Description¶
A four-year high-school mathematics curriculum developed by the Core-Plus Mathematics Project at Western Michigan University and distributed by Glencoe/McGraw-Hill, integrating algebra, functions, statistics, probability, geometry, trigonometry, discrete mathematics, modeling, multiple representations, and technology.
Components¶
- Core-Plus Mathematics curriculum (first edition, Contemporary Mathematics in Context): Core-Plus Mathematics is a four-year high school curriculum replacing the traditional sequence with courses featuring "interwoven strands of algebra and functions, statistics and probability, geometry and trigonometry, and discrete mathematics". The first three courses provide a common core, while the fourth prepares students for college mathematics and statistics. It emphasizes mathematical modeling and reasoning with multiple representations (verbal, numerical, graphical, and symbolic) using technology, and was developed by the Core-Plus Mathematics Project at Western Michigan University, distributed by Glencoe/McGraw-Hill. (Core-Plus Mathematics (2010))
- Core-Plus Mathematics integrated high school curriculum: Core-Plus Mathematics is a problem-based, inquiry-oriented four-year integrated mathematics curriculum for all high school students in grades 9-12. Rather than separate Algebra, Algebra II, and Geometry courses, each course is organized around connected strands of algebra/functions, geometry/trigonometry, statistics/probability, and discrete mathematics, with instruction focused on problem solving and mathematical modeling and a balanced treatment of concepts and procedures. (Core-Plus Mathematics evidence review (2019))
- Core-Plus multi-day lesson cycle: launch, small-group investigation, Checkpoint discussion, and independent task: Core-Plus units are organized around multi-day lessons cycling through instructional activities: a full-class launch of a problem situation with the teacher as "director and moderator"; small-group investigation in which students gather data, look for patterns, construct models, and make and verify conjectures with the teacher as facilitator; a whole-class Checkpoint discussion with the teacher as moderator; and an individual task with the teacher as "an intellectual coach". Materials promote collaborative small-group investigations followed by teacher-led whole-class summarizing that leads to analysis, abstraction, and further application. (Core-Plus Mathematics (2010))
Claims¶
- The evidence base for Core-Plus Mathematics is small: of 17 reviewed studies, only one met WWC standards (with reservations) and 16 did not meet standards or screens [~W]
- Core-Plus Mathematics has potentially positive effects on mathematics achievement for high school students, with an average improvement index of +15 percentile points [+W]
- The effect on SAT math scores was positive but not statistically significant, though large enough to be substantively important (effect size at least 0.25) [+W]
- Core-Plus Mathematics showed positive, statistically significant effects on ninth-grade ITED math and CPMP Course 1 and 2 posttest subtests after WWC adjustments [+W]
- One of four qualifying studies found significant positive ITED outcomes for Core-Plus Mathematics [+W]
