We modeled word reading growth in typically developing (n = 118) and children with dyslexia (n = 20), Grades 2-5, across multiple exposures to 30 words. We explored the facilitative versus inhibitory effects of exposures to differential mixes of words that support high- versus low-frequency vowel pronunciations. One training corpus contained a…

Grounded in the simple view of reading, this study tracked the development of print-processing skill in high-, average-, and low-achieving readers at six time points across grades 1-3. Results showed large between-group differences in sight vocabulary, oral reading accuracy, and oral reading rate that remained stable from beginning of first grade…

Over the years, teachers have looked for the best way to teach their students to read. There are those who believe that teaching sight words is the best way to teach while others believe that a foundation in phonics instruction is a must. The purpose of this study is to determine the effect that phonics instruction has on the oral reading fluency…

PCI Education conducted a three-year longitudinal study to determine the comparative effectiveness of the "PCI Reading Program" ("PCI") for students with severe disabilities as implemented in Florida's Brevard Public Schools and Miami-Dade County Public Schools. The primary question addressed by the study is whether students…

The purpose of this study was to compare student's tested recognition of the Dolch 220 words with their responses to the 220 highest frequency words found by Kucera and Francis in their "Computational Analysis of Present-Day American English." Subjects consisted of 155 second graders and 179 third graders from classrooms in four schools…

PCI Education sought scientifically based evidence on the effectiveness of the "PCI Reading Program--Level One" for students with severe disabilities. During the 2007-2008 academic year. Empirical Education conducted a randomized control trial (RCT) in two Florida districts, Brevard and Miami-Dade County Public Schools. For this…

Examines the word-reading strategies of a sample of second- and third-grade students in normal classrooms, focusing on the students' relative reliance on decoding versus sight-word associations. Suggests that lack of efficient decoding skills will begin to take a toll on reading comprehension by grade 3. (SR)
