This study compared the use of two supplemental balanced and strategic reading interventions that targeted the decoding, fluency, and reading comprehension of upper-elementary and middle school students with reading disabilities (RD). All students had significant delays in decoding, fluency, comprehension, and language processing. Two comparable, intensive tutorial treatments differed only in the degree of explicitness of the comprehension strategy instruction. Overall, there was meaningful progress in students' reading decoding, fluency, and comprehension. Gains in formal measures of word attack and reading fluency after five weeks of intervention translated into grade-equivalent gains of approximately half a school year. Analysis of the trends in the daily informal fluency probes translated into a weekly gain of 1.28 correct words per minute. The more explicit comprehension strategy instruction was more effective than the less explicit treatment. Findings are discussed in light of the question of how to maximize the effects of reading interventions for older children with RD.
