Did you know?
There
are sixty-six native
languages, other than English,
spoken by students in some
school districts.
Language Diversity
Three in four English Language Learners’ first language is
Spanish.
Other languages spoken by public school children include
Vietnamese, Hmong, Cantonese, Korean, Haitian, Creole,
Arabic, Russian, Tagalog, Navajo, Khmer, Mandarin,
Portuguese, Urdu, Serbo-Croatian, Lao, Japanese, Punjabi,
Armenian, Polish, French and Hindi.

Hispanics/Latinos in the
United States
The United States has the second largest Spanish speaking
population in the world.
More than 53 million Hispanics/Latinos in the U.S.(Pew
Hispanic Center, 2010).
Come from every Spanish speaking nation in the world.
The majority of Hispanics in the United Sates (66%)
identify as Mexican, Mexican-American or Chicano (2006).
The majority of Hispanics/Latinos live in 5 states.

Hispanics/Latinos in U.S. Schools (K-12)
The number of Hispanic/Latino students has doubled in the last 15
years.
There are approximately 10 million Hispanic/Latino students in the
K-12.
One in five public school students in the United States is
Hispanic/Latino.
By 2040, the U.S. Census Bureau has projected that there will be more
Hispanic/Latino children in U.S. schools than non-Hispanic/Latino
children.
Use of the Spanish Language
By youth under the age of 18
U.S. Born – approximately 70% speak Spanish in
their homes
Foreign born– more than 90% speak Spanish at
home
Reflection
Let’s pause for 10 minutes and take some time to reflect on what this
information means for our K-12 mathematics classrooms.
Each of you has a different colored paper in front of you. On that piece
of paper write down
1) 2 things that you have learned, &
2) 1 question that you have
Find the person who has the same colored paper as you and discuss your
thoughts.

What has been the response to
linguistic diversity in the U.S. K12 classroom?
Objectives of Bilingual Education
Not allow students to fall behind in academics because
of lack of command of English.
Gradually learn English as a second language.
Ease the transition from the native language to English
through subjects.
Offer more opportunity for academic success through
ease of transition into English.
Models Of Bilingual Education
English immersion
Transitional bilingual education
Maintenance bilingual education
Two-way bilingual education – Dual Language
Immersion
English as a second language (ESL)
Immersion
Instruction is entirely in English.
All subject content and communication is
conducted in English.
There is no instructional support for native
language.
Transitional and Maintenance models
Instruction for some subjects is in the
students’ native language but a certain
amount of each day is spent on
developing English skills.
Classes are made up of students who
share the same native language.
One-way or Two-Way Immersion
Instruction is given in two languages.
Teachers usually team teach.
This approach is also called dual
language immersion.
English as a Second Language (ESL)
May be the same as immersion but also may include
some support to individuals in their native tongue.
Typically classes are comprised of students who
speak different languages but are not fluent in
English.
Students may attend classes for only a period a day,
to work strictly on English skills, or attend for a full
day and focus both on academics and English.
Arguments Against Bilingual Education
Keeps students in a cycle of native
Massachusetts 2002 mid-year
referendum Question 2
Arizona Proposition 203 – similar
to California proposition.
Implemented fall 2001.
California Proposition 227 –
approved in 1998 by California
voters to basically eliminate
bilingual education. Most LEP
students are now in immersion
programs.*
language dependency.
Costly
Ineffective compared to the amount
of money invested
Is not systematized
Reflection
How does Moises’ (the boy in the movie) resemble students in the
schools in which you are teaching/working?
How do you and the teachers in your schools address the needs of
students such as Moises?
Comprehensible Input
How is mathematics understood by English Language Learners?
Language Acquisition General
Everyone agrees that human beings are born with the
ability to learn language (to speak)
We use language to communicate.
2 schools of thought of how we learn language
Behaviorist – we learn language through modeling.
Innatist – we are born with a mechanism that
monitors grammar (the structure of language).
Krashen SLA Hypotheses
The Natural Order Hypothesis - 'we acquire the rules of language in a
predictable order'
The Acquisition/ Learning Hypothesis - 'adults have two distinctive ways of
developing competences in second languages .. acquisition, that is by
using language for real communication ... learning .. "knowing about"
language' (Krashen & Terrell 1983)
The Monitor Hypothesis - 'conscious learning ... can only be used as a
Monitor or an editor' (Krashen & Terrell 1983)
The Affective Filter Hypothesis - 'a mental block, caused by affective factors
... that prevents input from reaching the language acquisition device'
(Krashen, 1985, p.100)
The Input Hypothesis - 'humans acquire language in only one way - by
understanding messages or by receiving "comprehensible input"’ *
Input Hypothesis
BICS & CALP
BICS – Basic Interpersonal Communication Skills
Sometimes referred to as playground communication.
Immigrant and non-immigrant children learn this type of
communication first.
Communication is informal.
CALP – Cognitive Academic Language Proficiency
Formal language used in academic and professional environments.
This type of communication is learned through modeling by an
adult.
Is not often used outside of the classroom or professional
environment.

for the Math Classroom
Listen with Comprehension
Use Academic Vocabulary

Lexicon of Mathematics
The terms that are used by mathematicians and math learners use to
talk about mathematics.
Content specific
Uses of language are specific to mathematics
quadratic, function, algebraic, geometric, sine, cosine
Words that have a specific meaning when used in the math
classroom
Positive, negative, about, rational, irrational, infinity, imaginary
(refer to handout for discussion)
6 Steps for Teaching Vocabulary
Identify words all students need to know
Identify words English Learners need to know
Select the highest-priority words
Choose key words for a day’s lesson
Build from informal to formal understanding
Plan many opportunities to apply key words

Now it’s your turn to play
There are several problems on the table
Read the problem and solve (if you want to)
How would you scaffold this problem for
understanding?
Write down your strategies
Find a partner and discuss your strategies
Write down both of your strategies on a large paper and
place on the wall for group discussion
