A staggering amount of public funds is used to develop, support and promote CMP. One can justifiably question the integrity of studies funded through NSF that produces data to support CMP. In effect, private publishing companies are receiving government funds to produce and promote their books which local school districts would end up paying market prices for them.
This grant to Michigan State University helped "develop, field-test, evaluate, and disseminate" CMP. The two studies providing "Evidence of Student Attainment" would also be funded under this grant.
In January 1999, the American Association for the Advancement of Science (AAAS) produced "a report on middle school math textbooks" that highly support CMP and other new math books. "Project 2061" is heavily funded by NSF.
The Show-Me Center is established at the University of Missouri, Columbia to facilitate and support the implementation of new middle school mathematics curriculum like CMP. Researchers at this center published a study titled "Standards-Based Middle Grade Mathematics Curricula" supportive of CMP of course.
A new assessment tool is needed to show standards-based curricula in a better light. Balanced Assessment was created to fulfill that mission under NSF funding.
You can use the search engine in the NSF website to find out the grant trail. Search under "Connected Mathematics" and you will find a trail of money that will eventually influence local school textbook adoption committees through teacher training on favored standards-based curricula.
Other teacher training programs are funded through the Statewide Systemic Initiatives whose goal is to promote science and mathematics reform efforts in various states.
