The document discusses input, interaction, and second language acquisition from multiple perspectives. It begins by defining input and noting three views on input in language acquisition: behaviourist, nativist, and interactionist. It then examines foreigner talk studies, discourse analysis, and input/interaction in classroom settings. Research on motherese and first language acquisition is also summarized. The document provides an overview of different frameworks for analyzing classroom interaction, including interaction analysis, classroom process research, and teacher talk analyses.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

3. INPUT
Input
is used to refer to the languag
that is addressed to the L2 learner
either by a native speaker or by
another L2 learner.
Interaction is the conversation
constructed by the learner and his
partners.
Therefore, input is the result of
interaction.
8. The
environment is the crucial
determining factor.
Learners learn language in the form of
stimuli and feedback
Stimuli and
feedback
occur in the
environment
9. - Look at friends‟ models imitate
practice produce
- Suitable stimuli is important good
models
- Feedback is used to reinforce or correct
students to change their behaviors
16. ‘Motherese’ and L1 acquisition
The nature of ‘motherese’
Linguistic properties of mother’s speech:
well-formed, containing few ungrammatical
utterances or sentence fragments
formal adjustments: lower mean length of
utterance, use of simple sentences, use of
tutorial questions
adjustments in pronunciation:
pitch, intonation, rhythm
17. ‘Motherese’ and L1 acquisition
The nature of ‘motherese’
‘motherese’ – a simple style of language of the
type that parents use when speaking to their
child
18. ‘Motherese’ and L1 acquisition
The functions of ‘motherese’
Three main functions:
an aid to communication
a language teaching aid
a socialization function
(Ferguson, 1977)
19. ‘Motherese’ and L1 acquisition
The basis of adjustments made by
mothers
How speech modifications determined?
parents have a general idea of children’s
linguistic ability
parents internalize a model of a ‘typical’ child
of a given age
(Gleason & Weintraub, 1978)
20. ‘Motherese’ and L1 acquisition
The effects of ‘motherese’
The route of acquisition:
not change in any significant way
The rate of acquisition:
considerable effect
21. ‘Motherese’ and L1 acquisition
Explaining the effects
How input affects L1 acquisition?
Interactional routines – regularity and invariance
of utterances (Ferrier, 1978)
Three types of language lessons to communicate
with children (Clark & Clark, 1977):
conversational lessons
mapping lessons
segmentation lessons
25. The description of foreigner talk

(1) NS-NS speech
NS: When did you finish?
NS: Ten.
(2) Foreigner Talk-modification in form only
NS: What time you finish?
NNS: Ten o'clock.
(3) Foreigner Talk-modification in function only
NS: When did you finish?
NNS: Urn?
NS: When did you finish?
NNS: Ten clock.
NS: Ten o'clock?
NNS: Yeah.
27. The description of foreigner talk
3 types of foreigner talk:
Foreigner talk consisting only of interactional
adjustment
Foreigner talk consisting of interactional and
grammatical input adjustments
Foreigner talk consisting of interactional
adjustments as well as both grammatical and
ungrammatical input adjustments.
28. The explanation of foreigner
talk
Hatch (1983b) suggests the functions of
foreigner talk:
Promote communication
Establish a special kind of affective bond
between NS and NNS.
Serve as an implicit teaching mode
29. The explanation of foreigner
talk
Why adjustments occur?
To simplify utterances
To clarify what the native speaker wishes to
say
To discover what the native speaker has said
30. The explanation of foreigner
talk
The use of ungrammatical foreigner talk
depends on
NNS‟s proficiency in L2
Social status
NS „s prior experience of foreigner talk
Spontaneous occurrence of the conversation
31. The explanation of foreigner
talk
How adjustments take place?
Regression
Matching
Negotiation
33. DISCOURSE ANALYSIS
•Input not determined solely by the native
speaker, but also by the learner himself
•Learner‟s output serve as input to his own
language processing mechanisms.

35. Discourse analysis
The types of discourse learners take part in
depend very much on who the learner is.
36. Conversations involving child learners
Hatch (1978) shows that in child-learner discourse
* First stage
o-conversations start by calling for adult‟s attention
o-the adult responds by identifying the object
o-the child repeats the name of the object
37. Hatch (1978) shows that in child-learner discourse
*Development stage
o-The adult demands some comment on the
nominated topic
attempt at elaboration by the child
(for further comments of the adult, further
developments can continue to occur)
38. Wagner-Gough (1975) looked at the discourse
strategies by one child learner, Homer.
Homer frequently imitates the adult‟s previous
utterance
He also incorporates chunks of speech from the
previous discourse into his own utterances
Ex: What this is Homer?
What is this is car?
39. Peck (1978, 1980)
focus functions
Ex: NS child: you know why?
L2 child: you know why?
substitution functions
Ex: NS child: there one piece
L2 child: there different piece.
Child-child conversation: more functions (the
child may be able to explore and expand the limits
of his L2 competence
Child-adult conversation: fewer functions (adults
tend to employ more questions and requests for
clarification)
40. Conversations involving adult learners
o-The adult learner has difficulty in identifying
the topic.
o- Repair strategies are common on the native
speaker‟s part.
41. adult-adolescent learner adult-child learner
the adolescent learner is
expected to play a much
bigger part in keeping the
conversation going.
the adult native speaker
has a great responsibility
and dominate the
conversation by using
frequent rhetorical
questions and repetition.
Krashen (1982) speculates that because older
learners are more involved in keeping conversation
going, they may learn more rapidly than younger
learners.
42. The negotiation of meaning
The learner and native speaker together strive to
overcome the communicative difficulties
negotiation of meaning
strategie
s
tactics
• Conversational device to avoid
trouble
• Ex: stopping topic control, selecting
salient topic, checking
comprehension
• Devices for repairing trouble
• Ex: topic switching or request for
clarification
43. Checking comprehension
NNS: I was born in Nagasaki. Do you know
Nagasaki?
Request for clarification
NNS1: ……research
NNS2: Research, I don‟t know the meaning.
44. Topic switching
NNS1: Are you going to attend today‟s
party?
NNS2: I don‟t know yet, but probably I‟ll
attend.
(long pause…) So when will you go back to
Japan?
45. Other devices (using a slow space, repeating
utterances, stressing key words) both tactics
and strategies
** Negotiation makes input comprehensible
promote SLA
47. Overview
It was recognized that successful
outcomes may depend on the type of
language used by the teacher and the
type of interactions occurring in the
classroom.
It was hypothesized that classroom
interaction was the major variable
affecting SLA in formal settings.
49. Interaction analysis
It was initiated in subject classrooms.
In 1960s, Flanders developed a
category system for analyzing the
communicative uses of the teacher‟s
and pupils‟ language. Later, this
system was adapted for use in
language classroom.
More sophisticated system have been
devised by Fanselow (1977) and
Allwright (1980).
50. Interaction analysis
Classroom interaction can be accounted
for in terms of three types of analysis:
A turntaking
analysis
A topic
analysis
Allwright (1980)
A task
analysis
51. Problems about the
systems
The categories selected are no more
than “subjective hunches”.
They code surface behavior and so
miss the communicative value of
remarks => Although such systems
may achieve reliability, their validity
and relevance are in doubt.
(Long, 1980)
