Learning and Acquisition
When the students have learnt everything they need to know about a
language then this learning will turn into acquisition (like the
understanding you have of your first language).
According to Krashen (1976,1982,1988) Learning about a language -
its rules etc, - cannot turn into acquisition (knowing about a
language). Acquisition can take place without learning and is a
subconscious process. Learning takes place in a formal environment
such as a school.
This hypothesis was just one of five parts of Krashens’ Monitor
Model of Second Language Acquisition. This was very influential and
led to a lot of debate and further research.
We shall therefore look at the five hypotheses that make up The
Monitor Model.
Krashen’s monitor model
Krashen’s monitor model is made up of ____ hypotheses:
Acquisition-learning hypothesis.
Acquisition is the way children _______ their first language.
Learning is a conscious process of study. Acquisition is more
important. Only acquired language is _________ for fluent
communication. Learning cannot become acquisition.
Monitor hypothesis
Learners monitor what they are saying or writing and correct it.
They only do this when they are really concerned about formal
correctness and when they have ____ to do so.
Natural order hypothesis
Second language learners acquire the features of the second
language in a ___________ order. This natural order is ___________
of the order in which rules have been learned in language
classes.
Input hypothesis
Learners acquire language in one way – by ________ to
comprehensible input. If the input contains language just ______
the current level of the learner, then comprehension can occur and
acquisition will occur.
Affective filter hypothesis
‘Affect’ refers to motives, needs, _________ and emotional states.
If a learner is tense or _____, for example, they will ‘filter out’
input, making it ___________ for acquisition.

A Native Speaker Environment
Simply placing students in a second language environment in the
hope that the students will learn the language is not enough. The
language must be used in such a way that students understand the
messages. To access the messages, students rely on context,
knowledge of the world, and other clues including gestures,
examples, illustrations, and caretaker language.
Students acquire more language when they are exposed to language
which is comprehensible and just slightly above their current level
of competence; for this reason, teachers must offer strategies for
making the material accessible.
Also, teachers must be especially careful to challenge students
without frustrating them. Anxiety and lack of motivation result
when there is too great a difference between the students' level of
language proficiency and the level of language they must
understand. When the language is too far beyond the students'
current level of proficiency students conclude that they cannot
learn the language.
(See also Krashen’s input hypothesis.)
Correction
Systematic grammatical correction of errors does not improve the
learners' language abilities. On the contrary it may hinder their
motivation to use the language by placing emphasis on the form
rather than the message. Also students are not always ready to take
in the information the teacher is offering through correction.
More effective feedback includes rephrasing and expanding on what
the students have expressed.

1999.
Students need to learn grammar and vocabulary before they can
speak.
The practice of learning words and breaking down
and analyzing language components do not lead to language
production nor do they lead to proficiency if they are taught
without meaningful communication.
While grammar and vocabulary are essential parts of language, they
are only enablers, which allow students to communicate.
Students learn a second language more easily if they engage in meaningful activities requiring the use of the language and its components. For example, students need to know the correct form of verbs so that they can use the verbs to talk about their daily activities.

Teaching.
Stages
To become proficient in another language, students must progress
through various overlapping stages spanning several years:
Pre-production/Comprehension Stage:
Students communicate with gestures and actions. They build
receptive vocabulary and refine their listening skills. During this
phase, called the “silent period,” students try to make sense of
what they hear, but they do not engage in language production. Even
though they do not speak, language acquisition has begun.
Early Production Stage:
Students speak and/or write using yes/no answers, one or two words,
lists of words, or short phrases. They continue to expand their
receptive vocabulary.
Speech Emergence Stage:
Students' speech production improves in both quantity and quality.
Students speak and/or write in longer phrases and complete
sentences and they use a wide range of vocabulary.
Intermediate Fluency Stage:
Students engage in conversations and produce connected narratives
orally and in writing.
Advanced Stage:
Students speak and write in connected and unified paragraphs about
most situations.
Understanding that students are going through a series of
developmental stages helps teachers to predict and accept a
student’s current stage and they can then adapt their teaching to
encourage a students progress to the next stage.

Language Learning
Cognitive theories of SLA
Individual learners and their thought processes are different – their cognitive abilities differ. These cognitive abilities include their ability to learn languages – some have a natural talent for learning languages others do not. Learners strategies differ – some have good techniques for learning, some have good memories Learner motivation is different their confidence/anxiety differs and their own belief in their ability also seems to affect success.
Factors which may influence language learning:
Intelligence
Aptitude
Personality
Motivation
Attitudes
Age of Acquisition.
Recognition of the above has influenced much research into classroom interaction. Researches looked at: Communication between teachers and learners. They considered teachers’ questions, learner responses, teachers’ feedback and learners taking turns when speaking. They also looked at interaction and communication between learners and their communication strategies. As a result there was a shift from traditional language instruction to communicative task based language teaching.
