Teacher learning through collaborative curriculum design in the midst of a pandemic: A cultural historical activity theory investigation

Collaborative design, or co-design, is an effective form of professional development that promotes teacher learning. In this study, we used cultural-historical activity theory (CHAT) to investigate how teachers attempt to resolve systematic contradictions as they co-designed and enacted a four-week science unit on COVID-19. Our findings indicated that the teachers faced significant challenges in implementing the COVID-19 unit. We also found that tensions among teachers and positioning teachers as the ultimate decision-makers were particularly useful for promoting teacher learning in the midst of a pandemic.
