THE COMPREHENSION HYPOTHESIS Stephen Krashen BY: ADRIANA PEREZ SANTILLAN ALEXIS CARDONA LUQUEÑO

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.

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.

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.

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)

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.

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

People speak to L2 learners in special ways People speak to children acquiring their first language in special ways People speak to L2 learners in special ways

L2 learners often go through an initial Silent Period The comparative success of younger and older learners reflects provision of comprehensible input L2 learners often go through an initial Silent Period

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

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

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
