Language immersion means a program in which the usual curriculum activities are conducted in a second language which is the medium of instruction rather than the object of instruction. There are variables in immersion programs as to the amount of time each day spent in the second language. In total immersion programs the second language is used for the entire school day during the first two or three years of the program. Students who go through the entire sequence of an elementary immersion program are able to communicate in the second language on topics appropriate to their age level. In addition to the goal of functional proficiency in the second language, immersion programs have as a further goal, the mastery of subject content material which is taught through the second language.
