Transcript of Krashen's Theory of Second Language Acquisition

The Affective Filter Hypothesis
Affective factors that block language acquisition:

Affective factors that open language acquisition:
*Natural setting
*Hands-on activities

Krashen's Theory of Second Language Acquisition
The Learning/Acquisition Hypothesis
*Rules and vocabulary

*Language use for other purposes
The Natural Order Hypothesis
"Krashen reviews research that shows that language, both first language and second language, is acquired in a natural order" (Freeman & Freeman, 2004, p. 36).

First Language Acquisition:
*Vowels before consonants
*Statements before questions
*Positive statements before negative statements

Second Language Acquisition:
*Spanish and Chinese speakers learning English:
-Plural "s" in nouns before third-person "s" in present-tense verbs

The Monitor Hypothesis
is what enables native English speakers to tell what sound is right in the language...The rules that people
can be used to monitor spoken or written output" (Freeman & Freeman, 2004, p. 37).

*Effective monitor use=
-Spending time
-Focusing on language form
-Knowing the rules

*Monitor use is easier with spoken language than written
The Input Hypothesis
"How does acquisition take place? According to Krashen, the key is comprehensible input--messages, either oral or written, that students understand" (Freeman & Freeman, 2004, p. 38).

*i+1= Input slightly beyond a student's ability to understand
*Comprehensible input= modification to accommodate all levels
-Use pictures, gestures, tone, interactive activities
