In this article, the authors discuss how Bennington College Early Childhood Center (ECC) developed a dual language program. In a dual language program, children are immersed in two languages throughout the day. Each classroom has two teachers, one speaking English, the other the second language exclusively. Children learn the second language in much the same way they do their first language: hearing it used in the context of daily activity with concrete, observable referents. With increased language skills, the children demonstrated a growing awareness of how languages work. Here, the authors describe the process in refining the program, and its impact on children.
