My colleague, Dr. Julie Mathews-Aydinli, did the following research on
the topic of how the number of students in the second language classroom
affects their learning of the language and found basically that the
research backs teacher perceptions that large classes are a negative
factor in learning the language. Below is a summary (in her words) of
the research, bibiliographic info, and abstracts of all the research she
looked at. It's long but detailed. She highlighted and bolded important
sections - but I don't know if those marking will make it to the list.
At any rate, hope this helps make the case...

from Julie:

Here's my final report!



If we look at the research over the last 25 years, there is generally a
consensus that supports what most teachers would report, that large
classes are a negative factor in effective teaching and learning of a
second language. Several research studies have shown the negative
affects of large classes (e.g. Coleman, 1989; Gonzales, 2003; Oberg,
1993; Ozerk, 2001; Tsuji, 1989). Many others provide further anecdotal
evidence of large class size as a problem (e.g. Berney & Stern, 1990;
Leki, 2001; and Morgan, 2000), and a theoretical article in TESOL
Quarterly strives to provide a model for understanding the various ways
that large class size negatively affects second language learning
(LoCastro, 2001).



Still, there are studies that suggest that large class size is in fact
not a problem. A closer look at these studies seems to reveal a couple
of possible qualifications for such an assessment of the class size
issue. First, many of these studies (e.g. Elango, 1993; Kumar, 1993;
Vuppala, 1993) are English as a Foreign Language studies, and are based
in contexts in which even the researchers admit that large classes are
an "inescapable aspect" of language teaching (Vuppala, 1993). One would
have to question therefore whether the findings of these studies, many
of which emphasize also seeking ways to find benefits in the large class
size, are simply attempts to make the best of a bad situation, rather
than actual 'proof' that large classes are a positive thing. The other
type of study that tends to argue large classes are not a problem also
has a caveat of sorts, that they usually look at large language classes
in which other, innovative approaches are in place (e.g. Knight, 2000).
For example, Bolton (1988) is a study from a community college ESL class
in which a teacher opted to redistribute three classes of 25 students
into one class of 75 but then use the extra time to give tutorials and
group conferences etc. With these extra activities, a statistical
comparison on the performance of the students in the large group with
that of students in regular smaller classes was not significantly
different. If anything, there were suggestions that the large group
students performed slightly better. One would automatically question
however whether there might not have been some effect of the teacher and
students putting 'extra' effort into this new and experimental situation
that may have caused some problems for purely statistical validity.



Looking at the research overall therefore, I think one has to agree that
it confirms teachers' widespread perceptions that large classrooms not
only make teaching more difficult, but that they also have negative
affects on the students' learning.

suggested.
Fifteen problems of language pedagogy related to class size are
grouped under pedagogical, management-related, & affective
categories. The importance of learners' opportunities to interact
with
the target language, supported by various recent hypotheses,
suggests
that the maximum number of students for effective language learning
in

Title
Effects of ESL Time and Class Size on the Achievement of LEP Students.
Date of Publication
November 1993
Abstract
A study investigated the relative effect of 45-minute and 90-minute
daily instruction in English as a Second Language (ESL) on limited
English proficient (LEP) first-graders' language and overall
achievement. The subjects were two groups of pupils from different
schools: (1) 13 pupils from 7 language backgrounds, receiving 45 minutes
of instruction daily; and (2) 17 pupils representing 5 native languages,
receiving 90 minutes of instruction. Data used for analysis included
reading and language test scores, oral language proficiency test scores,
and teacher-provided information on overall grades. Results indicate
that the pupils in shorter ESL class, which was also smaller, made
higher grades in the regular classroom than did the other group. The
short-class group also had higher oral proficiency test scores, but not
significantly higher reading and language test scores. It is concluded
that class size and time may have some significant effect on regular
classroom achievement and oral language achievement but not may not
affect scores on standardized achievement tests. (MSE)

