BLOOMINGTON, Ill.— Shinnosuke (Shin) Sawada gingerly flips the clasps of a thin wooden
box and unfolds a floral-print cloth, uncovering a rectangular object that he places
on the table in front of him. Possessing a delicate beauty that belies its usefulness,
the abacus, Sawada explained, has been used for thousands of years in his native Japan
and elsewhere throughout the world to perform quick mental calculations — helping
people from merchants to students in their daily lives. Yet the abacus has never caught
on as a learning tool in the United States. Relegated to the waiting rooms of doctor’s
offices or left to gather dust in a basement, the abacus is seen as a mere plaything.
Sawada is aiming to change that perception in the Bloomington-Normal area.
An exchange student from Toyko’s Keio University majoring in economics and sociology
at Illinois Wesleyan University, Sawada was perplexed by Americans’ lack of interest
in the abacus. Called a soroban in Japanese, the abacus has been used since the 14th century and is still widely
taught in Japanese primary schools — primarily as an aid to faster mental calculation.
Using the visual imagery of a soroban, students can arrive at the answer to a problem
at the same time, or even faster, than using an electronic calculator.
Once Sawada takes on a mental calculation himself, it becomes apparent that this fact
is no exaggeration. The playful rolling of the abacus with his hand guiding it along
as a skateboard vanishes. Problem number one is 7,263 divided by 415. Three seconds
later, Sawada declares “17.501,” with an air of such certainty that a glance at a
calculator is hardly necessary to verify his answer. His fingers move over the abacus
so quickly it’s difficult to imagine that a calculation is taking place in his mind.
When questioned if his prodigious math ability is a natural or learned trait, Sawada
hesitates. “A little bit between the both,” he answers with humility, although he
demurely adds that he was the National Abacus Champion in Japan at the age of 12.
In his first semester at Illinois Wesleyan, Sawada found a way to bring greater appreciation
for the abacus to Bloomington-Normal through the Action Research Seminar. This course
focuses on bettering the Bloomington-Normal community through innovative student-led
projects. Deborah Halperin, director of the Action Research Seminar, asks students
to create a community outreach project. Sawada focused on the abacus, and began by
teaching other students in the seminar how to use one. Tia Patsavas ’16, one of Sawada’s
seminar classmates, points out that even though she had never used an abacus, Sawada
made it easy for her to understand. This success in class encouraged him to take the
leap from teaching university students to teaching children in the community.
Sawada didn’t just teach youngsters how to use the abacus — he also taught them how
to build them. With help from Illinois Wesleyan students, Boys and Girls Club members,
and volunteers from the local Tool Library (an organization at which Sawada has also
volunteered), Sawada constructed simple wooden abacuses at the Children’s Discovery
Museum in Normal. In total, the group assembled about 32 of the handmade “calculators.”
The same day, Sawada taught the children how to use the their new tools. “Nobody knew
how to use the abacus,” he said. “I’m glad that they can calculate on their own by
using them. They were also excited to make an abacus and to use it on their own.”
Sawada is clearly comfortable in the role of teacher. Cheerful and with a smile that
rarely leaves his face, Sawada has the ability to patiently explain the ins-and-outs
of the abacus in a manner that even a novice would understand as he slowly moves the
abacus beads up and down, occasionally referring to his self-created diagrams to clear
up any confusion. His teaching experiences began after high school, when he volunteered
this past summer with Teach for Japan. Mentoring and tutoring students from low-income
areas of Tokyo, Sawada’s interest was piqued by the disparities in education levels
between Japan’s affluent students and their less wealthy counterparts. Economists
have dubbed this problem in Japan the “education gap.”
The experience also sparked an interest in education issues related to labor and community
development. A big attraction for Sawada to study at Illinois Wesleyan was the Action
Research Center, its focus on community development and a student’s ability to work
on original projects. In ways that surprise even him, the abacus has become a tool
that has connected him deeply to the Bloomington-Normal community. He feels real joy
when seeing a younger person learn the power of this ancient tool.
Even though his coursework with the Action Research Center is complete, Sawada plans
to continue to teach the abacus through the Boys and Girls Club. “I’m excited when
the children are excited to use the abacus on their own,” he said. “It makes me feel
good when they can begin to calculate on their own using it.” He hopes one day to
combine his interests in economics and sociology to conduct in-depth investigations
comparing community development in the U.S. with that in Japan.
Long term, Sawada has set his sights on bringing the abacus to an even broader audience.
“My dream is that the abacus will be adapted in U.S. elementary education just as
it is in the Japanese system.”
