Four-Day School Week Can Improve Academic Performance, Policy Study Finds Shortening the school week to four days has a positive impact on elementary school students' academic performance in mathematics, according to researchers at Georgia State University and Montana State University. The study, published in the journal Education, Finance and Policy in July, analyzed the impact of a four-day school week on student achievement by comparing fourth-grade reading and fifth-grade math test scores from the Colorado Student Assessment Program (CSAP) for students who participated in a four-day school week, versus those who attended a traditional five-day school week. The researchers found a four-day school week had a statistically significant impact on math scores for fifth-grade students, while reading scores were not affected.

**2015 Brain scans better forecast math learning in kids than do
skill tests**. Gray matter volume and connections between several brain regions better
forecast 8-year-olds' acquisition of math skills than their performance on standard math tests.

Surprising results The scientists were surprised by the extent and nature of the connections between brain
regions that predicted the development of the children's math skills. Greater volume and connectivity of
two
areas forecast skill development: the ventro-temporal occipital cortex, which is a brain region that
supports visual object perception, and the intra-parietal sulcus, which helps people compare and make
judgements about numbers, such as understanding that four is more than three. The strength of these
regions'
interconnections with the prefrontal cortex was also predictive. The work identifies a network of brain
areas that provides a scaffold for long-term math skill development in children, Menon said.

Reform Math / Fuzzy Math

**Reform math** says kids should explore and understand concepts like place
value
before they become fluent in the standard way of doing arithmetic. Critics say it fails to stress basic
computational skills, leaving students unprepared for higher math. Stanford University mathematician James
Milgram calls the reform math-inspired standards a "complete mess" - too advanced for younger
students, not nearly rigorous enough in the upper grades. And teachers, he contends, are largely
ill-prepared to put the standards into practice. "You are asking teachers to teach something that is
incredibly complicated to kids who aren't ready for it," said Milgram, who voted against the
standards
as part of the committee that reviewed them. "If you don't think craziness will result, then you're
being fundamentally naive."

**Long Division Style**

**44 States have started using the Common Core** learning standards, which has made math -
adding, subtracting, multiplying and dividing become as complicated as calculus. The standards for
elementary math emphasize that kids should not only be able to solve arithmetic problems using the
tried-and-true methods their parents learned, but understand how numbers relate to each other. Everyone is
stumped by unfamiliar terms like "rectangular array" and "area model." They wrestle
with
division that requires the use of squares, slashes and dots. They rage over impenetrable word
problems.

Simple arithmetic isn't so simple anymore, leading to plenty of angst at home. Even celebrities aren't

Poor "Gut Sense" Of Numbers Contributes To Persistent Math Difficulties

Journal *Child Development
http://www.medicalnewstoday.com/releases/228812.php*

Having a poor "gut sense" of numbers can lead to a mathematical learning disability and difficulty in achieving basic math proficiency. This inaccurate number sense is just one cause of math learning disabilities, according to the research led by Dr. Michele Mazzocco of the Kennedy Krieger Institute. Heightened interest in the nature and origins of these learning difficulties has led to studies to define mathematical learning disability (MLD), identify its underlying core deficits, and differentiate children with MLD from their mathematically successful counterparts. The study findings suggest that an innate ability to approximate numbers, an intact ability present in human infants and many other species, contributes to more sophisticated math abilities later in life, while a less accurate ability underlies MLD. Additionally, the findings reveal that a poor number sense is not the only potential source of math difficulties, reinforcing that a 'one size fits all' educational approach may not be the best for helping children who struggle with math.

"Some children have a remarkably imprecise intuitive sense of numbers, and we believe these children have math learning disability, at least in part, due to deficits in this intuitive type of number sense," said Dr. Mazzocco, Director of the Math Skills Development Project at Kennedy Krieger. "But other students who underperform in math do so despite having an intact number sense. This demonstrates the complexity of determining precisely what influences or interferes with a child's mathematical learning. Difficulty learning math may result from a weak number sense but it may also result from a wide range of other factors such as spatial reasoning or working memory.

