Improving English reading fluency and comprehension for children with reading fluency disabilities
Metsala, J. L., & David, M. D. (2022)
This study explored SpellRead's effects on two groups of students: those with fluency-defined disabilities and those with decoding-defined disabilities. Students with fluency-defined disabilities saw growth in fluency scores. Reading comprehension scores moved to the average range for both groups of students.
The Effects of a Computer-based Early Reading Program on the Literacy Skills of Kindergarten Students
Metsala, J. L., & Kalindi, S.C. (2022)
The creator of SpellRead developed a computer game called Ooka Island, based on the same principles as SpellRead. This study found that reading skills scores were boosted for kindergarten students who played Ooka Island in addition to their usual class instruction.
The Effects of Age and Sublexical Automaticity on Reading Outcomes for Students with Reading Disabilities
Metsala, J. L., & David, M. D. (2017)
For students with reading disabilities, becoming automatic with sublexical patterns contributed to better reading fluency. Students in all age groups made meaningful gains in reading fluency.
An Examination of Reading Skills and Reading Outcomes for Youth Involved in Crime Prevention Program
Metsala, J. L., David, M. D., & Brown, S. (2017)
This study explored the effects of a SpellRead intervention for youth in a crime prevention program. Word reading and reading fluency scores improved for this cohort of students. Reading comprehension skills made gains for this group of students.

Identifying Phonological Awareness Deficits with Event-Related Brain Potentials
Newman, R. L., Connolly, J. F., McIvor, K., MacDonald, W., & Arnold, S. (2001)
In this comprehensive study, we delve into the intricate relationship between phonological awareness and brain function, utilizing advanced Event-Related Brain Potentials (ERPs) to uncover insights into potential deficits. By examining the neural responses associated with phonological processing tasks, we aim to shed light on how ERPs can serve as valuable tools in identifying and addressing phonological awareness challenges.
