ESL AND CONTENT-AREA INSTRUCTION
Content-based ESL is a
method that integrates English-as-a-second-language instruction with subject
matter instruction. The technique focuses not only on learning a second
language, but using that language as a medium to learn mathematics, science,
social studies, or other academic subjects. Although this approach has been used
for many years in adult, professional, and university education programs for
foreign students, content-based ESL programs at the elementary and secondary
school levels are just emerging. One of the reasons for the increasing interest
among educators in developing content-based language instruction is the theory
that language acquisition is based on input that is meaningful and
understandable to the learner (Krashen, 1981, 1982). Parallels drawn between
first and second language acquisition suggest that the kinds of input that
children get from their caretakers should serve as a model for teachers in the
input they provide to second language learners, regardless of age. Input must be
comprehensible to the learner and be offered in such a way as to allow multiple
opportunities to understand and use the language. If comprehensible input is
provided and the student feels little anxiety, then acquisition will take place.
Krashen posits a dichotomy between acquisition and learning, with one
(acquisition) serving to initiate all language and the other (learning) serving
only as a monitor or editor, activated when the learner has time and is focusing
on the correctness of his or her language. In another dichotomy, Cummins (1979,
1981) has hypothesized two different kinds of language proficiency: basic
interpersonal communication skills (BICS), which are language skills used in
interpersonal relations or in informal situations; and cognitive academic
language proficiency (CALP), which is the kind of language proficiency required
to make sense of and use academic language in less contextually rich (or more
context-reduced) situations. Cummins suggests that BICS are relatively easy to
acquire, taking only 1 to 2 years, but that CALP is much more difficult, taking
5 to 7 years and necessitating direct teaching of the language in the academic
Many content-based ESL programs have been developed to provide students with
an opportunity to learn CALP, as well as to provide a less abrupt transition
from the ESL classroom to an all-English-medium academic program. Content-based
ESL courses whether taught by the ESL teacher, the content-area teacher, or some
combination provide direct instruction in the special language of the subject
matter, while focusing attention as much or more on the subject matter itself.
MATHEMATICS AND ESL
The language of mathematics has its own
special vocabulary, syntax (sentence structure), semantic properties (truth
conditions), and discourse (text) features. Unlike natural language, however,
math texts: (a) lack redundancy and paraphrase, (b) are conceptually packed, (c)
are of high density, (d) require up-and-down and left-to right eye movements,
(e) require a slower reading rate than natural language texts, (f) require
multiple readings, (g) are made up of a variety of symbols such as charts and
graphs, and (h) contain a great deal of technical language with precise meanings
(Bye, 1975). These language features, when combined with the mathematics content
of the written text, require the student to apply mathematics concepts,
procedures, and applications they have already learned.
The classroom environment in which ESL is taught through mathematics content
should be carefully structured so that second language acquisition can occur.
Instructional activities should promote second language development through a
natural, subconscious process in which the focus is not on language, but on
communicating per se the concepts, processes, and applications of mathematics.
Instructional activities in both the ESL and mathematics classroom should be
built on students' real-life experiences and prior knowledge of mathematics, and
offer situations in which students can interact with the teacher and fellow
students. Lessons that teach new concepts in mathematics should use graphics,
manipulatives, and other hands-on, concrete materials that clarify and reinforce
meanings in mathematics communicated through language. Studies have shown that
limited-English-proficient students can acquire both mathematics and English
simultaneously when they are involved in interactive activities (Wilson,
DeAvila, & Inili, 1982; DeAvila & Duncan, 1984).
SCIENCE AND ESL
Science is generally defined as a set of
concepts and relation- ships developed through the processes of observation,
identification, description, experimental investigation, and theoretical
explanation of natural phenomena. Through scientific inquiry, students develop
learning processes inherent in thinking: observing, classifying, comparing,
communicating, measuring, inferring, predicting, and finding space and time
relationships. Current approaches to science and second language education based
on research and classroom practice indicate a set of central notions for
relating science and ESL. Science inquiry facilitates the development of ESL by
providing the following: -a "sociocognitive conflict" that spurs development of
a new language system; -a source of meaningful and relevant language input,
using hands-on materials and texts with extralinguistic devices (diagrams,
charts, pictures) to clarify meaning; -positive affective conditions of high
motivation and low anxiety; -extensive opportunities for small group
interactions in which students negotiate meanings and receive comprehensible
language input; -opportunities for heterogeneous grouping with the role of peer
tutor alternating among students, factors that contribute to input, interaction,
and a positive, affective climate; -experience with a wide range of language
functions; -extensive vocabulary development needed for school success; -the
integration of all modalities of language use: listening, speaking, reading, and
writing; -literacy-related tasks for development of cognitive/academic language
proficiency; and -the use of prior cultural and educational experiences for
developing new concepts.
Science gives a rich context for genuine language use. From a language
acquisition perspective, science can serve as a focal point around which oral
language and literacy in ESL can develop. Specifically, science offers:
-interesting, relevant, and challenging content;
-opportunities for students to negotiate meanings;
-an abundance of appropriate language input;
-conditions for keeping students involved;
-material for development of reading;
-activities for development of writing; and
-experiences with the forms and functions of English.
SOCIAL STUDIES AND ESL
An ESL/social studies class should
be concerned with more than just historical facts, geography, and terminology.
It can promote the development of critical concepts of American history, thereby
helping culturally different students to understand their new country, the
United States, and its origins. Teachers can use language classes as a means of
expanding social studies knowledge as well as use social studies content to
enhance language development. Conventional instructional activities may be
adapted by teachers not only to enhance LEP students' language development and
knowledge of social studies, but to develop their cognitive skills as well.
-"Use of Manipulatives and Multimedia materials." Students need visual
materials to understand time periods in history; for example, photographs and
prints, realia, and filmstrips help students understand ways of life of the
Americans living in the Colonial period.
-"Language Experiences." Teacher guides students' spontaneous speech by
targeting specific vocabulary structures and concepts from the stories elicited
from the students. For example, in an intermediate-level ESL social studies
class studying the role of the Constitutional Convention in writing the U.S.
Constitution, the concept of reaching compromises to make decisions may be an
entirely new idea. The social studies teacher needs to determine whether the
students can either recall aspects from their own experiences that might be
similar, such as the various lawmaking bodies of their countries. If the
students do not clearly understand the topic, then the teacher can create an
experience that the students can draw from later. For example, the students
could role-play various scenes from colonial times, when power was concentrated
in the hands of a few. They could represent different interest groups, each
arguing to have certain laws passed. With the teacher as facilitator, the
students will come to understand that they must give up certain wants if any
progress is to be achieved. Once the students have understood the concept of
compromise, the teacher can proceed with the lesson on the Constitution and how
its laws were created.
-"Semantic Webbing." Students learn how to perceive relationships and
integrate information and concepts within the context of a main idea or topic
(Freedman & Reynolds, 1980). Following an oral discussion or reading,
students construct web strands and supports by putting key words or phrases in
boxes. Boxes are connected to illustrate relationships and subheadings under the
main idea, greatly aiding comprehension. For example, the students draw boxes
with the events that led to the American Revolutionary War.
Content area teaching of English as a second language is not an end to itself
but a means to an end. The strategies used for LEP students in social studies,
mathematics and science classes equip them with skills that will help them
achieve success in the mainstream classroom.
