I recently had an incredible learning opportunity to be a part of the AACTE Simulations for Secondary Science Teachers conference. The goal for the convening was to introduce participants to the simulation design process and to support them to create a secondary science simulation scenario in smaller teams. Large group zoom meetings with almost 55 participants provided a valuable opportunity to listen, ask questions, and reflect on matters that concern science teacher preparation. The convening provided just the right amount of stimulation and sense of community that probably many of us were missing due to the recent pandemic. Until now, I saw myself as a user—employing simulations to help my teacher candidates understand and practice core teaching practices. However, being a part of the scenario development team afforded an insider or “behind the scenes’ perspective.” I was able to understand the complexities, affordance, and constraints of the simulation designing process.
