Thank you for the link. It was a very informative article. They comparted the child-parent schools to Head Start, which is more developmental than academic, to my knowledge. What I am wondering is how much of the benefit results from the actual preschool curriculum, and how much is the result of the parent education and involvement? Most universal pre-k's do not have that component. As a person who teaches parent particiaption preschool, I would argue that getting the parents involved and providing parent education on child development and how to help their children learn may be as beneficial, if not more so, than the academic preschool curriculum. What do you think?
