In bilingual education, students are taught in two languages. It is distinct from learning a second language as a subject because both languages are used for instruction in different content areas like math, science, and history. The time spent in each language depends on the model. For example, some models focus on providing education in both languages throughout a student's entire education while others gradually transition to education in only one language. The ultimate goal of bilingual education is fluency and literacy in both languages through a variety of strategies such as translanguaging and recasting.
Language education – the process and practice of teaching a second or foreign language – is primarily a branch of applied linguistics, but can be an interdisciplinary field. There are four main learning categories for language education: communicative competencies, proficiencies, cross-cultural experiences, and multiple literacies.
A vocabulary is a set of words, typically the set in a language or the set known to an individual. The word vocabulary originated from the Latin vocabulum, meaning "a word, name". It forms an essential component of language and communication, helping convey thoughts, ideas, emotions, and information. Vocabulary can be oral, written, or signed and can be categorized into two main types: active vocabulary and passive vocabulary. An individual's vocabulary continually evolves through various methods, including direct instruction, independent reading, and natural language exposure, but it can also shrink due to forgetting, trauma, or disease. Furthermore, vocabulary is a significant focus of study across various disciplines, like linguistics, education, psychology, and artificial intelligence. Vocabulary is not limited to single words; it also encompasses multi-word units known as collocations, idioms, and other types of phraseology. Acquiring an adequate vocabulary is one of the largest challenges in learning a second language.
A heritage language is a minority language learned by its speakers at home as children, and difficult to be fully developed because of insufficient input from the social environment. The speakers grow up with a different dominant language in which they become more competent. Polinsky and Kagan label it as a continuum that ranges from fluent speakers to barely speaking individuals of the home language. In some countries or cultures which determine a person's mother tongue by the ethnic group they belong to, a heritage language would be linked to the native language.
Language immersion, or simply immersion, is a technique used in bilingual language education in which two languages are used for instruction in a variety of topics, including math, science, or social studies. The languages used for instruction are referred to as the L1 and the L2 for each student, with L1 being the student's native language and L2 being the second language to be acquired through immersion programs and techniques. There are different types of language immersion that depend on the age of the students, the classtime spent in L2, the subjects that are taught, and the level of participation by the speakers of L1.
Second-language acquisition (SLA), sometimes called second-language learning—otherwise referred to as L2acquisition, is the process by which people learn a second language. Second-language acquisition is also the scientific discipline devoted to studying that process. The field of second-language acquisition is regarded by some but not everybody as a sub-discipline of applied linguistics but also receives research attention from a variety of other disciplines, such as psychology and education.
Sheltered instruction is an educational approach designed to make academic content more accessible to English language learners (ELLs) while promoting their language development. It involves modifying instruction to accommodate students' language proficiency levels and providing additional support to help comprehend and engage with material effectively.
Sequential bilingualism occurs when a person becomes bilingual by first learning one language and then another. The process is contrasted with simultaneous bilingualism, in which both languages are learned at the same time.
Language attrition is the process of decreasing proficiency in or losing a language. For first or native language attrition, this process is generally caused by both isolation from speakers of the first language ("L1") and the acquisition and use of a second language ("L2"), which interferes with the correct production and comprehension of the first. Such interference from a second language is likely experienced to some extent by all bilinguals, but is most evident among speakers for whom a language other than their first has started to play an important, if not dominant, role in everyday life; these speakers are more likely to experience language attrition. It is common among immigrants that travel to countries where languages foreign to them are used. Second language attrition can occur from poor learning, practice, and retention of the language after time has passed from learning. This often occurs with bilingual speakers who do not frequently engage with their L2.
Catherine Elizabeth Snow is an educational psychologist and applied linguist. In 2009 Snow was appointed to the Patricia Albjerg Graham Professorship in the Harvard Graduate School of Education, having previously held the Henry Lee Shattuck Professorship also in the Harvard Graduate School of Education. Snow is past president of the American Educational Research Association (2000–2001). She chaired the RAND Corporation 'reading study group' from 1999.
English-language learner is a term used in some English-speaking countries such as the United States and Canada to describe a person who is learning the English language and has a native language that is not English. Some educational advocates, especially in the United States, classify these students as non-native English speakers or emergent bilinguals. Various other terms are also used to refer to students who are not proficient in English, such as English as a second language (ESL), English as an additional language (EAL), limited English proficient (LEP), culturally and linguistically diverse (CLD), non-native English speaker, bilingual students, heritage language, emergent bilingual, and language-minority students. The legal term that is used in federal legislation is 'limited English proficient'.
