二语习得(L1)
二语习得
Labov:
• Competence is heterogeneous • Propose a sociolinguistic model dealing with the situationinduced variability of language use
Five Principals:
• All speakers possess several “styles” and adapt their speech to make it fit the social context • Styles can be ranged along a single dimension,measured by the amount of attention paid to speech. Speech varies as the speaker monitors it with different amounts of attention depending on the situation
• For instance, a professor may pay
close attention to his speech to make it vernacular and easy for the students to understand.
• If you want to study the way AfroAmerican boys talk on the street, for example, but you interview a boy in a clean office room of the school, you will not be able to obtain much information

SLA_二语习得重要问题总结
SLA 期末考试提纲Week 9Chapter 1 Introducing Second Language AcquisitionChapter 2 Foundations of Second Language AcquisitionPART ONE: Definition:1.Second Language Acquisition (SLA): a term that refers both to the study of individuals and groups who are learning a language subsequent to learning their first one as young children, and to the process of learning that language.2.Formal L2 learning: instructed learning that takes place in classrooms.rmal L2 learning: SLA that takes place in naturalistic contexts.4.First language/native language/mother tongue (L1): A language that is acquired naturally in early childhood, usually because it is the primary language of a child’s family. A child who grows up in a multilingual setting may have more than one “first” language.5.Second language (L2): In its general sense, this term refers to any language that is acquired after the first language has been established. In its specific sense, this term typically refers to an additional language which is learned within a context where it is societally dominant and needed for education, employment, and other basic purposes. The more specific sense contrasts with foreign language, library language, auxiliary (帮助的，辅助的) language, and language for specific purposes.6.Target language: The language that is the aim or goal of learning.7.Foreign language: A second language that is not widely used in the learners’ immediate social context, but rather one that might be used for future travel or other cross-cultural communication situations, or one that might be studied as a curricular requirement or elective in school with no immediate or necessary practical application.8.Library language: A second language that functions as a tool for further learning, especially when books and journals in a desired field of study are not commonly published in the learner’s L1.9.Auxiliary language: A second language that learners need to know for some official functions in their immediate sociopolitical setting. Or that they will need for purposes of wider communication, although their first language serves most other needs in their lives.10.Linguistic competence: The underlying knowledge that speakers/hearers have of a language. Chomsky distinguishes this from linguistic performance.11.Linguistic performance: The use of language knowledge in actual production.municative competence: A basic tenet (原则、信条、教条) of sociolinguistics defined as “what a speaker needs to know to communicate appropriately within a particular language community” (Saville-Troike 2003)13.Pragmatic competence: Knowledge that people must have in order to interpret and convey meaning within communicative situations.14.Multilingualism: The ability to use more than one language.15.Monolingualism: The ability to use only one language.16.Simultaneous multilingualism: Ability to use more than one language that were acquired during early childhood.17.Sequential multilingualism: Ability to use one or more languages that were learned after L1 had already been established.18.Innate capacity: A natural ability, usually referring to children’s natural ability to learn or acquire language.19.Child grammar: Grammar of children at different maturational levels that is systematic in terms of production and comprehension.20.Initial state: The starting point for language acquisition; it is thought to include the underlying knowledge about language structures and principles that are in learners’ heads at the very start of L1 or L2 acquisition.21.Intermediate state: It includes the maturational changes which take place in “child grammar”, and the L2 developmental sequence which is known as learner language.22.Final state: The outcome of L1 and L2 leaning, also known as the stable state of adult grammar.23.Positive transfer: Appropriate incorporation of an L1 structure or rule in L2 structure.24.Negative transfer: Inappropriate influence of an L1 structure or rule on L2 use. Also called interference.25.Poverty-of-the-stimulus: The argument that because language input to children is impoverished and they still acquire L1, there must be an innate capacity for L1 acquisition.26.Structuralism: The dominant linguistic model of the 1950s, which emphasized the description of different levels of production in speech.27.Phonology: The sound systems of different languages and the study of such systems generally.28.Syntax: The linguistic system