B
Have you ever paid attention to your school's security guards or dining hall staff(职员)? Would you say "good morning" to your school's cleaners? For high school student Ding Jiacheng，it's a problem that many students ignore(忽视)the important jobs done by these non-teaching workers. He wanted to make a change.
The boy from Hangzhou Entel Foreign Language School，together with several other students，worked on a project called "The invisible(隐身的)are significant". They hoped more students would see and respect the "invisible" staff on campus. The project won a prize at China Thinks Big，a competition held by Harvard University and Tsinghua University to encourage teenagers to study social issues.
"My team members and I sent questionnaires to 158 students，" said Ding. "In one question，56 per cent of the students said they would greet those non-teaching workers，while only 17 per cent strongly believe that every student should do so."
The team also observed interactions(互动)between students and workers. "When most students follow the rules of their teachers，one-third of the students go against the rules of the dormitory attendants(宿舍管理员)，" said Ding. "It shows that students treat non-teaching staff differently from teaching staff."
The main reason，according to Ding，is that students know little about the work done by non-teaching staff. They also have few chances to communicate with them. Therefore，Ding's team shot videos to show staff working around campus. They also held a basketball match between students and non-teaching staff to increase their interaction.
"We've also made a series of stickers，" said Ding. "We hope these cute images will help young people like the non-teaching staff more."
"The activity helped me understand that we can all make a positive impact(积极影响)through our creative ideas，" said Ding.
