Big Cities Credit Conceptual Math for Higher Scores
The two city districts that made the greatest strides in math on the latest national assessment relied on similar strategies: building students’ conceptual math skills and investing in professional development in that subject for elementary and middle school teachers.
While administrators in Boston and San Diego say that many factors were at work in their gains on the recent National Assessment of Educational Progress, they believe their approach is giving students greater ability to solve a broad variety of math problems and preparing them for more complex mathematics later in school.
“It’s not enough to memorize algorithms,” said J. Chris Coxon, the deputy superintendent for teaching and learning in the 57,000-student Boston district. “If [schools] are going to be successful in teaching math, they have to be open to students’ using different ways of solving math problems.”
Conceptual math generally seeks to cultivate students’ overall understanding of different math concepts, and lessen their reliance on memorizing set formulas and procedures. San Diego and Boston officials, as well as many math and curriculum experts, believe that approach is helping students learn to solve problems in a variety of ways, as well as preparing them for higher-level math.
Both districts’ math efforts have received grant money in recent years through the National Science Foundation. The independent federal agency has been a strong supporter of conceptual math.
NAEP provided results last month as part of what is known as the Trial Urban District Assessment. The test showed average math scores for 11 urban districts rising at both the 4th and 8th grade levels. Such gains were not echoed in reading, where performance remained mostly stagnant.
Overall, urban schools remained well below national averages in both subjects, with greater percentages of students showing only “below basic” skills. Boston and San Diego, by contrast, each had combined improvements at the 4th and 8th grade levels in math that exceeded those nationwide gains.
Still, some math researchers are reluctant to attribute the districts’ improvements in scores to a commitment to conceptual math, or any single educational strategy.
“It’s not wise to read too much into one wiggle in NAEP data,” said Tom Loveless, a senior fellow at the Washington-based Brookings Institution, who has studied state and local math scores in depth.
Researchers and school officials have debated for years the most effective way to teach math. The so-called “math wars,” which gained intensity in the late 1990s, featured supporters of a more conceptual approach to teaching math arguing from one perspective. Backers of conceptual math see evidence of its effectiveness in foreign nations, particularly in Asia, whose students routinely outperform their U.S. peers on tests of math skill.
Critics of that approach, however, said American students’ shortcomings were most likely the result of a lack of fundamental math skills.
In recent years, both camps have emphasized that a balance between conceptual math and basic skills is needed.
San Diego and Boston officials say they had no interest in revisiting those math conflicts.
Kris Acquarelli, the mathematics director for the 137,000-student Southern California district, said the school system has made changes in its approach to math over the past five or six years, some of them with the help of philanthropic and corporate backers, such as the San Diego-based technology giant Qualcomm Inc.
A central focus of San Diego’s plan has been to make math more digestible for teachers and students alike. While the district uses state-approved math textbooks at all grade levels, many elementary teachers—particularly inexperienced ones—have difficulty choosing lessons and determining which areas of math should receive the most emphasis.
To help them, San Diego officials produced a number of additional materials, including “curriculum maps,” which point to important concepts in textbook chapters; pacing guides, which help teachers balance the amount of time spent on various topics; and modules, which give teachers ideas for individual lessons.
“They help teachers navigate the curriculum,” Ms. Acquarelli said of those tools.
An overriding goal is to broaden students’ overall problem-solving skills, rather than just encouraging them to memorize formulas. “We want to make sure they learn the meaning behind the mathematics,” she said, “rather than just rules and procedures.”
San Diego is also aggressively promoting professional development, according to Ms. Acquarelli. The district arranges workshops throughout the year for K-12 teachers, some mandatory, some optional. It also has placed math resource teachers, instructors who are especially strong in the subject, in its lowest-performing elementary schools.
More Math for Teachers
The National Council of Teachers of Mathematics, in Reston, Va., has encouraged states and teacher-training programs to require more math of aspirants. Teachers need to have taken enough math courses to understand how basic concepts lead to more complex topics, NCTM President Cathy L. Seeley said.
“You need to know more than just elementary math to teach elementary math,” said Ms. Seeley, a research fellow at the University of Texas at Austin.
Michelle Collins, a 4th grade teacher at Ibarra Elementary School in San Diego, considers herself fortunate. Her master’s-degree training included an emphasis in math. But when she joined the district five years ago, many elementary instructors struggled to find the best way to use textbooks or interpret the goals outlined in California’s state standards, she recalled. The pacing guides and workshops have helped, she said.
“We talk openly about our comfort level in math,” Ms. Collins said.
How Much Progress?
Boston administrators have heard elementary teachers voice doubts about their math-teaching abilities, compared with their comfort with literacy lessons, Mr. Coxon said. The district has established math-leadership teams and math coaches at its schools, to try to provide “constant support” in the subject, he said. It has also arranged professional-development sessions focused on math at night and on weekends.
The Boston and San Diego school systems have applied similar strategies in trying to improve students’ math skills in recent years.
Emphasis on Conceptual Math
Boston uses elementary and middle school math programs that stress problem-solving skills. San Diego has devised model lessons and curricular materials.
Both districts use teachers with strong math skills to help other instructors. San Diego also posts model lessons for parents to help children.
Both districts have received millions of dollars in federal funding in recent years for math improvement from the National Science Foundation. Corporations and foundations have also contributed in San Diego.
“Teacher training is pretty much the cornerstone of whether we’ll be successful,” Mr. Coxon said.
Especially, he said, because Boston is teaching math much differently than it had a number of years ago. The district has phased in the use of two sets of curriculum programs that emphasize conceptual math. In elementary schools, it uses Investigations in Number,Data, and Space, crafted by the Cambridge, Mass.-based TERC, formerly the Technical Education Research Center, a nonprofit that specializes in math, science, and technology education. In its middle schools, the district uses Connected Math. Both programs were developed with NSF funding.
Other urban districts face challenges in trying to ensure that math is taught consistently. Chicago officials recently counted 86 different texts and editions of math textbooks in use in their K-8 schools, said Martin Gartzman, the chief math and science officer for the 427,000-student district.
Three years ago, the district launched a math and science initiative, aimed in part at fostering a more coherent curriculum. The district is now encouraging schools to adopt conceptually driven math curricula in the K-8 grades. Chicago’s scores on the urban NAEP improved, but not by a statistically significant margin.
“We’ve got a long way to go,” said Mr. Gartzman.
Those who are wary of the conceptual approach to math instruction say other factors may be behind the districts’ improved NAEP scores. Martha Schwartz, a co-founder of Mathematically Correct, which advocates the strong teaching of basic math skills, attributes San Diego’s progress in part to a greater emphasis on basic content in California’s math standards in the late 1990s.
“We have strong standards that people have pushed for,” said Ms. Schwartz, who lives in the Los Angeles area.
Mr. Loveless noted that San Diego is just one of many California districts that made headway on state math assessments in the past five years.
While she is encouraged by San Diego’s NAEP scores, Ms. Acquarelli does not believe that an allegiance to conceptual math, or any single strategy, is enough to help a district.
“The language gets in our way,” she said, referring to debates about math instruction. “We have similar goals. … Are we where we want to be? Absolutely not. We want to continue to make steady progress.”
