Learning contains a number of characteristic features (Brown, 1994):
1) Learning is acquisition or "getting". 2) Learning is retention of knowledge, information or skill. 3) Retention implies storage systems, memory, and cognitive organization. 4) Learning involves active, conscious focus on and acting upon events outside or inside the
Pre-learning Tasks
1. Search the internet to get the definitions of language and learning and explain them with examples to your classmates. 2. Reflect on your own experience of learning the mother tongue. 3. How do you understand the act of learning? Is language learning similar to other types of learning? Why ?

Acquisition and Learning
• The distinction between acquisition and learning is formally made by S.Krashen.
• According to Krashen, acquisition refers to subconscious learning in the natural environment that is not influenced by explicit instruction in a second language's rules and system or about errors(1985)
• basic similarity: non-native language • basic distinction:
education,goverment or business(ESL)
geographical context little exposure to native use of the language or few opportunities(EFL)
Competence and Performance
• It is a distinction introduced by Chomsky into linguistic theory but of wider application.

In the classroom, we can provide an hour a day of comprehensible input, which is probably much better than the outside can do for the beginner.
Context Clue 3: General knowledge
More often than not, the meaning of many words can be readily guessed if you use your own experience or general knowledge of the subject.
Context Clue 6: Comparison
When we compare things, we see how they are like each other. So comparisons in writing can give you clues to the meanings of unfamiliar words.

Examples of foreign language learning are English learnt in China，France or Japan.Second Language AcquisitionIn the broad sense, “second”can refer to any language that is learned subsequent to the mother tongue. Thus, it can refer to the learning of a 3rd or 4th language. Also, “second” is not intended to contrast with “foreign”.Whether you are learning a language naturally as a result of living in a country where it is spoken (naturalistic or spontaneous), or learning it in a classroom through instruction(instructed or guided), it is customary to speak generically of “second” language acquisition. ?L2 acquisition can be defined as the way in which people learn a language other than their mother tongue, inside or outside of a cla ssroom, & “Second Language Acquisition” (SLA) as the study of this.S L ASLA took place around the end of the 1960s, developed in the 1970s or even early 1980s. ?SLA is a complex, multifaceted（多方面的）phenomenon & it’s not surprising that it has come to mean different things to different people.Competence v. performanceAccording to Chomsky (1965) Competence consists of the mental representations of linguistic rules that constitute the speaker-hearer’s internal grammar.Performance consists of the use of this grammar in the comprehension & production oflanguage.Communicative C o m p e t e n c e v.p e r f o r m a n c e ?Communicative Competence includes both linguistic & pragmatic knowledge (knowledge the speaker-hearer has of what constitutes appropriate as well as correct language behavior & also of what constitutes effective language behavior in relation to particular communicative goal.Communicative performance ?Communicative performance consists of the actual use of these two types of knowledge in understanding & producing discourse.Usage v. UseAccording to Widdowson (1978):Usage is “that aspect of performance which makes evident the extent to which the language user demonstrates his knowledge of linguistic rules ”.We study usage if we focus attention on the extent to which the learner has mastered the formal properties of the phonological, lexical, & grammatical systems.Usage v. UseUse is that aspect of performance which “makes evident the extent to which the language user demonstrates his ability to use his knowledge of linguistic rules for effectivecommunication”.We study use if we examine how learners convey meaning through the process of constructing discourse.Usage v. Use由威德森提出的一种区分方法，一个语言项目如作为语言系统中的一个成分，其功能成为语言系统中的用法（usage），如果是作为交际系统中的一部分，则其功能成为具体用法（use）。

•互动假设
• 作为克拉申语言输入假设的扩展，Michael Long （1981）提出“互动假设”。
• 他认为，单向的语言输入对理解和认识语言输入 的本质及其对SLA发展的影响来说远远不够，需 要高度关注母语者和学习者共同参与的互动过程 。
• 在进行意义沟通时，母语者为学习者提供的语言 输入在语言形式和话语结构和功能上作出了调整 。前者的调整使语言输入符合学习者的语言水平 ；后者的调整通过询问、重复、确认、解释等方 式使语言输入更容易理解。
34
• Michael Long(1983:126)发现
• 语言形式的调整对为第二语言学习者提供可理解 输入远远不够，母语者在互动时，对“话语结构 ”（interactional structure of conversation） 的调整最多，对提供可理解输入更为重要。
• Michael Long 刻意区分两个概念：“语言输入 调整”（modified input）与“互动调整”（ modified interaction）。
• 另一方面，外在的语言输入为学习者提供的仅仅 是关于目的语结构规则的“正面证据”（ positive evidence），缺少“反面证据”（ negative evidence）。
• 结果： 知道“怎样说”，不知道那些规则“不能 说”。

