Internet tools associated with Web 2.0 such as wikis, blogs, and video podcasts are increasingly available in elementary classrooms. ("Web 2.0" is a vaguely defined, folk-tech term that means, roughly, the Internet and all software and devices, constantly improving, that strive to exploit it in creative and useful ways.) Today, elementary students can communicate with other young people on the other side of the globe in a matter of seconds. How can teachers prepare themselves, and their students, to make good use of these new powerful tools of communication? eMINTS (Enhancing Missouri's Instructional Networked Teaching Strategies) is a national center at the University of Missouri that promotes quality teaching with technology. The eMINTS "pedagogical approach allows students to be more self-directed and takes advantage of their prior knowledge and skills in the use of new technologies." As eMINTS teachers, the authors (Michelle Nebel and Barbara Jamison) explore how new technologies can be integrated into the curriculum and classroom environments. To prepare students for participating fully in the world of the Internet, they designed learning experiences to address some of the concerns of "digital citizenship," which is defined as one's roles and responsibilities as a user of the Internet. In this article, the authors provide some examples of Internet sites and activities that a teacher can use to incorporate the skills, knowledge, and responsibilities of digital citizenship into an elementary classroom setting.
