I could tell you to write your state and national representatives, but I have done that myself with disappointing results—not even receiving a lousy form letter in response. The fact of the matter is most of our politicians know little or nothing about early childhood education, and it's certainly not a priority for them. Their ignorance on the subject is one of the reasons why we're in this mess in the first place. In their minds, academic rigor sounds good in 12 grade, 8th grade, 4th grade, and preschool with no distinction. They are clueless about the devastating effects a lack of play, creativity, and socialization in the early years has on young people and society.
With that pessimistic message out of the way, I'm happy to say that the most effective way to help preschoolers is getting involved with the fantastic organization called “Defending the Early Years.” On their excellent website https://www.deyproject.org/, you can join their e-mail list, sign up for updates, and make a tax-deductible donation. There are wonderful articles written by leaders in the movement such as Dr. Nancy Carlsson-Page and Dr. Diane Levin, who advocate for play-based preschools and developmentally appropriate practices. There's information on how you can get involved.
“Defending the Early Years” informs you of the issues and research in early childhood education so you'll feel confident about communicating them to others and becoming an advocate yourself. There are so many misconceptions that parents and the public at large hold that need to be set straight. Many misguided folks believe that kids today are smarter than ever before because of early academic rigor and technology. They don't realize that the decrease in play during the early years corresponds to the rise in serious health issues among children and teens: depression, anxiety, obesity, suicide, and narcissism. They don't realize the decline in creative and critical thinking.
