Second Language Acquisition
Processes and Theories
Input Hypothesis
Developed by Krashen as part of his
Monitor Model
The belief that we acquire language in the
simple way of comprehensible messages.
Just hearing a language is not as effective as
seeing it presented with models messages
that can be understood.
In the classroom, teachers can apply this theory
to their instruction by making sure to use
models and kinesthetic lessons where an English
learner not only hears the language but can
comprehend the message through pictures,
symbols, models, and etc.
BICS vs. CALP
Proposed by Jim Cummins
A distinction should be made between basic interpersonal communicative skills and cognitive
academic language proficiency. BICS is an area of relatively quick fluency and conversation that a
student can pick up where CALPS is the reading and writing that has a longer trajectory to master.
Just because students can hold mostly fluent conversations does not mean they are at the level
where a educational test can be given without bias.
Often times English learners are thought to have learning disabilities when they
struggle with reading and writing though they speak fluently. Teachers should note
this distinction in language acquisition levels so as to not rush to conclusions that a
student has a learning disability but instead work with that student to build literacy
in the second language.
Universal Grammar
Proposed by Noam Chomsky
Chomsky proposes that all languages share a foundation of
innate building blocks. Verbs, nouns, adjectives, and etc. create
the foundation needed to understand any language. He
upholds the belief that children do not need to be taught
language as they can pick up the language through the broken
bits and pieces that they hear and apply the rules of verbs,
adjectives, nouns, and the like to interpret which words forms
sentences.
This theory could implicate that educators need not focus
on teaching a language to some extent but instead focus on
immersing the student in the language so they can use the
founding rules of their native language to understand the
sentence formations of the second language.
Interactionist Model
Developed by Long in 1980
The interactionist model promotes native to non-native, peer to
peer conversation as a means to enhance language proficiency.
Peer conversation exposes a second language learner to the
language and provides more opportunity for the language learner
to hear and practice using the language.
Teachers should promote conversation in the classroom.
Intentionally pairing students will not only give the language
learner more opportunities to grow but will give the native
speaker an opportunity to learn about the culture of his or her
peer. restricting language learners to specific tracks or classes
without native speakers will stifle opportunities to learn new
language formulas and grammar found in native conversation.
Semiotics
Discussed by
Chandler (2005),
Kress and Van
Leeuwen (1995), and
Scollon and Scollon
(2003)
Second language acquisition based on signs and symbols. Different visual
icons and symbols carry different meanings across languages. Semiotics
is a perspective of learning a language by understanding its signs,
symbols, icons, and etc. and what they mean.
In the classroom, music, collages, drawings,
animation, and other visual devices can be used to
display meaning. Students can use these tools to
identify messages and display comprehension of
concepts.
