...skills that they will use throughout the education. Also, both of the lesson plan and modifications use prior knowledge (ELL’s) to help them make connections with things they may know in their native language with things they need to learn and know in English (Ford, 2010). The lesson plan and the modifications incorporate different theories; one previously mentioned is lowering the affective filter. The lesson plan and modification have students working together and socializing; which according to Stephen Krashen is a great way to minimize the stress level within the classroom and it gives ELLs the opportunity to practice the language without having to worry about being reprimanded or being looked down upon. Stephen Krashen also believes that for an ELL to acquire a second language they need to have plenty of opportunities to use and practice the language; “Not with the form of their utterances but with the messages they are conveying and understanding” (Krashen, 1981, pg.1, para.2). The modifications made to this lesson plan provide English language learners the opportunity to connect their culture and language with the language they are learning; which comes from giving students the opportunity to relate with things they know with what they are learning through a new language. Also, none of these modifications require students to completely forget about their culture or their native language, because they are using it learn new things and from this these......

Learning vs. Acquisition

...The Input Hypothesis: Krashen views the whole process of language learning through five integral hypotheses, which we can find very interesting if we did not account for the big leaks that each of those hypotheses has while reading them. It makes a lot of sense to differentiate between learning and acquisition, as Krashen does, claiming that acquisition happens subconsciously and we produce language by the knowledge we gain; whereas learning is a conscious process entailing realizing “rules” and being able to talk about them. This differentiation reminds us of the two major types of cognitive knowledge: Procedural Knowledge and Declarative Knowledge, to which Krashen never connects his hypothesis, claiming that acquisition is guided by Universal Grammar through the Language Acquisition Device and that learning can never be turned into acquisition in a formal setting. He also thinks that the learned knowledge acts as a filter or a monitor on the acquired knowledge which is responsible for production, but he does not account for this monitor in comprehension in both L1 and L2 settings. Supporting these claims, Krashen studied the order of morpheme acquisition to assume that language is acquired in a predictable order controlled by the Universal Grammar, but he ended up noticing differences and variations in the order. The last two hypotheses of Krashen, which mainly account for second language learning, are the Input and the Affective Filter Hypotheses. People acquire second......

How Are Krashen and Vygotsky Similar in Their Perceptions on Sla.

...When revisiting Krashen and Vygotsky , their philosophical view of language is viewed as a tool that is best used when the individual feels that it is important, natural, and relevant to them in Vygotsky’s view, the collaborative interaction of learners as part of a social system within the classroom takes place between students who are MKOs (More Knowledgeable than Others), and their peers. The cooperative learning with MKOs helps empower their peers to absorb new information, and to allow learning to take place as a process. Vygotsky theorizes that this process occurs within a student’s ZPD (Zone of Proximal Development) and that the goal of the relationship between the MKOs and their peers is to extend the peers’ ZPD by increasing the knowledge, and expanding their learning potential (Vygotsky, 1978). Concisely, both Bandura and Vygotsky concide in that the learner’s role within a society that invites the acquisition of new behaviors and skills is the underlying motivator that enables the learning to occur. This is how, whether cognitively, intra or inter psychologically, socially, or behaviorally, these theorists embody the promotion of social change through the theoretical notions of learning and acquisition that are promoted in their philosophical benchmarks. Krashen’s theory of second language acquisition is one that combines social learning and cognitive development. It agrees with Bandura in that language is a process that is learned through observation and......

...interactions between parents and children often took the form of speech from the parent followed by a physical response from the child. Asher made three hypotheses based on his observations: first, that language is learned primarily by listening; second, that language learning must engage the right hemisphere of the brain; and third, that learning language should not involve any stress. Total physical response is often used alongside other methods and techniques. It is popular with beginners and with young learners, although it can be used with students of all levels and all age groups. Natural approach From Wikipedia, the free encyclopedia Jump to: navigation, search 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. The natural approach has become closely associated with Krashen's monitor model, and it is often seen as an application of the theory to language teaching. Despite this perception, there are some......

...“place their pencils on their desk” and then asking them to “place the pencils inside their books”, made a slight change but builds on the prior knowledge of placing the pencil someplace. This deals mainly with both input and the ouput part of the comprehension. Instructional implications of these strategies that may be faced may be that of the learner’s setbacks affecting the progression of learning the 2nd language. Setbacks may include the time given or time put into to learning a particular idea/concept for the language and being able to obtain the appropriate information within a given time frame, in other words they may not feel rushed when learning a concept. Krashen stated "We acquire, in other words, only when we understand language that contains structure that is 'a little beyond' where we are now." (Krashen,1981) As I stated in the portion of this journal about going a little beyond each time when giving instruction, I believe this may present a problem; especially knowing that students sometimes do not immediately grasps concepts and ideas. The students cannot stay on one idea or concept forever and the only time to cover concepts or teach a language, or at least the parts where confusion arises, is during the re-teaching portion allotted during the school year. At the re-teaching point, then the portion of the concept can be re-taught, possibly in a better form with a different approach....

