题型:填空题

Tre’S mom,Christina Thompson, cannot believe how much her son already learned this year in his full-day, free pre-school class in Oklahoma City. “Since he’s been in school his vocabulary has increased surprisingly,” Thompson says. “The other day he came home and said, ‘You know what ,mom? You are being ridiculous,” Thompson laughs quietly. “And then he asked, ‘Do you know what ‘ridiculous’ means, mom?’” Tre knows the entire alphabet, his numbers to 100,and he’s starting to read. And letters and numbers aside, Thompson is most struck by how fast Tre is absorbing vocabulary and language.

Of course, not all pre-school is created equal. High quality pre-schools have well-trained, well-educated teachers in the classroom (much like Tre Thompson’s teacher Mrs. Wallace, who uses play-based learning to teach both academics and social skills and can rattle off (飞快说出) a battery of data on how well her students are progressing towards their year-end goals). Texas can also offer a model for educator development: its Texas School Ready! Campaign has proven to increase the quality of participating pre-schools by providing early childhood teachers with coaching, professional development, research-based curriculum (课程),and progress monitoring. States and districts should also combine pre-school with the K-12 system, as Oklahoma does ,so that children enter kindergarten smoothly.

Oklahoma is one of the leading states in providing students like Tre with free ,full-day pre-school. And the results are already paying off: According to a 2012 study, Oklahoma kids that went through pre-school showed vocabulary gains 28% higher than those of children without pre-school, and math gains 44% higher than non-pre-school kids. And we know that high-quality pre-school doesn’t just mean higher scores in elementary school. They were more likely to have graduated from high school and less likely to have committed a violent crime. They also earned more money and were more likely to be employed.

We know pre-school works, so let’s stop talking and start building a system where all children have access to excellent early childhood education. As any well-educated four year old could tell us, not doing so would be ridiculous.
