Preschool-age children identified as at risk for later reading difficulties can benefit from supplemental, small-group emergent literacy intervention. As such interventions become commercially available and marketed to preschool programs, it is important to understand their impacts when implemented by intended end users under routine conditions.…

An ever-growing call for the use of evidence-based practice has come up against the logistical hurdles of a lack of resources and expertise, particularly in rural schools that work with historically underserved students. Although integrated learning systems (ILSs)--stable and likely requiring fewer resources than personnel--do not offer a complete…

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.…

Preschoolers can learn vocabulary through shared book reading, especially when given the opportunity to predict and/or reflect on the novel words encountered in the story. Readers often pause and encourage children to guess or repeat novel words during shared reading, and prior research has suggested a positive correlation between how much readers…

We report the results of a preregistered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no 2 consecutive problems require the same…

This study investigated the influence of teaching letter names and sounds in isolation or in the context of storybook reading on preschool children's early literacy learning and engagement during instruction. Alphabet instruction incorporated paired associate learning of correspondences between letter names and sounds. In Decontextualized…

This study assesses the implementation and impacts of the Teacher Potential Project (TPP), a program designed by EL Education and which includes an English language arts (ELA) standards-aligned curriculum and embedded professional development for teachers. The study uses a randomized controlled trial (RCT) design to assess the impacts of TPP on…

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…

Analyses of literacy and numeracy levels worldwide by the Organisation for Economic Cooperation and Development suggest that the U.S. population has one of the lowest numeracy levels among developed nations. Sixty-four percent of American adults are unable to use math and interpret math problems that most higher-level jobs require, and a full 30…

Community colleges are a large sector of postsecondary education. In 2016-2017, the United States had nearly 1,000 public 2-year postsecondary institutions (community colleges), serving almost nine million students, representing 39% of all undergraduates. The majority of entering community college students require developmental (or remedial) math.…

We present findings from a randomized controlled trial of "Descubriendo la Lectura" (DLL), an intervention designed to improve the literacy skills of Spanish-speaking first graders, who are struggling with reading. DLL offers one-on-one native language literacy instruction for 12 to 20 weeks to each school's lowest performing…

Considerable research has examined interventions that facilitate school readiness skills in young children. One intervention, "Red Light, Purple Light Circle Time Games" (RLPL; Tominey and McClelland, 2011; Schmitt et al., 2015), includes music and movement games that aim to foster self-regulation skills. The present study (N = 157)…

Empirical Education Inc. is the independent evaluator of SRI International's 2014 Investing in Innovation (i3) Development grant called Redesigning Secondary Courses to Improve Academic Outcomes for Adolescents with Disabilities and Other Underperforming Adolescents. The goal of the grant is to develop "Enhanced Units" that combine…

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…
