Everyday Math and Investigations are
two of the Elementary Programs given
(see #8 at above link)
The math programs listed there are the same
programs in the report
Committee for a Review of the Evaluation Data
on the Effectiveness of NSF-Supported and Commercially
Generated Mathematics Curriculum Materials
In response to our charge, 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.
Therefore, according to our charge, we recommend that:
No second phase of this evaluation review should be conducted to determine the effectiveness of any particular program or set of curricular programs dependent on the current database.
