Calculators May Be the Wrong Answer
As a 'Digital Divide' Widens in Schools
By DANIEL GOLDEN
Staff Reporter of
THE
WALL STREET JOURNAL
LOUISVILLE, Ky. Rick Martin's fifth graders get flummoxed
subtracting two-digit numbers. Hardly any know their multiplication
tables.
But in his class, they don't have to.
"Go ahead and get your calculators out," the teacher tells
his students at Hazelwood Elementary School one morning. Then, he assigns
this problem: The Voyager 2 satellite was launched in August 1977 and
reached Neptune in August 1989. How many months did the journey take?
Mr. Martin's 24 students – 11 are black and 17 live in a nearby
public-housing project – start punching numbers on calculators
that the school bought for them. But most flounder, not understanding that
they have to subtract 1977 from 1989 and then multiply the difference by
12. Several students shout wrong answers before 11 year-old Rodney Murphy
provides the correct one: 144.
Mr. Martin flicks on the overhead projector for some review work. But
what he illuminates on the screen isn't a multiplication table. It's a
special transparent calculator for teaching. "Let's do this one
together," he says.
A digital divide has appeared in U.S. elementary schools, but it's the
reverse of what you might think.
There is widespread concern about a lack of computers for poor minority
students and a widening racial gap in math achievement. But low-income and
minority elementary school students are actually more likely to use one
form of technology than their better-off, white counterparts: the
calculator.
Affordable Machines
Unlike computers, calculators are so inexpensive that any school can
afford them. Elementary schools typically buy their calculators for
roughly $5 each from wholesale distributors for Texas Instruments Inc. and
smaller manufacturers. In states such as Kentucky, which let students use
calculators on standardized tests, some struggling schools aim to raise
scores by emphasizing calculator-based instruction.
Teachers like Mr. Martin favor calculators as motivational tools. These
instructors hope the machines will boost the confidence of students whose
computational skills are shaky and help introduce them to concepts such as
time and distance.
But more calculator use in inner-city schools generally hasn't added up
to higher test scores. The majority of experts on elementary-school
learning maintain that, for students who lack basic number proficiency,
calculators may provide only the illusion of progress. "Kids get to
use calculators as a substitute for practice, and they never really
understand arithmetic," says Sandra Stotsky, deputy education
commissioner in Massachusetts, a state that has taken a back-to-basics
approach.
An increasing number of teachers in harried urban schools take a
different view. "For at-risk children, a calculator is a valuable
tool" that can boost self-esteem and stir curiosity, says Brenda
Stokes, a third-grade teacher at Hazelwood Elementary.
Stirring Controversy
Regular calculator use in elementary school has stirred controversy
since the 1980s. Calculator manufacturers and certain education groups
have pushed the idea. Suburban parents in some areas have rallied against
it.
But now, evidence of a calculator divergence based on race and wealth
suggests that technology may sometimes reinforce inequities in scholastic
achievement, rather than narrow them.
The Brookings Institution, a Washington, D.C., think tank, issued a
study in September that found that half of black fourth graders nationwide
and 44% of Hispanics use calculators every day, compared to only 27% of
whites. Analyzing data from the National Assessment of Educational
Progress, a federal standardized exam, Brookings found that the every-day
calculator users scored lower than less-frequent users, both overall and
within each racial group. Students are allowed to use calculators on the
test.
"This raises a troubling new perspective on the 'digital divide'
that deserves serious attention," Brookings concluded.
The think tank limited its analysis to race. But the same test data
indicate that poor students and those whose parents have relatively little
education also are more likely to use calculators more frequently. Among
fourth graders qualifying for government-subsidized lunches, 45% reported
using calculators every day in class, compared to 29% of students from
better-off families. Among children who reported that their parents didn't
finish high school, 42% said they use calculators every day, compared to
28% of children of college graduates. Public-school students were more
than twice as likely to use calculators every day in class as those
attending private school.
Roughly similar patterns exist here in Kentucky, where an
elementary-school student who is black and poor is more likely than a
wealthier white student to be encouraged to use a calculator, rather than
figure out problems mentally or with pencil and paper. On a survey that
accompanied a statewide math test in April, 43% of fifth graders in
Jefferson County, which includes Louisville, reported using calculators
almost every day in math class. The statewide figure was only 33%.
Jefferson County schools are 30% black, compared to 10% statewide.
