An Evaluation of Number Rockets: A Tier 2 Intervention for Grade 1 Students At Risk for Difficulties in Mathematics
Key outcomes and measures
The primary outcome of interest in this study is math achievement as measured by the TEMA-3, an individually administered assessment that can detect changes in the performance of below grade-level students (Ginsberg and Baroody 2003). The test was normed on a nationally representative sample and is reported by the publisher to be well validated and widely used as a measure of math achievement (Ginsburg and Baroody 2003). The test was administered in spring 2009 to all students participating in the study.
