1) The document discusses input and interaction in second language acquisition. It defines input as the language directed at the non-native speaker through listening and reading. Input must be comprehensible and slightly above the learner's level. 2) The document also examines Stephen Krashen's Input Hypothesis which posits that language is acquired through comprehensible input that is one stage above the learner's current ability. 3) Interaction involves face-to-face communication between language learners and promotes language development through receiving feedback and negotiating meaning.

3. Input in Second Language Acquisition
Input is language that goes
into your mind.
• Listening not speaking
• Reading, not writing or
memorization

4. Comprehensible input
Comprehensible input is incoming language that
you can understand.
• Can be mentally possessed in real-time
• Truly meaningful communication

5. EXAMPLE OF INPUT
• In the classroom
The most important and accessible input for
learners is that of the teacher. When teachers are
talking in classes they are providing
opportunities for learners to develop their
comprehension. Teachers can optimize this
opportunity by choosing the right levels of
complexity of vocabulary and structures, speed
of delivery, degree of clarity, and range of
register and style.

6. INPUT HYPOTHESIS (Stephen Krashen)
Second language input must be:
- Comprehended
- At one stage above the learner’s current
level (i+1)
In order to be acquired.

8. Caretaker speech
Many languages have special
speech registers for talking to
young children. These registers,
variously called baby-talk,
motherese, child-directed speech
& caretaker speech – have
characteristics that assist the
child’s acquisition of language.

9. Foreigner Talks
Foreigner talk is a simplified version of a
language that's sometimes used by native
speakers when addressing non-native speakers.

10. Teacher talk
Teacher talk is the kind of language used by the
teacher for instruction in the classroom.

11. Interlanguage talk
Interlanguage talk is defined as conversation
between two non-native speakers.

12. INTERACTION
• Interaction is a kind
of action that occurs as two
or more objects have an
effect upon one another.
12
• The Interaction hypothesis is a theory of second-
language acquisition which states that the
development of language proficiency is promoted
by face-to-face interaction and communication.

13. CONT…
• Interactions often result in
learners receiving negative
evidence. That is, if learners
say something that their
interlocutors (partners) do
not understand, after
negotiation the interlocutors
may model the correct
language form
13
• In doing this, learners
can receive feedback on
their production and
on grammar that they
have not yet mastered.

14. EXAMPLE OF INTERACTION
• One of the participants in
a conversation will say something that
the other does not understand; the
participants will then use
various communicative strategies to
help the interaction progress.
14
• The strategies used when negotiating meaning may
include slowing down speech, speaking more
deliberately, requests for clarification or repair of
speech, or paraphrases.