of grammatical relationships of words within sentences, such as ordering and agreement.29.Semantics: The linguistic study of meaning.30.Lexicon: The component of language that is concerned with words and their meanings.31.Behaviorism: The most influential cognitive framework applied to language learning in the 1950s. It claims that learning is the result of habit formation.32.Audiolingual method: An approach to language teaching that emphasizes repetition and habit formation. This approach was widely practiced in much of the world until at least the 1980s.33.Transformational-Generative Grammar: The first linguistic framework with an internal focus, which revolutionized linguistic theory and had profound effect on both the study of first and second languages. Chomsky arguedeffectively that the behaviorist theory of language acquisition is wrong because it cannot explain the creative aspects of linguistic ability. Instead, humans must have some innate capacity for language.34.Principles and Parameters (model): The internally focused linguistic framework that followed Chomsky’s Transformational-Generative Grammar. It revised specifications of what constitutes innate capacity to include more abstract notions of general principles and constraints common to human language as part of a Universal Grammar.35.Minimalist program: The internally focused linguistic framework that followed Chomsky’s Principles and Parameters model.This framework adds distinctions between lexical and functional category development, as well as more emphasis on the acquisition of feature specification as a part of lexical knowledge.36.Functionalism: A linguistic framework with an external focus that dates back to the early twentieth century and has its roots in the Prague School (布拉格学派) of Eastern Europe. It emphasizes the information content of utterances and considers language primarily as a system of communication. Functionalist approaches have largely dominated European study of SLA and are widely followed elsewhere in the world.37.Neurolinguistics: The study of the location and representation of language in the brain, of interest to biologists and psychologists since the nineteenth century and one of the first fields to influence cognitive perspectives on SLA when systematic study began in 1960s.38.Critical period: The limited number of years during which normal L1 acquisition is possible.39.Critical Period Hypothesis: The claim that children have only a limited number of years during which they can acquire their L1 flawlessly; if they suffered brain damage to the language areas, brain plasticity in childhood would allow other areas of the brain to take over the language functions of the damaged areas, but beyond a certain age, normal language development would not be possible. This concept is commonly extended to SLA as well, in the claim that only children are likely to achieve native or near-native proficiency in L2.rmation processing (IP): A cognitive framework which assumes that SLA (like learning of other complex domains) proceeds from controlled to automatic processing and involves progressive reorganization of knowledge.41.Connectionism: A cognitive framework for explaining learning processes, beginning in the 1980s and becoming increasingly influential. It assumes that SLA results from increasing strength of associations between stimuli and responses.42.Variation theory: A microsocial framework applied to SLA that explores systematic differences in learner production which depend on contexts of use.43.Accommodation theory: A framework for study of SLA that is based on the notion that speakers usually unconsciously change their pronunciation and even the grammatical complexity of sentences they use to sound more like whomever they are talking to.44.Sociocultural theory (SCT): An approach established by Vygotsky which claims that interaction not only facilitates language learning but is a causative force in acquisition. Further, all of learning is seen as essentially a social process which is grounded in sociocultural settings.45.Ethnography(人种论、民族志) of communication: A framework for analysis of language and its functions that was established by Hymes(1966). It relates language use to broader social and cultural contexts, and applies ethnographic methods of data collection and interpretation to study of language acquisition and use.46.Acculturation(文化适应): Learning the culture of the L2 community and adapting to those values and behavior patterns.47.Acculturation Model/Theory: Schumann’s (1978) theory that identifies group factors such as identity and status which determine social and psychological distance between learner and target language populations. He claims these influence outcomes of SLA.48.Social psychology: A societal approach in research and theory that allows exploration of issues such as how identity, status, and values influence L2 outcomes and why. It has disciplinary ties to both psychological and social perspectives. PART TWO: Short & Long answers:Chapter 11.What are the similarities and differences between linguists, psycholinguist, sociolinguists and social psycholinguists? P3（1）Linguists emphasize the characteristics of the differences and similarities in the languages that are being learned, and thelinguistic competence (underlying knowledge) and linguistic performance (actual production) of learners at various stages of acquisition.