Research
 

Building Blocks has been tested at various phases of development, from one-on-one interviews with children during early phases, to multiple classrooms randomly assigned to treatment or control conditions.

Initial Summary Research. Below are graphs showing the results of an early study in which 2 Building Blocks classrooms were compared to 2 control classrooms. Building Blocks classrooms significantly outperformed the control classrooms on tests of number (first graph) and geometry (including measurement, patterning, etc.), with effect sizes from 1 to 2 standard deviations, up to double what is considered a strong effect.

Building Blocks and TRAID I Research. In a larger study involving 36 classrooms, using the TRIAD model for curriculum implementation on a large scale, the Building Blocks curriculum was compared to an alternate, intensive, Pre-K mathematics curriculum and control classrooms with standard curricula.

   

Building Blocks classrooms significantly outperformed both other groups in mathematics achievement, with effect sizes again from 1 to 2 standard deviations.

They also significantly outperformed the control group in classroom observations of the mathematics environment and teaching.
