Powering Up for the Head Start on Science Program: Using Power Analysis to Plan the Sample Size Required for a Multi-Site Cluster Randomized Trial

This intermediate session demonstrated how we conducted an a priori power analysis for a longitudinal,multisite cluster randomized trial of an early childhood science education program, then later revised it to accommodate budget changes suggested by the funder without compromising the viability of the study. We covered how the research questions, design, and analysis plan informed the power analysis approach; the software we used; and what the input parameters required actually represent.

Networks and Social Media for STEM Educators, Policymakers, and Researchers

In this pdf are STEM education networks and social media sources that may be of interest to DR-K12 grantees for the purposes of (1) disseminating knowledge and products and (2) developing partnerships with stakeholders and end users. These networks and social media were chosen because they provide researchers and developers with an opportunity to present their work to individuals that could use, promote, or improve the work.
