Setting

The study took place in one Head Start and one state-funded preschool program in New York State.

Study sample

Two teachers from a Head Start center and two teachers from a state-funded preschool program were randomly assigned to the Building Blocks for Math group or the business-as-usual comparison group. There were 77 children in the four classrooms; however, nine children left the classrooms during the course of the study. Final analysis samples ranged from 53 to 61 children. The majority of the children were from low-income families. The mean age of the children was 49.9 months, and 49% of the children were female.

Intervention Group

The intervention group used Building Blocks for Math for 25 weeks. Building Blocks for Math includes whole- and small-group activities and games, free-choice learning centers, ideas for integrating mathematics throughout the school day, computer software (DLM Express), and books, game sheets, and manipulatives. Teachers in the state-funded preschool program implemented the curriculum with a high degree of fidelity, whereas teachers in the Head Start center implemented it with a moderate—but adequate—degree of fidelity.

Comparison Group

Children in the business-as-usual comparison group used their typical preschool math curricula and activities over the same 25 weeks. The typical preschool math curriculum used in the Head Start comparison classroom was Creative Curriculum and math activities developed by the program. The state-funded preschool program comparison classroom continued implementing the school’s regular math curriculum.

Outcome descriptions

The primary outcome domain assessed was math, and it was measured with the Number and Geometry sections of the Building Blocks Assessment of Early Mathematics, PreK–K (see Appendix A2 for more detailed descriptions of outcome measures).

Support for implementation

Intervention teachers participated with researchers in a half-day review of curriculum materials. Project staff observed intervention teachers implementing the curriculum and were available to answer questions and discuss implementation issues with teachers as needed.

In the case of multiple manuscripts that report on one study, the WWC selects one manuscript as the primary citation and lists other manuscripts that describe the study as additional sources.