At Hazelwood Elementary, where nearly half of the students are black
and almost all qualify for subsidized school lunches, 76% of fifth graders
said on the statewide survey that they use calculators almost every day.
By contrast, at Greathouse/Shryock, a suburban Louisville school with a
predominantly white, upper-middle class student body, only 16% of fifth
graders said they use calculators so frequently.
On the statewide math test, which allows students to use calculators,
fifth graders at Greathouse scored an average of 104, exceeding the
"proficiency" level of 100, on a scale of 0 to 140. The
statewide average was 67. Hazelwood fifth graders scored only 40.
The Chicago Fiasco
Initially, some urban teachers were wary of calculators. When Chicago
in 1988 became the first large city to buy them for all students in grades
four through eight, the experiment turned into a fiasco. Teachers didn't
receive adequate training on how to use the devices in class. Calculators
remained in their boxes and were stolen by the hundreds.
But with a nudge from manufacturers and some major education groups,
inner-city teachers have embraced calculators. Texas Instruments, which
makes 80% of the calculators used in U.S. schools, has promoted its
product with textbook publishers and teachers of all grades. The company
this year gave nearly $500,000 to the National Council of Teachers of
Mathematics for the professional group's training academy, and has
occasionally paid for bringing teachers from abroad to speak at the
council's conferences.
In 1989, the influential math-teachers organization had said it found
"no evidence to suggest that the availability of calculators makes
students dependent on them" and urged their use starting in
kindergarten. This year, before it received the Texas Instruments
donation, the group revised its guidelines to extend the endorsement of
calculators to pre-kindergarten.
Texas Instruments, based in Dallas, gives calculators to textbook
publishers and authors for testing, and the company produces its own
classroom texts. Ms. Stokes, the third-grade Hazelwood teacher,
supplements her Houghton-Mifflin textbook, which calls for moderate
calculator use, with games and exercises provided by Texas Instruments.
Thomas Ferrio, a Texas Instruments vice president, says he doesn't know
whether it sells more calculators per student to urban districts, because
it doesn't track sales that way. He does assert that calculators can spur
low-achieving students to acquire basic skills. "I see teachers using
the technology as a motivational tool for students to keep them
interested," he explains.
Hazelwood Elementary's Mr. Martin, who once dressed up as Julius Caesar
for a history lesson, says calculators can "broaden [students']
horizons." But some of his fifth-graders seem overly dependent on the
devices.
Asked to subtract 27 from 35 without electronic aid, 10_year_old
Tarrell Holstein takes a pass. "Oh, man, I hate subtraction," he
says.
Invited to multiply nine times six the old-fashioned way, Steven
Coleman shakes his head. "I can't do it mentally," the 11
year-old says.
At Shelby Elementary School in Louisville, which like Hazelwood is
about half black and mostly poor, students traditionally had to share
calculators. Then, last year, the Kentucky state accountants' board
donated calculators left over from its state licensing exam, so that every
Shelby student could have one. The proportion of fifth graders using
calculators almost every day in math class soared to 53% this spring, from
33% a year earlier. But fifth-grade math scores on the statewide test
dropped to 48, from 49.
Is it 'Cheating'?
Kristen Spetz, a Shelby fifth-grade teacher, used to drill her students
on multiplication facts for most of the year. Now she's a calculator
convert. Memorization "was stressing these kids out," she says.
"They couldn't get past it. Now we hit multiplication, we practice
our tables, and we move on. The calculator takes away a lot of
stress."
"A lot of kids think it's cheating," the teacher says. But
she assures them: "It isn't [cheating] if it helps you."
Some fifth graders in Louisville seem to lack the numbers sense to
employ calculators effectively. One morning, Ms. Spetz assigns the
following problem: One student is paid $5 a day to clean the hallways.
Another student is paid only one cent the first day, but his wages double
on each succeeding day. After 21 days, which student has made more money?
The 29 fifth graders set to work with their calculators. While most of
them correctly figure that the first student would earn $105, all of them
understate the second student's income ($10,485.76 on the 21st day alone).
Their error isn't computational but conceptual. They don't know what
doubling means. Instead of continually multiplying by two, they add by
twos, or ones.