**Finding Math Hard? Blame Your Right Parietal Lobe**

Source: University College London

sciencedaily.com/

Scientists have, for the first time, induced difficulties with mathematics (dyscalculia) in subjects who
normally find math easy. The study, which finds that the right parietal lobe is responsible for
dyscalculia,
potentially has implications for diagnosis and management through remedial teaching.

Dyscalculia is just as prevalent in the population as dyslexia and attention deficit hyperactivity
disorder
-- around 5% of the population is affected. However, dyscalculia has not been given the same attention as
other disorders and the underlying brain dysfunction causing dyscalculia is still a mystery. It is hoped
that this study will provide a better understanding of the condition and lead to better diagnosis and
treatment.

Dr Roi Cohen Kadosh, of the UCL Institute of Cognitive Neuroscience, said: "This is the first causal
demonstration that the parietal lobe is the key to understanding developmental dyscalculia. Most people
process numbers very easily -- almost automatically -- but people with dyscalculia do not. We wanted to
find
out what would happen when the areas relevant to maths learning in the right parietal lobes were
effectively
knocked out for several hundred milliseconds. We found that stimulation to this brain region during a
maths
test radically impacted on the subjects' reaction time.

"This provides strong evidence that dyscalculia is caused by malformations in the right parietal lobe
and provides sold grounds for further study on the physical abnormalities present in dyscalculics'
brains. It's an important step to the ultimate goal of early diagnosis through analysis of neural
tissue, which in turn will lead to earlier treatments and more effective remedial teaching."

## Avoidance Strategies in Mathematics

### STUDENTS MAY BE LEARNING MORE ABOUT AVOIDANCE STRATEGIES THAN ARITHMETIC IN MATH CLASS; STUDY SHOWS WHAT TEACHERS CAN DO

WASHINGTON - "Please don't call on me" can be a pervasive thought by students who are not
doing well in math class. By early adolescence, it is common for some students to become experts in
avoidance strategies -- avoiding asking for help when they need it, withdrawing effort and resisting novel
approaches to learning -- in order to deflect attention from low ability. This type of behavior can cause
students to fall further behind academically and may\ eventually lead some to drop out of school. But new
research shows that teachers that emphasize learning rather than performance may help prevent this
self-destructive behavior. The findings appear in the current issue of the Journal of Educational
Psychology, published by the American Psychological Association (APA).

In their study involving 1,092 sixth-grade students in 65 sixth-grade classrooms in four ethnically and
economically diverse school districts in three Midwestern states, Julianne C. Turner, Ph.D. of the
University of Notre Dame and co-authors surveyed the students to determine use of avoidance strategies.
The
study also included the use of trained observers who watched and audiotaped nine of the students'
teachers while they taught their math classes.

The researchers found that students reported using fewer avoidance techniquesin classrooms perceived as
emphasizing learning, understanding, effort and enjoyment. In those classrooms, teachers helped students
who
had problems understanding, gave them opportunities to demonstrate new competencies and provided
substantial
motivational support for learning. Teachers in these "mastery-oriented" classrooms made sure
their
students did not feel inadequate or ashamed when they did not understand. "By modeling their own
thinking processes, these teachers demonstrated that being unsure, learning from mistakes, and asking
questions were natural and necessary parts of learning," according to the authors. By contrast,
"students reported higher incidences of avoidance strategies in classrooms in which teachers devoted
little attention to helping students build understanding and in which motivational support was
low."

**The teacher observations, say the authors, provided valuable insight into how teaching methods
affect avoidance behaviors.** For instance, in a classroom where students used more avoidance
strategies, the teacher placed greater emphasis on getting an answer correct, with little discussion about
the important concepts in a lesson and little explanation of why an answer was correct. If a student did
not
know the answer, the teacher would ask another student and did not usually stop to explain the answer.
"Because the teacher typically did not respond to mistakes and misunderstandings with explanations or
allow students to explain their strategies, his students may have felt vulnerable to public displays of
incompetence and adopted more avoidance strategies," explained the researchers.