（2）Psychologists emphasize the mental or cognitive processes involved in acquisition, and the representation of languages in the brain.（3）Sociolinguists emphasize variability in learner linguistic performance, and extend the scope of study to communicative competence(underlying knowledge that additionally accounts for language use, or pragmatic competence).（4）Social psychologists emphasize group-related phenomena, such as identity and social motivation, and the interactional and larger social contexts of learning.2.What are the differences between second language, foreign language, library language and auxiliary language? P4（1）A second language is typically an official or societally dominant language needed for education, employment, and other basic purposes. It is often acquired by minority group members or immigrants who speak another language natively. In this more restricted sense, the term is contrasted with other terms in this list.（2）A foreign language is one not widely used in the learners' immediate social context which might be used for future travel or other cross-cultural communication situations, or studied as a curricular requirement or elective in school, but with no immediate or necessary practical application.（3）A library language is one which functions primarily as a tool for future learning through reading, especially when books or journals in a desired field of study are not commonly published in the learners' native tongue.（4）An auxiliary language is one which learners need to know for some official functions in their immediate political setting, or will need for purposes of wider communication, although their first language serves most other needs in their lives.3.Why are some learners more (or less) successful than other? P5The intriguing question of why some L2 learners are more successful than others requires us to unpack the broad label “learners” for some dimensions of discussion. Linguistics may distinguish categories of learners defined by the identity and relationship of their L1 and L2; psycholinguists may make distinctions based on individual aptitude for L2 learning, personality factors, types and strength of motivation, and different learning strategies; sociolinguists may distinguish among learners with regard to social, economic, and political differences and learner experiences in negotiated interaction; and social psychologists may categorize learners according to aspects of their group identity and attitudes toward targetlanguage speakers or toward L2 learning itself.Chapter21.List at least five possible motivations for learning a second language at an older age. P10The motivation may arise from a variety of conditions, including the following:Invasion or conquest of one’s country by speakers of another language;A need or desire to contact speakers of other languages ineconomic or other specific domains;Immigration to a country where use of a language other than one's L1 is required;Adoption of religious beliefs and practices which involve use of another language;A need or desire to pursue educational experienceswhere access requires proficiency in another language;A desire for occupational or social advancement whichis furthered by knowledge of another language;An interest in knowing more about peoples of other cultures and having access to their technologies or literatures.2.What are the two main factors that influence the language learning? P13（1）The role of natural ability: Humans are born with a natural ability or innate capacity to learn language.（2）The role of social experience: Not all of L1 acquisition can be attributed to innate ability, for language-specific learning also plays a crucial role. Even if the universal properties of language are preprogrammed in children, they must learn all of those features which distinguish their L1 from all other possible human languages. Children will never acquire such language-specific knowledge unless that language is used with them and around them, and they will learn to use only the language(s) used around them, no matter what their linguistic heritage. American-born children of Korean or Greek ancestry will never learn the language of their grandparents if only English surrounds them, for instance, and they will find their ancestral language just as hard to learn as any other English speakers do if they attempt to learn it as an adult. Appropriate social experience, including L1 input and interaction, is thus a necessary condition for acquisition.3.What is the initial state of language development for L1 and L2 respectively? P17-18The initial state of L1 learning is composed solely of an innate capacity for language acquisition which may or may not continue to be available for L2, or may be available only in some limited ways. The initial state for L2 learning, on the other hand, has resources of L1 competence, world knowledge, and established skills for interaction, which can be both an asset and an impediment.4.How