摘要

本研究考察了来自美国大西洋中部地区的学习活动对一年级和二年级儿童早期分数知识的影响（N = 83）：样本中42%为男性，45%为女性，13%未报告。种族/族裔分类为白人22.9%，黑人27.7%，亚洲人4.8%，西班牙人10.8%，多种族14.5%，19.3%未报告。儿童被随机分配到实验分数训练组或积极对照组。混合方差分析对分数知识表现出显著的时间×条件交互作用。虽然两组从测试前到测试后都表现出显著的改善，但训练组的儿童在分数知识方面表现出很大的影响（d = 1.08），而对照组的影响要小得多（d = 0.27）。

Informal learning activities improve early fraction knowledge: A randomized controlled study.

This study examined the effects of learning activities on first- and second-grade children's early fraction knowledge (N = 83) from the mid-Atlantic region of the United States: 42% of the sample was male, 45% female, and 13% unreported. The racial/ethnic breakdown was 22.9% White, 27.7% Black, 4.8% Asian, 10.8% Hispanic and 14.5% multiracial, with 19.3% unreported. Children were randomly assigned to an experimental fraction training group or an active control group. A mixed ANCOVA showed a significant Time × Condition interaction on fraction knowledge. Although both groups demonstrated significant improvement from pretest to posttest, children in the training group exhibited a large effect (d = 1.08) on fraction knowledge compared to a much smaller effect for the control group (d = 0.27).
