Study Details
Setting
The G2ROW STEM after school program was implemented in seven Title 1 Metro Nashville Public Schools.
Study sample
Authors noted that the G2ROW STEM student sample was 57.4% female, 40.8% Black, 19.2% Hispanic, 32.5% White, and 5.8% Asian. In the sample, 43.7% of students were economically disadvantaged and 7.5% were English learners.
Intervention Group
G2ROW STEM targets high-need middle school students, particularly females and minorities who tend to be underrepresented in STEM careers, in Nashville, Tennessee. G2ROW STEM focuses on providing students with engaging, hands-on, project-based, extended-learning experiences and career-focused, applied experiences to inspire interest in STEM. Through increases in students' math and science content knowledge and academic motivation, G2ROW STEM is theorized to improve student achievement in math and science.
Comparison Group
Students in the business-as-usual comparison condition did not participate in the intervention and took the regular sequence of STEM instruction. Comparison group students had limited access to teachers who received the G2ROW STEM professional development.
Support for implementation
Teachers in G2ROW STEM received STEM-focused professional development experiences, including workshops and ongoing guidance from the district’s grant coordinator, the ability to participate in professional learning communities, access to at least one annual STEM conference, and project-based learning training and support from the Buck Institute for Education.
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.