does intermediate states process? P18-19The cross-linguistic influence, or transfer of prior knowledge from L1 to L2, is one of the processes that is involved ininterlanguage development. Two major types of transfer which occur are: (1) positive transfer, when an L1 structure or rule is used in an L2 utterance and that use is appropriate or “correct” in the L2; and (2) negative transfer (or interference), when an L1 structure or rule is used in an L2 utterance and that use is inappropriate and considered an “error”.5.What is a necessary condition for language learning (L1 or L2)? P20Language input to the learner is absolutely necessary for either L1 or L2 learning to take place. Children additionally require interaction with other people for L1 learning to occur. It is possible for some individuals to reach a fairly high level of proficiency in L2 even if they have input only from such generally non-reciprocal sources as radio, television, or written text.6.What is a facilitating condition for language learning? P20While L1 learning by children occurs without instruction, and while the rate of L1 development is not significantly influenced by correction of immature forms or by degree of motivation to speak, both rate and ultimate level of development in L2 can be facilitated or inhabited by many social and individual factors, such as (1) feedback, including correction of L2 learners' errors; (2) aptitude, including memory capacity and analytic ability; (3) motivation, or need and desire to learn; (4) instruction, or explicit teaching in school settings.7.Give at least 2 reasons that many scientists believe in someinnate capacity for language. P21-24The notion that innate linguistic knowledge must underlie （指原则、理由构成某学说...的基础，潜在于...之下)language acquisition was prominently espoused (采纳或支持事业理念)by Noam Chomsky. This view has been supported by arguments such as the following:(1)Children’s knowledge of language goes beyond what could be learned from the input they receive: Children often hear incomplete or ungrammatical utterances along with grammatical input, and yet they are somehow able to filter the language they hear so that the ungrammatical input is not incorporated into their L1 system. Further, children are commonly recipients of simplified input from adults, which does not include data for all of the complexities which are within their linguistic competence. In addition, children hear only a finite subset of possible grammatical sentences, and yet they are able to abstract general principles and constraints which allow them to interpret and produce an infinite number of sentences which they have never heard before.(2)Constraints and principles cannot be learned: Children’s access to general constraints and principles which govern language could account for the relatively short time ittakes for the L1 grammar to emerge, and for the fact that it does so systematically and without any “wild” divergences. This could be so because innate principles lead children to organize the input they receive only in certain ways and not others. In addition to the lack of negative evidence , constraints and principles cannot be learnt in part because children acquire a first language at an age when such abstractions are beyond their comprehension; constraints and principles are thus outside the realm of learning process which are related to general intelligence.(3)Universal patterns of development cannot be explained by language-specific input: In spite of the surface differences in input, there are similar patterns in child acquisition of any language in the world. The extent of this similarity suggests that language universals are not only constructs derived from sophisticated theories and analyses by linguists, but also innate representations in every young child’s mind.8.Linguists have taken an internal and/or external focus to the study of language acquisition. What is the difference between the two? P25-26Internal focus emphasizes that children begin with an innate capacity which is biologically endowed, as well as the acquisition of feature specification as a part of lexical knowledge; while external focus emphasizes the information content of utterances, and considers language primarily as a system of communication.9.What are the two main factors for learning process in the study of SLA from a psychological perspective? P26-27(1) Information Processing, which assumes that L2 is a highly complex skill, and that learning L2 is not essentially unlike learning other highly complex skills. Processing itself is believed to cause learning;(2) Connectionism, which does not consider language learning to involve either innate knowledge or abstraction of rules and principles, but rather to result from increasing strength of associations (connections) between stimuli and responses.10.What are the two foci for the study of SLA from the social perspective? P27(1) Microsocial focus: the concerns within the microsocial focus relate to language acquisition and use in immediate social contexts of production, interpretation, and interaction. (2) Macrosocial focus: the concerns of the macrosocial focus relate language acquisition and use