Introduction
Stephen Krashen
1. The Acquisition-Learning hypothesis
Explanation of the hypothesis

Acquisition: subconscious acceptance of
knowledge
through communication

Learning: conscious acceptance
grammar or form
Application for Teaching

use natural communication in the class
How acquisition & learning are used?

Acquisition system initiates an utterance.

Learning system monitors the utterance.

Monitor over-used can sometimes act as barrier.
Application for Teaching
Balance the accuracy and fluency
in students.
“Affective Filter performs like a ‘screen’ blocks the comprehensive input in learning to reach the acquisition part of the brain. And it is influenced by emotional variable that can prevent learning.”
When the filter is high, it
blocks the view.

When the filter is low, due
to relaxed environment, the
view is cleared.
The filter is comprised of such factors as:

Attitude
Motivation
Self-confidence
Anxiety
Application for Teaching:

-Cultivate the interest and use
it to motivate

-Increase learning confidence &
decrease language anxiety
The natural order hypothesis is the idea that children learning their first language acquire grammatical structures in a pre-determined, 'natural' order, and that some are acquired earlier than others. This idea has been extended to account for second language acquisition in Krashen's theory of language acquisition.
Example:
According to the natural order hypothesis, learners acquire the grammatical morpheme -ing before the morpheme third person -s.
For learners of English as a second language generally acquire the grammatical structure of yes-no questions before the grammatical structure of wh- questions.
Why it is important to know this theory?
According to Krashen, learners acquire parts of language in a predictable order. 

Attempts to get the learners to produce structures before they are ready to do so may fail.

The Applications of Natural Order Theory
This natural order of acquisition occurs independently of deliberate teaching and therefore teachers cannot change the order of a grammatical teaching sequence.

Language should be taught in order from easy to more difficult concept by using scaffolding.
Kranshen’s Input Hypothesis makes the following claims:

[Learners progress along the natural order by understanding input that contains structures a little bit beyond their current level of competence.]
How a learner acquires a second language?
This hypothesis suggests that language acquisition occurs when learners receive messages that they can understand a concept also known as “comprehensible input”.
However, Krashen also suggests that this comprehensible input should be one step beyond the learner’s current language ability, represented as i + 1.

It is applied only to language acquisition and not to language learning, posits the process that allows second language learners to move through the predictable sequence of the acquisition of grammatical structures predicted by the natural order hypothesis.
