Research on students in kindergarten to grade 12 is analyzed to provide this review of scientific research on the learning outcomes of students with limited or no proficiency in English in U.S. schools. The primary chapters of the book focus on these students' acquisition of oral language skills in English, their development of literacy (reading & writing) skills in English, instructional issues in teaching literacy, and achievement in academic domains (i.e., mathematics, science, and reading). The book provides a unique set of summary tables that supply details about each study.