to broader ecological contexts, including cultural, political, and educational settings.Week10Chapter 5 Social contexts of Second Language AcquisitionPART ONE: Definitionmunicative competence: A basic tenet of sociolinguistics defined as “what a speaker needs to know to communicate appropriately within a particular language community”(Saville-Troike 2003)nguage community: A group of people who share knowledge of a common language to at least some extent.3.Foreigner talk: Speech from L1 speakers addressed to L2 learners that differs in systematic ways from language addressed to native or very fluent speakers.4.Direct Correction: Explicit statements about incorrect language use.5.Indirect correction: Implicit feedback about inappropriate language use, such as clarification requests when the listener has actually understood an utterance.6.Interaction Hypothesis: The claim that modifications and collaborative efforts which take place in social interation facilitate SLA because they contribute to the accessibility of input for mental processing.7.Symbolic mediation: A link between a person’s current mental state and higher order functions that is provided primarily by language; considered the usual route to learning (oflanguage, and of learning in general). Part of Vygosky’s Sociocultural Theory.8.Variable features: Multiple linguistic forms (vocabulary, phonology, morphology, syntax, discourse) that are systematically or predictably used by different speakers of a language, or by the same speakers at different times, with the same meaning or function.9.Linguistic context: Elements of language form and function associated with the variable element.10.Psychological context: factors associated with the amount of attention which is being given to language form during production, the level of automaticity versus control in processing, or the intellectual demands of a particular task.11.Microsocial context: features of setting/situation and interaction which relate to communicative events within which language is being produced, interpreted, and negotiated.12.Accommodation theory: A framework for study of SLA that is based on the notion that speakers usually unconsciously change their pronunciation and even the grammatical complexity of sentences they use to sound more like whomever they are talking to .13.ZPD: Zone of Proximal Development, an area ofpotential development where the learner can only achieve that potential with assistance. Part of Vygosky’s Soci ocultural Theory.14.Scaffolding: Verbal guidance which an expert provides to help a learner perform any specific task, or the verbal collaboration of peers to perform a task which would be too difficult for any one of them in individual performance.15.Intrapersonal interaction: communication that occurs within an individual's own mind, viewed by Vygosky as a sociocultural phenomen.16.Interpersonal interaction: Communicative events and situations that occur between people.17.Social institutions:The systems which are established by law, custom, or practice to regulate and organize the life of people in public domains: e.g. politics, religion, and education.18.Acculturation: learning the culture of the L2 community and adapting to those values and behavioral patterns.19.Additive bilingualism: The result of SLA in social contexts where members of a dominant group learn the language of a minority without threat to their L1 competence or to their ethnic identity.20.Subtractive bilingualism: The result of SLA in socialcontexts where members of a minority group learn the dominant language as L2 and are more likely to experience some loss of ethnic identity and attrition of L1 skills—especially if they are children.21.Formal L2 learning: formal/instructed learning generally takes place in schools, which are social institutions that are established in accord with the needs, beliefs, values, and customs of their cultural settings.rmal L2 learning: informal/naturalistic learning generally takes place in settings where people contact—and need to interact with—speakers of another language.PART TWO: Short & Long answers1.what is the difference between monolingual and multilingual communicative competence?Differencese between monolingual and multilingual communicative competence are due in part to the different social functions of first and second language learning, and to the differences between learning language and learning culture.The differences of the competence between native speakers and nonative speakers include structural differences in the linguisitc system, different rules for usage in writing or conversation, andeven somewhat divergent meanings for the “same” lexical forms. Further, a multilingual speaker’s total communicative competence differs from that of a monolingual in including knowledge of rules for the appropriate choice of language and for switching between languages, given a particular social context and communicative purpose.2.what are the microsocial factors that affect SLA? P101-102a) L2 variation b) input and interaction c) interaction as the genesis of language3.What is the difference between linguistic & communicative competence (CC)?Linguistic competence- It