WWC Summary of Evidence for this Intervention
Great Explorations in Math and Science (GEMS) Space Science Sequence
Great Explorations in Math and Science® (GEMS®) Space Science Sequence is an instructional curriculum for grades 3–5 that covers fundamental concepts, including planetary sizes and distance, the earth’s shape and movement, gravity, and moon phases and eclipses. Part of the GEMS® core curriculum, GEMS® Space Science Sequence uses the solar system as the focal point for learning. The sequence uses models, hands-on investigations, peer-to-peer discussions, reflection, and informational student readings. Students complete four units, each lasting between four and nine sessions. Each unit builds upon knowledge from previous units and can be used independently or in conjunction with one another for an overall learning progression.

For more, please see the WWC Glossary entry for study rating.
Grades of the students examined in the studies that met WWC design standards, which may not reflect the full range of grades for which the intervention may be used.
The number of students included in the studies that met WWC design standards.
The sample size for the studies that met WWC design standards.
An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
For more, please see the WWC Glossary entry for improvement index.
The indicator represents the highest level of similarity found between your students and each of the high-quality studies of the intervention. Three filled in ovals indicates that at least one study that met standards was conducted on students very similar to yours. Clicking on the indicator for a study will provide information on the similarity for each of the characteristics you selected.
