We estimate the societal costs associated with corequisite and traditional pre-requisite English developmental education and compare them to societal benefits. Our context is the randomized controlled trial conducted by Miller et al. (2022) that estimated the effects of three different approaches to English corequisites implemented in 5 Texas…

This randomized controlled trial in 55 low-performing schools across Florida compared 2 early literacy interventions--1 using stand-alone materials and 1 using materials embedded in the existing core reading/language arts program. A total of 3,447 students who were below the 30th percentile in vocabulary and reading-related skills participated in…

This study explores preliminary results from a pedagogical intervention designed to improve instruction for all students, particularly emergent bilinguals in the United States (or English language learners). The study is part of a larger efficacy randomized controlled trial (RCT) of the Instructional Conversation (IC) pedagogy for improving the…

Every Classroom, Every Day (ECED) is a set of instructional improvement interventions designed to increase student achievement in math and English/language arts (ELA).

By 2013, all 50 states and the District of Columbia had adopted college- and career-ready standards in English language arts and mathematics, placing a greater emphasis on argument writing to prepare students for life after high school. Solving the specific problem of how to help teachers teach to new standards for argument writing as well as the…

This study investigates the impact of a professional development program that included two distinct components: strategies for infusing student-talk into grade-level lessons in science and mathematics; and school-level learning communities focused on readings and discussions of student-talk research. This article reports the program's impact on…

This study examines the interaction between the fidelity of implementation of a set of research-based strategies--Collaborative Strategic Reading (CSR)--and outcomes for students with mild to moderate disabilities using data from two nonoverlapping studies in middle school language arts and reading classrooms (Study 1) and middle school social…

The Instructional Conversation (IC) is a complete classroom pedagogy that focuses on teaching through small-group dialogue with students allowing responsive instruction for each student. The IC is anchored by cognitive-developmental theory and by four decades of multi-method quasi-experimental studies. This study describes the first research of an…
