单选题 Most Hong Kong students aged 12 to 25 spend less than an hour a week studying online. However, it is claimed that e-learning (网上学习) may not be as popular among teenagers as commonly supposed.
In a survey by the Boys' and Girls' Clubs Association, 55% of 785 young people in Hong Kong said they did not like e-learning.
"E-learning is not a very good system because it is so troublesome (麻烦的)," said Patrick, 17-year-old, recalling how his online homework disappeared because of a technical problem.
Patrick also said some classmates give their account numbers and passwords (密码) to others so they could help them finish their online homework.
Self-discipline (自律) is also necessary. In the survey, 34.3% of the teenagers said lack of self-discipline made it difficult for them to learn more from the Internet.
But the teenagers also discovered some advantages in e-learning.
About 41 percent of the teenagers said they work together with other Internet users in order to discuss their problems.
Registered social worker Yuen Hin-sing said the effectiveness of e-learning is still not yet well supported by research data.
He called for more resources to study the effectiveness of online learning.
