The purpose of this article is to describe the relationship of initial skill and rate of progress on a measure of the alphabetic principle, Nonsense Word Fluency (NWF), to first-grade reading outcomes as measured by Oral Reading Fluency (ORF). In addition, we describe a scoring approach to NWF where the predominant decoding strategy (i.e.,…

The purpose of this varied replication study was to evaluate the effects of a supplemental reading intervention on the beginning reading performance of kindergarten students in a different geographical location and in a different instructional context from the initial randomized trial. A second purpose was to investigate whether students who…

This study compared the effects of 2 supplemental interventions on the beginning reading performance of kindergarteners identified as at risk of reading difficulty. Students (N = 206) were assigned randomly at the classroom level either to an explicit/systematic commercial program or to a school-designed practice intervention taught 30 min per day…
