Noting that the English-Only movement (which advocates that English be the official and only language used in the United States) dramatically influences the lives of language minority children, this Digest first examines the ideologies undergirding the English-Only movement. It then reviews the consequences of imposing this legislation on the language minority population. Next, the Digest presents a summary of research findings on the importance of mother tongue maintenance among language minority children. The Digest concludes by exploring the implications of the English-Only movement on equality and equity education for all children. (SR)
