Theory Of Second Vocabulary Acquisition English Terms Essay

Second Vocabulary Acquisition (SLA) is a crucial issue to both teachers and learners of another language equally. Thus, teaching and learning another language has always been of an extremely important subject for linguistics who always seek terminology learning solutions to facilitate teachers' job and answer educational enquires. Fillmore and Snow, 2002 and Hamayan, 1990 explained that professors can play an optimistic role in bettering second vocabulary acquisition if they realized how to increase the learners' capability of bulk. This paper will be devoted to Stephen Krashen's second dialect learning acquisition theory. It'll go through the stages of the idea and some relevant approaches for L2 educators and discovers.

Key words: mother tongue, second language acquisition, learning, L2, theory


Linguist Stephen Krashen (1981, 1982), University or college of Southern California, USA has developed the most famous second words acquisition theory (SLA) which is also called the Krashen's Monitor Model. Krahsen has developed his theory of second words acquirers who are assumed to obtain two autonomous systems for improving their potential in acquiring another language and alert to the dialect learning. So, these systems are interconnected within an explicit way where unconscious acquisition appears to be more vital as it takes place naturally. The idea rotates around hypotheses that young learners subconsciously pick up the target vocabulary similarly to acquiring their mother tongue in informal situations. Actually, this is completely not the same as formal learning where it is thought to be dominated by error alteration and the looks of the grammatical rules (Krashen and Seliger, 1975). On this paper, light will be shed on SLA theory, it's components and how important for the L2 professors to be familiarizes with it.

Acquisition and learning

Both the mother tongue and the next language acquisition share different facets. They both require a meaningful interaction, real communication where speakers are paying the most attention for conveying and understand the message as opposed to the form with their utterances. Mistake alteration is more likely not important and coaching grammar is not relevant to acquiring a second language. Coaching should give acquisition an adequate chance to flourish and make the next language learner gains a self-confidence which will help him later on to realize his mistakes and defeat them as this technique will help the acquisition process. (Brown and Hanlon, 1970; Brown, Cazden, and Bellugi, 1973).

On the other hand, formal language learning is thought to be overwhelmed by a great deal of error modification and the life of explicit grammatical guidelines (Krashen and Seliger, 1975). Although problem alteration is sustained, it helps the acquirer comes to the right psychological image of the linguistic simplification. It is stated that, error correction hinders the vocabulary development with a sense of continues stress and anxiety governed by problem phobia. Whether such reviews has this effect on the acquirer to a substantial degree or not remains an open up question (Fanselow, 1977; Long, 1977).

2. The natural order hypothesis

This hypothesis in second terminology acquisition assumes that mastering second terminology grammatical rules took place in a predictable order. Whatever the mom tongue of the learners, acquiring the prospective language rules varies in conditions with their sequential which means that some rules are acquired sooner than others. Yet, second terms grammar should not be trained as it is meant to be bought in this natural order.

3. The monitor hypothesis

This hypothesis claims that acquiring an L2 will be developed automatically allowing the acquirer to screen his new dialect grammatical guidelines and edit the mistakes unconsciously at some stage, which we will see later as "the Monitor".

These keep an eye on uses change from a learner to some other, with different degree of achievement. Stephen Krashen (1981) classify the screens into two types, Over-users who habitually make an effort to use their Monitor, in fact, this application brings about a result of a correct vocabulary lacks a great deal of natural fluency which should help the learners in their real live. Screen Under-users either havent intentionally discovered or decide to not use their aware information of the vocabulary. Even though the changes of errors by others has little influence on the learners, they can frequently correct themselves, down the road, based on a good view for correctness.

4. The suggestions hypothesis

Krashen's theory of SLA is also known as the "source hypothesis", which right answers the question of how a target terms acquirer evolves competency as time passes. It states a language learner who's at "i level" must receive sufficient and rational input that is at his level "i" and a fresh "+1". The new "+1" varies from a learner to a another where an "x" can pick different things form a "z " depending on his backdrop, interest, main concern, attention and the way it is shown.

5. The affective filter hypothesis

Filtering the learner's input varies from a level to some other, so a learner of a second language may not need to filter every single type at the first stage. The role of filtering the new type increases as the learner have sufficient thorough source. At later stage, when the second language learner masters a great deal of L2 rules and have come to the advanced terms effectiveness, filtering becomes subconscious process. This process will form the new terminology and internalize its guidelines forming a local like competency.

The preceding five hypotheses of acquiring L2 can be summed as follow:

1. Acquiring a terms is far more significant than learning. 2. For acquiring a new terms, two conditions are essential, "i+1" input, which should be formed marginally above the learner's present stage, and the next, a minimal sense of filtering to permit the input occurs.

