3. OUTPUT HYPOTHESIS
“Output”, (1980) indicates the outcome of what the
student has learned.
The Output hypothesis states that it is the action of
producing language, speaking and writing, which
develops part of the process of second language
learning (how proficient learners become). Swain
(1985)
4. Three functions of output
1) the noticing/triggering function
2) the hypothesis-testing function
3) the metalinguistic (reflective) function.
This means that the message needs to be conveyed
precisely, coherently, and appropriately. This form of
‘pushing’ students in terms of output is precisely the
same as that of Krashen’s comprehensible input notion
of i +1.
6. Krashen´s (1985) states that comprehensible input is the only
true way a learner has to acquire a second language.
7. INPUT
Krashen´s input hypothesis which states that we
acquire the target language only when we understand
language (comprehensible input). In addition, in
order for learners to understand a language point, the
structure must be just "a little beyond" where students
are at the moment and they will use cultural baggage.
8. CONCLUSION
Input hypothesis Output hypothesis
Krashen stressed that Consequently, the feedback

principle of Krashen´s theory stated, production challenged
states that input should not learners to focus on the means

as such sequencing is not it is necessary to enhance and
needed; thus, students would develop the target language

behind. to language acquisition.
9. CONCLUSION
Both theories complement each other as all the elements
mentioned, strongly contribute to language acquisition.
One aspect to be taken into account is the positive
environment a teacher must create during his/her lesson as
it makes a difference in the students’ motivation and
interest in acquiring the second language.
Feedback plays an important role as well as correct
production, and interesting, appealing and meaningful
materials which may challenge and motivate learners.
