Collaboration has become a key concept in the workplace, in research laboratories, and in educational settings. Companies want members of different departments located far apart to work together. Various government agencies try to establish collaborative relationships with private organizations. Academics and corporate researchers collaborate with far-flung colleagues to produce new knowledge. Students at all levels of our educational system are increasingly being asked to learn collaboratively. In addition, more work is being done online. Businesses communicate over the Internet, and increasing numbers of educational experiences are being delivered at a distance. Virtual high schools, traditional and for-profit distance education institutions, and colleges and universities are all among the current users of the Internet in education.
