Students and educators see subjects come to life as they study topics such as tropical timber resources, environmental crises, or the AIDS pandemic. Science classes can also communicate directly with other science classes around the world to conduct research or explore and share ideas. In one recent effort, for example, elementary school students from across the United States measured daily precipitation and the acidity of collected samples of rainwater. This information was shared on a computer network with classes from many parts of the country, and a daily acid rain map was created. A common complaint of science teachers is the feeling of isolation from other professionals with similar interests.
Teachers can share ideas and activities through the use of electronic bulletin boards.
Networks can also serve as resource retrieval databases. Data retrieved from computer networks can be analyzed by students. Computer networking improves communication and data exchange by allowing participation in ongoing computer conferences as well as private e-mail. Increased productivity, creativity, and professional activity are some of the results of using computer networks. Using a computer network can save communication time and money.
