The authors report the findings of a survey study in which they investigated high school social studies teachers' current practices, challenges, and needs in relation to instruction of English language learners (ELLs). Thirty-three high school social studies teachers in six English as a second language (ESL)-centered schools in central Virginia participated in the study. Drawing on the findings, three themes demand particular attention: the challenges that social studies teachers face teaching ELLs; the accommodations teachers currently make for ELLs; and the types of support teachers need to teach ELLs social studies more effectively. The authors include findings from the field of second-language education to raise social studies teachers' consciousness about their ELLs' needs and conclude with a number of practical suggestions related to instruction and differentiation that are crucial for social studies teachers to help ELLs learn effectively. Further dialogues are needed, particularly regarding ESL inclusion and teachers' critical awareness of serving this particular group of students. (Contains 3 tables and 1 note.)
