Abecedarian Early Intervention Project
The Carolina Abecedarian Project was a controlled experiment that was conducted in 1972 in North Carolina, United States, by the Frank Porter Graham Child Development Institute to study the potential benefits of early childhood education for poor children to enhance school readiness. It has been found that in their earliest school years, poor children lag behind others, suggesting the fact that they were ill-prepared for schooling. 〔Alexander, K. L., & Entwisle, D. R. (1988). Achievement in the first 2 years of school: Patterns and processes. Monographs of the Society for Research in Child Development, 53 (Serial No. 218)〕 The Abecedarian project was inspired by the fact that few other early childhood programs could provide a sufficiently well-controlled environment to determine the effectiveness of early childhood training.
==Overview==
The participants in this experiment were 111 infants born between 1972 and 1977. Of these, 57 were given high-quality intervention, consisting in part of educational games based on the latest in educational theory. The other 54 acted as a control group. An overwhelming majority (98 percent) of the children who participated in the experiment were African-American. The average starting age of participants was 4.4 months.〔(Child Trends: Guide to Effective Programs for Children and Youth ), Child Trends 2003〕 Whereas other childhood programs started at age two, the Abecedarian Project started from infancy and continued for five years, a period longer than most other programs. The participants received child care for 6–8 hours a day, five days a week. Educational activities were game-based and emphasized language. The control group was provided with nutritional supplements, social services, and health care to ensure that these factors did not affect the outcomes of the experiment.〔(Ramey & Campbell, 1991 )〕 All the 111 infants were identified as "high risk" based on maternal education (which was on average 10th grade), family income, and other factors. The teacher-child ratio was low. It ranged from 1:3 for infants to 1:6 at age 5.〔IQ Testing 101, Alan S. Kaufman, 2009, Springer Publishing Company, ISBN 0-8261-0629-3 ISBN 9780826106292〕