was defined in 1965 by Chomsky as a speaker's underlying ability to produce grammatically correct expressions. Linguistic competence refers to knowledge of language. Theoretical linguistics primarily studies linguistic competence: knowledge of a language possessed by “an ideal speak-listener”.Communicative competence- It is a term in linguistics which refers to “what a speaker needs to know to communicate appropriately within a particular language community”, such as alanguage user's grammatical knowledge of syntax , morphology , phonology and the like, as well as social knowledge about how and when to use utterances appropriately.4.Why is CC in L1 different from L2?L1 learning for children is an integral part of their sociolization into their native language community. L2 learning may be part of second culture learning and adaptation, but the relationship of SLA to social and cultural learning differs greatly with circumstances.5.What is Accommodation Theory? How does this explain L2 variation?Accommodation theory: Speakers (usually unconsciously) change their pronunciation and even the grammatical complexity of sentences they use to sound more like whomever they are talking to. This accounts in part for why native speakers tend to simply their language when they are talking to a L2 learner who is not fluent, and why L2 learners may acquire somewhat different varieties of the target language when they have different friends.6.Discuss the importance of input & interaction for L2 learning. How could this affect the feedback provided to students?ⅰ. a) From the perspective of linguistic approaches: (1) behaviorist: they consider input to form the necessary stimuli and feedback which learners respond to and imitate; (2) Universal Grammar: they consider exposure to input a necessary trigger for activating internal mechanisms; (3) Monitor Model: consider comprehensible input not only necessary but sufficient in itself to account for SLA;b) From the perspective of psychological approaches: (1) IP framework: consider input which is attended to as essential data for all stages of language processing; (2) connectionist framework: consider the quantity or frequency of input structures to largely determine acquisitional sequencing;c) From the perspective of social approaches: interaction is generally seen as essential in providing learners with the quantity and quality of external linguistic input which is required for internal processing.ⅱ. Other types of interaction which can enhance SLA include feedback from NSs which makes NNs aware that their usage is not acceptable in some way, and which provides a model for “correctness”. While children rarely receive such negative evidence。
二语习得的相关概念和理论
母语习得理论（Theories of Acquisition of the Maternal Language）关于儿童对母语，主要是口语中的听和说的能力之获得的理论，主要有：行为主义理论，“先天伦”和认知理论等。
行为主义理论（behaviourist theory)的基础是“强化”论或刺激--反应论，代表人物有语言学家布龙菲尔德和心理学家斯金纳等人。
这种理论认为：语言是一种人类行为，要观察语言行为就必须找出话语和产生它的环境之间的规律，找出话语和对它做出反应的话语之间的规律性，以便建立起一套完整的母语习得理论。
斯金纳在他的代表作《语言行为》一书中认为语言不是一种思维现象，而是一种行为。
儿童母语习得要经过模仿--强化--成形三个阶段。
儿童首先模仿自己周围的语言，对环境或成人的话语做出反应。
如果反应是正确的，即说出的句子符合语法规律，成人就会给予赞扬或以其他方式进行鼓励，以便强化儿童的语言，增加儿童说话的正确性。
为了得到更多的赞扬和鼓励，儿童会重复说过的话，逐步养成习惯，并把它巩固下来。
这样，儿童言语行为的形成过程是一个缓慢的过程，直到其习惯与成年人的说话方式相吻合。
行为主义理论并不能全面正确地反映出儿童母语习得的过程和心理特点。
行为主义者所理解的语言无非是声音的刺激和反应，而且把语言和思维（思想）等同起来。
布龙菲尔德的公式S（实际刺激）—r（言语反应）……s（言语刺激）R（实际反应）就表明了这一点。
行为主义语言观是在一定的历史条件下产生的，它反映了母语习得阶段的阶段性成果，反映了当时人们的认识水平。
它解释了一些母语习得的现象，特别是“语言时习惯”这一观点是不容易被否定的。
语言学习的“天性论”（innateness theory）用典型的理性主义的方法来解释儿童语言习得的问题。
代表人物是乔姆斯基和马克奈尔（D. McNeil）。
这种理论认为：儿童生下来就有一种适于学习语言的、人类独有的能力，即儿童天赋的普遍语法（universal grammar，简称UG)知识。

• Phonetic discrimination studies
– Can hear subtle phonetic differences very early – Lose the ability to hear differences that are not phonemic – Babies in bilingual environments retain the discrimination ability longer
• There is usually no way of tracing back the association of ideas that has caused such misidentifications.
Mean length of utterance: MLU
• Index of grammatical development • Once child begins to combine words, „mean length of utterance‟ is a better indication of development than age. • Calculated by dividing the total number of morphemes by the number of utterances
Vocabulary development: mismatch
• There is no apparent basis for the wrong use of a word by the child.

第二语言习得概论ellis全文翻译
第二语言习得概论Rod Ellis 全书汉语翻译引言写这本书的目的是为了全面的解释第二语言习得，我们尽可能的描述理论，而不是提出理论，所以，本书不会有意识地凸显任何一种二语习得的方法或理论作为已经被认可的看法。
其实，现在做到这一点是不可能的，因为二语习得研究还处于初期阶段，仍有许多问题需要解决，当然，我们不可能完全把描述和解说隔裂开来，所以，对于我所选择描述的理论解释时，不可避免地带有我自己的观点倾向。
这本书写给两类读者，一类是二语习得课程的初学者，他们想整体了解二语研究的现状。
二是想明白学习者怎么学习第二语言的教师。
因为是二语习得的初级教程，第一章列出了有关第二语言习得的主要理论观点。
接下来的几章各自阐述一方面的理论观点，然后第10章汇总所有理论以对二语习得的不同理论进行全面研究。
每章后面提供可进一步阅读的参考建议，这可以指引学生进入二语研究快速发展的前沿领域。
但是，应该想到许多读者是第二语言或外语老师，所以本书也应该让他们对课内和课外的二语习得是怎么发生的有一个清楚的认识。
按传统，是教师决定课堂上学生学习什么和按什么顺序学习。
例如，语言教科书就把既定的内容顺序强加给学生学习，这些课本设想书中设计的语言特征出现的顺序和学生能够接受并习得的顺序相同。
同样，教师在制定教学计划时也会这样做，他们认为精选学习内容和把教学内容排序将有利于教学。
但是除非我们确定教师教学计划和学生的习得顺序相符，不然我们不能确定教学内容可以直接有利于学生学习。
教师不仅决定教学的内容和结构，他们也决定第二语言怎么教，他们决定教学法，他们决定是否操练，操练多少，是否纠错和什么时间纠错以及纠到什么程度，教师们根据他们所选择的教学法来处理语言学习过程。
但是，又一次，我们不能确保教师选择的教学法规则和学习者学习语言的进程是相符的，例如，教师可能决定关注语法的正确性，而学习者可能只关注自己的意思是否被理解，不在乎语法是否正确，教师可能关注操练灌输一个一个语言点，而学生却可能整体上把握语言问题，逐渐的掌握在某一相同的时间处理各种语言点的能力，学生所进行的学习可能不是教师的教学法所设想的。
