It is widely believed that increasing parental involvement can improve children's educational outcomes although we lack good evidence for such claims. This study evaluated the effectiveness of a parent-delivered early language enrichment programme.
We conducted a randomised controlled trial (RCT) with 208 preschool children and their parents living in socially diverse areas in the United Kingdom. Families were allocated to an oral language programme (N = 103) or an active control programme targeting motor skills (N = 105). Parents delivered the programmes to their child at home in daily 20-min sessions over 30 weeks of teaching.
Children receiving the language programme made significantly larger gains in language (d = .21) and narrative skills (d = .36) than children receiving the motor skills programme at immediate posttest. Effects on language were maintained 6 months later (d = .34), and at this point, the language group also scored higher on tests of early literacy (d values=.35 and .42). There was no evidence that the movement programme improved motor skills.
This study provides evidence for the effectiveness of a parent-delivered language enrichment programme. Further large-scale evaluations of the programme are needed to confirm and extend these findings.
人们普遍认为，增加家长的参与度可以提高孩子的教育成果，尽管我们缺乏此类说法的有力证据。本研究评估了一种由家长提供的早期语言强化计划的有效性。
我们在英国社会多样化地区进行了一项随机对照试验（RCT），共有 208 名学龄前儿童及其家长参与。家庭被分配到口语语言计划（N=103）或针对运动技能的积极对照计划（N=105）。家长在 30 周的教学中，每天在家中以 20 分钟的时间为孩子提供这些计划。
与接受运动技能计划的儿童相比，接受语言计划的儿童在语言（d=0.21）和叙事技能（d=0.36）方面的即时后测得分显著更高。语言方面的效果在 6 个月后仍保持不变（d=0.34），此时，语言组在早期读写测试中的得分也更高（d 值为 0.35 和 0.42）。没有证据表明运动计划能提高运动技能。
本研究为家长提供的语言强化计划的有效性提供了证据。需要进一步进行大规模评估该计划，以确认和扩展这些发现。