The critical period hypothesis or sensitive period hypothesis claims that there is an ideal time window of brain development to acquire language in a linguistically rich environment, after which further language acquisition becomes much more difficult and effortful. It is the subject of a long-standing debate in linguistics and language acquisition over the extent to which the ability to acquire language is biologically linked to developmental stages of the brain. The critical period hypothesis was first proposed by Montreal neurologist Wilder Penfield and co-author Lamar Roberts in their 1959 book Speech and Brain Mechanisms, and was popularized by Eric Lenneberg in 1967 with Biological Foundations of Language.
Extensive reading (ER) is the process of reading longer, easier texts for an extended period of time without a breakdown of comprehension, feeling overwhelmed, or the need to take breaks. It stands in contrast to intensive or academic reading, which is focused on a close reading of dense, shorter texts, typically not read for pleasure. Though used as a teaching strategy to promote second-language development, ER also applies to free voluntary reading and recreational reading both in and out of the classroom. ER is based on the assumption that we learn to read by reading.
Heritage language learning, or heritage language acquisition, is the act of learning a heritage language from an ethnolinguistic group that traditionally speaks the language, or from those whose family historically spoke the language. According to a commonly accepted definition by Valdés, heritage languages are generally minority languages in society and are typically learned at home during childhood. When a heritage language learner grows up in an environment with a dominant language that is different from their heritage language, the learner appears to be more competent in the dominant language and often feels more comfortable speaking in that language. "Heritage language" may also be referred to as "community language", "home language", and "ancestral language".
Paul Nation is an internationally recognized scholar in the field of linguistics and teaching methodology. As a professor in the field of applied linguistics with a specialization in pedagogical methodology, he has been able to create a language teaching framework to identify key areas of language teaching focus. Paul Nation is best known for this framework, which has been labelled The Four Strands. He has also made notable contributions through his research in the field of language acquisition that focuses on the benefits of extensive reading and repetition as well as intensive reading. Nation's numerous contributions to the linguistics research community through his published work has allowed him to share his knowledge and experience so that others may adopt and adapt it. He is credited with bringing « legitimization to second language vocabulary researches » in 1990.
Second-language acquisition classroom research is an area of research in second-language acquisition concerned with how people learn languages in educational settings. There is a significant overlap between classroom research and language education. Classroom research is empirical, basing its findings on data and statistics wherever possible. It is also more concerned with what the learners do in the classroom than with what the teacher does. Where language teaching methods may only concentrate on the activities the teacher plans for the class, classroom research concentrates on the effect the things the teacher does has on the students.
Social media language learning is a method of language acquisition that uses socially constructed Web 2.0 platforms such as wikis, blogs, and social networks to facilitate learning of the target language. Social media is used by language educators and individual learners that wish to communicate in the target language in a natural environment that allows multimodal communication, ease of sharing, and possibilities for feedback from peers and educators.
Translanguaging is a term that can refer to different aspects of multilingualism. It can describe the way bilinguals and multilinguals use their linguistic resources to make sense of and interact with the world around them. It can also refer to a pedagogical approach that utilizes more than one language within a classroom lesson. The term "translanguaging" was coined in the 1980s by Cen Williams in his unpublished thesis titled “An Evaluation of Teaching and Learning Methods in the Context of Bilingual Secondary Education.” Williams used the term to describe the practice of using two languages in the same lesson, which differed from many previous methods of bilingual education that tried to separate languages by class, time, or day. In addition, Vogel and Garcia argued that translanguaging theory posits that rather than possessing two or more autonomous language systems, as previously thought when scholars described bilingual or multilingual speakers, bilinguals and multilingual speakers select and deploy their languages from a unitary linguistic repertoire. However, the dissemination of the term, and of the related concept, gained traction decades later due in part to published research by Ofelia García, among others. In this context, translanguaging is an extension of the concept of languaging, the discursive practices of language speakers, but with the additional feature of using multiple languages, often simultaneously. It is a dynamic process in which multilingual speakers navigate complex social and cognitive demands through strategic employment of multiple languages.
In linguistics, the term near-native speakers is used to describe speakers who have achieved "levels of proficiency that cannot be distinguished from native levels in everyday spoken communication and only become apparent through detailed linguistic analyses" (p. 484) in their second language or foreign languages. Analysis of native and near-native speakers indicates that they differ in their underlying grammar and intuition, meaning that they do not interpret grammatical contrasts the same way. However, this divergence typically does not impact a near-native speaker's regular usage of the language.
Vocabulary learning is the process acquiring building blocks in second language acquisition Restrepo Ramos (2015). The impact of vocabulary on proficiency in second language performance "has become […] an object of considerable interest among researchers, teachers, and materials developers". From being a "neglected aspect of language learning" vocabulary gained recognition in the literature and reclaimed its position in teaching. Educators shifted their attention from accuracy to fluency by moving from the Grammar translation method to communicative approaches to teaching. As a result, incidental vocabulary teaching and learning became one of the two major types of teaching programs along with the deliberate approach.
