Although monolingual speakers often do not realize it, the majority of children around the world are bilingual, meaning that they understand and use two languages (Meyers-Scotton, 2005). Even in the United States, which is a relatively monolingual society, more than 47 million people speak a language other than English at home, and about 10 million of these people were children or youths in public schools (United States Department of Commerce, 2003). The large majority of bilingual students (75 per cent) are Hispanic, but the rest represent more than a hundred different language groups from around the world. In larger communities throughout the United States, it is therefore common for a single classroom to contain students from several language backgrounds at once.
In classrooms as in other social settings, bilingualism exists in different forms and degrees. At one extreme are students who speak both English and another language fluently; at the other extreme are those who speak only limited versions of both languages. In between are students who speak their home (or heritage) language much better than English, as well as others who have partially lost their heritage language in the process of learning English (Tse, 2001). Commonly, too, a student may speak a language satisfactorily, but be challenged by reading or writing it—though even this pattern has individual exceptions. Whatever the case, each bilingual student poses unique challenges to teachers.
Balanced or fluent bilingualism
The student who speaks both languages fluently has a definite cognitive advantage. As you might suspect and as research has confirmed, a fully fluent bilingual student is in a better position than usual to express concepts or ideas in more than one way, and to be aware of doing so (Jimenez, et al. 1995; Francis, 2006). The question: “What if a dog were called a cat?” is less likely to confuse even a very young bilingual child. Nor will the follow-up question: “Could the ‘cat’ meow?” confuse them. Such skill in reflecting on language is a form of metacognition, which I discussed in (Reference) Chapter 2 and defined as using language as an object of thought. Metacognition can be helpful for a variety of academic purposes, such as writing stories and essays, or interpreting complex text materials.
Unbalanced bilingualism
Unfortunately, the bilingualism of many students is “unbalanced” in the sense that they are either still learning English, or else they have lost some earlier ability to use their original, heritage language—or occasionally a bit of both. The first sort of student—sometimes called an English language learner (ELL) or limited English learner (LEL)—has received the greatest attention and concern from educators, since English is the dominant language of instruction and skill and obviously helps prepare a student for life in American society. ELL students essentially present teachers with this dilemma: how to respect the original language and culture of the student while also helping the student to join more fully in the mainstream—i.e. English-speaking—culture? Programs to address this question have ranged from total immersion in English from a young age (the “sink or swim” approach) to phasing in English over a period of several years (sometimes called an additive approach to bilingual education). In general, evaluations of bilingual programs have favored the more additive approaches (Beykont, 2002). Both languages are developed and supported, and students ideally become able to use either language permanently, though often for different situations or purposes. A student may end up using English in the classroom or at work, for example, but continue using Spanish at home or with friends, even though he or she is perfectly capable of speaking English with them.
Language loss
What about the other kind of imbalance, in which a student is acquiring English but losing ability with the student’s home or heritage language? This sort of bilingualism is quite common in the United States and other nations with immigrant populations (Tse, 2001). Imagine this situation: First-generation immigrants arrive, and they soon learn just enough English to manage their work and daily needs, but continue using their original language at home with family and friends from their former country. Their children, however, experience strong expectations and pressure to learn and use English, and this circumstance dilutes the children’s experience with the heritage language. By the time the children become adults, they are likely to speak and write English better than their heritage language, and may even be unable or unwilling to use the heritage language with their own children (the grandchildren of the original immigrants).
This situation might not at first seem like a problem for which we, as teachers, need to take responsibility, since the children immigrants, as students, are acquiring the dominant language of instruction. In fact, however, things are not that simple. Research finds that language loss limits students’ ability to learn English as well or as quickly as they otherwise can do. Having a large vocabulary in a first language, for example, has been shown to save time in learning vocabulary in a second language (Hansen, Umeda & McKinney, 2002). But students can only realize the savings if their first language is preserved. Preserving the first language is also important if a student has impaired skill in all languages and therefore needs intervention or help from a speech-language specialist. Research has found, in such cases, that the specialist can be more effective if the specialist speaks and uses the first language as well as English (Kohnert, et al., 2005). Generally, though also more indirectly, minimizing language loss helps all bilingual students’ education because preservation tends to enrich students’ and parents’ ability to communicate with each other. With two languages to work with, parents can stay “in the loop” better about their children’s educations and support the teacher’s work—for example, by assisting more effectively with homework (Ebert, 2005).
Note that in the early years of schooling, language loss can be minimized to some extent by the additive or parallel-track bilingual programs that I mentioned above. For a few years, though not forever, young students are encouraged to use both of their languages. In high school, in addition, some conventional foreign language classes—notably in Spanish—can be adjusted to include and support students who are already native speakers of the language alongside students who are learning it for the first time (Tse, 2001). But for heritage languages not normally offered as “foreign” languages in school, of course, this approach will not work. Such languages are especially at risk for being lost.
