Research Findings on CMP
A substantial number of research studies have been conducted since the release of CMP1 in 1996.
150 research articles and reports,
40 books and book chapters,
50 conference proceedings,
70 dissertations and theses, and
25 evaluation studies.
The growing body of published work includes evaluation, efficacy, student reasoning, classroom discourse, and teacher knowledge.
- Compared to their peers using conventional middle school mathematics curricula, students in CMP classrooms achieve greater conceptual gains that require mathematical modeling, mathematical reasoning, and/or careful articulation of mathematical thinking. These gains on a variety of learning measures also show that students do as well or better on procedural skills (Ben-Chaim, Fey, Fitzgerald, Benedetto, & Miller, 1998; Cai, Moyer, Hwang, Nie, & Garger, 2012; Cain, 2002; Conklin, Grant, Rickard, & Rivette, 2006; Eddy, Berry, Aquirre, Wahlstrand, Ruitman, & Majajan, 2008; Reys, Reys, Lapan, Holliday, & Wasman, 2003).
- The effects on student learning performance typically improves more after
multiple years of using CMP within schools (Bray, 2005; O’Clair, 2005; Reys et al., 2003; Tarr, Reys, Reys, Chavez, Shih, & Osterlind, 2008).
- The advantages in conceptual understanding and problem-solving persist as
students enter high school. CMP students performed better than or as well as
non-CMP students on a variety of learning measures (Cai, 2014).
- In a longitudinal study in a large urban area that followed CMP and Non-CMP
middle school students through high school found that significantly greater
percentages of CMP students than non-CMP students maintained a positive
attitude toward mathematics (Moyer, Robison, & Cai, 2018).
- The evidence on successful implementation of problem-centered curricula like
CMP points to the need for consistent and sustained professional development
and collaboration between teachers and administrators in a variety of forms (Heck, Banilower, Weiss, & Rosenberg, 2008). When students learned from CMP teachers with less teaching experience but who attended more professional development and team planning as promoted by CMP, students had higher mathematics scores (O’Clair, 2005).