**In classrooms where students used fewer avoidance strategies, the teachers tended to model, hint
and
elicit support from other students to help their students learn.** In those classrooms, the
students were active participants in instructional discourse that stressed understanding and explanation.
"Perhaps because they knew their teachers and peers would help, students in these classrooms did not
seem to need to adopt avoidance strategies to appear able to others," said the authors.

Classrooms with students who reported using avoidance strategies less also had teachers that used
math-related humor as part of their lessons. Humor may lessen tension and encourage students to view their
math classes as more enjoyable, say the authors.

**As Math Scores Lag, a New Push for the Basics**

SEATTLE For the second time in a generation, education officials are rethinking the teaching of math in
American schools.

The changes are being driven by students lagging performance on international tests and mathematicians
warnings that more than a decade of so-called reform math critics call it fuzzy math has crippled students
with its de-emphasizing of basic drills and memorization in favor of allowing children to find their own
ways to solve problems. At the same time, parental unease has prompted ever more families to pay for
tutoring, even for young children. Shalimar Backman, who put pressure on officials here by starting a
parents group called Wheres the Math?, remembers the moment she became concerned. When my oldest child, an
A-plus stellar student, was in sixth grade, I realized he had no idea, no idea at all, how to do long
division, Ms. Backman said, so I went to school and talked to the teacher, who said, We dont teach long
division; it stifles their creativity.

Across the nation, the reconsideration of what should be taught and how has been accelerated by a report
in
September by the National Council of Teachers of Mathematics, the nations leading group of math teachers.
It
was a report from this same group in 1989 that influenced a generation of teachers to let children explore
their own solutions to problems, write and draw pictures about math, and use tools like the calculator at
the same time they learn algorithms. But this fall, the group changed course, recommending a tighter focus
on basic math skills and an end to mile wide, inch deep state standards that force schools to teach dozens
of math topics in each grade. In fourth grade, for example, the report recommends that thecurriculum
should
center on the quick recall of multiplication and division, the area of two-dimensional shapes and an
understanding of decimals.

The Bush administration, too, has created a panel to study research on teaching math. It is expected to
issue recommendations early next year. Here in Washington, Gov. Chris Gregoire has asked the State Board
of
Education to develop new math standards by the end of next year to bring teaching in line with
international
competition, and a year later to choose no more than three curriculums to replace the dozens of teaching
methods now in use. Ms. Gregoire, a Democrat, also wants new math requirements for high school graduation.
In Utah and Florida, too, state education officials are re-examining their math standards and curriculum.
Grass-roots groups in many cities are agitating for a return to basics. Many point to Californias
standards
as a good model: the state adopted reform math in the early 1990s but largely rejected it near the end of
the decade, a turnaround that led to rising math achievement.

The Seattle level of concern about math may be unusual, but theres now an enormous amount of discomfort
about fuzzy math on the East Coast, in Maine, Massachusetts and Pennsylvania, and now New Jersey is
starting
to make noise, said R. James Milgram, a math professor at Stanford University. Theres increasing
understanding that the math situation in the United States is a complete disaster.

Schools in New York City use a reform math curriculum, Everyday Mathematics, but some parents there, too,
would like to see that changed, a step they are advocating through NYC HOLD, a group of parents and
teachers
that has a Web site with links to information on math battles nationwide.

A spokesman for the New York City Department of Education said that Everyday Mathematics covered both
reform
and traditional approaches, emphasizing knowledge of basic algorithms along with conceptual understanding.
He added that research gathered recently by the federal Department of Education had found the program to
be
one of the few in the country for which there was evidence of positive effects on student math
achievement.

**The frenzy has been prompted in part by the growing awareness that, at a time of increasing
globalization, the math skills of children in the United States simply do not measure up:**
American eighth-graders lag far behind those from Singapore, South Korea, Hong Kong, Taiwan, Japan and
elsewhere on the Trends in International Mathematics and Science Study, an international test.

