Mastering algebra is widely considered the gateway to higher mathematics and college readiness, but new studies question whether low-performing students benefit from exposure to the subject in middle school.
Separate studies of urban middle schoolers in California and in the Charlotte-Mecklenburg, N.C., schools suggest that placing struggling math students in algebra class does not improve their test performance on state math tests, and significantly hurts their grade point averages and the likelihood of their taking and passing higher math courses in high school.
California has led the country in efforts to introduce algebra concepts in lower grades. In 2008, the state board of education included algebra as part of the 8th grade end-of-year math test, thus requiring all students to take algebra by the end of middle school.
While pushback from the state education department and teachers鈥� unions has meant the policy has not been fully implemented, it did increase the number of students taking Algebra 1 and pre-algebra in 8th grade, according to Don Taylor, an education consultant for the California education department, and Michael Kurlaender and Heather Rose, researchers at the University of California, Davis.
The three presented findings from a study of California鈥檚 early-algebra initiative during an April 15 session at the American 91制片厂视频al Research Association鈥檚 annual conference here.
Nationwide, the proportion of students taking algebra in 8th grade nearly doubled, from 16 percent to 31 percent, from 1990 to 2007, according to the National Center for 91制片厂视频 Statistics and Mr. Taylor鈥檚 research. In California, however, algebra enrollment in that grade has more than tripled, from 16 percent of 8th graders taking algebra in 1990 to 54 percent in 2009, Mr. Taylor said.
The California researchers analyzed the coursetaking and math achievement of more than 22,000 students who started 7th grade between 2001 and 2004 in more than 20 schools in a large, unnamed urban district. They found that, for the nearly 2,400 students who performed in the lowest 10 percent on state math tests at the end of 7th grade, taking algebra in 8th grade had no significant effect on their state math-test performance at the end of 8th grade. And it caused their average GPAs to drop 7 percent, about the difference between a C and a C-minus.
鈥淲hat we can see is there鈥檚 a potential harm to a low-performing student on the GPA,鈥� said Mr. Taylor, the lead author of the study. 鈥淚t鈥檚 pretty important. The grade point average [is what] parents pay attention to, teachers pay attention to鈥攊t鈥檚 actually more salient to the kids than math [state tests]. So there鈥檚 clearly academic harm in the short term.鈥�
North Carolina Results
Although the California study is ongoing and has not yet followed the students into high school, a separate study of students in the 141,100-student Charlotte-Mecklenburg schools does.
In 2002, the Charlotte-Mecklenburg district launched a policy to change Algebra 1 from a high school to an 8th grade course.
鈥淭hey didn鈥檛 change the course in algebra. They just offered it earlier on the assumption that 鈥榳e are really holding kids back by not giving them access to algebra; we know not all students are going to pass this, but we want to have high expectations and err on the side of being more aggressive,鈥� 鈥� said Charles T. Clotfelter, a professor of public policy, economics, and law at Duke University, in Durham, N.C., who tracked the policy effects with fellow Duke researchers Helen F. Ladd and Jacob L. Vigdor.
Unlike in the California study, the Duke researchers found that even moderately math-proficient students in Charlotte-Mecklenburg who were put into early-algebra classes performed significantly worse on state end-of-year math tests. Moreover, initially low-performing students who took Algebra 1 in 8th grade were significantly less likely to take more-advanced math courses, such as Algebra 2 or geometry, later.
The Duke study, the first results of which were released as a working paper in January by the National Center for Analysis of Longitudinal Data in 91制片厂视频 Research, based in Washington, found that the achievement of students accelerated into algebra who had performed in the lowest 20 percent of 6th grade math tests declined by a full standard deviation in Algebra 1 end-of-course tests. Those students were 46 percent less likely to pass Algebra 1 by 10th grade.
鈥淲hat we find is that this policy, while it might have allowed more time to take more courses later, on net, had a negative effect on most students, especially those students who weren鈥檛 stellar in math background,鈥� Mr. Clotfelter said. 鈥淭hey went down to get students who, on net, probably should have waited a year. We鈥檙e giving this [course] and the message to [students] could have been, 鈥榊ou鈥檙e just not that good [at math].鈥�
鈥淔or whatever reason, their preparation or their confidence wasn鈥檛 sufficient to let them do well on it, and it knocked them back on their heels,鈥� he said.
In fact, the drop in scores and coursetaking was so dramatic that the Charlotte district changed its policy only two years later. The district now allows, but does not require, students to take accelerated algebra.
Neither Mr. Clotfelter nor Mr. Taylor could say whether the negative effects of early algebra came from a lack of developmental readiness or academic preparation among the low-performing students, but other research points to the latter as a prime suspect.
Other countries, such as Japan, integrate algebraic concepts into early elementary school, suggesting there is no developmental reason algebra can鈥檛 be taught earlier than high school.
In both the California district and in Charlotte-Mecklenburg, however, students were placed in formerly high-school-level courses without a transition from pre-algebra in earlier grades or accounting for students who might be performing at a 2nd grade level in arithmetic, according to a 2009 study by Tom Loveless, a senior fellow at the Washington-based Brookings Institution.
Preparation Needed
鈥淚t is possible for children in 8th grade or even younger to take algebra and do well in algebra, but not all students, and the defining characteristic seems to be prior knowledge,鈥� Mr. Loveless said in an interview.
鈥淚f a student is well prepared, algebra is a good thing regardless of the student鈥檚 age,鈥� he said, 鈥渂ut if a student is not prepared, it can be a bad thing, regardless of the student鈥檚 age. Developmental readiness shouldn鈥檛 mean a developmental mandate.鈥�
In California, the universal-algebra policy is on hold in part because of such concerns.
鈥淭he bottom line is: It doesn鈥檛 appear that being in any [algebra] courses makes a difference in terms of the math [test],鈥� Mr. Taylor said. 鈥淒oes a universal policy really fit all kids? ... If we鈥檙e creating policies that don鈥檛 improve education for every single kid, maybe we should rethink those policies.鈥�
The news wasn鈥檛 all bad for algebra at AERA; the American Institutes for Research鈥檚 鈥淏ack on Track鈥� study with the University of Chicago found that introducing online and face-to-face summer algebra programs in Chicago led to a near-doubling of credit recovery for students who failed algebra in their freshman year, said Jessica B. Heppen, an AIR principal research analyst.
