Specially designed academic instruction in English

Last updated

Specially designed academic instruction in English (SDAIE) is a teaching approach intended for teaching various academic content (such as social studies, science or literature) using the English language to students who are still learning English. SDAIE requires the student possess intermediate fluency in English as well as mastery of their native language. The instruction is carefully prepared so the student can access the English language content supported by material in their primary language and carefully planned instruction that strives for comprehensible input. SDAIE is a method of teaching students in English in such a manner that they gain skills in both the subject material and in using English.

English language West Germanic language

English is a West Germanic language that was first spoken in early medieval England and eventually became a global lingua franca. Named after the Angles, one of the Germanic tribes that migrated to the area of Great Britain that would later take their name, England, both names ultimately deriving from the Anglia peninsula in the Baltic Sea. It is closely related to Frisian and Low Saxon, and its vocabulary has been significantly influenced by other Germanic languages, particularly Norse, and to a greater extent Latin and French.

SDAIE is not an English-only submersion program where the student is dependent solely on English, nor is it a watered down curriculum. SDAIE is an approach that seeks to teach both content and language in a cognitively demanding environment. As such, it is an important aspect of some structured English immersion programs. Lessons thus include both content goals and language goals for the students.

Preparing good lessons in SDAIE require awareness that the student is not a native English speaker and avoidance of those aspects of English that might make it difficult for a person learning English as a second language. This includes avoiding idiomatic English, which may seem natural to a native speaker but would confuse non-native speakers.

Idiom combination of words that has a figurative meaning

An idiom is a phrase or an expression that has a figurative, or sometimes literal, meaning. Categorized as formulaic language, an idiom's figurative meaning is different from the literal meaning. There are thousands of idioms, occurring frequently in all languages. It is estimated that there are at least twenty-five thousand idiomatic expressions in the English language.

Features of SDAIE

Low affective filter

Modified speech

A vocabulary is a set of familiar words within a person's language. A vocabulary, usually developed with age, serves as a useful and fundamental tool for communication and acquiring knowledge. Acquiring an extensive vocabulary is one of the largest challenges in learning a second language.

Contextual clues

Gesture form of non-verbal communication or non-vocal communication

A gesture is a form of non-verbal communication or non-vocal communication in which visible bodily actions communicate particular messages, either in place of, or in conjunction with, speech. Gestures include movement of the hands, face, or other parts of the body. Gestures differ from physical non-verbal communication that does not communicate specific messages, such as purely expressive displays, proxemics, or displays of joint attention. Gestures allow individuals to communicate a variety of feelings and thoughts, from contempt and hostility to approval and affection, often together with body language in addition to words when they speak.

Facial expression motions or positions of subcutaneous human face muscles, conveying emotional state

A facial expression is one or more motions or positions of the muscles beneath the skin of the face. According to one set of controversial theories, these movements convey the emotional state of an individual to observers. Facial expressions are a form of nonverbal communication. They are a primary means of conveying social information between humans, but they also occur in most other mammals and some other animal species.

According to the semantic analysis of Geoffrey Leech, the associative meaning of an expression has to do with individual mental understandings of the speaker. They, in turn, can be broken up into five sub-types: connotative, collocative, social, affective and reflected.

Multisensory experiences

In education, realia are objects from real life used in classroom instruction by educators to improve students' understanding of other cultures and real life situations. A teacher of a foreign language often employs realia to strengthen students' associations between words for common objects and the objects themselves. In many cases, these objects are part of an instructional kit which includes a manual and is thus considered as being part of a documentary whole by librarians.

Experiential learning

Experiential learning is the process of learning through experience, and is more specifically defined as "learning through reflection on doing". Hands-on learning is a form of experiential learning but does not necessarily involve students reflecting on their product. Experiential learning is distinct from rote or didactic learning, in which the learner plays a comparatively passive role. It is related to, but not synonymous with, other forms of active learning such as action learning, adventure learning, free-choice learning, cooperative learning, service-learning, and situated learning.

Language education refers to the process and practice of acquiring a second or foreign language. It is primarily a branch of applied linguistics, however can be considered an interdisciplinary field. There are four main learning categories for language education: communicative competencies, proficiencies, cross-cultural experiences, and multiple literacies.

English as a second or foreign language is the use of English by speakers with different native languages. Language education for people learning English may be known as English as a second language (ESL), English as a foreign language (EFL), English as an additional language (EAL), or English for speakers of other languages (ESOL). The aspect in which ESL is taught is called teaching English as a foreign language (TEFL).

TPR Storytelling is a method of teaching foreign languages. TPRS lessons use a mixture of reading and storytelling to help students learn a foreign language in a classroom setting. The method works in three steps: in step one the new vocabulary structures to be learned are taught using a combination of translation, gestures, and personalized questions; in step two those structures are used in a spoken class story; and finally, in step three, these same structures are used in a class reading. Throughout these three steps, the teacher will use a number of techniques to help make the target language comprehensible to the students, including careful limiting of vocabulary, constant asking of easy comprehension questions, frequent comprehension checks, and very short grammar explanations known as "pop-up grammar". Many teachers also assign additional reading activities such as free voluntary reading, and there have been several easy novels written by TPRS teachers for this purpose.

