Nowadays, many students do homework with the help of the Internet like Andy. They search for information online, use apps or discuss through social networks like QQ and WeChat.
“It’s convenient.” Andy said. “You also learn by seeing how others work them out.”
“It also improves students’ abilities.” said John, another student. He said it’s true for new types of homework.
John’s Chinese teacher often asks students to give speeches on great authors. When it comes to John’s turn, he usually searches online, picks out certain stories and makes PowerPoint presentations.
“I’ve become skilled at finding information online and using Microsoft Office,” Wang said.
However, many students think this trend (趋势) also brings up problems. Some students just copy the answers online without thinking. They become lazy.
A head teacher in Andy and John’s school said that knowing how to use the Internet is important. The key is to have good self-control.
“No matter how difficult the problem is, think about it independently (独立地) first,” the teacher said. “Be sure to understand the reasons behind the answers, or you won’t make progress. If you don’t have confidence about your self-control, ask your parents for help.”
