Who said you plunk the children in school nine days out of ten?

The quote "You plunk the children in school nine days out of ten" is often attributed to John Holt, an American educator and author. He is known for his critique of traditional schooling and advocacy for child-centered learning.

While Holt didn't write the exact phrase, it reflects the sentiment he expressed in his book "How Children Learn," where he criticizes the "factory model" of education that treats children as passive recipients of knowledge. He argued that this system is ineffective and harmful, and that children learn best through active exploration and discovery.

However, it's important to note that the exact origin of the quote is unclear, and it's possible that other educators have expressed similar sentiments.
