In the 2015-16 school year, there were 4.8 million English learners (ELs) students in grades K-12 in U.S. public schools, accounting for 10 percent of all enrolled students (U.S. Department of Education 2018). Over school years 2009-10 to 2014-15, 32 states saw increases in their EL student enrollments, and for five of those states, the increases were over 40 percent (U.S. Department of Education 2017a). Also, over the past decades, teachers have gained increased access to digital technologies for instruction (U.S. Department of Education 2017b). For example, as of 2009, almost every public school (98 percent) had internet access and almost all teachers (97 percent) had one or more computers in their classrooms (Gray, Thomas, and Lewis 2010a, 2010b). Many teachers report using Digital Learning Resources (DLRs) to enhance and differentiate their students' language and content area instruction. This report describes data collected in school year 2016-17 to learn about the use of DLRs in instructing EL students through a nationally representative survey of districts that enrolled EL students and a teacher survey that included mainstream teachers of EL students and EL specialists. The teacher sample was not nationally representative and those results should be interpreted with caution. The study included six case studies to provide illustrative vignettes and practitioner comments. [For the technical appendices, see ED600462.]
