TERC Investigations


A National Study of Early Elementary Math Curricula
Sponsored by the U.S. Department of Education

This study takes a look at the achievement effects fo four elementary school math curriculum The four curriculum are Investigations in Number, Data, and Space: Math Expressions: Saxon Math: and Scott Foresman-Addison Wesley Mathematics. Here links to the reports the study has generated.

Review of Mathematical Soundness Background Notes for WA State Curriculum Study
W. Stephen Wilson, Ph.D.
Elementary
This review looks at the mathematical development of whole number multiplication, area of a triangle, and adding and subtracting fractions in the elementary K-5 programs from TERC Investigations, Math Expressions, Bridges in Mathematics, and Math Connects. This review found Math Expressions and Math Connects to be mathematically acceptable. TERC Investigations and Bridges in Mathematics were found to be not mathematically acceptable.
Middle School
This review looks at the mathematical development of multiplication and division for fractions and proportions in the middle school 6-8 programs for Math Connects, Prentice Hall, Holt, and Math Thematics. This review found Math Connects ranking first and Prentice Hall and Holt tied at second with Math Thematics at the bottom.

Characteristics of the TERC Investigations program
  • NSF funded
  • Multiple strategies developed
  • Standard algorithms not emphasized or developed to fluency
  • Common denominators not well developed
  • Inadequate preparation for future math
  • Group investigation work
  • Worked examples and explanations often missing from student materials
  • Good visual models
  • Transition to abstract fluency not developed
  • Student-centered
  • Constructivist approach
  • Emphasized metacognition and communication rather getting correct answer



Is this Evidence of Success?
Independent Research & Analysis A Survey of School Districts Profiled in Pearson Scott Foresman Publishers’ January 2007 Publication, "Investigations in Number, Data, and Space: Evidence for Success"i
(Data as of February 24, 2009)


Investigations in Number, Data, and Space® What Works Clearinghouse
Effectiveness: No studies of Investigations in Number, Data, and Space® that fall within the scope of the Elementary School Math review protocol meet What Works Clearinghouse (WWC) evidence standards. The lack of studies meeting WWC evidence standards means that, at this time, the WWC is unable to draw any conclusions based on research about the effectiveness or ineffectiveness of Investigations in Number, Data, and Space®.
