Abstract

Educational Research Institute of America (ERIA) conducted a one-year study ofMath Expressionsin eight schools during the 2013–2014 school year. The ITBS Mathematics was used to assess mathematics knowledge at the beginning and end of the year. Results showed that theMath Expressionsclasses made statistically significant gains at both Grades 2 and 4 over the course of the year. The increases at both grades were greater than a one-year grade equivalent increase, and the effect sizes were large. The results also showed theMath Expressionsprogram proved effective with both higher and lower pretest scoring students.