Communicative language teaching (CLT), or the communicative approach, is an approach to language teaching that emphasizes interaction as both the means and the ultimate goal of study.

Reading comprehension

It means Strategies of reading

Sheltered instruction is an approach to teaching English language learners which integrates language and content instruction. The phrase "sheltered instruction," original concept, and underlying theory of comprehensible input are all credited to Stephen Krashen.

A lesson plan is a teacher's detailed description of the course of instruction or "learning trajectory" for a lesson. A daily lesson plan is developed by a teacher to guide class learning. Details will vary depending on the preference of the teacher, subject being covered, and the needs of the students. There may be requirements mandated by the school system regarding the plan. A lesson plan is the teacher's guide for running a particular lesson, and it includes the goal, how the goal will be reached and a way of measuring how well the goal was reached.

The audio-lingual method, Army Method, or New Key, is a style of teaching used in teaching foreign languages. It is based on behaviorist theory, which postulates that certain traits of living things, and in this case humans, could be trained through a system of reinforcement. The correct use of a trait would receive positive feedback while incorrect use of that trait would receive negative feedback.

Task-based language teaching (TBLT), also known as task-based instruction (TBI), focuses on the use of authentic language and on asking students to do meaningful tasks using the target language. Such tasks can include visiting a doctor, conducting an interview, or calling customer service for help. Assessment is primarily based on task outcome rather than on accuracy of prescribed language forms. This makes TBLT especially popular for developing target language fluency and student confidence. As such TBLT can be considered a branch of communicative language teaching (CLT).

An English language learner is a term used in some English-speaking countries such as the US and Canada to describe a person who is learning the English language in addition to his or her native language or any other languages they may speak. The instruction and assessment of students, their cultural background, and the attitudes of classroom teachers towards ELLs have all been found to be factors in ELL student achievement. Some ways that have been suggested to assist ELLs include bringing their home cultures into the classroom, involving them in language-appropriate content-area instruction from the beginning, and by integrating literature into the learning program. Some educational advocates, especially in the United States, prefer for a student learning any second language the term emergent bilingual.

Language teaching, like other educational activities, may employ specialized vocabulary and word use. This list is a glossary for English language learning and teaching using the communicative approach.

Content-based instruction (CBI) is a significant approach in language education, designed to provide second-language learners instruction in content and language.

Fluency is the property of a person or of a system that delivers information quickly and with expertise.

The input hypothesis, also known as the monitor model, is a group of five hypotheses of second-language acquisition developed by the linguist Stephen Krashen in the 1970s and 1980s. Krashen originally formulated the input hypothesis as just one of the five hypotheses, but over time the term has come to refer to the five hypotheses as a group. The hypotheses are the input hypothesis, the acquisition–learning hypothesis, the monitor hypothesis, the natural order hypothesis and the affective filter hypothesis. The input hypothesis was first published in 1977.

Language pedagogy may take place as a general school subject, in a specialized language school, or out of school with a rich selection of proprietary methods online and in books, CDs and DVDs. There are many methods of teaching languages. Some have fallen into relative obscurity and others are widely used; still others have a small following, but offer useful insights.

Differentiated instruction and assessment, also known as differentiated learning or, in education, simply, differentiation, is a framework or philosophy for effective teaching that involves providing all students within their diverse classroom community of learners a range of different avenues for understanding new information in terms of: acquiring content; processing, constructing, or making sense of ideas; and developing teaching materials and assessment measures so that all students within a classroom can learn effectively, regardless of differences in ability. Students vary in culture, socioeconomic status, language, gender, motivation, ability/disability, personal interests and more, and teachers must be aware of these varieties as they plan curriculum. By considering varied learning needs, teachers can develop personalized instruction so that all children in the classroom can learn effectively. Differentiated classrooms have also been described as ones that respond to student variety in readiness levels, interests and learning profiles. It is a classroom that includes all students and can be successful. To do this, a teacher sets different expectations for task completion for students based upon their individual needs.

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.

The natural approach is a method of language teaching developed by Stephen Krashen and Tracy Terrell in the late 1970s and early 1980s. It aims to foster naturalistic language acquisition in a classroom setting, and to this end it emphasises communication, and places decreased importance on conscious grammar study and explicit correction of student errors. Efforts are also made to make the learning environment as stress-free as possible. In the natural approach, language output is not forced, but allowed to emerge spontaneously after students have attended to large amounts of comprehensible language input.

A flipped classroom is an instructional strategy and a type of blended learning that reverses the traditional learning environment by delivering instructional content, often online, outside of the classroom. It moves activities, including those that may have traditionally been considered homework, into the classroom. In a flipped classroom, students watch online lectures, collaborate in online discussions, or carry out research at home while engaging in concepts in the classroom with the guidance of a mentor.

Language power (LP) is a measure of one’s ability to communicate effectively in a given language, specifically one that is not native to the speaker.
