Child Study. Child study, also called paidology or experimental pedagogy, was the attempt to apply the methods of modern science to the investigation of children in order to discover the laws of normal child development.
The purpose of this study is to consider the effects on the family unit with the adoption of an older child. The survey instrument was distributed to selected residents in Snohomish County, Washington, and to selected students at The Masterâs College in Santa Clarita, California, during the spring of 2009.he reason for this would most likely be attributed to the effect of childrenâs previous experiences on their character (Ward, 1997, p. 257). These previous experiences often involve multiple foster homes and a discontinuity of social workers and parental figures (Schwartz, 2006, p. 38).
