Abstract
In this study, 12 students receiving special education services were systematically monitored from two reading curricula concurrently throughout the academic year. Long range goal sampling was used to select measurement passages from two sources: their instructional reading program, which contained highly controlled vocabulary and the curriculum of the mainstream, representing a traditional basal. Paired t-tests were computed to ascertain whether the curriculum made an impact on several indices of performance, some of which were static (measured once, like first performance level in baseline) and others which were dynamic (measured over time, like the average slope of improvement throughout a phase). Although some differences in performance were significant in both static and dynamic indices, performance changes over time were quite comparable in both curricula.
