The purposes of this study were twofold. The first was to test the efficacy of two versions of the "Super Solvers" (SS) intervention for fourth- and fifth-grade students at-risk for mathematics learning disabilities (MLD). The second was to test the value of adding an error analysis component to the SS intervention. Students were…

This longitudinal study examined story-writing development of students from Grade 4 to Grade 6, comparing the developmental trajectories of English as a first language (EL1s; n = 43) and English learners (ELs; n = 108) in general, and in groups of EL1s and ELs with typically developing and poor reader profiles. In relation to their EL1 or EL…

The purpose of this analysis was to examine achievement gaps on fractions for very-low-performing students as a function of whether they receive inclusive fraction instruction or specialized fraction intervention and with the shift to Common Core State Standards (CCSS). In three randomized control trials conducted in 3 consecutive years, 203…

The purpose of this set of analyses, conducted on a randomized control trial examining the effects of a fourth-grade fraction intervention, was to assess the initial academic deficit severity hypothesis. With this hypothesis, at-risk students with more severe initial academic deficits are expected to profit less from intervention than do students…

The study examined the effects of "Fraction Challenge," a supplemental small-group tutoring math program that focuses on improving student understanding of fractions. Study authors randomly assigned fourth grade "at-risk" students in 53 classrooms in 13 schools to either an intervention group that received "Fraction…

"Fast ForWord"[R] is a computer-based reading program intended to help students develop and strengthen the cognitive skills necessary for successful reading and learning. The program, which is designed to be used 30 to 100 minutes a day, five days a week, for 4 to 16 weeks, includes two components. The first component aims to build…
