This study examined the effects of a small group intervention targeting paraphrasing and text structure instruction on the main idea generation and reading comprehension of students with reading disabilities in Grades 4 and 5. Students (N = 62) were randomly assigned to receive the Tier 2-type intervention or business-as-usual instruction.…

We examine the efficacy of an intervention to improve word reading and reading comprehension in fourth- and fifth-grade students with significant reading problems. Using a randomized control trial design, we compare the fourth- and fifth-grade reading outcomes of students with severe reading difficulties who were provided a researcher-developed…

This randomized control trial examined the efficacy of an intervention aimed at improving multisyllabic word reading (MWR) skills among fourth- and fifth-grade struggling readers (n = 109, 48.6% male), as well as the relative effects of an embedded motivational beliefs training component. This study was a closely aligned replication of our earlier…

The purpose of this study was to assess whether intervention with an integrated focus on fraction and decimal magnitude provides added value in improving rational number performance over intervention focused exclusively on fractions. We randomly assigned 4th graders with poor whole-number performance to 3 conditions: a business-as-usual control…

The goal of this randomized controlled trial (RCT) was to evaluate the effectiveness of a small-group intervention in fractions for fifth-graders who are performing below grade level in mathematics. The impact of the fractions intervention was assessed on fifth-grade at-risk students' understanding of foundational fractions concepts and procedural…

The purposes of this study were to (a) investigate the efficacy of a core fraction intervention program on understanding and calculation skill and (b) isolate the effects of different forms of fraction word-problem (WP) intervention. At-risk fourth graders (n = 213) were randomly assigned to the school's business-as-usual program, or one of two…

The purposes of this study were to (a) investigate the efficacy of a core fraction intervention program on understanding and calculation skill and (b) isolate the effects of different forms of fraction word-problem (WP) intervention delivered as part of the larger program. At-risk 4th graders (n = 213) were randomly assigned at the individual…

Testing a component model of reading comprehension in a randomized controlled trial, we evaluated the efficacy of 4 interventions that were designed to target components of language and metacognition that predict children's reading comprehension: vocabulary, listening comprehension, comprehension of literate language, academic knowledge, and…

This study examined the effectiveness of a researcher-provided intervention with fourth graders with significant reading difficulties. The intervention emphasized multisyllable word reading, fluent reading of high-frequency words and phrases, vocabulary, and comprehension. To identify the participants, 1,695 fourth-grade students were screened…

Research examining effective reading interventions for students with reading difficulties in the upper elementary grades is limited relative to the information available for the early elementary grades. In the current study, we examined the effects of a multicomponent reading intervention for students with reading comprehension difficulties. We…

Research examining effective reading interventions for students with reading difficulties in the upper elementary grades is limited relative to the information available for the early elementary grades. In the current study, we examined the effects of a multicomponent reading intervention for students with reading comprehension difficulties. We…

This article describes the effects of an analysis-of-practice professional development (PD) program on elementary school students' (Grades 4-6) science outcomes. The study design was a cluster-randomized trial with an analysis sample of 77 schools, 144 teachers and 2,823 students. Forty-two schools were randomly assigned to treatment, (88.5 hours)…

This study investigated whether individual differences in working memory (WM) moderate effects of 2 variations of intervention designed to improve at-risk 4th graders' fraction knowledge. We also examined the effects of each intervention condition against a business-as-usual control group and assessed whether children's measurement interpretation…

The 2013 study, "Does Working Memory Moderate the Effects of Fraction Intervention? An Aptitude-Treatment Interaction," examined the impacts of the fluency and conceptual versions of "Fraction Face-Off!," a math instruction program designed to improve knowledge of fractions and decimals in fourth-graders at risk for low…

The present study used a randomized control trial to examine the effects of a widely used multicomponent Tier 2-type intervention, Passport to Literacy, on the reading ability of 221 fourth graders who initially scored at or below the 30th percentile in reading comprehension. Intervention was provided by research staff to groups of 4-7 students…
