来自加州尔湾学院(Irvine College)的学生苏丹·西良(Saira Sultan)说,她每周都向TutorVista的老师请教好几次英语和数学课上的问题,而老师们博学而友善。她说,最近她的英语课要求写一封商业信件,她把作业上传到网上,辅导老师会标出错误、纠正动词时态,调整段落格式,并将语句梳理通顺。这种一对一的编辑帮助她的英文写作更加清楚明白。
The drawback, she says, is that communicating via text chat 'takes a lot of time.' Mr. Swaminathan says TutorVista can provide audio-chat sessions if scheduled in advance.
她说,缺点是用文本聊天来沟通“很费时间”。斯瓦米纳坦说用户可在TutorVista上预约视频辅导课程。
As with in-person tutors, knowledge levels and teaching skills can be uneven. Stephanie Dobbs of Los Angeles says one InstaEDU tutor who responded to her daughter Sarah's request for calculus help 'didn't know the material at all.' But Sarah, who uses the site two to three times a week, says it has so many tutors that switching is easy, and the convenience outweighs any drawbacks.
然而,那些辅导老师的知识水平和教育技能常常良莠不齐。洛杉矶的斯蒂芬妮·多布斯(Stephanie Dobbs)说她女儿萨拉(Sarah)在InstaEDU上找到的微积分家教“根本不了解这块知识”。然而Sarah每周却要上这个网站两三次,她说更换老师很容易,使用这个网站利大于弊。
