The Early Childhood Longitudinal Study (ECLS) program provides data about the development of children in the United States. [1] It is carried out by the Institute of Education Sciences . It provides data on children's status at birth and at various points thereafter.
It has been found that in their earliest school years, poor children lag behind others, suggesting they were ill-prepared for schooling. [1] 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.
A longitudinal study (or longitudinal survey, or panel study) is a research design that involves repeated observations of the same variables (e.g., people) over long periods of time (i.e., uses longitudinal data). It is often a type of observational study, although it can also be structured as longitudinal randomized experiment. [1]
The Dunedin Multidisciplinary Health and Development Study (also known as the Dunedin Study) is a detailed study of human health, development and behaviour.Based at the University of Otago in New Zealand, the Dunedin Study has followed the lives of 1037 babies born between 1 April 1972 and 31 March 1973 at Dunedin's former Queen Mary Maternity Centre since their birth.
A 2005 longitudinal study of 123 3 and 4-year-old black children conducted a cost-benefit analysis, reports that for every $1 invested in preschool education, there is a return on the investment of $12.90. [4]
By the time children were 10, there wasn't much of a difference in how children in the two groups performed on tests of cognitive ability. Because the study was conducted in the 1960s, researchers have been able to follow the children who went through the Perry Preschool Program through adulthood. Economist and Nobel laureate James Heckman has found that adults from the treatment group were ...
The early years of a child's life are most critical to their development. [165] In understanding child behavior there are many different types ways to analyze it. [165] There is a multiple stage behavior model that it can be broken down into. [165]
The Twins Early Development Study (TEDS) is an ongoing longitudinal twin study based at King's College London.The main goal of TEDS is to use behavioural genetic methods to find out how nature and nurture (environments) can explain why people differ with respect to their cognitive abilities, learning abilities and behaviours.
