A
Medha Pappula, an eight-grader at Brambleton Middle School, is using her skill set to solve a problem — bullying. She recently earned an award from National Bullying Prevention Center (NBPC) for her anti-bullying efforts in software development and animation (动画).
Pappula 13, said she discovered that a classmate had experienced cyberbullying (网络欺凌), which was painful for her to learn about. “Even though I didn’t experience it, I wouldn’t wish that on anyone, even my worst enemy.” Pappula said.
Then she developed a program. “It takes a message, and then recognizes signs of bullying and gives a rating (评价) to the cyberbullying.” the teen said. “If the rating is high, the program can be used to carry out things like removing that message or reporting it.”
In addition to this program, the NBPC awarded Pappula for a three-minute animated video about Unity Day, which she created and shared on YouTube last October. Unity Day was started by the NBPC in 2011 to raise bullying awareness among school-age children. Schools encourage their students to wear orange on Unity Day, as it is a color that is connected with safety.
Pappula visited different websites to develop her animation skills several years ago. She spent more than a month creating her 2-D animated video using an animation software called Krita. The effort paid off, as nearly 6000 people have already viewed the “Unity Day” video on YouTube. Pappula hopes to continue to work with the NBPC and use her skills to lift those around her.
