Conceptual replications are part and parcel of education science. Methodologically rigorous conceptual replication studies permit researchers to test and strengthen the generalizability of a study's initial findings. The current conceptual replication sought to replicate the efficacy of a small-group, first-grade mathematics intervention with 240…

Instructional interactions that occur between teachers and students around foundational mathematics topics are critical for supporting mathematical proficiency among students with mathematics learning disabilities (MLD). This study investigated whether the initial mathematics skill of 880 kindergarten students at risk of MLD predicted the quantity…

Group size and treatment intensity are understudied topics in mathematics intervention research. This study examined whether the treatment intensity and overall intervention effects of an empirically validated Tier 2 mathematics intervention varied between intervention groups with 2:1 and 5:1 student-teacher ratios. Student practice opportunities…

Implementation of evidence-based practices (EBPs) is paramount to students' development of mathematics proficiency. This study investigated "practice-based evidence" of interventionists' actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data collected in a…

Research shows low-income students suffer disproportionate learning loss over the summer and because those losses accumulate over time, they contribute substantially to the achievement gap between low- and higher-income children. The Wallace Foundation is funding a five-year demonstration project to examine whether summer learning programs can…

This is the final evaluation report for Boston's Title I Early Childhood Jackson-Mann Developmental Program (1980-81). The Early Childhood component serves about 1000 4-year-olds (kindergarten I) and 5-year-olds (kindergarten II) in an effort to raise the level of educational achievement among children identified as needing special assistance. The…