Parental discontent here in Washington State intensified after the announcement in September that only 51
percent of 10th graders passed the math part of state assessment tests, far fewer than showed proficiency
in
reading or writing. Math is on absolutely everybodys radar in the state right now, said Ms. Backman, whose
Wheres the Math? group drew hundreds of parents and math teachers last month to a forum on K-12 math. Many
parents and teachers remain committed to the goals of reform math, having children understand what they
are
doing rather than simply memorizing and parroting answers. Traditional math instruction did not work for
most students, say reform math proponents like Virginia Warfield, a professor at the University of
Washington. It produces people who hate math, who can't connect the math they are doing with anything
in
their lives, Dr. Warfield said. Thats why we have so many parents who see their children having trouble
with
math and say Honey, dont worry. I never could do math either.

**In Asian cultures, she added, the assumption is that everyone learns mathematics, and of course,
parents will help with mathematics**.

But even many of those who admire the goals of reform math want their children to have more drills. My
mother is a high school math tutor, and her joke is that this math is whats kept her in business, said
Marcy
Berejka, who each week brings Ben, 8, and Dana, 6, to Kumon, a tutoring center based in Japan that has
more
than a dozen franchises in the Seattle area. Theres a lot thats good in the new curriculum, but if you
don't memorize the basic math facts, it gets harder as math gets more complicated.

The states superintendent of public instruction, Terry Bergeson, a supporter of reform math, said in an
interview: I came through the reading wars years ago, and now were right in the middle of that with
mathematics. It comes back to balance. Of course you need to know your math facts, but you also have to
understand what youre doing. **The whole country has been in denial about mathematics, and now were
sort of at a second Sputnik moment.**

In part, the math wars have grown out of a struggle between professional mathematicians, who say too many
American students never master basic math skills, and math educators, who say children who construct their
own problem-solving strategies retain their math skills better than those who just memorize the algorithm
that produces the correct answer. After Dr. Milgram of Stanford appeared at a Wheres the Math? meeting,
Dr.
Warfield, an expert on teaching math educators, wrote in a newsletter that when Dr. Milgram told parents
to
fight for change, it was implicit in the instructions that mathematicians who do not agree are classified
as
mathematics educators (a rung or two below the night custodian). The battle here has left many parents
frustrated, confused and not sure if they should trust their childrens schools to give them the skills
they
need. Many have already voted with their feet, enrolling their children in math tutoring. State
Representative Glenn Anderson, a Republican member of the House education committee who has fought for a
more rigorous curriculum, said state data showed that Washington residents spent $149 million on tutoring
and other education support services in 2004, more than three times the $44 million they spent 10 years
earlier. Kumon, which has a global clientele of more than four million children in 43 countries, focuses
on
drilling children on basics. Students work their way through hundreds of assignments that move in
incremental steps from tracing numerals all the way through differential calculus.

Every week for five years, Tove Burrows has brought her son, Petter, 13, to the Kumon Center in Mercer
Island to turn in the worksheets he has done at home, sit down to new drills and pick up a set of
assignments for the week ahead.

If the math curriculum in the schools were different, I would not be doing Kumon, said Ms. Burrows, whose
son is an A student at Islander Middle School. But I want to make sure hes mastered the basics, and in
school they dont spend enough time on basics to get that mastery. On Mercer Island, an affluent suburb of
Seattle that had the states best scores on the 10th-grade test, the pendulum has begun to swing toward
emphasizing computational skills, especially in high school. Were looking at texts that have more numbers
and less language, said Lisa Eggers, president of the Mercer Island School Board, who at one point sent
two
of her three children to Kumon. And were one of the few districts where the math scores are going
up.

Even so, seeking outside math help is common in the district, with almost 100 students leaving the high
school for math and going instead to nearby private academies for one-on-one tutoring, for which the
school
give will give them credit.

