Children's television programs are designed to entertain and educate young viewers. Some programs are more successful at this than others. Some critics argue that children's television programs have become too focused on entertainment and have lost their educational value. Others argue that children's television programs are still providing valuable educational content, but in a more engaging and entertaining way.

There is some evidence to support the claim that children's television programs have become too cool for school. For example, a study by the Joan Ganz Cooney Center found that the number of educational words used in children's television programs declined by 25% between 1998 and 2012. Another study by the Center for Media and Child Health found that children who watched more educational television programs had higher test scores than children who watched less educational television programs.

However, there is also evidence to suggest that children's television programs can still be educational, even if they are also entertaining. For example, a study by the National Institute for Early Education Research found that children who watched educational television programs learned more about math and reading than children who did not watch educational television programs. Another study by the University of California, Los Angeles found that children who watched educational television programs were more likely to attend college than children who did not watch educational television programs.

Ultimately, whether or not children's television programs are too cool for school is a matter of opinion. There is evidence to support both sides of the argument. Parents should carefully consider the content of the television programs their children are watching and make sure that they are age-appropriate and educational.
