This research responds to the call by early childhood educators advocating for more challenging mathematics curriculum at the primary level. The kindergarten Project M[superscript 2] units focus on challenging geometry and measurement concepts by positioning students as practicing mathematicians. The research reported herein highlights the…

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…

Objective: Statway is a community college pathways initiative developed by the Carnegie Foundation for the Advancement of Teaching designed to accelerate students' progress through their developmental math sequence to acquiring college math credit in statistics. Statway is a multifaceted change initiative designed to address the complex problems…

We examined the direct impact of an ongoing, intensive, and structured professional development (PD) within an English-as-second-language (ESL) instructional intervention on (a) teachers' time allocation in cognitive--academic language proficiency (CALP) and (b) Spanish-speaking English language learners' (ELLs) CALP development from the second to…

This study investigated the impact of a dynamic geometry (DG)-centered teacher professional development program on high school geometry teachers' content knowledge and their students' geometry learning. 64 geometry teachers were randomly assigned to an experimental (DG) group and a control group. Both groups received appropriate and relevant…

Previous research demonstrates that collective efficacy positively predicts students' academic achievement (e.g., Bandura, 1993; Goddard et al., 2000). However, unaddressed by the current literature is whether collective efficacy also works to reduce inequity by closing achievement gaps. To learn about the operation of collective efficacy, we…

This study examined the impact of independent practice of multiple-criteria text that targeted high-frequency words, decodability, and meaningfulness. Second-grade students, including at-risk students, were randomly assigned within classroom to a treatment group that read multiple-criteria text ("n" = 34), or contrast group that read…

Adolescents in the United States and their educators face an enormous challenge with respect to reading comprehension. College and career readiness standards outlined in the Common Core State Standards Initiative (2012) place increased emphasis on preparing students to read complex text across a range of content areas. At issue is how to develop…

The purpose of this varied replication study was to evaluate the effects of a supplemental reading intervention on the beginning reading performance of kindergarten students in a different geographical location and in a different instructional context from the initial randomized trial. A second purpose was to investigate whether students who…

The purpose of this study was to determine whether integrating encoding instruction with reading instruction provides stronger gains for students who struggle with reading than instruction that includes little or no encoding. An instructional design model was investigated to best fit the data of 175 first-grade readers at risk for reading…

Since 1994, the U.S. Department of Education (USDE) has provided funding to new charter schools through Charter School Program (CSP) grants designed to provide support for the planning and implementation of effective new charter programs. Grants are awarded to state education agencies, which then provide funding to approved charter schools through…
