This study used a multiple probe across participants design, replicated across two interventions and counterbalanced across participant groups to examine the effects of number sense intervention and extensive practice intervention on strategy transformation when students with mathematics learning disabilities (MLD) solved basic fact problems. In…

Using a low inference observation instrument, we investigated the effect of an ongoing, intensive, and structured virtual professional development [VPD] on fidelity of implementation across conditions in a randomized control trial validation study implemented in seven Texas school districts. The observations were collected three time in the…

A controlled quasi-experimental design was used to evaluate the effects of the use of MindPlay Virtual Reading Coach on participants' reading and spelling achievement. After attrition, participants included 170 students enrolled in eight second-grade classrooms (four classrooms in each school) in two public elementary schools in the southwestern…

This study examined teachers' implementation of an early literacy intervention, Systematic and Engaging Early Literacy (SEEL), on kindergarten children's development of early literacy skills. One hundred forty-nine kindergarten children (102 treatment) across six classrooms participated in this study. Results reveal that children who received SEEL…

A quasi-experimental study examined some effects of cross-age tutoring on fourth grade tutors' and second grade tutees' ability to spell accurately and correct errors on their own rough drafts. Half of the participating tutors were trained in tutoring skills; half were not. All participants were given pre- and post-assessments. On dictated writing…

The targeted reading intervention (TRI) is a professional development program for rural kindergarten and first grade classroom teachers to help them provide effective reading strategies with struggling readers. In two randomized controlled trials, the TRI was delivered two ways: (1) literacy coaches provided support for classroom teachers through…

The purpose of this research is to examine the impact of a Standards-based elementary mathematics curriculum on third grade students' mathematics performance. A total of 707 students participated in this study. Of this total, 368 students were from eight schools located within the same school district in a racially and ethnically diverse large…

This study examined the efficacy of a core kindergarten mathematics program, Early Learning in Mathematics (ELM), a 120-lesson program with four content strands: (a) number operations, (b) geometry, (c) measurement, and (d) vocabulary. The study utilized a randomized block design, with 129 classrooms randomly assigned within schools to treatment…

The purpose of this study was to conduct a preference trial as a preliminary test of preference effects on teacher behavior relative to implementation (adoption, adherence, quality). Teachers were randomly assigned to "preference" or "no-preference" groups and then trained to implement the intervention. Direct observation…

Reading Recovery (RR) is a short-term, one-to-one intervention designed to help the lowest achieving readers in first grade. This article presents first-year results from the multisite randomized controlled trial (RCT) and implementation study under the $55 million Investing in Innovation (i3) Scale-Up Project. For the 2011-2012 school year, the…

The purpose of this study was to examine whether the code-related features used in current methods of writing instruction in kindergarten classrooms transfer reading outcomes for kindergarten students. We randomly assigned kindergarten students to 3 instructional groups: a writing workshop group, an interactive writing group, and a control group.…

This randomized controlled experiment compared the efficacy of two response-to-intervention (RTI) models--typical RTI and dynamic RTI--and included 34 first-grade classrooms (n = 522 students) across 10 socioeconomically and culturally diverse schools. Typical RTI was designed to follow the two-stage RTI decision rules that wait to assess response…

Although kindergarten teachers often struggle with implementing technology, they are rarely involved in co-designing technology-rich learning activities. This study involved teachers in the co-design of technology-rich learning activities and sought to explore implementation and pupil learning outcomes. A case-study method was used to investigate:…

Achieve3000 publishes a number of online literacy programs that differentiate lessons and activities based on student performance. Magnolia Consulting--an independent, third party evaluation firm--assessed Achieve3000 Solutions' impact on student learning during the 2014-15 school year. The researchers used a randomized control trial, where…

"Un Buen Comienzo" [A Good Start] was a professional development program implemented with prekindergarten and kindergarten teachers in Chilean public schools serving low-income families. In a randomized trial, the program showed moderate to large impacts on classroom quality but no impacts on targeted child outcomes. To unpack these…
