Description
This study investigated the effects of an early numeracy intervention delivered by kindergarten teachers to students identified as having mathematics difficulties. A design of multigroup growth modeling with random assignment to intervention condition was employed. Thirty-two teachers were randomly assigned to the treatment or comparison condition. A total of 71 students participated in the study, 47 in the treatment group and 24 in the comparison group. Results indicated that the treatment condition students outperformed comparison students (g* = .99) and demonstrated statistically significantly higher scores on all proximal measures of early numeracy. Also, about 80% to 100% of the variance was accounted for at the student level. Performance on distal measures was less impressive, with no significant differences between groups; the effect size was .44. Teachers rated components of the intervention highly, reflecting strong teacher satisfaction.
