Bilingual education

Bilingual education is a teaching method where students learn using two or more languages. This is not the same as taking a single language class. In these programs, both languages are used to teach core subjects like math, science, and history. The primary goal is to help students achieve fluency and literacy in both languages. Teachers use various strategies to reach this goal. One method is called translanguaging, which allows students to use all their linguistic knowledge to support learning. Another method is recasting, where a teacher repeats a student's statement with correct grammar.

There are several different models of bilingual education. These are often categorized by their ultimate end goal for the student. Maintenance bilingual education programs aim to keep both languages active for most of a student's schooling. The goal is for students to graduate capable of discussing any subject in either language. One form is the dual language immersion program. These classrooms contain a mix of native speakers from different language backgrounds. Some use a 90/10 model, where 90% of instruction is in the native language at first. Over time, the amount of the second language increases until it is equal. Another option is the 50/50 model, which uses an even split from the start.

Other maintenance models include developmental or late-exit programs. In these programs, all students usually share the same native language. They often follow a gradual transition from their home language to a balanced split. There are also bimodal-bilingual programs. These are common in schools for deaf or hard of hearing students. In these settings, students learn using two different modalities. This usually means one spoken or written language and one signed language. These programs ensure that communication is accessible through different sensory paths.

Transitional bilingual education is another major model. This is often called an early-exit program. The goal is to use the student's native language so they do not fall behind in subjects like science or math. This approach relies on the common underlying proficiency model. This theory suggests that skills learned in a native language can transfer to a second language. Once a student becomes proficient in the new language, they move to single-language classrooms. In the United States, this is a very common approach. It accounts for about 60% of state and locally funded programs.

It is important to distinguish bilingual education from English as a Second Language (ESL) programs. ESL programs are not considered bilingual education. Their goal is to help learners acquire English, not to achieve bi-literacy in two languages. ESL is a supplementary program common in many English-speaking countries. One common method used in ESL is sheltered English instruction, or SEI. Bilingual education is growing in popularity in the United States. For example, California had 2,363,000 Dual Language Learners in 2022. This number represented 32% of all children aged 0 to 8 in that state.

Bilingual education offers many benefits for students and society. It can lead to more employment options and better intercultural communication. It can also support minority language speakers by valuing their heritage. This can lead to increased self-esteem and better school attendance. Research shows that bilingual students may have higher reading scores. This might be because they have a better awareness of different writing systems. Some studies even look at the "bilingual brain." Early exposure to multiple languages seems to maximize these benefits. Preschoolers in these programs show brain activation patterns similar to adults learning a second language.

Finally, bilingual education can help with language revitalization. This is when communities work to save endangered languages. These languages are often tied to a community's identity and culture. In the past, some policies were very harmful. For instance, residential schools in Canada punished children for speaking their mother tongues. This caused great trauma for many Indigenous people. Today, new programs help re-awaken these languages. In New Zealand, the Māori community created the Te Kōhanga Reo program. This program uses traditional customs and native speakers to help the language adapt to modern times. These efforts help communities protect their history and their future.
