2. The Comprehension Hypothesis
It begins when we acquire language, when we understand messages, when we understand what people tell us and when we understand what we read.

3. The Comprehension Hypothesis also applies to literacy: Our reading ability, our ability to write in an acceptable writing style, our spelling ability, vocabulary knowledge, and our ability to handle complex syntax is the result of reading.
Few years ago, He referred to this hypothesis as the Input Hypothesis. He preferred “Comprehension Hypothesis,” because it more accurately reflects what the hypothesis says.

4. The Comprehension Hypothesis refers to subconscious acquisition, NOT conscious learning.
A strong affective filter prevents input from reaching those parts of the brain that do language acquisition.

5. Krashen's Five Hypotheses
Krashen's Comprehension Hypothesis Model of L2 learning  
Krashen's Five Hypotheses
The Natural Order Hypothesis
'we acquire the rules of language in a predictable order'
TheAcquisition/ Learning Hypothesis
'adults have two distinctive ways of developing competences in second languages .. acquisition, that is by using language for real communication ... learning .. "knowing about" language' (Krashen & Terrell 1983)
The Monitor Hypothesis
'conscious learning ... can only be used as a Monitor or an editor' (Krashen & Terrell 1983)
The Input Hypothesis
'humans acquire language in only one way - by understanding messages or by receiving "comprehensible input"'
TheAffective Filter Hypothesis
 'a mental block, caused by affective factors ... that prevents input from reaching the language acquisition device' (Krashen, 1985, p.100)

6. Acquisition
Learning
implicit, subconscious
explicit, conscious
informal situations
formal situations
uses grammatical 'feel'
uses grammatical rules
depends on attitude
depends on aptitude
stable order of acquisition
simple to complex order of learning
NOTE:
"Explicit" means "something that is easily understood or told directly and clearly" whereas "Implicit" means "something that is not expressed clearly, thus not clearly understood".
Aptitude is your capacity ability to do something. Attitude is your behavior toward something. For this job position your aptitude to raise children will be tested You better change your attitude, right now.

7. Evidence for the Input Hypothesis (Krashen 1985)
Examples I)
people speak to children acquiring their first language in special ways
II)
people speak to L2 learners in special ways
III)
L2 learners often go through an initial Silent Period
IV)
the comparative success of younger and older learners reflects provision of comprehensible input V)
the more comprehensible input the greater the L2 proficiency
VI)
 lack of comprehensible input delays language acquisition
VII)
teaching methods work according to the extent that they use comprehensible input
VIII)
immersion teaching is successful because it provides comprehensible input
IX)
bilingual programs succeed to the extent they provide comprehensible input

9. L2 learners often go through an initial Silent Period

L2 learners often go through an initial Silent Period

10. The more comprehensible input the greater the L2 proficiency
Lack of comprehensible input delays language acquisition
HOW DOES
“COMPREHENSIBLE INPUT”
APPEAR IN THE CLASSROOM

11. Teaching methods work according to the extent that they use comprehensible input
Bilingual programs succeed to the extent they provide comprehensible input

13. PERSONAL COMMENT  The Comprehension Hypothesis is a very important stage where the learners acquire a new language. It is a subconscious acquisition because it is reflected when students are acquiring new vocabulary without them realizing for that reason is NOT a conscious learning. When the learner is acquiring a new language, a strong affective filter prevents input from reaching those parts of the brain that do language acquisition. Finally when the learner acquires that new knowledge they learn it and beginning to write, to read and to speak. In the classroom it begins after the silent period, when students understand what the teacher say, when they understand what they are reading in the textbooks and finally they understand what people say. Finally the students begin to speak
