FLEX programs introduce students to other cultures and to language as a general concept. Time is spent exploring one or more languages or presenting information about language itself. The emphasis is not on attaining proficiency. These programs, however, can provide a basis for later learning. In most cases, learning another language enhances a child's English ability.
Children can learn much about English by learning the structure of other languages.
Common vocabulary also helps children learn the meaning of new words in English. Experimental studies have shown that no long-term delay in native English language development occurs in children participating in second language classes, even in full immersion programs. In fact, children enrolled in foreign language programs score statistically higher on standardized tests conducted in English. A number of reports have demonstrated that children who have learned a second language earn higher SAT scores, particularly on the verbal section of the test. One study showed that by the fifth year of an immersion program, students outperformed all comparison groups and remained high academic achievers throughout their schooling.
