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. Then we discussed how we used both pilot

NSF and CADRE hosted a series of webinars providing an overview of the DR K-12 funding program and reviewing this year's DR K-12 solicitation. Here is a sample of some of the questions that came up during the webinars:

  1. Can you explain cost sharing?
  2. For a collaborative proposal, do we submit one or two Letters of Intent?
  3. What is the difference between STEM focus and STEM discipline?  Both are listed in the RFP.
