ABSTRACT
At the onset of the COVID-19 pandemic, our teacher preparation program shifted to an online setting, disrupting a key feature of practice-based teacher preparation: Preservice science teachers' (PSTs) approximation of rigorous and responsive instruction during extended pedagogical rehearsals called macroteaching. Given this unplanned shock to their preparation, we examined how PSTs viewed macroteaching and their evolving participation in the teaching rehearsal. Using a situative perspective, we collected multiple forms of data. We found that while PSTs wanted to enact rigorous and responsive instruction, their participation was deeply impacted by the sudden shift to an online setting. Our analysis of video-recorded lessons confirmed PSTs' observations that their instruction became less rigorous and responsive over time. We conclude with questions about teacher preparation during the pandemic. © ISLS.
