”
‘Feel better about solving the problem’
Hiatt likes that she can look into the camera and point at the problem as she works through it.
“The students can see what I’m gesturing toward, how it fits in the equation and, hopefully, feel better about solving the problem,” she said.
She edits the recordings to add graphics and to flip the image so the students can read her writing (instead of the mirrored way it would show up without the edit).
The videos are supplemental to her live classes, which have a mix of in-person and online students each day. During the live sessions, she delivers lessons at a white board that online students watch on Zoom.
“They have to watch the lecture videos before they get to class, then they can ask questions while I’m doing stuff on the board,” she said. It’s a more real-time interaction, and they’ve already had time to process concepts, the math, what they need to learn.”

Inspiration for Hiatt’s Light Board
Hiatt first thought to build a light board for her students while honing her statistics knowledge for a paper she’s preparing for the Journal of Chemical Education.
“They asked me to do something called a Bonferroni Correction, and I had no idea what that was,” she said. “I found this really awesome video where the instructor was using a light board.
“In addition to learning about the statistics, the board made it easier for me to learn,” Hiatt added. “I thought maybe this would make it easier for the students to learn chemistry.”
You can see the video that inspired Hiatt here.
“As you can tell (in the above linked video), they have very professional lighting and a cleaner board, but I am happy with our much cheaper setup,” Hiatt said. “I think I have less than $200 in the project.”
Most of the cost is for the extruded aluminum heat sink frame around the light board, she said.
She already had some of the pieces for the board – such as a light her husband had – but she needed to buy the LED lights and extruded aluminum.
Hiatt plans to improve the lighting and sound of her videos, such as upgrading the wireless mic she already had at her house.
She plans to use the videos in her general chemistry classes all semester then expanding them to upper division classes starting next semester. She probably will continue the videos even after the pandemic passes.
The Journal of Chemical Education has accepted for publication the article Hiatt worked on with Dr. Anuradha Pathiranage and two students, Parth Patel (a May 2020 graduate) and Kristofer Conrad (a current APSU student), with statistics help from Dr. Sumen Sen. You can see the paper they recently published here.
