The purposes of this study were (a) to identify measures that when added to a base 1(st)-grade screening battery help eliminate false positives and (b) to investigate gains in efficiency associated with a 2-stage gated screening procedure. We tested 355 children in the fall of 1(st) grade, and assessed for reading difficulty at the end of 2(nd) grade. The base screening model, included measures of phonemic awareness, rapid naming skill, oral vocabulary, and initial word identification fluency (WIF). Short-term WIF progress monitoring (intercept and slope), dynamic assessment, running records, and oral reading fluency were each considered as an additional screening measure in contrasting models. Results indicated that the addition of WIF progress monitoring and dynamic assessment, but not running records or oral reading fluency, significantly decreased false positives. The 2-stage gated screening process using phonemic decoding efficiency in the first stage significantly reduced the number of children requiring the full screening battery.
(a)确定添加到一年级基础筛查组合中有助于消除假阳性的措施;(b)调查与两阶段门控筛查程序相关的效率提升。我们在一年级秋季对355名儿童进行了测试,并在二年级末评估其阅读困难情况。基础筛查模型包括音素意识、快速命名技能、口语词汇和初始单词识别流畅性(WIF)的测量。在对比模型中,短期WIF进展监测(截距和斜率)、动态评估、阅读记录和口语阅读流畅性分别被视为额外的筛查措施。结果表明,添加WIF进展监测和动态评估可显著降低假阳性,而阅读记录或口语阅读流畅性则不然。在第一阶段使用音素解码效率的两阶段门控筛查过程显著减少了需要进行全面筛查组合的儿童数量。