Abstract
This report confirms anecdotal evidence that language teachers do find
large classes to be problematic, collates data on class sizes in various
parts of the world, and investigates the possibility of defining a large
class, at least from the teachers' points of view. The first section is
introductory. The second presents findings of a small-scale (n=46)
investigation of the perceptions of native-speaking and
non-native-speaking teachers of English as a Second Language (ESL) of
the characteristics of large classes. The third section describes a
larger study of ESL teachers' experiences with and perceptions of class
size in Great Britain, Turkey, Indonesia, Madagascar, Mali, Japan,
Greece, Jordan, and Spain. Section 4 discusses what the study tells
about actual class sizes, and section 5 is a detailed analysis of the
relationship between teachers' experiences and their perceptions of
class size. It is concluded that class size varies across countries and
probably across institution type. No evidence that teachers share a
universal conception of ideal class size was found, but there appeared
to be a positive correlation between the largest class regularly taught
and both perceptions of an ideal class and perceptions of what a large
class is. Further research is recommended. (MSE)

Abstract
This is the second of 12 research reports on the phenomenon of
language instruction within a large class environment. The report is
written in five sections. The second section (following the introductory
first section) discusses the reasons for studying large classes in
language instruction, including the facts that teachers find large
classes cause difficulties that affect teaching performance, that large
classes are becoming commonplace, and that very little has been done to
address the problem or train English-as-a-Second-Language (ESL) teachers
to instruct under such difficult circumstances. The third section
outlines and explains the project's activities, namely, creating a
bibliography, networking, organizing colloquia, and promoting and
undertaking research. Section 4 presents the nine specific questions
that the project is attempting to study. These include the following:
the teacher's concerns, the extent of the large class phenomenon, the
reasons for the occurrence of large classes, attitudes towards large
classes, data collection in large classes, the performance of large
classes, strategies in large classes, language acquisition in large
classes, and experiments in large classes. Section 5 summarizes and
presents conclusions. (GLR)

Title
A Research Report on the Toronto Board of Education's Response to
Adult Literacy.
Date of Publication
May 1989
Abstract
Since 1985, the number of adult literacy programs provided by the
Toronto Board of Education has increased by 500 percent and learners by
almost 300 percent, so that in 1989, almost 9,000 adults are enrolled in
nearly 700 classes. Two distinct groups are being served: a unilingual
group, most of whom are Canadian-born, English-speaking young adults,
and an English as a second language (ESL) group who are typically
literate in a language other than English. The differences between the
two groups have consequences for program planning, instructional
methods, locations of classes, and outreach. Classes are scheduled at
most times of the day. Unilingual learners tend to take more hours of
instruction per week than ESL learners. Generally, all learners are
pleased with their classes, although few attend for more than a year,
and the dropout rate is high. Gains for unilingual learners are
associated with good attendance, amount of instructor's experience, and
a classroom that promotes independent learning. ESL learners' gains are
related to length of participation in programs, level of class, the
amount of inservice training taken by their instructors, class size
(about 10), and classrooms with high levels of participation, interest,
and respect, by both learners and instructors. Lead instructors spend at
least half their time on administration, although they feel their
primary role is program support. Program administrators generally feel
that learners are being well served, although specific areas were noted
as requiring attention, such as more funds to advertise and integrating
adult classes with day school programs. (KC)

This research examines the inputs, throughputs (processes), and
outputs of the Two-Way Immersion Language Program implemented in
four
elementary schools in Bakersfield City School District, the largest
K-8 school district in the State of California. Through qualitative
and quantitative methods, this study explores two models of the
Two-Way Immersion Language Program: (1) the 90/10 model, implemented
in one school since 1997, which starts kindergarten with 90% Spanish
and 10% English instruction until it gradually reaches equal time by
fifth grade, and (2) the 50/50 model, adopted by three schools in
2000, which teaches equal percentage time of English and Spanish in
all grade levels. The study used a triangular method of data
collection by (1) conducting in-depth face-to-face interviews using
structured open-ended interviewing protocols for teachers,
principals,
and district administrators, (2) collecting data from 278 students,
and (3) conducting classroom observations in the four school sites.
Findings showed that 15% of students did not continue in the
programs
across all of the schools, and the dropout rate was higher in early
grades. Findings of student achievement indicated that students in
the
two language models scored higher in mathematics than in reading on
English and Spanish standardized tests. Statistically significant
improvement in math in English standardized tests from
grade-to-grade
was found in two groups of first and fourth graders in the 50/50 and
90/10 model respectively. Further, students in both models dropped
in
their percentile ranks from grade-to-grade in English reading;
however, two groups of third and fourth graders in the 90/10 model
showed a slight improvement. Students from the two models scored
higher on Spanish than on English tests, however the improvement
varied. First and fourth graders in the 90/10 model significantly
improved in math on Spanish tests. First graders in both models
significantly improved in Spanish reading, while second and third
graders in the 90/10 model significantly dropped in their percentile
ranks in Spanish reading. These findings suggest the possible
effects
of small class size, teachers' backgrounds and attitudes,
principals'
leadership styles, teachers' actions toward parental involvement,
and
instructional support from teacher aides as significant factors that
may be related to achievement scores.

