E-Mail in the Classroom Workplace 
E-mail usage creates special concerns in education, and teachers must learn how to make e-mail a more effective tool. Students must be taught how to use e-mail for purposes other than informal communication and to evaluate sources of information gathered through correspondence. Although e-mail presents problems in how and what students learn, it also can foster international learning experiences, provide some students with a clearer method of expressing their ideas, and increase collaboration.
