Teachers,
parents, and students all say smaller classes are better, but will smaller
class sizes really lead to enhanced student performance?

Common sense suggests that smaller classes give teachers an opportunity
to devote more time to each student and enhance the learning process.
Much research supports this theory. Already, about 25 states either have
implemented or are in the process of implementing smaller class size in
their schools.
"Smaller class size enhances learning," says Don Ernst, director of
government relations with the Association
for Supervision and Curriculum Development (ASCD), "for a basic common
sense reason -- it helps teachers in getting to know the kids. You can
get to know 19 kids better than you can get to know 30 kids.
"The optimal class size where most of the research has been done, in
class sizes in grades K-3," Ernst goes on, "is 20 or fewer students."
"Advocates of smaller classes cite a host of benefits," writes Erik W.
Robelen in a new ASCD Infobrief (Issue 14, September 1998), Reducing
Class Size. "[Among those benefits are] increased student achievement,
fewer discipline referrals, more personalized attention to students, higher
teacher morale, and more time for teachers to focus on instruction rather
than on classroom management…"
Yet skeptics are concerned that reducing class size will increase costs
-- which it almost certainly will -- without substantially increasing
teacher effectiveness or that other, less expensive approaches might achieve
the same educational goals without costing as much as limiting class size.
"If you have a choice between a small class with a bad teacher or a
large class with a good teacher, which would you choose?" is the rhetorical
question from University of Rochester economist Eric Hanushek.
"Reducing Class Size," the ASCD Infobrief, summarizes the questions
policymakers must confront in making decisions about class size:
"Given funding limitations, is reducing class size the best method
to improve education?
"What approaches to class-size reduction are likely to prove most
effective? What factors might enhance the effectiveness of smaller classes?
"How can policymakers handle some of the challenges of lowering class
size, such as ensuring a qualified teacher pool and managing classroom
space shortages?
"What impact does class-size reduction policy have on equity in education?"
Examining the available research will help guide educators who are
considering a reduction in class size in their classrooms.

The Debate Over Class
Size
Plenty of research supports the initiative to reduce class
size. Early results from a class size reduction program introduced
in California also seems to support the plan. This two-part
article examines both sides of the issue.
Class Size Reduction:
Success Stories Noted in Report
A U.S. Department of Education report, "Local Success Stories:
Reducing Class Size," describes challenges and opportunities
in efforts to reduce class size. Included: Recent research
on class size reduction.
A wide-ranging study on the effects of class size is Tennessee's Project
STAR (Student-Teacher Achievement Ratio), along with two associated data
collections. STAR was a longitudinal study of first, second, and third
grade classrooms in Tennessee. STAR was unusual, according to the Department
of Education's report Reducing Class Size: What Do We Know?, because
of its:
Study size. Project STAR included 79 schools, more than 300
classrooms, and 7,000 students, with students being followed through
4 years of experience in the given class size.
Random assignment. Teachers and students were randomly assigned
to three different kinds of classes in order to ensure that the study
was not biased by who was in which type of class. The three categories
of classrooms were classes with 13-17 students; classes with 22-26 students
with no instructional aide; and classes with 22-26 students with an
instructional aide.
In-school design. All participating schools implemented at
least one of each of the three types of classes in order to cancel out
the possible influences coming from variations in the quality of the
participating schools that might affect the quality of the classroom
activity.
The students in the smaller classes, according to the student testing
in STAR, performed better than the students in the larger classes did.
This was the case for white and minority students in smaller classes,
and for smaller class students from inner-city, urban, suburban, and rural
schools.
In fourth grade, students from smaller classes still performed better
than the students from larger classes did. "At least through eighth grade,
a decreasing but significant higher academic achievement level for the
students from the smaller classes persists," according to the Department
of Education report.
PROBLEMS WITH SMALLER CLASSES
The most clear-cut problem with reducing class size is the cost. Significantly
more must be spent on added teachers and added space to limit class size.
In addition, while some states have reduced class size and then done research
to make sure that doing so actually enhances student performance, others
have not spent money on this kind of research, so they don't know what
the added cost is buying.
At times reducing class size has resulted in large numbers of new teachers
being thrust into tough situations. Critics then question the educational
outcome and quality of education provided.
In 1996, California had to hire many new teachers to implement a reduction
in class size mandated by the governor. Many of the new teachers worked
with emergency credentials. Those teachers taught smaller classes, but
often had few or no experienced teachers to turn to for advice.
TEACHERS' VIEWPOINT
Despite some problems with cutting class size, teachers generally support
the smaller class sizes.
Shari Elmer, who teaches kindergarten at Loyola Elementary School in
Los Altos, California, says in the September 1998 Instructor magazine
that the new 20-student-cap has made a huge difference in her classroom.
"The extra time got me inspired to try new things -- things I could
never have done before," Elmer said. "I played word games with students.
I used hand puppets. I never got the chance or had the time to do those
kinds of things before."
"Ask any teacher, we all prefer smaller classes," Association of Texas
Professional Educators President Amy White says.
Due to an expected $6 billion state budget surplus, Texas has a plan
to enforce a 22-student per class limit in kindergarten through fourth
grade.
The debate over class-size and instructional quality will continue.
But, as cited in the Department of Education report Reducing Class
Size: What Do We Know?, "Students, teachers, and parents all report
positive effects from the impact of class size reductions on the quality
of classroom activity."

Tapping
the Benefits of Smaller Classes
After decades of research on class size, the evidence is considerable
and compelling: Especially in the early grades, smaller classes do make
a difference.
Class
Size
While many education reform proposals remain controversial, reducing class
size to allow for more individualized attention for students is strongly
supported by parents, teachers and education researchers. This NEA position
paper includes links to research summaries.