This article is a result of a small-scale study with the purpose of
investigating teacher-student verbal interactions &amp; questioning
&amp; students' curriculum-related performance in small &amp; large
mainstream classes. In mainstream classes the bilingual students
were
taught together with their monolingual Norwegian peers. The study
shows that there are inter- &amp; intragroup differences with
respect
to (1) teacher-student verbal interaction; (2) academic questioning;
&amp; (3) curriculum-related performance of students in small
classes
compared with large classes. The bilingual minority students, in
general, &amp; bilingual minority girls, in particular, benefit from
civics lessons in small classes more than they do in large classes.
It
is suggested that by creating rich possibilities for teacher-student
verbal interaction &amp; curriculum-oriented academic questioning,
small classes can provide conditions for better academic performance
in content-area subjects, eg, civics, for bilingual students in
general, &amp; bilingual girls, in particular. 7 Tables, 42

AB: Abstract
A great deal of literature on teaching English writing focuses
primarily on English dominant contexts. The particular situation of
writing instruction in non-English dominant countries has received
insufficient attention, especially in light of some of the claims
for
the role of writing coming from the &quot;center&quot; countries.
English language teachers, particularly those teaching in
non-English
dominant countries, who give substantial attention in their courses
to
teaching writing in English, face a number of challenges. This
article
discusses two main categories of challenges. In the first group are
challenges writing teachers face daily, such as class size, time
constraints, accommodating local needs, &amp; coping with problems
connected to lack of both teacher experience in teaching L2 writing
&amp; student training in L1 writing. In the second group are
challenges of a more ideological nature that are perhaps less
obvious
but more powerful &amp; far-reaching, including the need to justify
the large investment required on the part of institutions &amp;
individuals in order to teach L2 writing, the right to resist center
imposed materials &amp; methods, the need for dialogue with students
about the role of writing in their lives, &amp; the need to make L2
writing enhance learner options rather than limit them so that for
learners, writing in the L2 becomes not a pointless additional
burden
but a powerful means of accomplishing personal goals. 25 References.

Eligibility and Programming in Chapter I English as a Second Language
(E.S.L.) Programs, 1988-89. OREA Report.

Abstract
Chapter I/Pupils with Compensatory Educational Needs programs in
English as a Second Language (ESL) served students at 78 high schools in
New York City, supplementing tax-levy-funded ESL classes in those
schools serving limited-English-proficient (LEP) students. Chapter I of
the Educational Consolidation and Improvement Act funded ESL and
bilingual classes, bilingual guidance counselors, and paraprofessionals.
Three program models were provided, each for a different type of high
school, with specific formulas for allocation of funds at different
instructional levels. Evaluation was conducted through interviews, data
collection, and observation. Each participating school had diverse
problems requiring different Chapter I programs, including native
language illiteracy, increases in the number of immigrant students
unprepared for the high school curriculum, social and economic
difficulties facing new immigrant students, and large classes. In some
cases, the constant influx of new students made functional grouping
impossible, placing students at diverse ESL levels in the same class.
Recommendations for program improvement include: examining effects of
new LEP eligibility rules on demand for Chapter I funds to supplement
tax levies, evaluating effects of class size on ESL learning; and
exploring the effectiveness of the program model as it relates to
student acquisition of English language skills and time needed to
mainstream. (Author/MSE)