Development of second terms acquisition

Stephen Krashen's concept of second words acquisition "intake' means delivering a language framework a "little beyond" the learner's current competence in the L2 ( Krashen, 1981, p. 103). He sometimes refers to it once we observed an i+1, meaning that the learning situations should concern the L2 acquirer by showing a new input and above the learner's level so that he will acquire something new and develop on what he already has. The concept of the continuum of learning, is said to be a shared occurrence by most current words theorists, where predictable and sequential stages of second dialect development occurs. A child can acquire a second language using almost the same techniques he is applicable in acquiring his mother tongue. In fact, it requires real situational connection in the next language and significant communication where the two get-togethers are nurturing not with the composition of their vocabulary but with the communication they can be passing on and understanding. Problem alteration and pure rules teaching is not highly relevant to language achievements as Dark brown and Hanlon, 1970; Brown, Cazden, and Bellugi, 1973 said. The second language learner advances from no understanding of the new L2 to a level of competency tightly like a indigenous speaker. These ideas however, have discovered different periods for the development of second vocabulary acquisition where they are really determined in five stages:

Stage 1, the receptive or preproduction stage

This stage is also known as the silent stage where the learners develop success vocabulary, pursuing different coaching and learning situations including participating in, miming, simple game titles and listening to stories. This stage could last from hours to half a year. As the learner feels comfortable, he/she begins understanding and interacting with the teacher, his classmates and the encompassing environment utilizing a variety of techniques like directing to surrounding things, standing up, closing the door, nodding or might responding using simple words like "yes" or "no". Professors are recommended never to drive learners to speak at this time.

Stage 2, the early production stage

After acquiring about 5000 words in the first level, the learner provides 1000 lively words, in another six months, allowing his/ her to speak one or two words phrase, and shows understanding by responding to yes/no, some WH questions or even to either or. New vocabularies are required to be presented side by side with revising the old ones. Faults should be tolerated in speaking provided the message is understandable.

Stage 3, the speech emerging stage

The most prominent phenomenal of this stage is the creation of L2 phrases and simple phrases. Through the second 12 months, the learners begins interacting using the next vocabulary in reading and writing for operational purposes. The surrounding should play a good role in motivating the L2 learner and disregarding mistakes as long as the concept is understandable and clear.

Stage 4, the intermediate fluency

At this level the L2 learner is more aware of the usages of academic words in different situations comprehending about 6000 energetic words. He/she can interacts outside the teaching and learning contexts without needing L1 for interpretation thus, he still makes mistakes in complex sentence structure and the usages of new vocabulary. The learner can interacts in educational presentations using visual and hands-on knowledge activities, solve mathematics problems, making models, maps, participate in academic discourse, make brief dental presentations and answer more impressive range order pondering questions.

Stage 5, the advanced language proficiency speakers

This level can be perfected after from five to seven years. The learner can comprehended academic presentations without using aesthetic illustrations. He can use higher reading comprehension skill, writing understanding, accounts and research documents. The learner may use L2 grammar and vocabulary much like his age native learners.

Understanding the learner's level helps the instructor to tailor the materials accordingly and build on the existing talents and remedial the weaknesses.

Mother Tongue and Second Language Acquisition

Mother tongue disturbance has been of a high priority in the history of second dialect acquisition studies and practices. For a long period, it had been reputed that the primary way to obtain syntactic errors in men and women' L2 performance was their mom tongue (Lado, 1957), in addition to a huge deal of resources planning was finished with this assumption at heart (Banathy, Trager, and Waddle, 1966). As a result, experimental studies of errors made by second vocabulary learners guided to the diagnosis, however, that lots of errors are not specific to the guidelines of the mom tongue, but are familiar to second terminology users of different linguistic backgrounds (e. g. Richards, 1971; Buteau, 1970). These results have led several researchers to examine the value of contrastive research and to argue alternatively for error assessment. As clearly explained earlier, the mother tongue is one of lots of causes of error but other factors need to be measured.

A research conducted by Selinker, Swain, and Dumas, 1975; Plann and Ramirez, 1976 discovered that, mother tongue affect appears to be higher in sophisticated phrase order and in term for- term translations of phrases. Mom tongue influence is commonly weaker in bound morphology. Mother tongue impact also appears to be most powerful in "acquisition poor" surroundings. And finally mom tongue influence mistakes here are also in the area of word order.

Pedagogies Providing Krashen's Theory

The question which most of us need to ask ourselves is, " How can a second terminology learner benefits from a formal learning situations?"

Formal learning or face-to-face learning can be of a great advantage for an L2 learner if it offers a comprehensive suggestions. In the event the learner current ability helps him to add something more to his "i" or as Vygotsky called ZOPD.

It is also said that class or formal learning cannot supply the acquirer with the extensive range of daily issues and sociable langue needed. So the classroom's role is to prepare the learners for dealing with true to life situations by delivering an adequate daily actual dialect contexts.

The theory also advised that learners who are not able to speak "output" for physical problems can still learn the full ability to comprehended words by showing comprehensible input reliance on each learner. Teachers need to be slower and carefully articulate using common vocabulary and avoid dilates, slang terms and shorter sentences.

Teachers should assist in presenting the perfect monitor users concerning promote communication and avoid hindering acquisition with grammatical guidelines domination.

In addition to getting the appropriate input, acquirers need to have their emotional filtration system kept minimum which can only help them get the utmost input from the encompassing and allow them to understand the techniques of dialogue and ideas exchange.


Acquiring and learning another language is vital in a bilingual and multi lingual culture. It is also a necessity in the current global world where technology is mostly limited to specific countries speaking a tiny number of dialects. Actually, a lot of students, educators, specialist and politics find themselves in an awful dependence on learning these languages.

As presented preceding, Krashen's theory of second terminology acquisition, suggested some useful approaches for teaching and acquiring a second language. Professors are urged to utilize such theories for facilitating their job and supporting their students acquire and find out better.

Although this theory was a result of studies conducted in America on bilingual and multilingual speakers, our students in the Arab world generally speaking and in the UAE specifically could gain the almost all of it with the aid of their teachers. The concentrate should be how to slowly but surely help the learners pick the foreign language in a manner that give attention to fluency alternatively than precision.
