按需定制的辅导只不过是正在发展的在线作业辅导产品的一小部分。举个例子,Khan Academy在提供教学视频的同时也提供交互式辅导课程。Chegg.com提供作业答案,而StudyBlue这样的众包网站则让学生可以分享讲义、笔记和学习卡片。
Some school districts pay New York City-based TutaPoint and other online-tutoring sites to provide free access to students; about 2,000 libraries let students use Tutor.com without cost. Free access to tutoring sites can help level the playing field for students from all income groups -- if they provide trained, qualified tutors, conduct background checks and safeguard users' security, says Nora Carr, president of the National School Public Relations Association, a professional group.
一些学区向总部位于纽约的TutaPoint和其他在线辅导网站支付费用,以便其学生能免费登录这些网站。约2,000家图书馆也供学生免费使用Tutor.com。专业组织全国学校公共关系协会(National School Public Relations Association)的主席诺拉·卡尔(Nora Carr)认为,这些举措可以帮助不同收入阶层的学生享受到更加平等的教育机会──前提是这些网站的辅导老师经过训练、具有职业资格,职业操守经过审查,并且网站能确保用户信息安全。
But the sites can also tilt the playing field in favor of kids with plenty of money for tutoring help, creating pressure for other students to have a tutor too. Parents should monitor kids' use of the sites and track fees, which 'can get very expensive very quickly,' says Ms. Carr, who is chief of staff of the Guilford County Schools in Greensboro, N.C.
