Synthesis of Issues and Future Directions

In this final chapter, we reflect on four themes that cut across the preceding chapters on evaluating outcomes in informal STEM education (ISE): validity, context, technology, and evaluation capacity building. We also note several topics that we hope will be addressed more extensively in future conversations about evaluation in ISE. These include the ethical responsibilities of evaluators, theory‐based approaches to evaluation, formal training and professional development pathways for evaluators, and funding opportunities and the structural landscape of the field.