对“儿向语言”的研究
• 有学者发现：儿童的父母或保姆为儿童提供的都是符合规 则的话语，几乎很少纠正儿童的语法错误，为儿童提供不 合规则的反面证据。

二、互动研究的心理语言学视角
• 学习者们试图从心理语言学的角度来进一步探讨语言习得 环境对语言习得的影响。学者们关注最多的是语言“反馈 ”（feedback）在母语者与第二语言学习者的互动过程 过外在的输入习得的 。

4. 学习者语言偏误的解释
• 对学习者偏误的解释需要对偏误的来源进 行分析，通过分析来建立与第二语言习得 相关的过程。
• 因而，对学习者偏误产生的来源的分析， 是基于偏误产生的过程的分析。
• 通过过程的分析对作为产出结果的偏误进 行解释。基于过程的偏误分析和解释才有 意义。
5. 学习者语言偏误的评价
• 对比分析的两种版本：
• 强势版本：用对照分析方式来预测困难等 级的方法。
• 弱势版本：使用对照分析法来解释可以观 察的到困难。Oller和Ziahosseiny提出细微 差异(subtle differences)版的对照分析假说 理论：“不管在单一或多种语言系统间， 即使他们的差异极为渺小，终究还是会产 生困惑。”

Performance consists of the use of this grammar in the comprehension and production of language.
Communicative competence includes knowledge the speakerhearer has of what is effective as well as correct language behavior and also of what constitutes effective language behavior in relation to particular communicative goals. It includes both linguistic and pragmatic knowledge.
Communicative performance
Consists of the actual use of these two types of knowledge in understanding and producing discourse
The main goal of SLA research is to characterize learners’ underlying knowledge of the L2, to describe and explain their competence. However, learner’s mental knowledge is not open to direct inspection. It can only be inferred by examining samples of their performance.
Usage demonstrates the learner’s knowledge of linguistic rules; use demonstrates the learner’s ability to use his knowledge of linguistic rules for effective communication.

An Introduction to SLA
What is second language acquisition?
A. second VS third language acquisition Many learners are multilingual in the sense that in addition to their first language, they have acquired some competence in more than one non-primary language. However, the “term” second is generally used to refer to any language other than the first language. Any language additional to the native language is called second language.
Different kinds of performance
Usage VS. use The distinction was first proposed by Widdowson(1978). Usage is that aspect of performance which makes evident the extent to which the language user demonstrates his knowledge of linguistic rules We study usage If we focus attention on the extent to which the learner has mastered the formal properties of phonological, lexical, and grammatical systems
Why we study SLA
1. The study itself is fascinating in its own right. Understanding it requires drawing upon knowledge of psychology, linguistics, sociology anthropology, psycholinguistics, sociolinguistics and neurolinguistics.
It is wrong to assume that naturalistic is subconscious and instructed is conscious. SLA deals with both of them The distinction is used in its sociolinguistic sense.
The distinction between the settings may be significant. It is possible that there will be radical differences in both what is leant and how it is learnt. Learning outcome and learning process will be different. How different they will be? SLA is used to cover both types of learning.
Use is that aspect of the performance which makes evident the extent to which the language user demonstrates his ability to use his knowledge of linguistic rules for effective communication. E.g. how learners learn to perform speech acts like request and apologizing. Pragmatic aspects
e. Acquisition VS. learning
Some researchers (Krashen 1981) distinguish between acquisition and learning. Acquisition refers to the subconscious process of picking up a language through exposure. Learning refers to the conscious process of studying it. SLA includes both of them.
B. Second vs. foreign language
In second language acquisition, the language plays an institutional and social role in the community; it functions as a recognized means of communication among members who speak some other language as their mother tongue. E.g. English is learnt in US as a second language. In contrast, foreign language learning takes place in settings where the language plays no major role in the community and is primarily learnt only in the classIt can take place in a naturalistic or an instructed way. The goal of SLA is the description and explanation of the learners’ competence. To this end, the researchers must examine aspects of the learner’s usage of the L2 in actual performance, by collecting and analyzing samples of learner language
d. Competence VS. performance
According to Chomsky(1965), competence consists of the mental representations of linguistic rules that constitute the speaker-hearer’s internal grammar. It is implicit and evident in the intuitions which the speaker-hearer has about the grammaticality of the sentence.
SLA research has been primarily concerned with studying usage, although it is now paying more attention to use. It has become apparent that even if the aim is to find out how learners acquire formal features, it is often necessary to examine how they use these features to express meaning.