Bilingual Educatio

...Bilingual language is beneficial for the child’s first language and English development “Language constitutes us, it gives us meaning and allows us to make meaning, and it develops and abolishes spaces.” (Benjamin, 2002). Critiques of bilingual education continually claim that children can only learn one language at a time after which they are taught a second language (Krashen, 2000). They assert that bilingual education cause confusion among children and limit their intelligence capabilities; they argue that real bilinguals cannot combine their language. Advocates of bilingual education present arguments on its benefits, they suggest that, for many children the process of being literate and studying a new language simultaneously is overwhelming and that the bilingual process assist them to develop their native language first which results to a smooth transition to English. The main aim of the bilingual program was to promote the prominent language to issue instructions and at the same time enhance the development of the second language. Some define it in aspects of its capability to enhance cognitive and effective development while others view that it should focus on cultural enrichment and linguistic development. However, in some bilingual programs, instructions are issued through the use of the second language especially in cases where the first language erodes over time. (Baez, 2002) As the child proficiency in English increases he or she loses grasp of the native......

Is Call Obsolete

...I decided to read, Is CALL Obsolete? Language Acquisition and Language Learning Revisited in a Digital Age by Huw Jarvis and Stephen Krashen. Computer-Assisted Language Learning or CALL for short has become an ever expanding. CALL was created to help people learn different languages with the use of computers. It came about in the 1960's before much was known about how we learn different languages. I think this seemed like a good idea at the time, but the creator just did not have enough data on how humans learn new languages. Now fifty years later different methods and practices of it have helped more people to better understand languages that are new to them. When CALL was first created it used a method that like I said seemed a good idea, but did not help people grasp languages that were new to them. The method that was used was more of a read and repeat method. We now know that while this method may have aided in language learning, it did not contribute to language acquisition. The Merriam Webster dictionary defines acquisition as "the act of getting or acquiring something: such as the act or process of gaining skill, knowledge, etc". This means that you can read and repeat all you want, but you are not gaining the skill or full knowledge of this new language. When learning a new language we also need understanding. According to Krashen, 2003, 2001, "we acquire language and develop literacy primarily from understanding what we read and hear, that is , when we obtain......

Research Summary Review

...Review of “Research Summary and Bibliography for Structured English Immersion Programs” of the Arizona English Language Learners Task Force Stephen Krashen University of Southern California Kellie Rolstad Arizona State University Jeff MacSwan Arizona State University The “Research Summary and Bibliography for Structured English Immersion Programs” of the Arizona English Language Learners Task Force purports to present a scholarly and balanced review of current scientific knowledge regarding effective programs for English Language Learners (ELLs) in general and Structured English Immersion (SEI) in particular. However, we find that the review neglects to reference significant research bearing on the questions raised, and frequently draws inappropriate conclusions from the research presented. Perhaps most disappointing is the tendency in the review to neglect important conceptual distinctions which could have usefully guided the research summary. Below we address each area of literature review in turn, pointing out significant limitations and incorrect interpretations as they arise. 1. What is the current state of scientific research in the area of effective instruction for English Learners? The review cites references to make the point that there are relatively few high quality studies regarding program effectiveness for English Language Learners, with estimates ranging from five (Gersten & Baker, 2000) to fifty (Genesee, Lindholm-Leary,......

Language and Science

...well-received universally in the language teaching field (Briton, 1989). It refers to the pedagogics in language teaching based on a certain subject or a certain theme content. It attaches importance on the combination of language study and subject content study. The emphasis of language teaching is no longer the language itself. Instead, it is the acquirement of the targeted language competence through learning the subject knowledge. The CBI focuses on the collaboration of language system and content. It teaches in the targeted language. The communicative approach, which is dominate in current teaching of foreign language, has ignored the subject content of the communication either in terms of theory or in terms of teaching principles (Krashen, 1982). The CBI is put forward on the basis of the recognition of the problem. Thus it forsakes the traditional pedagogics of isolating the teaching the language of science to second language speakers. It embodies the overall teaching ideology, applying the training of skills such as listening, speaking, reading, and writing ti the practice of the language. It is conducive to broadening students’ knowledge, cultivating students’ critical thinking ability, and enhancing students’ innovation capacity. 2. The theory basis of CBI The birth of content-based instruction owes to the communicative approach. The sociolinguist D.H.Hymes first put forward the far-reaching concept of communicative competence in 1972 in his book On......