John Harrison, principal of Mercer Island High School, estimates that as many as 10 percent of his schools
1,400 students are getting outside math help. Its not surprising that math is so important in Seattle,
with
so many people earning their living at Microsoft or Boeing, Mr. Harrison said. Our kids do very well on
the
state tests, compared to the state averages, but even here, math proficiency is less than reading and
writing.

Teaching Math as Narrative Drama

October 3, 2010 By Katherine Mangan Waco, Tex.

When Edward B. Burger presents a math challenge to his class at Baylor University, he paces the aisles and
pairs students together. "I want to hear chattering," he says. Before long, students are
laughing
and shouting out answers. He dashes to the chalkboard to scribble them down, creating long rows of numbers
topped with running stick figures. Mr. Burger, 46, who is visiting from Williams College, keeps up a
rapid-fire banter with his students, whom he calls by name.

He is here this semester as a recipient of Baylor's annual Robert Foster Cherry Award for Great
Teaching, which came with $215,000 in cash and $35,000 for Williams's math department. The 12-member
committee that culled more than 100 nominations from around the country was impressed with his string of
teaching awards, his multimedia textbooks and videos for secondary schools, and his televised analysis of
the math behind the 2010 Winter Olympics.

Mr. Burger was younger than the students he's teaching at Baylor when he discovered how much fun
teaching math could be. Armed with a lesson plan and a conviction that he could cut through his
classmates' collective fog, he asked his high-school teacher if she'd step aside and let him teach
two classes. "She agreed, and at the age of 17, I stood up in front of a precalculus class of about
40
students who looked at me like I was the biggest nerd in the world," says Mr. Burger.

He earned a doctorate from the University of Texas at Austin and began teaching night classes at Austin
Community College at age 22. "What I was trying to do was to take really complex, intricate, abstract
ideas of mathematics and make them come to life for these students," he says. He began encouraging
students to be creative and take risks, and even bases a portion of their grades on "the quality of
their failure." He judges that quality, he says, "by the size of the risk they've taken and
the amount of insight they have generated from their mistakes."

At age 24, he received a tenure-track position at Williams, where he is also a professor of social
responsibility and personal ethics. The most important issue, he says, is what students will retain from
his
class 10 years later. "If we are in the business of transforming lives and can't give a good
answer
to that question," he says, "we're failing." To demonstrate the concept of infinity to
a
class of mostly liberal-arts students at Baylor, he sketches a trough that he describes as containing an
infinite number of Ping-Pong balls, which are falling into a barrel, 10 at a time, as a hypothetical
student
reaches in and plucks balls out at shorter and shorter intervals. "Soon you'll be working faster
than the speed of sound, than the speed of light. You black out, regain consciousness, approach the
barrel,
look inside. My question to you is, 'What's inside? What is in the barrel?'"

The students pair up at their desks and compare guesses. "It has to be infinity," one says. His
partner responds, "He's trying to trick us.... Maybe the answer's zero." Mr. Burger
writes
these and other guesses, which he draws out of more-hesitant students, on the board. He tells the class to
come back on Tuesday for the answer.

Adam Telatovich, a sophomore math major, says some of his favorite lessons in Mr. Burger's
number-theory
class follow that pattern. "He starts out with a big picture, describing these really far-out
problems,
and says this is what we're going to work up to. Then he builds up suspense and leaves the punch line
for the next class. When the class is over, we're disappointed."

Lance L. Littlejohn, chairman of the department of mathematics at Baylor, describes Mr. Burger as "a
teaching phenomenon": well organized, articulate, and engaging.

At Williams, when his students arrive for the first day of class, they sometimes tell him that they've
already had him in a course. That's because he wrote an online, multimedia math textbook used in many
classrooms nationwide. California just started a pilot program in which middle-school students are given
iPads to read his textbook and watch his lecture series.

