摘要
家庭扫盲活动影响儿童的突发扫盲进步和阅读指导的准备。为了帮助家长利用这一机会,我们开发了一种新的新兴识字筛选器(ELS),并对独立的幼儿园前样本进行了两项心理测量特性研究。研究1 (n = 812,年龄54.4个月,男性49.4%,白人46.1%)探索性因素分析(EFA)支持5因素结构。EFA和项目校准支持从原来的30个测试项目中删除10个项目。由此产生的20个项目的ELS与标准化的应急识字测量,Get Ready to Read - Revised具有良好的信度(Cronbach's alpha = .83)和显著的正相关(r = .50, p < .001)。对于研究2 (n = 959,年龄为53.5个月,男性占52.3%,白人占60.3%),验证性因素分析(CFA)支持双因素模型,该模型捕获了5个特定子因素和一个总体紧急读写能力因素的直接影响。使用15分的切口评分,ELS表现出中等的敏感性(0.71)和特异性(0.61)。阴性预测值高,阳性预测值低。总体而言,ELS表现出可接受的心理测量特征,供学龄前儿童的父母使用,为普遍的紧急读写能力筛查提供了一个有前途的新工具,并提供了一个确定儿童在紧急读写能力发展阶段的机会。讨论了进一步研究和实践的意义。(PsycINFO数据库记录
Psychometric profile of an experimental Emergent Literacy Screener for preschoolers.
Home literacy activities influence children's emergent literacy progress and readiness for reading instruction. To help parents fulfill this opportunity, we developed a new Emergent Literacy Screener (ELS) and conducted 2 studies of its psychometric properties with independent prekindergarten samples. For Study 1 (n = 812, Mage = 54.4 months, 49.4% male, 46.1% white) exploratory factor analyses (EFA) supported a 5-factor structure. EFA and item calibration supported the removal of 10 items from the original 30 test items. The resultant 20-item ELS demonstrated good reliability (Cronbach's alpha = .83) and significant positive correlation, r = .50, p < .001 with a standardized emergent literacy measure, Get Ready to Read - Revised. For Study 2 (n = 959, Mage = 53.5 months, 52.3% male, 60.3% white), confirmatory factor analyses (CFA) supported a bifactor model, which captured direct effects of 5 specific subfactors and an overarching emergent literacy factor. Using a cut score of 15, the ELS demonstrated moderate sensitivity (.71) and specificity (.61). Negative predictive value was high, whereas positive predictive value was low. Overall the ELS demonstrated acceptable psychometric characteristics for use by parents of prekindergarten children, providing a promising new tool for universal emergent literacy screening and an opportunity to identify where children are in their emergent literacy development. Implications for further research and practice are discussed. (PsycINFO Database Record
