TVA IT Lends A Hand To Students

  • Thursday, May 19, 2016
TVA IT employees teach Chattanooga elementary students how STEM skills can improve lives. The students’ final assignment? To 3D print and assemble a prosthetic hand to help a child in need. 

In Chattanooga, Orchard Knob Elementary fourth graders like Jaden Roberts, 11, could not wait for Chris Welch, TVA IT program manager, and his team to come back to the school to help teach STEM skills.

“On the first day we started, Jaden told me ‘I don’t like math’,” Mr. Welch said. Then Mr. Welch asked Jaden and the class, “Who likes video games?” and everyone raised their hands. Mr. Welch explained that video games were created with math and you use math when you play them.

“It was that ah-ha moment where you saw it in their eyes an abstract concept become real and fun,” Mr. Welch said. “We knew we had them.”

For the past few months Mr. Welch has been using 3D printing and virtual reality technology to teach math and engineering skills. “We started by printing cubes to calculate volume,” he said. “Then things expanded as the students quickly caught on.”  

Mr. Welch used virtual reality to explain architecture and design. The team also used circuit kits to teach electricity and electrical engineering. “One student [Raven Chapmen] even made a fan from the electrical parts because she said she was hot that day.” 

Everything was building up to the student’s final assignment in mechanical engineering—printing and assembling a real prosthetic hand.

The week of May 15, Mr. Welch and his students completed printing the prosthetic, which that will be used by a young child through the Enabling The Future charity based out of Atlanta.

“This was an amazing journey with the students,” Mr. Welch said. “At TVA our mission is to serve. I believe that we not only opened career doors for these young minds, at the end of the day, together we helped a child who literally needed a hand.”
