本研究的目的是确定工作记忆（WM）的哪些成分在预测有严重数学困难（MD）的英语学习者（N= 157）的数学发展中起重要作用。方法用英语和西班牙语进行一系列测试，评估计算、阅读、词汇、抑制、结果工作记忆执行成分的增长与数学成绩的增长有关。精通双语儿童（精通西班牙语和英语词汇）的MD儿童在3年级时的数学计算、流体智力、阅读和西班牙语工作记忆的测量上优于不太精通双语的MD儿童。结论工作记忆执行成分的增长与数学计算的增长显著相关，在测试波中提高双语熟练程度在MD儿童的数学和认知表现中产生了积极的收益。
PurposeThe purpose of this study was to determine those components of working memory (WM) that play a significant role in predicting math growth in children who are English language learners (N= 157) with serious math difficulties (MD).MethodA battery of tests was administered in English and Spanish that assessed computation, reading, vocabulary, inhibition, and components of WM in Grade 1 children with follow-up testing in Grades 2 and 3.ResultsThe results indicated that growth in the executive component of WM was related to growth in math performance. Proficient bilingual children (proficient in both Spanish and English vocabulary) with MD outperformed less proficient bilingual children with MD on measures of math calculation, fluid intelligence, reading, and Spanish WM at Grade 3.ConclusionGrowth in the executive component of WM is significantly related to growth in math computation, and increased bilingual proficiency across testing waves yielded positive gains in both math and cognitive performance in children with MD.
