Today's young people do not need the technology education they are receiving to be successful in the 21st century, and there are growing indications that the high-tech lifestyle promoted by government and business may be harmful to them, a new report scheduled for release today concludes.

The report, titled "Tech Tonic" and issued by the nonprofit Alliance for Childhood, contends that there is scant evidence of long-term benefits from immersing preschool- and school-age children in electronic technologies.

"Increasing numbers of them spend hours each day sitting in front of screens instead of playing outdoors, reading, and getting much-needed physical exercise and face-to-face social interaction -- all of which, it turns out, also provide essential stimulation to the growing mind and intellect," according to the study.

The report makes a series of recommendations to parents, educators and policymakers, including declaring one day a week an electronic entertainment-free zone and shifting spending from unproven high-tech products in the classroom to children's unmet basic needs.

The alliance, a partnership of educators, researchers, health professionals and other advocates for children based in College Park, issued a report in 2000 that called for a moratorium on further introduction of computers in early-childhood and elementary education.
