Despite calls to expand early childhood education (ECE) in the United States, questions remain regarding its medium- and long-term impacts on educational outcomes. We use meta-analysis of 22 high-quality experimental and quasi-experimental studies conducted between 1960 and 2016 to find that on average, participation in ECE leads to statistically significant reductions in special education placement ( = 0.33 , 8.1 percentage points) and grade retention ( = 0.26 , 8.3 percentage points) and increases in high school graduation rates ( = 0.24 , 11.4 percentage points). These results support ECE's utility for reducing education-related expenditures and promoting child well-being.
尽管美国国内呼吁扩大幼儿教育(ECE),但其对教育成果的中长期影响仍存在疑问。我们对1960年至2016年间开展的22项高质量实验性和准实验性研究进行了荟萃分析,发现平均而言,参与幼儿教育能在统计上显著降低接受特殊教育的比例(效应量=0.33,降低8.1个百分点)和留级率(效应量=0.26,降低8.3个百分点),并提高高中毕业率(效应量=0.24,提高11.4个百分点)。这些结果支持了幼儿教育在减少教育相关支出和促进儿童福祉方面的作用。
