The pattern of results was different for the two grades studied. In seventh grade, the losses made by MathForward students were lower than the losses made by comparison students. However, the differences were no different from chance.  In 8th grade, MathForward students significantly outgained comparison students. In neither grade did student gender or ethnicity affect student gains. It is difficult to interpret the differences in the results for the two grade levels in terms of implementation. The four MathForward teachers also provided instruction to comparison students, and they had access to the technology in comparison classrooms. At the same time, one of the seventh grade teachers did not receive training and was gone for most of the year, which could have explained differences in the results for different grade levels.
