This What Works Clearinghouse (WWC) review focuses on mathematics interventions for middle school students in grades 6 through 8 designed to impact student achievement, including curriculum-based interventions, instructional techniques, and products designed to deliver content and monitor student progress. Systematic reviews of evidence in this topic area address the following questions:
- Which interventions are effective in increasing the learning of mathematics content and skills among middle school students?
- Are some interventions more effective for certain types of students, particularly students who are at risk of failure in mathematics?
In June 2015, the WWC restructured our reviews of research on math interventions into two areas instead of three. These two review areas are Primary Mathematics (which includes interventions in which math is presented through multi-topic materials and curricula, typically used in grades K–8), and Secondary Mathematics (which includes interventions that are organized by math content area (e.g., Algebra, Geometry, and Calculus), typically taught in grades 9–12). These two areas replace the prior Elementary School Math, Middle School Math, and High School Math areas, which were organized by student grade level.