Calculator-Free Classes
Engelhard Elementary in downtown Louisville has found a different
solution to math woes. At the school, where half of the students are black
and 80% are low-income, only 14% of fifth graders in April reported using
calculators almost every day. Yet Engelhard's fifth-grade math score rose
to an average of 60, from 56, an improvement that helped earn the school
extra state funding.
Engelhard benefits from the involvement of volunteers from local
colleges, but it also emphasizes mental math. Every Monday, these student
teachers lead calculator-free math lessons for fourth and fifth graders,
concentrating on strategies for memorizing multiplication tables.
Surveys in other states indicate varying degrees of racial and economic
gaps in calculator use. In Pennsylvania, for example, only 5% of fifth
graders taking the statewide math test in February and March reported
using a calculator almost every day for math class or homework. But for
black fifth graders, the figure was 9%, compared to 8.6% for Hispanics,
4.4% of white students and 4.1% of Asians.
Maine, a state whose population is 98% white, also has asked students
about calculator use. Of fourth graders who reported using calculators
almost every day, 47% didn't meet state math standards on a test in March,
on which they were allowed to use calculators. In contrast, of students
using calculators two or three times a month, only 23% fell below
standards. Maine officials declined to provide data on the race and
economic status of its calculator users.
Many educational authorities agree that occasional calculator use is
appropriate in elementary school – to check answers, for instance, or
add long columns of numbers for a science project. By high-school algebra
and calculus classes, students of every race and income level depend on
more-sophisticated graphing calculators, which have replaced the slide
rule and are permitted on the SAT college-entrance exam.
At least one school in Louisville credits calculators for boosting test
scores. When Michael Suttles took over last year as principal of
inner-city Atkinson Elementary, he pushed teachers to incorporate
calculators in their lessons. The proportion of fifth graders who reported
using calculators almost every day nearly doubled, to 51%, by this April.
And the school's average test score rose two points, to 41, although it
remains among Kentucky's lowest.
Influential Endorsements
Educators have debated the proper role of calculators in elementary
school for two decades, but by the early 1990s, Kentucky and some other
states had taken action to encourage use of the devices in class and on
standardized tests. This move was strongly supported by the 1989
endorsement of the National Council of Teachers of Mathematics and a
similarly enthusiastic statement in 1990 by the National Research Council,
a quasi-public organization that advises the government and scientific
community on policy issues. At the same time, the National Science
Foundation, a federal grant-giving agency, began pouring millions of
dollars into concept-oriented, calculator-friendly curricula.
Asked about the Brookings Institution's new findings about the racial
disparity in calculator use and the indication that calculator dependency
may hurt test performance, Lee V. Stiff, president of the math-teachers
council, questions the validity of the sort of student survey relied upon
in the Brookings study.
Mr. Stiff contends that more than 100 studies __ based on testing
students with and without calculators, as well as classroom observation __
show that calculators can improve student achievement, problem-solving,
and understanding of mathematical ideas. He adds that when award-winning
teachers are surveyed, they overwhelmingly favor use of calculators in
elementary grades. However, Tom Loveless, who wrote the Brookings report,
says that most of the pro-calculator studies were poorly designed, lasted
only a few weeks, and lacked adequate controls.
John S. Bradley, a program manager with the National Science
Foundation, maintains that calculators generally improve student scores,
although he adds that they shouldn't be allowed to become a crutch.
"People worry now that kids are going to use calculators instead of
learning basic number facts," Mr. Bradley says. "We used to
worry they would count on their fingers and not learn basic number
facts."
The move by states in the early 1990s to promote calculator use quickly
provoked a backlash led by university math professors and suburban
middle-class parents. In response, some states, such as California,
adopted a back-to-basics approach and discouraged calculator use prior to
sixth grade. Kansas recently expelled calculators from its fourth-grade
math test.
The anti-calculator reaction has largely bypassed larger cities,
however. Under pressure from suburban parents, the Massachusetts
Department of Education now emphasizes basic math skills. It prohibits
calculator use on its fourth-grade and sixth-grade math tests. But the
city of Boston recently adopted a curriculum backed by the National
Science Foundation that encourages fourth graders to use calculators.
Some of Mr. Martin's charges at the Hazelwood school say they even take
their calculators shopping. Jamisha Thomas, 10, says she likes to buy
potato chips for 50 cents and popsicles for $1.25. Asked for the sum, she
enters the numbers in her calculator – but forgets a decimal point.
"Fifty-one dollars and 25 cents," she says.