Anecdotal evidence leads many foreign-language teachers to conclude
there is an inverse correlation between class size &amp; student

university level, the Spanish department at Central Michigan U began
an experimental program challenging that tenuous relationship. While
most beginning 4-hour language courses meet four times a week with a
college instructor &amp; average about 25 students, the experimental
classes meet two times &amp; have 60 students. For the other 2
hours,
the 60 students are divided into groups of 15 &amp; work with
undergraduate language majors who are supervised by the large-group
instructor. The description of the program including quantitative
&amp; qualitative assessments comparing the traditional &amp;
experimental groups may serve as a model for other undergraduate
programs of similar size. 1 Table, 18 References. Adapted from the

Discussed are the problems encountered by students learning English

similar survey that asked what problems they encountered while teaching
English. Their responses were grouped into three categories:
teacher-,learner-, &amp; curriculum-based. Both students &amp; teachers
were asked to prioritize seven key issues gleaned from their initial
responses. Teachers gave large class size the highest priority, students
gave class size their lowest priority. When questioned further, a sample
of students said that class size was irrelevant if there was sufficient
motivation &amp; interest. Teachers felt that large classes increased
their workload, prevented them from catering to individual needs, &amp;
forced them to spend too much time on&quot;law &amp; order&quot;
problems. A minority of teachers felt that the appropriate pedagogy
could lead to effective learning even in the largest classrooms.

Large Classes-Exploiting the Heterogeneous Factor

Focus on English, 1993, 8, 2, Mar, 8-12

AB: Abstract
Large classes of 60-100 students are an inescapable aspect of
education in India. Studies suggest that learners in these classes
employ different strategies to accommodate their learning context.
Teachers, however, continue to use the traditional lecture method as a
means of managing the large class. In India, the heterogeneity of large
classes seems more problematic than the actual size. Large classes
contain a mix of students from regional medium schools &amp; students
from schools where English is the language of instruction, with very
diverse backgrounds &amp; language abilities. This situation is
compounded when teachers inadvertently focus on one group while ignoring
others. Researchers have begun to consider the possibility that this
heterogeneity might positively influence language learning, as students'
different abilities become a resource, rather than an obstacle for
learning. Strategies such as group work &amp; peer-consultation are
discussed. The role of teacher attitude &amp; the importance of English
instruction are emphasized. L. Taub

I did a little resrearch on class size. Yes, financial considerations do
drive administrators' decisions, but research does indicate that the
size of the class in lower grades and among minority and ESL students
helps achievement and learning.

See :

Achilles, C.M. (2003) for a report given to the NY State task force on
school and equity
Schwartz, W (2003) on Tennessee's STAR Program

presented at the Mid-South Educational Research Association

Arias, J.J & Walker, D.M. (2004) in the Journal of Economic Education
(Additional Evidence on the Realtionship Between Classs Size and Student
Performance) relationship claim that previous research showing no
effects may not have been as rigorous as they should have been and do
not account for faililng students who drop their classes, thus raising
the achievement reporting of the remaining, more successful students.
This is a study of college students

Olberg, R. (1993) Effects of ESL time and class size on the achievements
of LEP students (Research Study). Says there is a classroom efffect for
short classes (45 min), but this study did not see much gain on
standardized tests. My answer to that is the question: How different is
the standardized test from the material the students were using in the
classroom? Perhaps we need a study on transfer effects of classroom
English to real life English and the language of the tests being used.

Gilstrap, S. (2002) for a study on class size, new teachers, and 8th
grade LEP students (ratios considered were about 20:1) with classroom
coaches. (Los Angeles study of a federal program to reduce class size)

So, yes there is reseach out there that backs up the anecdotal reporting
from the classroom that says that teachers enjoy more time to work with
their students and students do better in smaller class sizes, especially
at the lower grades and with minority and second language students.

want to have classes this small as it is costly but justify it because
"reasearch says...." Sorry, can't give you the research...this is also