Mr. Burger, who once planned to go to law school, discourages students from zeroing in too early on a
career. "The whole point of higher education is to mess things up and challenge basic assumptions
about
how you look at the world and fit into it," he says. "If you don't allow your education to
challenge those assumptions, there's no point in it." He advises students to choose their careers
by finding things they would do on their own for fun. "On good days," he says, "I almost
feel
it's criminal to accept money for what I do."

This fall he's stimulating discussion about good teaching across the Baylor campus by helping to
organize weekly lunch discussions for faculty members. He will also speak this week to a regional meeting
of
K-12 math teachers and plans to visit local public schools to meet with math teachers and students.
"He's wonderful in the college classroom," says Heidi J. Hornik, a professor of art history
and chair of the Cherry award committee, "but he also reaches deep down into the academic system to
make math exciting for everyone." By the way, the answer to the question about the number of
Ping-Pong
balls in the barrel: zero.

Why Johnny Can't Add Without a Calculator

Technology is doing to math education what industrial agriculture did to food: making it efficient,
monotonous, and low-quality.

When Longfellow Middle School in Falls Church, Va., recently renovated its classrooms, Vern Williams, who
might be the best math teacher in the country, had to fight to keep his blackboard. The school was putting
in new “interactive whiteboards” in every room, part of a broader effort to increase the use of technology
in education. That might sound like a welcome change. But this effort, part of a nationwide trend, is
undermining American education, particularly in mathematics and the sciences. It is beginning to do to our
educational system what the transformation to industrial agriculture has done to our food system over the
past half century: efficiently produce a deluge of cheap, empty calories.

I went to see Williams because he was famous when I was in middle school 20 years ago, at a different
school
in the same county. Longfellow's teams have been state champions for 24 of the last 29 years in
MathCounts,
a competition for middle schoolers. Williams was the only actual teacher on a 17-member National
Mathematics
Advisory Panel that reported to President Bush in 2008.

Williams doesn't just prefer his old chalkboard to the high-tech version. His kids learn from textbooks
that
are decades old—not because they can't afford new ones, but because Williams and a handful of his
like-minded colleagues know the old ones are better. The school's parent-teacher association buys them
from
used bookstores because the county won't pay for them (despite the plentiful money for technology). His
preferred algebra book, he says, is “in-your-face algebra. They give amazing outstanding examples. They
teach the lessons.”

The modern textbooks, he says, contain hundreds of extraneous, confusing, and often outright wrong
examples,
instead of presenting mathematical ideas in a coherent way The examples bloat the books to thousands of
pages and disrupt the logical flow of ideas. (For instance, the standard geometry book for Fairfax County,
which is used in schools around the country, tries to explain what a mathematical point is by analogy to
pixels on TV screens, which are not in fact point-like.) Teachers at other schools in the county have told
him that they would rather use the old books, too, but their principals would kill them. Other teachers
have
told me the same about new technologies—they, like Williams, think the technologies are ineffectual, but
lack his courage to oppose them. According to an October 2011 report, 89 percent of high school math
teachers think their students are ready for college-level mathematics. But only 26 percent of
post-secondary
teachers think the students are ready once they get there. This shortfall in mathematical preparation for
college-bound students has existed for a long time, but it is being exacerbated by the increased use of
technology. College-level math classes almost never use graphing calculators, while high-school classes
invariably do. College professors want their students to understand abstract concepts; technology
advocates
claim their products help teach students such abstractions, but in practice they simply don't. Take the
Promethean, one of the two interactive whiteboards the school uses. When I asked a Longfellow science
teacher what she could do with the Promethean she couldn't do on the blackboard, the first thing she
showed
me was a music video featuring a Rube Goldberg machine. She did not intend this ironically. The second
thing
she showed me was a drawing of an electric circuit in which wires connect a light bulb to a battery. When
the circuit was closed, the bulb lit up. This drawing goes to the heart of the technological disconnect.
Her
students like it when the bulb lights up, she says, because it reminds them of a video game. But this
shortcut is dangerous. Learning how to visualize—as required when an electric circuit is drawn on a
blackboard—is vital for developing the ability to think abstractly. You also have to make students
manipulate real circuits with real batteries, with real wires that connect them and sometimes break.
Showing
them a toy circuit in computer software is an unhappy middle ground between these two useful teaching
exercises: You neither learn how to trouble-shoot in the real world, nor do you think clearly about how
electrons work.

