Language is the most important and
the best human ability to communicate what we feel, want and many other types
of expression around the world. The vast majority of humans are born with the
ability of acquire language naturally and improve this ability with the right
environments. The language is a creative expression used in every aspect of our
lives, and has been in constant development since ages. The English language is
one of the most important languages around the world, and one of the more
widespread languages now a day. English is a western Germanic language which
was born in the Anglo-Saxons kingdoms of England, its native speakers are the
equivalent of the 5.52% of the entire global population.
The text English language is
tremendously important for us, as in training English teacher, for this text
tells us about history of the language and its development through the eras. In
relation with the course, lexical Analysis, the text takes an important role because
in order to know how to define this language and how English has grown through
time, we need to learn about its roots. We also need to take into account the
difference between the modern English and the old English, thus we can analyze
it and learn why we use some words or why some words are easy to learn in
comparison to others.
In our humble opinion, we think that
as future teachers are seriously meaningful to know and learn about how this
language was born and developed, because in order to teach the language to our
future possible students, we need to really know what we are talking, and we
need to be able to handle every aspects of the language we are improving.
Stephen Krashen (University of Southern California) is
an expert in the field of linguistics, specializing in theories of language
acquisition and development. Much of his recent research has involved the study
of non-English and bilingual language acquisition. During the past 20 years, 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.
This is a brief description of Krashen's widely known
and well accepted theory of second language acquisition, which has had a large
impact in all areas of second language research and teaching since the 1980s.
Krashen's theory of second language acquisition consists
of five main hypotheses:
- the Acquisition-Learning hypothesis;
- the Monitor hypothesis;
- the Natural Order hypothesis;
- the Input hypothesis;
- and the Affective Filter hypothesis.
1.
The Acquisition-Learning
hypothesis
The Acquisition-Learning
hypothesis distinction is the most fundamental of all the hypotheses
in Krashen's theory and the most widely known among linguists and language
practitioners. According to Krashen there are two independent systems of second
language performance: 'the acquired system' and 'the learned system'. The
'acquired system' or 'acquisition' is the product of a subconscious
process very similar to the process children undergo when they acquire their
first language. It requires meaningful interaction in the target language -
natural communication - in which speakers are concentrated not in the form of
their utterances, but in the communicative act.
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. According to Krashen 'learning' is less important than
'acquisition'
2.
The Monitor hypothesis
The Monitor
hypothesis explains the relationship between acquisition and learning and
defines the influence of the latter on the former. The monitoring function is
the practical result of the learned grammar. According to Krashen, the
acquisition system is the utterance initiator, while the learning system
performs the role of the 'monitor' or the 'editor'. The 'monitor' acts in a
planning, editing and correcting function when three specific conditions are
met: that is, the second language learner has sufficient time at his/her
disposal, he/she focuses on form or thinks about correctness, and he/she knows
the rule.
It appears that the
role of conscious learning is somewhat limited in second language performance.
According to Krashen, the role of the monitor is - or should be - minor, being
used only to correct deviations from "normal" speech and to give
speech a more 'polished' appearance.
Krashen also suggests
that there is individual variation among language learners with regard to
'monitor' use. He distinguishes those learners that use the 'monitor' all the
time (over-users); those learners who have not learned or who prefer not to use
their conscious knowledge (under-users); and those learners that use the
'monitor' appropriately (optimal users). An evaluation of the person's
psychological profile can help to determine to what group they belong. Usually
extroverts are under-users, while introverts and perfectionists are over-users.
Lack of self-confidence is frequently related to the over-use of the
"monitor".
3.
The Natural
Order hypothesis
The 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. For a given
language, some grammatical structures tend to be acquired early while others
late. This order seemed to be independent of the learners' age, L1 background,
conditions of exposure, and although the agreement between individual acquirers
was not always 100% in the studies, there were statistically significant
similarities that reinforced the existence of a Natural Order of language
acquisition. Krashen however points out that the implication of the natural
order hypothesis is not that a language program syllabus should be based on the
order found in the studies. In fact, he rejects grammatical sequencing when the
goal is language acquisition.
4.
The Input hypothesis
The Input hypothesis
is Krashen's attempt to explain how the learner acquires a second language –
how second language acquisition takes place. The Input hypothesis is only
concerned with 'acquisition', not 'learning'. According to this hypothesis, the
learner improves and progresses along the 'natural order' when he/she receives
second language 'input' that is one step beyond his/her current stage of
linguistic competence. For example, if a learner is at a stage 'i', then acquisition
takes place when he/she is exposed to 'Comprehensible Input' that belongs to
level 'i + 1'. 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.
5.
the Affective
Filter hypothesis
the Affective Filter
hypothesis,embodies Krashen's view that a number of 'affective variables' play
a facilitative, but non-causal, role in second language acquisition. These variables
include: motivation, self-confidence and anxiety. Krashen claims that learners
with high motivation, self-confidence, a good self-image, and a low level of
anxiety are better equipped for success in second language acquisition. Low
motivation, low self-esteem, and debilitating anxiety can combine to 'raise'
the affective filter and form a 'mental block' that prevents comprehensible
input from being used for acquisition. In other words, when the filter is 'up'
it impedes language acquisition. On the other hand, positive affect is
necessary, but not sufficient on its own, for acquisition to take place.
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. It should be clear, however, that examining
irregularity, formulating rules and teaching complex facts about the target
language is not language teaching, but rather is "language
appreciation" or linguistics.
The only instance in
which the teaching of grammar can result in language acquisition (and
proficiency) is when the students are interested in the subject and the
target language is used as a medium of instruction. Very often, when
this occurs, both teachers and students are convinced that the study of formal
grammar is essential for second language acquisition, and the teacher is skillful
enough to present explanations in the target language so that the students
understand. In other words, the teacher talk meets the requirements for
comprehensible input and perhaps with the students" participation the
classroom becomes an environment suitable for acquisition. Also, the filter is
low in regard to the language of explanation, as the students" conscious
efforts are usually on the subject matter, on what is being
talked about, and not the medium.
This is a subtle
point. In effect, both teachers and students are deceiving themselves. They
believe that it is the subject matter itself, the study of grammar, that is
responsible for the students" progress, but in reality their progress is
coming from the medium and not the message. Any subject matter that held their
interest would do just as well.
