In exploring the discussion about developmental psychology, there is a need to review the historical background of the works, which led to what we have today. Most of the work started as philosophical subjects with argument being the interplay between biology and culture. Leading these discussion on these dichotomous view were philosophers such as John Locke attributing development completely to the effect of sensory input. His view suggested that babies are born with a clean tablet where all information needed is input from experience. On the other side, of the discussion was the French philosopher Descartes' who believed that we are born with the specific kind of idea (Keller, 2000). Beside those two there were many other theory on human development one being development follow the same stages as the evolution of species. These theories had birth new ideas and propelled developmental Psychology to new heights and pushed researchers to develop different methods in conducting researches on children
One of the biggest steps made in developmental psychology came from Jean Piaget, whose developmental theory was based on his previous studies in biology. He believed that the structures of the body were adapted to fit the environment, so the structures of the mind developed to better fit with it the external world supporting his theory that children actively construct knowledge as they manipulate and explore their world (Berk, 2010). Piaget based his theory from his observation of children from their early age to adolescent. He observed them going through their everyday problems and from their response. Piaget view triggered many studies on children in some cases pushing the extent of what children can learn. In many cases, theorist and researchers, in the attempt to prove that children can learn more than what Piaget anticipated, they exposed children to more research.
Although Piaget theory encouraged the development of educational philosophies, his overwhelming contributions...
