Krashen´s Theory of 2nd Language Acquisition. Krashen´s Theory of 2nd Language Acquisition consists
of five main hypotheses:
The Acquisition – learning hypothesis.
The Monitor hypothesis.
The natural order hypothesis.
The input hypothesis.
The Affective Filter hypothesis.

Krashen´s Theory of 2nd Language Acquisition. The Acquisition – learning hypothesis.
This hypothesis says
that
There are two independent systems
The learned system The acquired system is
The product of formal instruction and a conscious process.
is
The product of a conscious process.
Krashen says that “learning” is less important than acquisition.
Krashen´s Theory of 2nd Language Acquisition. The Monitor hypothesis.
Everyone has a monitor that tells them when something is good or bad. It requires these conditions: time, knowledge and focus on form.
MONITOR Conditions(you need…)
TIME KNOWLEDGE
FOCUS ON FORM
Have time to think. Know the rules (not have forgotten it).
Feel a need to use the correct form.
Krashen´s Theory of 2nd Language Acquisition. The Monitor hypothesis.
TYPES OF LEARNERS THAT USE THE MONITOR.
OPTIMAL MONITOR USER Uses the monitor appropriately.
UNDER MONITOR USER Does not care about correcting.
OVER MONITOR USER Uses the monitor all the time.
Krashen´s Theory of 2nd Language Acquisition. The natural order hypothesis.
This is a natural, predictable order in which people acquire language. It is the same for each person and independent of the instruction program.
Krashen´s Theory of 2nd Language Acquisition. The input hypothesis.
People acquire a language by receiving comprehensible input.This input should be slighly ahead of a learner´s current state of knowledge( i + 1 ).

Krashen´s Theory of 2nd Language Acquisition. The Affective Filter hypothesis.
When the learner is experiencing high anxiety, low - esteem or low motivation, the filter turns on and causes the learner to block out input.

Swain´s Output hypothesis. Output is a sign of learning and creates opportunity for each of the 3 functions.
Output promote noticing, the gap between what is said and what the learner wants to say.
Output test hypotheses of the learners and permits experimentation with the gap.
Learning happens through reflection on what happened with the experiment.

BICS Basic Interpersonal Communication Skills Tareas simples, mecánicas, Especialmente útil para estudiantes con dificultades
Los estudiantes bilingües necesitan la mayor cantidad de trabajo acá de manera que se asegure la comprensión mediante procesos concretos y ricos en contexto
Los estudiantes Bilingües deben ser llevados a lo largo de este eje para asegurar la comprensión
Ejercicios repetitivos como planas, dictados, desprovistos de contexto, poco significativos y poco demandantes a nivel cognitivo.

The Common Underlying Proficiency Theory (The Iceberg
Analogy)
Context Embedded and Context Reduced Communication
• Context embedded communication exists when there is a good degree of contextual support in communications, e.g. body language, gestures, intonation etc.
• Context reduced communication there are very few clues to meaning outside language.