Influence of Music to Language Learners

...not been learned formally. Of the 3,000 words the average child acquires each year, only a portion is learned as a result of the instruction received in school. Thus, the remainder of these words must be learned incidentally from a variety of sources (Nagy & Herman, 1987). There is substantial evidence that vocabulary may be acquired incidentally by reading or listening to oral stories (Cohen, 1968; Elley, 1989; Eller, Papps, & Brown, 1988). This incidental acquisition of vocabulary is explained by Krashen (1989) within the context and framework of his "Input Hypothesis." According to this hypothesis, new and unfamiliar vocabulary is acquired when its significance is made clear to the learner. Meaning is conveyed by providing extralinguistic support such as illustrations, actions, photos, and realia. This, in turn, results in what Krashen refers to as "comprehensible input" since the linguistic input is made comprehensible to the second language leamer. Krashen further states that the amount of comprehensible input is proportionate to the amount of vocabulary acquired. Thus, vocabulary is incidentally acquired through stories because familiar vocabulary and syntax contained in the stories provide meaning to less familiar vocabulary. Picture illustrations support the reading process by clarifying the meaning of unfamiliar words (Hudson, 1982; Omaggio, 1979; Mueller, 1980; Bradsford & Johnson, 1972). Apart from oral stories, there may be other means of......

...process or evolution of the rule development is called rule formation. With these rules they have created, children will test, revise and adjust the rules until they feel they are not in adequate anymore. The language is learnt through hypothesis-testing. It is the process through which interlanguage takes place. The development of rules is deduced from the language they hear around them such as parents. The learners are constantly testing the hypothesis. When a learner stops learning a language before reaching native-like mastering it is called fossilization. In light of what Chomsky said, Stephen Krashen said that the way that we learn a second language is learnt the same way we learnt our first language. Krashen explained second language learning in terms of Krashen's 'Monitor Model'. In this model there are five hypotheses. In the Acquisition versus Learning Hypothesis, Krashen claims that there are two distinct kinds of language knowledge. First being conscious language knowledge. Conscious language knowledge is developed through learning. Learning is the formal development of language through grammar instruction. The second being unconscious language learning, which is developed through acquisition. This is similar to first language acquisition. Acquisition is the development of language without formed instruction. It does not attend to the grammar rules but rather the content. Acquisition uses the Learning Acquisition Device processing input. Only acquired language is......

Interaction and Speaking Skill

...formal process which is aided by rules and error correction. Krashen (1994) summarizes: “In everyday terms, acquisition is picking up a language. Ordinary equivalents for learning include grammar and rules” (p.52). The Natural Order Hypothesis states that “students acquire (not learn) grammatical structures in a predictable order” (p.52). In other words, some structures are acquired earlier than others. An important component of this hypothesis is that the acquisition order is different for the first language than for the second language. Although individuals differ in their exact order of acquisition there can be said to be an average order and a natural order. Importantly, this does not imply that teachers should teach language in order of acquisition. In fact, Krashen states “…there is good evidence that language teaching aimed at acquisition should not employ a grammatical syllabus” (p.53). The Monitor Hypothesis serves as a modifier of the Acquisition-Learning Hypothesis. It states that acquisition is more important and leads more directly to second language fluency; whereas learning is used to monitor, or edit, second language production. The monitor is not easy to use. In order to use it effectively three conditions are necessary: time, focus on form, and knowing the rule(s). Even when all of these conditions are met there is no guarantee that specific rules of grammar will be met. Krashen notes that “research strongly suggests that conscious......

Methodological Approaches

...This activity is based on the NATURAL APPROACH (Krashen & Terrell, 1983; Terrell et al, 1997) as it is possible to recognize in the reading the elements that are involved in it . These elements are Comprehensible Input, Natural Order, Language Acquisition, Monitor, and the Affective Filter. At the beginning of the article the author mentions that the use of charts and tables is a good way of providing comprehensible input imbedded in a meaningful context. According to Krashen the Input Hypothesis answers the question of how a language acquirer develops competency over time. He states that a language acquirer who is at "level i" must receive comprehensible input that is at "level i+1." "We acquire, in other words, only when we understand language that contains structure that is 'a little beyond' where we are now." This understanding is possible due to using the context of the language we are hearing or reading and our knowledge of the world and this is possible using instructional material based on real information as in the reading. Another interesting idea worth mentioning is the fact that these charts and tables can be used not only with basic level students but also with more advanced supporting the idea that the speech emerges in stages. The article points out that students at the first levels should only answer simple questions with one word. On the other hand advanced students might provide more elaborated answers emphasizing the feature that the input should...

...ESL-223N SEI English Language Teaching: Foundations & Methodologies  Grand Canyon University May 13, 2012 Second Language "Standards for Success": Out of Touch with Language Acquisition Research is an article written by Stephen Krashen. (2005; International Journal of Foreign Language Teaching 1(2): 12-16) This article discus the foreign language learning standards and how they may apply to a school curriculum. The article talks about comprehension and its role when it comes to language. There was some research that determined a lot of others relay to us or what we may read and understand helps with the theory of comprehension hypothesis. This hypothesis can help a student develop their language. If the student is read to and talk to in the language they are attempting to comprehend this will help the student better understand that language. The more the student is exposed to different words and their meanings the better the student chances of learning that new language. A teacher could use the comprehension hypothesis in their personal situations by conducting their classes in the language they would like each student to learn. For example if the students at Ell students the class should be conducted in as much English as possible so that the students can get a better understanding of the language. The teacher should use correct grammar when talking and reading to the students. The article talks about how students can make some improvements to their writing......
