Second Language Acquisition Prepared By: Dr. Emma Alicia Garza Assistant Professor Texas A&M University-Kingsville Second Language Acquisition Presentation Script Slide 1: The topic for this training session is Second Language Acquisition. As teachers of second language learners, we must have a basic working knowledge base regarding the process that language learners go through to learn a second language. This knowledge base will be based on research-grounded theories of second language acquisition. The foundation for many of the pedagogical practices, strategies and methodologies used in bilingual and ESL classrooms are derived from theory. What is Second Language Acquisition? In second language learning, 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 native tongue. In foreign language learning, language plays no major role in the community and is primarily learned in the classroom. The distinction between second and foreign language learning is what is learned and how it is learned. Slide 2: Learning a second language requires: 1. formal language instruction in an academic setting; 2. interactions with the second language outside of the classroom; 3. pedagogical practices, strategies and methodologies which facilitate second language learning (how); and 4. teaching the four language skills: listening, speaking, reading, writing along with comprehension and thinking (what). Slide 3: The study of second language acquisition involves: 1. how second languages are learned ( the process); 2. how learners create a new language system with limited exposure (interactions); 3. language proficiency levels (competence and performance of the language); and 4. why some learners achieve native-like proficiency. How Do Learners Acquire a Second Language? Learners acquire a second language by making use of existing knowledge of the native language, general learning strategies, or universal properties of language to internalize knowledge of the second language. These processes serve as a means by which the learner constructs an interlanguage (a transitional system reflecting the learner’s current L2 knowledge). Communication strategies are employed by the learner to make use of existing knowledge to cope with communication difficulties. Slide 4: Learners acquire a second language by drawing on their background experiences and prior knowledge in their first language. They experiment with the second language by using features found in their first language which are similar to those in the second language. This dependence on the first language serves to help the learner construct an interlanguage, a transitional system consisting of the learner’s current second language knowledge. Communication strategies help the learners use what they already know to overcome breakdowns in communication. Slide 5: Individual differences affect second language acquisition. These differences may be developmental, cognitive, affective or social. There are factors that are fixed which we cannot control such as age and language learning aptitude. There are some variable factors such as motivation which are controlled by social setting and the course taken for developing the second language. Teachers need to know that variable factors are controlled through the learning environment, by knowing their students’ cognitive styles, their learning preferences, how they teach, and what they teach. Slide 6: There are many different types of learner strategies which teachers need to be aware of in order to understand the strategies children bring with them and how they learn best. Language learners may need to be taught strategies for relating new knowledge to prior knowledge, for organizing information more effectively and for seeking opportunities for communicating with target language speakers. Slide 7: Researchers identified a natural order of strategies for developing a second language. The order of development starts with the very simple imitation of a word or language structure, to self-talk, to self-correcting, and to role-playing. An awareness of this natural order can help teachers of second language learners plan lessons to facilitate language learning and increase the learners’ self-esteem and self-confidence. Slide 8: There are several theories of second language acquisition which have provided information on how second languages are learned. The Universalists studied a wide-range of languages to find out how languages vary and what makes them vary. They looked at language patterns, language universals (features of language which are common across many languages) as well as other properties of language. Slide 9: Universalists also claimed that language is acquired through innateness (nature) and that certain conditions trigger the development of language (nurture). The search for meaning is innate. Activities and instructional materials need to be presented in a meaningful, relevant and interesting manner in order to allow students to make language learning connections. Slide 10: Behaviorists claimed that learners learn by undergoing training and practice through a series of stimulus and response chains and operant conditioning. The environment provides the stimulus and the learner provides the response. According to the Behaviorist theory, reinforcement motivates the formation of a language habit. Behaviorist Theory Theory (Continued) When the learner learns a language, this learning includes a set of stimulus- response-reward (S-R-R) chains. Imitation provides the learner with a repertoire of appropriate, productive responses. The learner learns to imitate or approximate the productive responses provided by the environment. The characteristics of human and non-human learners include the ability to: 1. respond to stimuli in a certain way; 2. intuitively evaluate the reward potential of responses; 3. extract the important parameters that made up the stimulus response (positive reward chains); and 4. generalize these parameters to similar situations to form classes of S-R-R chains. Slide 11: Language learning requires effort and practice. Behaviorists further claimed that learners imitate or approximate productive responses. For instance, learning how to write is not universal across cultures because some cultures do not have a history of written language, therefore learning how to write involves a conscious effort and specific training, as well as a willingness to learn by trial and error. Responding to stimuli in this instance is critical in order for writing to take place. Slide 12: Nativists claimed that language learning is biologically determined. Each person is born with an innate ability to learn language. The basic innate language learning capacities are referred to as the Language Acquisition Device (LAD). This view asserts that the environment only serves to trigger the Language Acquisition Device (LAD) which determines what children acquire. Children acquire much of their language ability before coming to school, thus supporting the innate structures argument. Nativist Theory Theory (Continued) McNeill (1966) described the LAD as consisting of four innate linguistic properties: 1. the ability to distinguish speech sounds from other sounds in the environment; 2. the ability to organize linguistic events into various classes that can be refined later; 3. knowledge that only a certain kind of linguistic system is possible and that other kinds are not; and 4. the ability to engage in constant evaluation of the developing linguistic system in order to construct the simplest possible system out of the linguistic data that are encountered. Nativists have contributed to the discoveries of how the system of child language works. Theorists such as Chomsky, McNeill, and others helped us understand that a child’s language, at any given point, is a legitimate system in its own right. Slide 13: The Nativists also contend that learners actively construct grammar for themselves by actively listening to the language around them and trying to determine the patterns in the utterances. Learners progress through language in predictable stages. The learner will not respond to error correction if he/she is not developmentally ready. Slide 14: Cognitivists claimed that the conditions for learning language are the same conditions that are necessary for any kind of learning. They believed that human beings have the capacity for developing logical thinking. Acquiring knowledge is a cognitive process which involves automatic processing (rountinzed) and controlled (temporary) learning. Cognitivist Theory Theory (Continued) Language Learning as a Cognitive Process 1. Learning a language involves internal representations that regulate and guide performance. 2. Automatic processing activates certain nodes in memory when appropriate input is present. Activation is a learned response. 3. Memory is a large collection of nodes. 4. Controlled processing is not a learned response. It is a temporary activation of nodes in a sequence. 5. Skills are learned and routinized only after the earlier use of controlled processes have been used. 6. Learner strategies contain both declarative knowledge i.e. knowing the ‘what’ of the language-internalized rules and memorized chunks of language, and procedural knowledge i.e. know the ‘how’ of the language system to employ strategies. Slide 15: The Cognitive theory underscores the fact that the learner brings an innate mental