Math and science can be hard to learn—and that's OK. The proper job of a teacher is not to make it easy,
but
to guide students through the difficulty by getting them to practice and persevere. “Some of the best
basketball players on Earth will stand at that foul line and shoot foul shots for hours and be bored out
of
their minds,” says Williams. Math students, too, need to practice foul shots: adding fractions, factoring
polynomials. And whether or not the students are bright, “once they buy into the idea that hard work leads
to cool results,” Williams says, you can work with them. Educational researchers often present a false
dichotomy between fluency and conceptual reasoning. But as in basketball, where shooting foul shots helps
you learn how to take a fancier shot, computational fluency is the path to conceptual understanding. There
is no way around it.

The fight between those who seek a way around hard work (a “royal road to geometry,” in Euclid's
famous
phrase), and those who realize that earned fluency is the only road to understanding goes back millennia
and
became particularly acrimonious in America in the last half-century in the so-called math wars. On one
side
are education researchers like Constance Kamii, at the University of Alabama, who argues that teaching
children to add and subtract is harmful. This camp says it has insights into the way children learn that
warrant departure from traditional ways of teaching math. On the other side is the consensus of working
scientists and mathematicians as well as teachers like Williams, who notes that it took very smart adults
thousands of years to develop modern mathematics, so it makes sense to teach it to students rather than
get
them to “discover” it themselves.

**What is new to this fight is the totalizing power of technology**. A 2007 congressionally
mandated study by the National Center for Educational Evaluation and Regional Assistance found that 16 of
the best reading and mathematics learning software packages—selected by experts from 160 submissions—did
not
have a measurable effect on test scores. But despite this finding, the onslaught of technology in
education
has continued. The state of Maine was the first to buy laptops for all of its students from grades seven
to
12, spending tens of millions of dollars to do so, starting with middle schoolers in 2002 and expanding to
high schools in 2009.

The nation is not far behind. **Though no well-implemented study has ever found technology to be
effective, many poorly designed studies have and that questionable body of research is influencing
decision-makers.** **Researchers with a financial stake in the success of computer software
are free to design studies that are biased in favor of their products.** (I'm sure this bias is,
often as not, unintentional.) **What is presented as peer-reviewed research is fundamentally
marketing
literature: studies done by people selling the software they are evaluating**.

For instance, a meta-analysis of the effectiveness of graphing calculators from Empirical Education Inc.
reports a “strong effect of the technology on algebra achievement.” But the meta-analysis includes results
from a paper in which “no significant differences were found between the graphing-approach and traditional
classes either on a final examination of traditional algebra skills or on an assessment of mathematics
aptitude.” In that same paper, calculators were marginally helpful on a tailor-designed test. The
meta-analysis included the results of the specially made test, but not the negative results from the
traditional exam.

Take this gem from researchers at **SRI International. They say that standardized tests don't
capture
the “conceptual depth” students develop by using their software, so the “research team decided to build
its own assessments”—and, of course, they did relatively well on the assessments they designed for
themselves.** Another example: A recent study by the Educational Development Center compared
students who took an online algebra 1 class with students who took nonalgebra eighth-grade math. The
online
students did better than those who didn't study algebra at all (not exactly surprising). But the online
students weren't compared with those who took a regular algebra class.

