Side note: At the link, there is an adorable photo of two little girls looking at a worm. Since the newspaper article is presenting the proposal in a positive light, it would like you to picture cute young girls benefiting by hands-on science classes. Please don't picture older boys slumped in chairs.
UPDATE: The same issue of the NYT has this article about a study showing about the time spent in day care:
A much-anticipated report from the largest and longest-running study of American child care has found that keeping a preschooler in a day care center for a year or more increased the likelihood that the child would become disruptive in class — and that the effect persisted through the sixth grade.
