Using practical training and STEM study examples, presenters provide training on planning efficient and effective impact studies in multilevel settings.
The purpose of this session is to train researchers in how to plan efficient and effective studies in multilevel settings (e.g., students nested within classrooms and schools) using several common designs. Topics include the basic concepts of multilevel design, the rationale for multilevel designs, identifying and selecting an appropriate design, practical study considerations and constraints, planning and estimating the necessary scale of studies with different designs, and strategies for reducing the sample sizes needed to conduct studies. Explication of each of these topics is anchored in the STEM-specific examples and combines lecture, software demonstrations, and practical exercises for participants in the free software PowerUP!
