Second-language acquisition is also the scientific discipline devoted to studying that process. Since not all of the learners can be at the same level of linguistic competence at the same time, Krashen suggests that natural communicative input is the key to designing a syllabus, ensuring in this way that each learner will receive some 'i + 1' input that is appropriate for his/her current stage of linguistic competence. Acquisition requires meaningful interaction in the target language - natural communication - in which speakers are concerned not with the form of their utterances but with the messages they are conveying and understanding. The order that the learners follow has four steps: 1. The main purpose of theories of second-language acquisition is to shed light on how people who already know one language learn a second language. 1.1.3 the way people view themselves. This is a subtle point. The following are the main ideas to take away from his theories: 1. Finally, the less important Natural Order hypothesis is based on research findings (Dulay & Burt, 1974; Fathman, 1975; Makino, 1980 cited in Krashen, 1987) which suggested that the acquisition of grammatical structures follows a 'natural order' which is predictable. A … They produce single words. Skinner argued that children learn language based on behaviorist reinforcement principles by associating words with meanings. Ideally, speakers strike a balance and monitor at a level where they use their knowledge but are not overly inhibited by it. According to second language acquisition theory, the role of grammar in language acquisition is useful only when the learner is interested in learning grammar. In its most basic form, the input hypothesis argues that learners progress along the natural order only when they encounter second language input that is one step beyond where they are in the natural order. Since 1980, he has published well over 100 books and articles and has been invited to deliver over 300 lectures at universities throughout the United States and Canada. Any subject matter that held their interest would do just as well. This hypothesis argues that there is a natural order to the way second language learners acquire their target language. Page 1 Page 2 The nature vs. nurture debate extends to the topic of language acquisition. As a second language teacher, the ideal is to create a situation wherein language is used in order to fulfill authentic purposes. Research suggests that this natural order seems to transcendage, the learner's native language, the target language, and the conditions under which the second language is being learned. He believed that there are marked differences between social interaction and academic teaching as a method for acquiring and comprehending a second language. According to Krashen, the study of the structure of the language can have general educational advantages and values that high schools and colleges may want to include in their language programs. He's also the cofounder of the Natural Approach, as well as the creator of sheltered subject matter teaching. Krashen also suggests that there is individual variation among language learners with regard to 'monitor' use. Stephen Krashen is an Emeritus Professor of Education at the University of Southern California known for his theory of second language acquisition. CHAPTER10> THEORIES OF SECOND LANGUAGE ACQUISITION What is SLA? 1.1.5 linguistic contrast. Today, most researchers acknowledge that both nature and nurture play a role in language acquisition. When a child who incessantly babbles happens to utter a meaningful word, such as ‘mama’, he is immediately rewarded with squeals of delight, applause and even a tight hug. We continue our examination of some of the more groundbreaking and essential theories on the subject of second language acquisition with the work of James Cummins. SLA is a subject if general human learning, involves cognitive variations, is closely related to one’s personality type, is interwoven with second culture learning, and involves interference, the creation of new linguistic systems, and the learning of discourse and communicative functions of language. The "learned system" or "learning" is the product of formal instruction and it comprises a conscious process which results in conscious knowledge 'about' the language, for example knowledge of grammar rules. Students who are motivated, confident, and relaxed about learning the target language have much more success acquiring a second language than those who are trying to learn with the affective filter in place. The Input hypothesis is only concerned with 'acquisition', not 'learning'. Acquiring a language is largely subconscious because it stems from natural and informal conversations. They string words together based on meaning and not syntax. Second language acquisition theory seeks to quantify how and by what processes individuals acquire a second language. This theory was based on the work of Jerome Bruner about social learning, and claims that language is acquired as the result of interactions that help the infant develop language. Krashen has concluded that there are two systems of language acquisition that are independent but related: the acquired system and the learned system. These factors include motivation, self-confidence, and anxiety. Usually extroverts are under-users, while introverts and perfectionists are over-users. Krashen claims that learners with high motivation, self-confidence, a good self-image, a low level of anxiety and extroversion are better equipped for success in second language acquisition. The second language learner has sufficient time at their disposal. This hypothesis argues that there is a natural order to the way second language learners acquire their target language. The implication is that knowledge of UG must be available to second language learners as well as to first language learners. In summary, the most important contributions to second language learning theory include: Noam Chomsky’s Universal Grammar – Language acquisition is innate and follows a … According to Krashen, the role of the monitor is minor, being used only to correct deviations from "normal" speech and to give speech a more 'polished' appearance. Stephen Krashen An innatist theory of second language acquisition which has had a very great influence on second language teaching practice is the one proposed by Krashen. Krashen's theory of second language acquisition consists of five main hypotheses: The Acquisition-Learning distinction is the most fundamental of the five hypotheses in Krashen's theory and the most widely known among linguists and language teachers.
