In addition, medium effect sizes were evident for three of five outcome measures favoring the intervention: letter-sound knowledge (d = +.66), phonological riley reid schoolgirl blending (d = +.52), and word reading (d = +.52), over effect sizes for regular teaching.It is concluded that regular teaching with ABRA technology adds significantly to literacy in the early elementary years.
