Oral language is crucial for social interaction and for learning in the classroom; it also provides the foundation for reading comprehension. It follows that children with language difficulties are at high risk of educational failure. Recently, a number of studies have demonstrated that it is possible to produce small but significant improvements in children’s oral language through targeted language interventions (d = 0.16) and, furthermore, that studies with high-quality implementation show larger effects (d = 0.24). There is also evidence that effects of language intervention can generalize to produce improvements in reading comprehension. Although further research examining the long-term effects of language interventions are needed, current findings have important implications for educational policy and practice.

可以提高儿童的语言技能：心理科学教育政策的教训

口语对于社交互动和课堂学习至关重要。它还为阅读理解提供了基础。由此可见，有语言障碍的儿童有很高的教育失败风险。最近，许多研究表明，通过有针对性的语言干预（d = 0.16），可以对儿童的口语产生微小但显着的改善（d = 0.16），此外，高质量实施的研究显示出更大的效果（d = 0.24）。 。也有证据表明，语言干预的效果可以普遍提高阅读理解能力。尽管需要进一步研究语言干预的长期影响，但目前的发现对教育政策和实践具有重要意义。
