Abstract
This research adopts a collective case study to explore the quantity (time allocations for key literacy components and group configurations) and the quality of English language arts (ELA) instruction for Grade 1 English language learners (ELLs) across six classrooms in three Indiana elementary school districts during the 2019–2020 school year. Three teachers (treatment group) were participants in a year-long professional development (PD) program consisting of ELL teacher licensure coursework (plus instructional coaching for two of the treatment teachers). The other three teachers (control group) did not participate in the PD program.
