学校和家庭的网上通信

　　　网上通信强调21世纪技能，自我导向学习，自已宣传、全球意识和学习者的思维能力。运用网上通信方法，学校帮助学生发展网络礼仪和计算机技能。另外，老师能通过自动电子邮件，官方网站和学习管理系统，经常向父母提供学校课程以及他们孩子的进展情况。这种通信同步或异步都可实现，提供了更大的时间弹性。

　　　利用网上通信，学习可能发生在传统课时之外，当学生们参加合作学习时，可以在网上论坛立即阅读和回复给同行职位关于实验、小组项目、论文研究和时事岗位等分配事宜。另外，网上通信可能连接各种各样的个人，给予学习者更多的他们所希望多样性的观点。

　　　然而，不是所有的父母、学生或者老师都有机会获得无线上网或数字通信技术可以参与网上交流，并且初步实现信息技术、硬件和软件的连接也可能很昂贵。此外，学校必须给网上环境和技术支持提供方向，以确保所有潜在的用户都愿意参加。作为通信活动的活跃参加者(例如讨论主持人等)，老师也需要花费额外的上网时间。另外，网上通信可能直接导致学生和父母对老师“任何时间”都要在线的不合理期待。………………

外文出处：The Predictive Effects of Online Communication onWell-Being among Chinese Adolescents，Haizhen Wang;Jinliang Wang Psychology 2011

Online communication emphasizes 21st century skills, self-directed learning, self-advocacy, global awareness, and thinking skills for learners. Utilizing online communication methods, schools help students develop Netiquette, and technical and computer skills. In addition, teachers can provide parents with frequent information about school programs and their children's progress through automated e-mails, official websites and learning management systems. This communication can be achieved either synchronously or asynchronously, providing greater time flexibility. 

With online communication, learning may occur outside traditional school hours as students participate in collaborative activities, like reading and responding to peer posts in online forums, experiments, group projects, research papers, and current events assignments. In addition, online communication can connect a wide range of individuals and increase the diversity of perspectives that learners are exposed to. 

However, not all parents, students, or teachers have access to unlimited internet access or the digital technology necessary to participate in online communication, and it may be costly to initially implement the information technology, hardware,and software.Furthermore, schools must provide orientation to the online environments and technical support to ensure that all potential users are ready to participate. Teachers will also need to spend additional time online as active participants in the communication activities (e.g. act as the moderators of discussions).In addition, the immediacy of online communication can lead to students and parents' unreasonable expectations that teachers be 'on-call' at all times.………………
