Lessons learned from Successful Online Computer Science PD Completers in the Midst of a Pandemic.

The intended audience of this experience report include computer science coordinators, computer science teachers and computer science (CS) project leaders who seek to increase Latinx participation in computer science through preparing secondary teachers to teach CS. This report narrates the challenges faced and lessons learned while designing and implementing in-service teacher professional development, CS4SA-NOW, in an online format. While the pandemic affected the completion rate of most participants, CS4SA-NOW coordinators synthesized lessons learned based on two cases involving teachers who successfully completed a series of professional development CS modules. Traits identified in these teacher participants included pedagogical and ideological clarity as well as an asset-oriented mindset. Lessons learned from this project can inform future designs of in-service teacher professional development.