**Despite the lack of empirical evidence, the National Council of Teachers of Mathematics takes the
beneficial effects of technology as dogma.** There is a simple shell game that goes on:
**Although there is no evidence technology has been useful in teaching kids math in the past, anyone
can come up with a new product and claim that this time it is effective.**

I tried using one such product, Cognitive Tutor from Carnegie Learning, which claims to be “intelligent
mathematics software that adapts to meet the needs of ALL students.” One problem asked me to calculate the
width of a doorframe, given the frame's height and a diagonal measurement of the door. After 30 seconds'
work with pen and paper, I submitted my answer: 93.7cm. But Cognitive Tutor wouldn't accept it. It wanted
me
to go through an elaborate and cumbersome series of steps to get its answer: 93.723. **This isn't
teaching math—it's teaching how to use a particular software package.** The supposed “real-world
applications” don't even reflect the real world. Show me a tape measure that allows you to measure to
one-hundredth of a millimeter.

Though serious empirical research fails to show any beneficial effects of technology, it also doesn't
demonstrate any harm. The emphasis on technology is in part damaging because of its opportunity cost, both
in effort on the part of policymakers and in terms of money. It also distracts from the real problem:
teachers who don't understand enough about math or science. This has been a problem for a long time.

A report earlier this year from Michigan State University showed that **K through eight teachers
with
no math specialization (the vast majority—more than 90 percent of K through six teachers and more than
two-thirds of sixth- to eighth-grade teachers) got only half the questions right on a base-line test
meant
to see whether they knew the material they wer supposed to be teaching.*** The good news is that
most teachers are aware of their own limitations: Only about 10 percent of the nonmath specialization K
through eight teachers said they were “confident to teach all topics” in math.

Hung-Hsi Wu, a math professor at UC-Berkeley (and another member of Bush's math panel), has been running
three-week classes for elementary and middle school teachers every summer for the last dozen years. His
“students” must wrestle with deep mathematical questions that both pertain directly to simple math and are
poorly understood by most teachers. Why does (-2)x(-3)=6? The answer isn't straightforward, and Wu takes
several pages to give it. If you don't understand it, though, you don't really understand multiplication.
But Wu has only been teaching about 25-30 teachers a summer—**there is money for new technology but
little for comprehensive teacher training.** Meanwhile, the new technology makes it easier than
ever for teachers to avoid learning their subject. **Promethean, the “interactive whiteboard”
company,
advertises as a selling point the fact that teachers can share lesson plans online. But drawing up a
lesson plan is itself educative: A teacher who plans his own lecture is forced toward mastery of the
material, but one who downloads a PowerPoint presentation doesn't have to know anything beyond how to
download the presentation. It is a mirage of efficiency: empty calories.** The real
shortfall
in math and science education can be solved not by software or gadgets but by better teachers. Programs
like
Wu's can make more teachers more like Williams. That's where efforts should be focused, not on imagined
technological solutions, which obscure more than they reveal.

In this, the

**new Common Core standards for math, which were adopted with lightening speed by 45 states and Washington, D.C., fall short.**They fetishize “data analysis” without giving students a sufficient grounding to meaningfully analyze data. Though not as wishy-washy as they might have been, they are of a piece with the runaway adaption of technology: The new is given preference over the rigorous.

**Computer technology, while great for many things, is just not much good for teaching, yet**. Paradoxically, using technology can inhibit understanding how it works. If you learn how to multiply 37 by 41 using a calculator, you only understand the black box. You'll never learn how to build a better calculator that way Maybe one day software will be smart enough to be useful, but that day won't be any time soon, for two reasons. The first is that education, especially of children, is as much an emotional process as an imparting of knowledge—there is no technological substitute for a teacher wh cares. The second is that

**education is poorly structured. Technology is bad at dealing with poorly structured concepts**. One question leads to another leads to another, and the rigid structure of computer software has no way of dealing with this.

**Software is especially bad for smart kids, who are held back by its inflexibility.**

John Dewey, the father of American education reform, defined miseducative experiences as hose that have “the effect of arresting or distorting the growth of further experience.” “Growth,” he wrote, “depends upon the presence of difficulty to be overcome by the exercise of intelligence.” The widespread use of computer technology is inimical to the exercise of intelligence. I fear this is no more than shouting into the wind, but resist it while you can, because once it gets locked in—as our food system is, to monocultures and antibiotics in factory farms—it will be even tougher to get away from.
