Fuzzy math enthusiasts and curanderos like to point to alleged "research shows" to help peddle their wares.
Let the colonel explain.
Excerpts from a stunning report from the National Research Council posted on KTM II show that there is no there there.
Among other things, the committee finds that:
The corpus of evaluation studies as a whole across the 19 programs studied does not permit one to determine the effectiveness of individual programs with high degree of certainty, due to the restricted number of studies for any particular curriculum, limitations in the array of methods used, and the uneven quality of the studies.As a bonus, there is a list of rogue fuzzy math programs, most of them financed with tax dollars through the EHR directorate of the National Science Foundation:
• Everyday Mathematics (EM), Grades K-6 (SRA/McGraw-Hill)
• Investigations in Number, Data and Space, Grades K-6 (Scott Foresman) [ed.: also called "TERC"]
• Math Trailblazers, Grades K-6 (Kendall/Hunt Publishing Company)
• Connected Mathematics Project (CMP), Grades 6-8 (Prentice Hall)
• Mathematics in Context (MiC), Grades 5-8 (Holt, Rinehart and Winston)
• MathScape: Seeing and Thinking Mathematically, Grades 6-8 (Glencoe/McGraw-Hill)
• MathThematics (STEM), Grades 6-8 (McDougal Littell)
• Middle School Mathematics Through Applications Project (MMAP) Pathways to Algebra and Geometry, Grades 6-8 (currently unpublished)
• Contemporary Mathematics in Context (Core-Plus), Grades 9-12 (Glencoe/McGraw-Hill)
• Interactive Mathematics Program (IMP), Grades 9-12 (Key Curriculum Press)
• MATH Connections: A Secondary Mathematics Core Curriculum, Grades 9-12 (IT’S ABOUT TIME, Inc.)
• Mathematics: Modeling Our World (MMOW/ARISE), Grades 9-12 (W.H. Freeman and Company)
• Systemic Initiative for Montana Mathematics and Science (SIMMS) Integrated Mathematics, Grades 9-12 (Kendall/Hunt Publishing Company)
This list can help parents spot the offending and immensely damaging voodoo math programs in their schools so they can raise hell.
