We present experimental evidence on the impact of a multi-faceted program that integrates technology-aided instruction, teacher training and coaching, community ownership, and free primary education. Our setting is three districts in rural Zambia, where we randomly assigned the program across 30 treatment and 33 control schools. The results show…

The effects of prior encodings of manipulatives (red and blue plastic chips) on children's ability to use them as representations of quantity were tested. First graders (N = 73) were assigned to four conditions in which the encoding of plastic chips was experimentally manipulated. All children then participated in an addition activity that relied…

The impact of supplemental handwriting and spelling instruction on learning to write was examined in an experimental study with first grade students who were not acquiring these skills as rapidly as their classmates. Thirty students (16 boys, 14 girls) were randomly assigned to a handwriting and spelling instructional condition or a phonological…

There has been a drastic increase in the use of technology in the classroom over the past 20 years. As computers and tablets permeate our schools, their presence is oftentimes seen as a cure to whatever problems may exist. While the promise of technology has held true within some domains, little has been done to examine its efficacy in some areas.…

Early number skills, comprised of both informal and formal skills, are associated with later mathematics achievement. Thus, the development of foundational early number skills is an important aspect of early mathematics instruction. This study explored relations between early number skills gains and mathematics achievement for students at risk for…

The purpose of this quantitative study was to examine the effects, if any, of a supplemental phonics curriculum, Saxon Phonics, on the reading achievement of first-grade students in one mountain-west, semirural, school district. The design was casual-comparative and ex post facto, and answered the questions: (1) Do students taught using a…

The purpose of this quantitative quasi-experimental group comparison study using a repeated measures comparison group design with random assignment of subjects to groups was to investigate the effects of handwriting instruction on reading progress for learners in grade 1 and grade 2. At three points in time, the number of words each student read…

It was investigated whether task-related body movements yield beneficial effects on children's learning of two-digit numbers and whether these learning effects are affected by mirror-based self-observation of those movements. Participants were 118 first-graders, who were randomly assigned to two movement conditions and two non-movement control…

The purpose of this pilot study is to analyze the efficacy of a program that combines fine motor activities, animated models, exercises on a digital tablet and paper-pencil exercises. The 10-week program with a 45-minute session and daily exercises was implemented in a class of 16 students of first grade (mean age = 6.9 years old), with another…

The purpose of this replication study was to examine the impact of the Teacher Study Group (TSG) professional development in vocabulary on first-grade teachers' knowledge of vocabulary instruction and observed teaching practice, and on students' vocabulary knowledge. Sixty-two schools from 16 districts in four states were randomly assigned to…

We report on a practitioner implementation of Fusion, a first-grade mathematics intervention. Studies such as this evaluation of a loose implementation under realistic conditions are important to curriculum developers' understanding of how evidence-based programs and tools work under a variety of implementation scenarios. In this…

This quasi-experimental study tested the efficacy of a research-based biliterate reading strategy, Lotta Lara, that is part of a larger paired literacy instructional program. Its purpose was to investigate whether Lotta Lara, which focuses on reading fluency, comprehension, and oracy through whole group instruction, impacted first grade emerging…

Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a…
