本研究考察了是否需要一个最低水平的学前教育质量（阈值），以便在学前教育质量与儿童的学术、行为和工作记忆之间存在关系，在一个来自低财富农村社区的儿童样本中，儿童保育质量被发现低于更多的城市社区。参与者包括来自两个高度贫困的农村地区的849名儿童。采用CLASS观察量表对学前教育质量进行评定。儿童结果包括对早期语言、数学和工作记忆的直接评估，以及教师对注意力、情绪调节、问题行为和同伴关系的评分。分析包括测试先验指定切割点的分段回归分析和经验测试阈值的灵活b样条分析。结果显示了质量阈值的一些证据，表明质量与儿童的行为结果相关，高于而不低于切点。语言、读写和工作记忆没有显示阈值效应的证据。结果是在先前的混合证据的背景下讨论儿童保育质量阈值的其他样本主要是低收入学龄前儿童在中心为基础的儿童保育在更多的城市地区。(C) 2013爱思唯尔公司版权所有。
This study examined whether a minimum level of preschool quality (threshold) is needed in order for a relationship to exist between preschool quality and children's academic, behavioral, and working memory in a sample of children from low-wealth rural communities where quality child care has been found to be lower than more urban communities. Participants included 849 children from two high-poverty, rural regions. Preschool quality was rated using the CLASS observational measure. Child outcomes included direct assessments of early language, mathematics, and working memory, as well as teacher ratings of attention, emotion regulation, problem behaviors, and peer relationships. Analyses included piecewise regression analyses that tested a priori specified cut-points and flexible b-spline analyses that tested for thresholds empirically. Results indicated some evidence for quality thresholds, suggesting that quality was related to children's behavioral outcomes above, but not below, a cut-point. Language, literacy, and working memory did not show evidence of threshold effects. Results are discussed in the context of prior mixed evidence for child care quality thresholds in other samples of predominantly low-income preschoolers in center-based child care in more urban areas.
