In this study, we used a quasi-experimental, longitudinal design to examine the English language arts (ELA) and mathematics test scores of emergent bilinguals (EBs) in DLBE 50:50 models versus English as a second language (ESL) models in Indiana over four academic school years. With a focus on the midwestern U.S., we bring attention to a…

National studies reveal that 50 percent to 70 percent of community college students are required to take developmental, or remedial, math courses upon enrollment, and only 20 percent of developmental math students ever successfully complete a college-level math course.
