This presentation will take participants through the process of identifying the most important topics for inclusion in online/at-home labs, identifying online simulations and other online resources, considering materials students can find at home, and an example of how to share final products. Following the research-based methods of STEM teacher professional development workshops, participants will have time to discuss in small groups how to bring the ideas of this session into their own classrooms, and what they see as challenges they may face in the process. The presenter will share resources including highly regarded websites for simulation-based labs in physics and astronomy, and the physics and astronomy labs the presenter created for use during the COVID pandemic remote instruction. Participants will be given a Google Drive link to share the material they create with each other after the conference. This presentation is recommended for beginners at developing their own materials for OER usage, or anyone who wants a space to work through some ideas for developing online labs.
