Subclaims¶

q3 i? At the five-month follow-up, the effect of GEMS® Space Science Sequence on the Space Science Content test was 0.19 mean difference, effect size 0.07, improvement index +3, p = 0.19, which is not statistically significant. → followup

Evidence¶

followup¶

U.S. Department of Education, Institute of Education Sciences, What Works Clearinghouse. (2012, June). Science intervention report: Great Explorations in Math and Science® (GEMS®) Space Science Sequence. https://ies.ed.gov/ncee/wwc/InterventionReport/612

q3 · i? · causal · r2

Supplemental five-month follow-up findings from the same cluster randomized trial (Appendix D) report a mean difference of 0.19, effect size 0.07, improvement index +3, and p-value 0.19 for the Space Science Content test; these findings do not factor into the effectiveness rating.

"Additional findings reflecting students’ follow-up outcomes five months after the completion of the space science sequence can be found in Appendix D."

Related Claims¶

• GEMS® Space Science Sequence produces a statistically significant positive immediate-posttest effect on the Space Science Content test for grades 4–5 students — related
• The WWC rates GEMS® Space Science Sequence as having potentially positive effects on general science achievement, with a small extent of evidence — a broader claim this one bears on
