The richness of designs and methodologies offers opportunities and challenges for evaluation. The complexity and nuance of the context of each project guide the choice of design, methods, and measures to best understand how and why effects occur. This session invites posters and oral presentations on how you navigate the choices and how well you think those choices provide understanding and evidence. Educational experiences discussed may be instruction outreach, or communication related. Collaborative presentation are welcome, as are innovative, failed, or limited attempts from which we can learn.
