The long-term effects of ability grouping in mathematics: A national investigation

The complexities of school tracking have resulted in patchy explanations of how it might affect students’ academic success. We aim to develop a comprehensive understanding of tracking by investigating its long-term relationships with student outcomes. Our study is informed by sociological and social psychological theoretical perspectives that explain how this school practice may wield its influence. We use panel data from the National Education Longitudinal Survey (NELS:88) for a comprehensive analysis of the associations between ability grouping in the eighth grade and subsequent social psychological and academic variables in the 10th and 12th grades, respectively. By covering three waves of data that monitor the mathematics progress of middle school youngsters as they go through high school, we present the durable relationships of tracking. Our method compares students in tracked and untracked schools, and further partitions these students into high and low ability groups. Our results reaffirm that tracking has persistent instructional benefits for all students. Yet, high-achieving students who are tracked in middle school may suffer considerable losses in self-concept that subsequently depress their achievement, and mathematics course-taking. Implications are for a broad range theory of tracking and for further empirical work on the viability of heterogeneously-grouped classes.An earlier version of this paper was presented at the International Sociological Association (ISA) XV World Congress of Sociology, Brisbane, Australia, July 7th through 13th, 2002
