ABSTRACT
Promoting productive student talk and computational collaboration in small group work is challenging, especially during COVID-19 induced remote learning. This paper describes a case study of one middle school teacher's participation in a professional learning community and implementations of a physical computing unit where students created data displays to collect and analyze environmental data. The focal teacher implemented the unit twice with astonishingly better results in the second iteration. We discuss lessons from how she participated in a professional learning cycle that used reflection, adaptive support and co-designed tools that helped achieve her vision for student collaboration. © 2022 International Society of the Learning Sciences (ISLS).
