Wagner, Richard K.; Zirps, Fotena A.; Edwards, Ashley A.; Wood, Sarah G.; Joyner, Rachel E.; Becker, Betsy J.; Liu, Guangyun; Beal, Bethany – Journal of Learning Disabilities, 2020
How prevalent is dyslexia? A definitive answer to this question has been elusive because of the continuous distribution of reading performance and predictors of dyslexia and because of the heterogeneous nature of samples of poor readers. Samples of poor readers are a mixture of individuals whose reading is consistent with or expected based on…

Fuchs, Lynn S.; Gilbert, Jennifer K.; Powell, Sarah R.; Cirino, Paul T.; Fuchs, Douglas; Hamlett, Carol L.; Seethaler, Pamela M.; Tolar, Tammy D. – Developmental Psychology, 2016
The purpose of this study was to examine child-level pathways in development of prealgebraic knowledge versus word-problem solving, while evaluating the contribution of calculation accuracy and fluency as mediators of foundational skills/processes. Children (n = 962; mean 7.60 years) were assessed on general cognitive processes and early…

James E. Connell Jr. – ProQuest LLC, 2005
Curriculum-based measurement (CBM) is a well established tool for formative assessment. CBM has also been used for prediction of state test scores. However, validity coefficients between math-CBM and state tests have been moderate at best (Skiba, Magnusson, Martson, and Erickson, 1986; Martson, 1989; Putnam, 1989). The purpose of the present…

Montani, Teresa Oettinger; Smith, Lisa – Learning Disabilities: A Multidisciplinary Journal, 2004
This study examined the performance of one hundred thirty-one fifth graders on timed versus untimed mathematics tests. Measures of math fluency and calculation were administered. Low achieving students performed poorly on both calculation and math fluency. Normally achieving children performed within the average range on both calculation and math…
