Setting

The study took place in general education kindergarten classrooms in three school districts in unnamed states and regions of the United States.

Study sample

The researchers randomly assigned 33 classrooms to the intervention group and 33 classrooms to the comparison group across the school districts. A total of 999 students were included in the study. Approximately 56% were eligible for free or reduced-price lunch, 38% were English learners, and 8% received special education services. Fifty percent were White, 5% were Asian or Pacific Islander, 2% were Black, and 43% did not report race. Thirty-six percent were Hispanic or Latino.

Intervention Group

Teachers in intervention classrooms used the Early Learning in Mathematics (ELM) curriculum, a comprehensive, core kindergarten mathematics program designed to address the learning needs of all students, including at-risk students in general education or Tier I classroom settings. The program consists of 120 45-minute lessons with supplemental 15-minute calendar activities. Each lesson, on average, contains four to five activities focused on one of ELM’s three areas or strands: number and operations, measurement, and geometry. Vocabulary, the fourth strand, is embedded across the other three strands. The first activity of each lesson typically introduces or reviews a math concept or skill central to the strand covered in that lesson. The second and third activities typically involve either an extension of the first activity or a review of previously learned material. The fourth activity typically targets previously learned material from a different content area. Each strand reflects the critical math content identified in the National Council of Teachers of Mathematics Focal Points for kindergarten (NCTM, 2006) and aligns with the recommendations of the National Math Advisory Panel (NMAP, 2008) as well as other experts in the field. ELM was constructed around two main principles that specifically target at-risk students: 1) it was designed to cover the most essential mathematics knowledge kindergarten children need to develop; and 2) it includes the use of research-based instructional design principles found to be effective with at-risk students in mathematics.

Comparison Group

Classrooms in the comparison group continued to use their existing kindergarten math curricula, such as Harcourt Math and Scott Foresman. Three comparison classrooms used only teacher-made materials rather than a published curriculum.

Support for implementation

The teachers in the intervention group received three four-hour ELM curriculum trainings led by the lead author of the ELM curriculum, a math teacher-educator from the University of Oregon. During the trainings, teachers received the ELM curriculum materials; and learned about the program’s key components, concepts, instructional strategies, and objectives. Teachers received continued professional development throughout the school year.
