This paper addresses some of the problems that society in general, and child care centers in particular, must confront due to the effects of the computer and mass media on the modern world. Children today live in a society increasingly dominated by computers and the mass media, and it is important that they be able to utilize these new technologies and information sources effectively. The New Information Technology at Children's Leisure Centers, or NIT project, and the Child Care in the Admass Society, or BITS project, have both worked with issues and problems relating to the effects of computers in society. The NIT project, conducted from 1985 to 1988, studied the effects of the introduction and use of computers on approximately 40 children and several instructors at 3 leisure centers, or after-school day care centers, in Sweden. Begun in 1988, the BITS project continued the study with about 75 children between 7 and 12 years of age at 4 leisure centers. Results of the study indicated that children were easier to motivate while working on the computer than at other times; writing was easier for the children on the computer than by hand; and instructors at the centers felt better supported in their role as educators and better planned their work after the computers were introduced in the centers than before.
